This is a reasonable start but it doesnt mean that all of the code was tested. java.lang.AssertionError: expected:<2.0> but was:<18.0>, at com.example.demo.calculator.CalculatorTest.testProcess(CalculatorTest.java:60). To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Line coverage would have said 100% when I was half done. Here's an example: After running unit tests, if the line starting with a.Description is not covered, it's an indication that the loop never begins iterating because the query returns no records. Code coverage numbers are often meaningless, or at best misleading. This is an excellent place to leverage automation for example, Parasofts unit testing solution provides automatic recommendations in real-time in the IDE, integrating with open source frameworks (JUnit, Mockito, PowerMock, etc.) Making statements based on opinion; back them up with references or personal experience. Making statements based on opinion; back them up with references or personal experience. It also helps us to display the coverage level of method and class implementation. I recently wrote about how easy it is to fall into the trap of chasing code coverage percentages, which led to quality discussions, so I thought I would take a deeper dive into code coverage problems and solutions. Run a configuration with coverage Code coverage is supported only for the classes and sources that belong to your current project. As soon as you manage to install the plugin, an additional option on the project execution context menu will be available for code coverage. The above code generates unit test coverage of only 99% because I can not trigger the exception. Many open-source tools that automatically generate unit tests look valuable at first because your coverage goes up very quickly. google. In case you are facing any issue while implementing share detail will try to help you. How do I test a class that has private methods, fields or inner classes? Theres not much to verify here, but we can make sure that were loading up the correct implementations of our business logic. Total code coverage equals (6/8) * 100 = 75%. The point here is that no matter what method you use to measure coverage, its important that what youre validating through assertions is meaningful. Why can't I see related data in my Apex, or why are related records showing up as `null`? Leverage automatic JUnit code coverage test case generation to quickly build and expand your tests to get meaningful, maintainable complete code coverage. This is a definitive and statistical proof that all testable code is indeed tested.
