![]() You may be using variables form inside the loop after it. But by testing these 3 versions you account for ![]() That it not something you have to consider. ![]() If the loop is never reached if the input array is empty, then Whenever you have a loop in your code, whether it’s a for, foreach, while or do while loop. $this->assertFalse($session->isStarted()) ĩ: Test 3 (or more) variants of your loops 'A session was already started before this test ran.' * function testNewSessionDoesNotStartAPhpSession(): void You wouldn’t be the first (or the last) to accidentallyĪssign the wrong property in the constructor, or read the wrong property in a getter.Įspecially if it is a large pull request, these are the kind of thing that get looked over. Generally the time you spend on writing the simple tests isn’t what is going to slow you down.Įven a test like this is worth writing. If the code is worth writing, its worth testing. The code is either impossible to test, or it is so simple that it is not worth testing. ![]() To people who don’t like tests, they always fall in one of two categories. Ideally both the source and test folder should be checked in the same process. If your test suite is stricter, then the error you get there may not show up in your normal code. So, since you won’t be able to do that in your normal code, you don’t have to worry about it in your tests.Īn important thing to note here, is that you should be running your test suite on the same levelĪs your ‘normal’ code. If, in your tests you pass a class to this method, just to see what happens, that would give you an error in your static analysis tool. This method takes either a string, or a resource, and uses that as the data to send. A simplified version of our method looked like this: Not too long ago we had to test a method that used an external SDK, which was using a lot of global state. This should help other better understand what is going on in your test suite. The difference here is that you don’t test how many times a method is called, or with what params.īy using createStub you starting using the correct terminology for your test doubles. Or it means that you only configure that a method will return certain values when called. This can mean that it isn’t actually used in the part you are testing. Must be called exactly once, and you can configure with what params the method should be called.Ī stub on the other hand is an object that is just a placeholder. While in general testing terms there are mocks, stubs and spies.Ī mock object is an object where you configure expectations on. Which solved one of the issues with mocking in PHPUnit.īefore that, everything was a mock. I wrote a post about this already, so check that out right Running PHPUnit tests within PhpStormĬonfigure PhpStorm to run Drupal's PHPUnit tests.When you need to test a lot of variations of a test, using a data provider will save you fromĬopy pasting the same set up code everywhere.
