I works as a Product Marketer and tech blogger at LambdaTest. So before we carry on with our Cucumber.js Tutorial, to begin writing and executing our automated test scripts using Cucumber, we need to set up our system with the Cucumber.js framework and install all the necessary libraries and packages to begin Selenium JavaScript testing. It can be downloaded via the npm manager i.e. Given: It sets the initial context or preconditions. Next, we will look at the feature file. It is intended as a brief, easy guide. The Best Selenium online courses and tutorials for beginners to learn Selenium in 2021. It is time that we get to experience a cloud Selenium Grid by getting ourselves trained on executing the test script on LambdaTest, a cross browser testing cloud. Our final project folder structure stands as below. Now that we’ve set up our system for our Cucumber.js tutorial, we will move ahead with creating our project structure and create a directory named cucumber_test. Cucumber.js is a very robust and effective Selenium JavaScript testing framework that works on the Behavior Driver Development process. WIth Cucumber.js we can interact with our webpage on the browser and make various assertions to verify that the changes we performed are actually reflected in our web application on every Browser-OS combination by utilizing Selenium Grid. Due to this reason, you will need to download Cucumber as well as Selenium Webdriver jar files. DEV Community © 2016 - 2020. We’ll write the conditions that, Given the account balance, are $1000 And the card is valid And the machine contains enough money When the Account Holder requests $200 Then the Cashpoint should dispense $200 And the account balance should be $800 And the card should be returned. It is useful only for testing of web applications. When you run the program, it will display the methods from the step definition. We begin with writing a .feature files which have the scenarios and each of these scenarios with a given-when-then structure defined. The various steps involved in creating a Cucumber application are as follows: Download the Jar files of Cucumber and Selenium and configure the build path. Cucumber Selenium WebDriver Integration Cucumber framework can be used to test the web-based applications along with Selenium WebDriver.

We will also use Gherkins keywords in our feature files which make our task easy to write user stories in a more efficient way. Making the framework very flexible and enabling us to create human-readable descriptions of user requirements as the basis for web application tests. Cucumber SpecFlow In this SpecFlow tutorial for using SpecFlow Selenium C#, we will be using SpecFlow as the BDD interpreter. This feature lets the browser check for the elements. The relevance of using a BDD framework such as Cucumber.js is often questioned by our fellow automation testers. When using Selenium with Cucumber for test automation, tests are written in feature files that can be understood by various stakeholders in an agile environment such as Business Analysts. You can leverage a Selenium Grid on-cloud. Let us try and execute our Cucumber.js script over an online Selenium Grid on-cloud. In our test case, we will open the LambdaTest website to perform certain operations on it such as launching the search engine, validating the content , etc. An important thing to note here is that, if we execute the test with only written the .feature file and nothing else, the cucumber framework will throw us an error and prompt us to define the steps. Since this test framework is developed over the Selenium interface, it empowers us with limitless capabilities in terms of Selenium JavaScript testing. Interacting with the website is the action that is performed by Selenium WebDriver. Ideally, it would take around 50 minutes to execute the test suite.

Most of the organizations use Selenium for functional testing. Selenium is a Web based automation testing tool that automates anything and everything available on a Web page. It is used for unit testing by the developers but majorly used for integration and end to end tests. Below is the working procedure of a Cucumber.js project: The next step in this Cucumber.js tutorial is to execute a sample application. You have successfully executed your first Cucumber.js script for Selenium test automation. Let’s start our Cucumber.js tutorial with a small brief about the framework. Your output should look like as shown below: So, this is how you need to write all the files and execute the program. Alternatively, the username and access key token can be easily exported using the command as shown below. In most cases, it automatically gets installed in our npm node_modules base directory as a dependency when installing other libraries. The support and hooks file is used with the step definition to initialize the variables and perform certain validations. Moreover, it collaborates the tests and makes it so legible that there is hardly a need for documentation for the test cases and can be even digested by the business users. Once the feature file is parsed, the automation code corresponding to that particular Scenario is Now we will have our first basic scenarios for visiting the website defined in the feature file followed by other scenarios. Now, let’s move further and understand some of the facts that depict the need for Cucumber in a testing framework. Let's chat.
