case "a": Is it possible to control it remotely? My co-worker disagrees and thinks this protects us against unexpected behavior caused by new values being added to MyEnum. Noisy and/or meaningless tests mean that you cant rely on your test suite, not for refactoring, and not even for release. While writing unit tests, the main emphasis should be given on actually testing the logic and behavior of the block by designing input data to ensure the code path executes and writing assertions to make sure the code's behavior is as expected. enjoy another stunning sunset 'over' a glass of assyrtiko. Set the test runner. But how do we figure out which code is the most complex? Ideally, the assertion is checking that the code is working properly, and the assertion will fail when the code is working improperly. However, Jacoco reports 0% coverage. I often use enum types in my code with a switch to apply logic to each type. Depending on your language, you should just be able to pass in a garbage value to the Error constructor. (That code is actually currently unreachable, but its a good practice to include a default clause in case future changes trigger unexpected situations.). What is the Russian word for the color "teal"? @CodesInChaos I'm using Resharper with DotCover. Can I use my Coinbase address to receive bitcoin? How can I rewrite Error() so that all newly added enums that are not added to the switch will be caught somehow by the programmer, and also be covered by tests. Your type is always "turbine", so just that case is tested. If code coverage is an issue for you, make sure youre measuring it right, and measuring all of it from all the tests you run. Thats where JaCoCo comes in. We dont want to write tests that repeatedly cover the same areas of the code while ignoring other parts of the code. I didn't -1 you, but I figure it'd be because of your attitude ;), switch statement - handling default case when it can't be reached. 5 Answers Sorted by: 4 Depending on your language, you should just be able to pass in a garbage value to the Error constructor. Unexpected uint64 behaviour 0xFFFF'FFFF'FFFF'FFFF - 1 = 0? The proxy object is just a way to get access to protected methods. Try adding another type to MyEnum. Next is the way we work through the test cases. Run/Debug configuration: JUnit | IntelliJ IDEA Documentation A JUnit test case is the set of codes which ensure that our program code works as expected or not. English version of Russian proverb "The hedgehogs got pricked, cried, but continued to eat the cactus". Which ability is most related to insanity: Wisdom, Charisma, Constitution, or Intelligence? To learn more, see our tips on writing great answers. How about saving the world?
