Wallaby.js For Intellij V1.0.124


Wallaby.js for Intellij v1.0.124




Wallaby.js is an intelligent test runner for JavaScript that continuously runs your tests and reports code coverage and other results to your code editor immediately as you change your code. Wallaby.js uses various tricks to run your tests as fast as possible, such as runtime analysis to only execute tests affected by code changes and parallel test execution. Wallaby.js supports various testing frameworks, such as Mocha, QUnit, Jasmine, Jest, and more. In this article, we will explore how to use Wallaby.js in Intellij IDEA, one of the most popular IDEs for web development.


Installing Wallaby.js plugin




To use Wallaby.js in Intellij IDEA, you need to install the Wallaby.js plugin from the JetBrains Marketplace. You can do this by following these steps:


Download: https://taharvrioru.blogspot.com/?download=2w3qdf



  • Open Intellij IDEA and go to File -> Settings -> Plugins.



  • In the Marketplace tab, search for Wallaby and click on the Install button.



  • Restart Intellij IDEA to activate the plugin.




Alternatively, you can download the plugin from the Wallaby.js website and install it manually by following these steps:



  • Download the plugin file (wallaby-intellij-v1.0.124.zip) from the Wallaby.js website.



  • Open Intellij IDEA and go to File -> Settings -> Plugins.



  • In the Installed tab, click on the Gear icon and select Install Plugin from Disk....



  • Select the downloaded plugin file and click on OK.



  • Restart Intellij IDEA to activate the plugin.




Configuring Wallaby.js




To use Wallaby.js in your project, you need to create a Wallaby.js run configuration. This tells Wallaby.js how to run your tests and what settings to use. You can do this by following these steps:



  • In Intellij IDEA, go to Edit Configurations... from the drop-down menu in the top right-hand corner of the navigation bar, or from the Run menu.



  • In the dialog window, click on the Add New Configuration button and select Wallaby.js.



  • In the configuration settings, you can choose between two options: Automatic or Manual.




  • If you choose Automatic, Wallaby.js will try to detect your testing framework and settings automatically based on your project structure and package.json file. This option works for most common scenarios, such as using Mocha with Chai or Jest with Enzyme.



  • If you choose Manual, you need to specify a configuration file that contains all the necessary information for Wallaby.js to run your tests. This option gives you more control and flexibility over your testing environment, such as using custom compilers, preprocessors, or reporters. You can read more about the configuration file format and options in the Wallaby.js documentation. You can also use the sample calculator project as a reference for creating your own configuration file.




  • If you have a mono-repo and only want to run tests for one project, you can set the Root Path to your project folder.



  • If you want to use TypeScript or Babel in your project, you can enable the Use TypeScript or Use Babel options respectively.



  • If you want to use Webpack in your project, you can enable the Use Webpack option and specify a Webpack configuration file.



  • If you want to use React or Angular in your project, you can enable the Use React or Use Angular options respectively.



  • If you want to use Jest snapshots in your project, you can enable the Use Jest Snapshots option.



  • Click on OK to save the configuration.




Running Wallaby.js




Once you have created and saved the run configuration, you can start Wallaby.js by running your run configuration. You can do this by clicking on the Run button in the navigation bar, or by pressing Shift + F10.


The first time you start Wallaby.js, it may take a minute or two to install its dependencies. The dependencies are cached and updated automatically when required.


Once Wallaby.js is running, you will see the Wallaby.js status indicator in the bottom right-hand corner of the screen. Its job is pretty simple: when it displays a spinner, your tests are running; when it's red, you have some failing tests; when it's green, all of your tests are passing.


Viewing code coverage and test results




Wallaby.js provides real-time feedback on your code coverage and test results in your code editor. You can see this by looking at the color-coded indicators next to your code lines:



  • A green indicator means that the line is covered by at least one passing test.



  • A red indicator means that the line is covered by at least one failing test.



  • A yellow indicator means that the line is only partially covered by tests.



  • A gray indicator means that the line is not covered by any tests.




You can also hover over an indicator to see more information, such as the number of tests covering the line, the test names, and the error messages (if any).


If you want to see the code coverage and test results for a specific file, you can open the Wallaby.js tool window by clicking on the Wallaby.js status indicator (or using the standard way to open a run configuration tool window). In the tool window, you can see two tabs: Failing Tests and Wallaby Console.



  • The Failing Tests tab displays all tests that are currently failing along with the error stacks and registered console.log calls. You can use the hyperlinks in the displayed information to navigate to different places, such as the exact error line, or a failing test, or a place where something is logged to console. You can also see a diff view for failing equality assertions and snapshots.



  • The Wallaby Console tab displays some additional information about test execution progress. You can also use this tab for troubleshooting Wallaby.js issues.




Conclusion
