Salesforce Lightning Platform, used to build enterprise apps, is being increasingly adopted by admins, business analysts, consultants, architects, and especially developers.

Finally, you'll learn how to work with testing frameworks, perform debugging, and deploy metadata, and get to grips with useful tips and tricks. Each chapter concludes with sample questions that are commonly found in the exam, and the book wraps up with mock tests to help you prepare for the DEV501 certification exam.

In this chapter, you've learned every basic step of unit testing in Salesforce. These basics are necessary for any deployment process.

Salesforce recommends 75% overall coverage, but I recommend covering as much as possible. You can't test everything, such as throwing an exception during a network interruption, but most of the time, you are able to have test coverage for at least 85% for classes with more than 50 lines.

Remember, there are three important steps that you must take into account while you are creating your tests: create your own test data, perform your test scenario and execute it between the Test.startTest() and Test.stopTest() functions, and verify your retrieved result with assertions.

Happy testing!
