We gone through some documentation for - ResourceResolver mock - sling mocks - JCR mocks - OSGI mock - AEM mocks But didn't get clear understanding of that, If anyone have expertise in it please do share some code demos for above topics Thanks, Gunesh Mahajan Note that this test does NOT fail because we never defined a name property in the mock JSON, that will cause the test to fail however the test execution hasn’t gotten to that point! You probably heard of Hobbes.js for automated UI and authoring testing in AEM. In some cases, you may have SCM control files in the content source tree that you do not want to be checked in to the repository. These files have the same syntax as .gitignore files. Next, create a set of methods to ensure that if any of the required data points (name, occupations, or image) are empty, isEmpty() returns true. testIsEmpty_WithoutOccupations() tests against a mock resource definition that has a name but no occupations. The example below adds a profile integrationServer, which redefines the host names and ports for the author and publish instances. Thanks Scott I have been looking for this type of test runner. To use the framework in a maven project, first you must connect to the CQ Blueprints Maven Repository and add the following dependencies: com.cqblueprints.testing test-framework 0.6.0 We came up with the JMeter Test Plan Template, especially useful if you are working in Adobe Experience Manager since you will usually be calling on AEM API as part of your test. Then, get the AEM project archetype from here. The tests validate the expected behavior of BylineImpl without while relying on a minimal set of implementation details. This use case involves calling into a static or instance method of an class in the AEM API where you are referencing a concrete class, as opposed an interface as in Use Case #1. At this point, there is nothing AEM specific about this JUnit test file. Notice that by default, all our tests are set to fail. In this case, the occupations == null is being evaluated, however the occupations.isEmpty() is not since there is no mock resource definition that sets "occupations": []. AEM Test Framework Installation. Create the following test methods to test the each of these states. Add a new resource definition to BylineImplTest.json, giving it the semantic name “empty”. However, Maven treats them as any other file that is part of the content package and does not even recognize them as JSPs. On one project, the introduction of the UberJar resulted in 30 separate dependencies being removed from the project. ctx.currentResource("/content/empty") sets the current resource to /content/empty, which we know does not have an occupations property defined.   |   This variable, ctx, exposes a mock AEM context that provides a number of AEM and Sling abstractions: The ctx object will act as the entry point for most of our mock context. In this tutorial, we’ll explore how to write Unit Tests for our Byline component’s Sling Model (created in the Creating a custom AEM Component). Note that this check allowed us to skip testing for when getName(), getOccupations() and getImage() are empty since the expected behavior of that state is tested via isEmpty(). The resulting components work in AEM all the same, but making Maven aware of the JSPs has two major benefits. The BylineImpl Sling Model will be registered into this context, Mock JCR content structures are created in this context, Custom OSGi services can be registered in this context. COnsidering this info, the developer working on the project is wondering if its wise to recommend upgrading to aem v 6.4. its recommended on a limited budget? The first test will test the condition of a brand new component, that has no properties set. ICF Next. To unit test either of these methods, a developer would use a mocking framework such as JMockit, Mockito, JMock, or Easymock to create a mock object for the AEM API referenced. If you want to inspect the result of the Maven JspC Plugin, run mvn compile in myproject/content -- after that, you will find the result in myproject/content/target/ignoredjspc). Now with the existence of BylineImplTest.json, when ctx.json("/com/adobe/aem/guides/wknd/core/models/impl/BylineImplTest.json", "/content") is executed, the mock resource definitions are loaded into the context at the path /content. core/src/test/java/com/adobe/aem/guides/wknd/core/models/impl/BylineImplTest.java. 30. Check out our guide to how AEM developers can write automated test scripts for AEM projects at different levels of code base. github "Quick/Quick" github "Quick/Nimble" Create a bin/setup script. In this chapter, we’ll write a JUnit test for the BylineImpl.java, which is the Sling Model backing the Byline component. To setup AEM instance we used Gradle AEM Multi-Project Example. Learn about frameworks and tools commonly used to test AEM code. This test must ensure the method getName() returns the correct authored name stored at the resource’s "name" property. Depending on whether you actually make use of JSP code in /libs (i.e. There are also integration tests that create a sling launchpad instance and test against sling in-process. In the new project dialog box, find a unit test project template for the test framework you want to use and select it. A framework is comprised of a combination of test tools and practices that are designed to help QA specialist test more efficiently. Looks like getting the sorted occupations works! This JAR file contains all of the public Java APIs exposed by Adobe Experience Manager. Selecting a region changes the language and/or content on