Symfony2 RESTful应用程序-测试

Question

Which way is better to do tests in Symfony2 RESTful application or in any others applications.

Example: I want to test PostController , which contains actions: getPostsAction() , getPostAction() , putPostAction() , postPostAction() , deletePostAction() .

So I've created class PostControllerTest .

Question is:

a) Should I create individual test for each action? Ex - testing updating:

• first load posts from fixture
• get id of one of this added posts
• update this post through PostController@putPostAction
• check updating result with entity manager

b) Or test few actions in one test(every through controller)? Ex:

• first test creating
• next listing(expecting added post)
• updating
• listing(expecting updated post)
• deleting
• listing(expecting 0 rows).

I think first option is OK, because I test only one controller action in one single test. I exactly know what I want to test. But in second case I can do tests faster and don't need use fixtures and entity manager.

Which way will be better and why?

Answer 1

I cannot say for sure what's the best solution for you but I think a good idea is to make it more functional as you said. You can make your tests to follow a flow, like:

• Create user
• Update user
• Delete user

Making a complete cycle without leaving trash data.

I have an opensource project which I do exactly like this, and I also use some traits to help me on creating objects and validating responses from my Rest calls. You can see a real test in here: https://github.com/renatomefidf/sammui/blob/master/src/Renatomefi/TranslateBundle/Tests/Controller/ManageControllerTest.php

By using the @depends annotation from phpunit you can determine the flow and make sure you have a logical path for your tests.

I hope this helps you, and if you have more questions let me know!
