Question

I’m writing tests for my project, and after the Unit Tests, I’m now
writing FunctionalTest.

But between the aim of Functional vs Selenium test, I’m a bit lost.

Is the functional test are just here to test if, whatever I sent to
any page (mostly in POST), it should return what I expect (200, 302,
404, 500), or is there more ? (like test if the page returned is the
one I expect (like “Login page”? or this test should be in Selenium?)

Because so far, my F tests are just a bunch of functions with an
assertStatus for each, and I feel it’s a bit useless.
I believe I can do more, but don’t know why.

What do you test in your Functional tests?

Answer 1

To answer your question, it is probably easier to look at all three types of tests alongside each other.

Unit Test – To test an individual unit of code. For example, if I had an Item class, which made up part of a eCommerce site, I would have a number of Unit tests to test that the Item class functioned as expected. This may include a test to prove that the search function returns items that match specific criteria.

Functional Test – To test that when individual units are brought together, they work together as expected. For example, for the search function to work, we would expect to send a specific RESTful URL to search for an item, which would return a specific response. It would use our controller, and model classes to execute the code and achieve the complete function.

Acceptance Test – Also known as Selenium tests are much larger set of tests. These test a scenario that a user may run through, that may cover many functional tests, that in turn may encompass many unit tests. These are concerned more with processing a user journey or a scenario, rather than individual pieces of functionality.

As for the types of asserts that are used in FunctionalTests, I have also used assertFalse and assertTrue by using the getContent method on the response object.