Adobe.com. AEM is managed through a rich graphical interface accessible through any modern browser, enabling such desktoplike features as in-place editing of text and graphics, drag and drop of page elements, and visual design of workflows. New test methods can be added any time to the JUnit test class, this page of the wizard is merely for convenience. Maven will be used as the build tool, as this is the usual standard in AEM projects. In-container testing for AEM projects ... (CI) set-up. Refer to my prev blog to install AEM Plugin. For such scenarios, you can easily add new Maven Build Profiles to the project's POM. The UberJar only contains API interfaces and classes, meaning that it only contains interfaces and classes which are exported by an OSGi bundle in AEM. AEM Development Tools for the Eclipse IDE is shipped with a perspective that offers full control over AEM projects and instances. The dotnet test command launches the test runner console application specified for a project. However, mocking the API where possible is still recommended for performant tests. Remember, just like getName() above, the BylineImplTest.json does not define occupations, so this test will fail if we run it, since byline.getOccupations() will return an empty list. If you are not using a repository manager, then you will need to add a repository element to your pom.xml file: You can find the code of this page on GitHub. Our AEM skills test ensures that the new hires will be the right fit for the position of a programmer having the proper knowledge of AEM services, AEM framework, AEM site deployments and good experience of agile projects. We can do this in Eclipse, by right-clicking on the Java class to test, and selecting the New > Other > Java > JUnit > JUnit Test Case. Modern IDEs provide tooling that automatically checks what source code is executed over the course of the unit tests. You will also need to reconfigure the maven-resources-plugin to not include these files in the package: the filter.xml file is not applied when the package is installed but only when the package is built again using package manager. It is the recommended build management tool for AEM projects. Unit tests typically map 1-to-1 with Java classes. ... JUnit is a unit testing framework and is important in test-driven development. The result of the Maven JspC Plugin can also be bundled and deployed as part of an OSGi Bundle, but this has other implications and side effects and goes beyond our goal of validating the JSPs. Since unit tests are executed at build, outside the context of a running AEM instance, there is no such resource. testIsEmpty() tests against the empty mock resource definition, and asserts that isEmpty() is true. A client has a long term aem project they have extened with new components and extensive edit dialogs. When licensed for the AEM Communities capability, an additional API jar is necessary. Add the following new test method to BylineImplTests.java. Click the Finish button at the bottom of the wizard to generate the JUnit5 test file. Understand options for mocking or simulating AEM resources when writing unit tests. Online Privacy Policy. To achieve this, you can provide a file src/main/content/META-INF/vault/filter-vlt.xml. Bobcat. When using Java models, a common approach is to use unit tests to do this, and rely on Mockito or similar frameworks to simulate the behaviour of the AEM environment. This results in an AbstractMethodError, which in term causes init() to fail, and the resulting adaption of the ctx.request().adaptTo(Byline.class) is a null object. To achieve deletion of the classes compiled from the JSPs, we set up the Maven Clean Plugin as shown below. Since the initialization of the mock context was does in the @Before setUp()method, this will be available to all @Test methods in this Test Case, including getOccupations(). Update testIsEmpty() as follows, setting the current resource to the new “empty” mock resource definition. The first is a dependency element adding the actual dependency to your project: If your company is already using a Maven Repository Manager such as Sonatype Nexus, Apache Archiva, or JFrog Artifactory, add the appropriate configuration to your project to reference this repository manager and add Adobe's Maven repository (https://repo.adobe.com/nexus/content/groups/public/) to your repository manager. To make it easier to create new project AEM.Design Archetype can be used and it will create you project that is ready to be used by authors.. Running following command will generate a sample project You will see two plugins AEM IDE Tooling 4 IntelliJ and AEM IntelliJ Plugin. The first method is public void setUp() { .. } which is annotated with @BeforeEach. How to Set Up AEM Projects Using Eclipse Plugin. Create an AEM context using wcm.io’s AemContext in BylineImplTest.java by adding it as a JUnit extension decorated with @ExtendWith to the BylineImplTest.java file. In the wizard, select all the methods under BylineImpl, with the exception of init() which is a method used by the Sling Model internally (via @PostConstruct). Add it to the same project folder, then open the … Re-running the Coverage As, it reports that BylineImpl.java is now at 100% coverage, however there is still one branch that is not evaluated in isEmpty() which again has to do with the occupations. "empty": {...