![]() ![]() In order to isolate your object under test, it’s usually necessary to mock out all of the other objects that it interacts with. Simply, a mock object is a “fake” version of a code object (usually an object in the OO sense as well). ![]() PHPUnit natively provides mock objects with enough functionality to supply both predetermined inputs to the code under test and also to verify whether certain methods were called. Here we’ll take a look at a few strategies for properly isolating the code that you are trying to test in order to prove that it works without having to test your entire system.ĭepending on what you read, different distinctions are drawn between mock objects, fake objects and stubs. Writing unit tests for any application relies upon being able to isolate the object under test, which can be difficult in these situations. You should be able to test any function or method now that doesn’t rely on making calls out to other methods or functions – which is of course very few, as most applications are a complex combination of methods and, in PHP’s case, functions.Īuthor: Kendrick Curtis, Stainless Software, The importance here is that you get your core logic, the parts of your code that are integral to your application tested at a unit level.In my previous column PHP Unit Testing with PHPUnit,I showed how to set up PHPUnit and how to run a few simple tests. ![]() It helps you build a picture and test for what your customers are expecting to see/use in your application. Don't get me wrong, acceptance testing is extremely important as well. Mike Cohn coined the term about a testing pyramid, Martin Fowler has written more on the subject here īut it seems like it'd be easy for something like a misconfigured query scope to lead to false green on feature tests. Your tests should be unit test heavy and acceptance testing light. They are usually the ones that break the most often as 1 developers idea of what looks right or the correct flow might not be what another developer thinks is right. Personally I wouldn't leave it down to just one type of testing, acceptance tests can be flaky. I guess another option would be to leave coverage of them up to feature tests, It's sometimes referred to as subcutaneous testing, you can do some more reading on the topic here The aim here is to test everything in your application up until your UI layer which from your original text the OPs original text I think is what you're currently doing. Yeah, this is fine, just make it consistent across your team. I assume an integration directory is where I should move tests concerning my eloquent models? ![]() A relatively newcomer to the game is cypress, I've used it in a recent project and was impressed by its ease of use, especially compared to selenium. Laravel has one built-in called dusk, although the industry standard is Selenium. This is moving more into the integration/acceptance testing area rather than unit testing.Īlthough PHPUnit can do some level of integration testing and it can do acceptance testing to a certain degree but it certainly isn't as robust as a dedicated solution. If your unit test is hitting the database it's very likely your unit test isn't testing a single unit of code.įrom what I can gather from your post, although it's not fully clear, you're trying to test multiple blocks of code in a single test. If your single piece of code does need some kind of object to work with then you need to look into mocking that object to run your tests against that. Eloquent is extremely well tested and doesn't need any more unit tests. Whether you choose to to this data seeding with a seeder or "manually" in the test, up to you, opinions on this vary greatly.Īs mentioned in another post on this thread, your unit tests shouldn't be hitting a database for any reason. This way the test clearly shows what is being inserted, instead of you (or someone else) having to guess at a later point. To make things more speedy, ensure you're using sqlite in your tests # phpunit.xmlīe aware though SQLite does not have the same feature set as MySQL so if your migrations are doing something special (like if your application is using a spatial column type like POINT) you'll have to switch your test suite to use MySQL as well.Īs for seeding your database, I'd argue you should seed your database with the required data for a given test right there in the test. Luckily, the RefreshDatabase trait handles this for you ![]()
