Custom Module Writing Unit Tests in Drupal 8

Custom Module Writing Unit Tests in Drupal 8Custom module writing unit tests in Drupal 8 is really simple to do. There are many different ways of writing these test modules, and you will find that you can do it yourself or hire a professional Drupal developer to do the work for you. However, choosing between the two may be a bit difficult depending on how much time you have and if your requirements include functionality.Many custom module developers choose to go with the third option - writing the unit tests themselves. This allows them to write the unit tests to make sure that the module functions as it should and only modify things when necessary. This has the added benefit of having more control over the integration tests, as well as being able to make changes to the code to improve the module without affecting the integration tests, which could harm the module in the long run.The downside to this option is that if you decide to hire a module developer to develop your module, you will have to pay a licensing fee for each module and they will have to keep track of every change. You may not be able to use the module on more than one website at a time. For some, this is definitely worth the cost, but for others it would be an unnecessary expense.There are many different ways to test Drupal modules, and some require less code to develop and run than others. For example, the full interface can be tested through a regular web browser. But if you are a user and need to test what you see and how it looks on the screen, then you may want to look into testing the view source module.The view source module will allow you to test your custom module through a variety of different means. You can test by copying and pasting your module into a virtual machine (VM) and viewing it through a web browser. Or you can use a cron job to run a PHP script or Ajax request every 30 minutes to test changes to the code.If you are using a browser window for testing, you will have to decid e what method of testing you want to use. For example, you may be testing the module with PHP and you want to test it with XDebug. In addition, you may also want to test with Selenium or by opening and testing the test HTML files directly.To test any Drupal module you should follow some basic guidelines. When you are developing your module, test each part of the code, use a particular interface for testing, use the proper API for your module, and always test each step. Test your code with all the options available, including Test: : Job, and test what you are expecting to see rather than what you are actually seeing.