} define a new resource definition named “empty” that only has a jcr:primaryType and sling:resourceType. By completing this step, you will be able to create an automated test with Selenium WebDriver 3 and C#. Unless you are importing the product dependencies as described in Importing AEM Product Dependencies above, they also need to be added to the parent POM along with the version matching your AEM setup as described in Adding Dependencies above. when you perform vlt up and vlt ci, or when you have set vlt sync set up. We will be using AEM best practices, and use: Your browser does not support the iframe element. It creates a mock context that allows the APIs to mostly act as if they are running in AEM. testIsEmpty_WithoutName() tests against a mock resource definition that has occupations but no name. This description does not cover how to configure Maven to work with your SCM, which is described exhaustively in the Maven POM reference and the Maven SCM Plugin's documentation. mkdir bin touch bin/setup chmod +x … Update the testGetName() method in BylineImplTest.java as follows: Run the test… and it fails with a NullPointerException. For example, the archetype uses a .vltignore file to prevent the JAR file that is installed as part of the bundle from being synced back to the file system: In some cases, you may want to keep particular paths synchronized between the file system and the repository, but not have them included in the package that is built to be installed into AEM. This layer will be implemented directly in the project’s repository and contains the test … Run the test, and again we pass! Copy the following code to the myTestSuite.js file then save the file: new hobs.TestSuite ("Experience Content Test Suite", {path:"/etc/clientlibs/myTests/myFirstTest/myTestSuite.js"}) You can also generate OSGi Service Component Runtime (SCR) and OSGi Metatype information. For local development, the same tests can be run against an already running AEM instance to speed up the test process. Ok great! Recommended practice to build AEM projects is to use Apache Maven tool. Instead, they can test the code against to the page content using wcm.io’s AEM Mocks. Works like a dream on my windows environment but am having issues on Mac. Project Archetype. This use case can be handled with the UberJar. Ran into a known issue when targeting net451 where dotnet test cannot find dotnet-test-xunit.exe Solved that by having the test project target netcoreapp1.0 Now cannot get the watcher to work. There are four dependencies required: The JUnit5, Mockito and AEM Mocks test dependencies are automatically added to the project during setup using the AEM Maven archetype. This plugin provides many features that make AEM development quicker and easier. Update BylineImplTest.json to include a list of occupations, and they will be set in non-alphabetical order to ensure that our tests validate that the occupations are sorted by getOccupations(). Create a new JSON file at core/test/resources/com/adobe/aem/guides/wknd/core/models/impl named BylineImplTest.json with the following content: This JSON defines a mock resource definition for the Byline component unit test. We will make use of the example demo.example.com domain and content that are available when using AEM Multi-Project … The following is a typical list of patterns to include from SCM. When writing unit tests, there are two primary approaches: In this tutorial, the latter approach is used (as we’ve already created a working BylineImpl.java in a previous chapter). There are remote tests that can be deployed to a running CQ5 server and executed remotely (using curl for example). The content module contains a file src/main/content/META-INF/vault/filter.xml which defines the filters for the AEM package that is built by Maven. E.g., if you are using git, you can add these to your project's .gitignore file. Remember we load BylineImplTest.json into ctx before the execution of each test method in @setUp, so this new resource definition is immediately available to us in tests at /content/empty. To run AEM, you need the AEM Quickstart, either Standalone or Web Application Archive (WAR) form. Adobe Cloud Manager integrates unit test execution and code coverage reporting into its CI/CD pipeline to help encourage and promote the best practice of unit testing AEM code. Now that we have a basic mock context setup, let’s write our first test for BylineImpl’s getName(). These samples use JMockit, but for this particular use case, the difference between these frameworks is largely syntatical. A general rule of them when working with unit tests is to create the minimal set of mock content, context, and code required to satisfy each test. Remember that this method must return an alphabetically sorted list of occupations (descending) stored in the occupations property. Users of other build systems (for example, Apache Ant, Gradle) should follow similar steps, adapted to the specific syntax of their chosen tool. Click Next, choose a name for the test project, and then click Create. It also contained a MANIFEST.MF file containing the correct package export versions for all of these exported packages, thus ensuring that projects built against the UberJar have the correct package import ranges. It will house private dependencies like our test frameworks. Unit tests are build-time tests written in Java that verify expected behavior of Java code. Right-click on BylineImplTests.java > Run As > JUnit Test, JUnit view at Eclipse > Window > Show View > Java > JUnit. Two things are required to enable this setup: Below dependencies need to be added to the content modules's POM. bslokesh-October 14, 2014. The JUnit5, Mockito and AEM Mocks test dependencies are automatically added to the project during setup using the AEM Maven archetype. Right-click the myFirstTest node and click Create > Create File. The file that is created by the Maven archetype looks like this: This file is used in a number of different ways: Depending on your application's requirements, you may want to add to these paths to include more content, such as: To add to the paths, add more elements: If you have files that should be added to the package that is built by the content-package-maven-plugin but that should not be synchronized between the file system and the repository, you can use .vltignore files. These samples use JMockit, but for this particular use case, the difference between these frameworks is largely syntatical. In Solution Explorer, select the solution node. It is also possible to configure these repositories in your Maven settings.xml file. Adobe Experience Manager (AEM) is an enterprise-grade content management platform with a wide array of powerful features. Apache Maven is an open source tool for managing software projects by automating builds and providing quality project information. AEM is a Java-based platform and Maven is the standard way to manage code for an AEM project. The actions performed in the AEM Authoring environment are quite common and repeatable for development/testing and the AEM UI controls for such actions are quite standard. Post questions and get answers from experts. Eclipse even color codes the lines of code: In the coverage report it’s been identified the branch the executes when the occupations field is null and returns an empty list, is never evaluated. Since in order to even instantiate the Byline Sling Model, this mock context must be in place, we can add it to the @Before setUp() method. They provide a standardized test language and reporting structure for applications under test and can reduce test maintenance costs. Launch Eclipse and create a Maven project. #4) Keyword Driven Testing Framework. Ensure the Coverage summary view is opened (Window > Show View > Other > Java > Coverage). The test code in this post is written with jUnit5, although most of the concepts here apply to jUnit4 as well. While a great library, there are not many resources online for how to test it when used inside your code. With the UberJar, you can compile project code which depends upon AEM APIs (and the APIs used by the projects mentioned above). Because the UberJar contains only APIs, it is not executable and cannot be used to run Adobe Experience Manager. Our test file has a number of auto-generated methods. Because of this, we must review and understand its public methods’ behaviors, but also some of its implementation details. For development purposes, you may want to have the contents of this path available in your file system, so that e.g. When working with Source Configuration Management (SCM), you want to make sure that. It includes limited external libraries as well, specifically all public APIs available in AEM which come from the Apache Sling, Apache Jackrabbit, Apache Lucene, Google Guava, and two libraries used for image processing (Werner Randelshofer's CYMK JPEG ImageIO library and the TwelveMonkeys image library). TDD in the context of AEM requires a level of expertise and is best adopted by AEM developers proficient in AEM development and unit testing of AEM code. This should be running in the background. To compile JSPs in Maven's compile phase, we use Apache Sling's Maven JspC Plugin as shown below: Our primary goal, as stated above, is to validate the JSPs and make sure that the build process fails if they contain errors. View the finished code on GitHub or review and deploy the code locally at on the Git brach unit-testing/solution. Avoid the temptation of building out complete mock context before writing the tests, as it often results in unneeded artifacts. This makes sense because the "name" property has not been added to mock /content/byline resource definition in BylineImplTest.json, so let’s add it: Update BylineImplTest.json to define "name": "Jane Doe". Name the file myTestSuite.js and click OK. A typical case is the /libs/foundation path. AEM Developer Tools for Eclipse is an Eclipse plugin based on the plugin for Apache Sling under the Apache License 2 license. With some limitations, you can also write and execute unit tests. There are three main types of testing for AEM applications: functional testing, automated testing, and load testing. Run the JUnit Test Case by right-clicking on the class name, and Run As > JUnit Test. For this condition, we can re-use /content/byline which represents a fully configured Byline component. Collections.emptyList(); sets the expected value to an empty list. A. its running with aem version 5.6 and is using the classic ui. Let’s move on and test getOccupations(). Most code written for AEM relies on JCR, Sling or AEM APIs, which in turn, require the context of a running AEM to execute properly. The subsequent methods are the test methods themselves and are marked as such with the @Test annotation. This example uses the AEM project archetype 19 to generate a new AEM project, Junit 4 will be used as the testing framework, Mockito 2.27.0 will be used as the mocking framework, and AEM Mocks will be used to mock AEM objects and AEM objects. The comments in each entry below show the package to search for in the Dependency Finder. E.g. Process to Set up ExtentReport: Install and set up Java on your system. Create a class variable for AemContext that can be used for all of the test methods. This can be easily solved by creating another test method that is used a mock resource definition that sets the occupations to the empty array. Lastly, write a test to ensure that isEmpty() returns false when the component is properly configured. The following tutorial to create a development environment, is the first step in Creating your own test automation framework using Selenium Webdriver 3, Visual Studio 2015 and NUnit. The extension takes care of all initialization and cleanup tasks required. This will run the unit tests within this file and provide a report indicating the code coverage. Coverage with testGetOccupations_WithoutOccupations(). Now onto the problem: For a continuous integration set-up, the AEM instance is created, started and shut down as part of the Maven build cycle. Re-run the test, and again it fails, but this time the message is clear why its failed. testIsEmpty_WithoutImageSrc() tests against a mock resource definition with a name and occupations, but sets the mock Image to return a blank string when getSrc() is invoked. Now setup Eclipse. NOTE: context.loader is used to load page content in JSON format and it allows us to test the code against it. To view these dependencies, open the Parent Reactor POM at aem-guides-wknd/pom.xml, navigate to the .. and ensure the following dependencies are defined: Open aem-guides-wknd/core/pom.xml and view that the corresponding testing dependencies are available: A parallel source folder in the core project will contain the unit tests and any supporting test files. Since the provided mocks cannot accommodate our code, we must implement the mock context ourselves For this, we can use Mockito to create a mock ModelFactory object, that returns a mock Image object when getModelFromWrappedRequest(...) is invoked upon it. You can view and run Hobbes.js test … Install both and restart IDE. The dotnet test command is used to execute unit tests in a given project. This next step helps with the auto-generation of test methods. You can run mvn clean install -DskipTests=true if you want to build your AEM project without running Java or Javascript tests; this setup enabled to do so. if you include /libs/foundation/global.jsp, you can use the following configuration for the maven-resources-plugin instead of the configuration above which completely skips over /libs. Testing isEmpty() is interesting as it requires testing for a variety of conditions. First, here's what you'll find: JMeter Test Plan Template features Return true when occupations are null or empty, Return true when the image is null or has no src URL, Return false when the name, occupations, and Image (with a src URL) are present. In the past, developers had to manage a relatively large number of individual dependencies to different AEM libraries and when each new API was used, one or more individual dependencies had to be added to the project. As with SCR Generation, if your code extends a base class (abstract or concrete) from the AEM API, you must use the UberJar in order to test it. We will effectively test the init() by testing all other methods, as the other methods rely on init() executing successfully. The AEM environment consists of 1 Author and 2 Publish instances with Dispatcher in front of them. Note that we want to override the modelFactory.getModelFromWrappedRequest(..)behavior defined in setUp() to ensure the Image object returned by this call is null. To unit test either of these methods, a developer would use a mocking framework such as JMockit, Mockito, JMock, or Easymock to create a mock object for the AEM API referenced. This document describes how to set up an AEM project based on Apache Maven. It’s OOTB UI and authoring testing framework shipped with AEM. If this file exists, it will be used by the VLT tool, e.g. Next screen will show you the installed plugins. testIsEmpty_WithoutImage() tests against a mock resource definition with a name and occupations but sets the mock Image to return to null. To facilitate this, wcm.io’s AEM Mocks creates a mock context that allows these APIs to mostly act as if they are running in AEM. Create a new @Test method in BylineImplTest.java that uses this new mock resource, asserts isEmpty() returns true. Eclipse provides a quick view of how much of each class and method are covered by the unit test. Re-run the test, and testGetName() now passes! This tutorial covers the implementation of a Unit Test that validates the behavior of the Byline component’s Sling Model, created in the Custom Component tutorial. Typically each public method of the Java class has at least one corresponding test method, validating its behavior. ... Before you create your utilities and verifications, it’s crucial you get a smoke test project set up. It’s used to give our contributors (and us) a simple way to set up the project and the dependencies. While unit testing code is a good practice for any code base, when using Cloud Manager it is important to take advantage of its code quality testing and reporting facilities by providing unit tests for Cloud Manager to run. Add a new mock resource definition to BylineImplTest.json that is a copy of “without-occupations” and add a occupations property set to the empty array, and name it “without-occupations-empty-array”. Generate a new project using the AEM Archetype. Drilling into the class and methods gives clearer indications of what parts of the file are tested, and which are not. In the setUp(..) method, which is executed prior to each @Test method, define a common mock testing state: The JSON files that represent the mock resource structures are stored under core/src/test/resources following the same package pathing as the JUnit Java test file. For example, to make /libs/foundation available locally for development, but only include /apps/myproject in the package, use the following two files.
