Can you mock a static method PHPUnit?

Stubbing and mocking internal static methods As Sebastian Bergmann explains in one of his blogposts, since PHPUnit 3.5 it’s possible to stub & mock static methods.

Which method is used to create a mock with PHPUnit?

PHPUnit provides methods that are used to automatically create objects that will replace the original object in our test. createMock($type) and getMockBuilder($type) methods are used to create mock object. The createMock method immediately returns a mock object of the specified type.

What is mock PHPUnit?

A mock is a piece of dummy code that helps your tests run in a way that isolates specific functionality. e.g. we can mock out a function to return values in a way that makes a related piece of functionality either pass or fail a test.

How do you mock a method in PHP?

To mock a class in PHP you can use the library Mockery. The easiest way is to use mockery by using the static method and pass in the class you want to mock. $twitterMock = \Mockery::mock(TwitterClient::class); We can now use this mock object to change the response of the methods.

What is stub and mock?

Stub: a dummy piece of code that lets the test run, but you don’t care what happens to it. Mock: a dummy piece of code, that you VERIFY is called correctly as part of the test.

Why mocking is necessary in unit testing?

Mocking is a process used in unit testing when the unit being tested has external dependencies. The purpose of mocking is to isolate and focus on the code being tested and not on the behavior or state of external dependencies.

What is the difference between @mock and @MockBean?

tl;dr: Use @Mock when unit testing your business logic (only using JUnit and Mockito). Use @MockBean when you write a test that is backed by a Spring Test Context and you want to add or replace a bean with a mocked version of it.

What is difference between mock and spy?

Both can be used to mock methods or fields. The difference is that in mock, you are creating a complete mock or fake object while in spy, there is the real object and you just spying or stubbing specific methods of it. When using mock objects, the default behavior of the method when not stub is do nothing.

What are two reasons to use mock objects in unit tests?

Typically you write a mock object if:

• The real object is too complex to incorporate it in a unit testing (For example a networking communication, you can have a mock object that simulate been the other peer)
• The result of your object is non deterministic.
• The real object is not yet available.

What is the difference between mocking and stubbing?

A Mock is just testing behaviour, making sure certain methods are called. A Stub is a testable version (per se) of a particular object.

What is difference between @mock and InjectMock?

@Mock creates a mock implementation for the classes you need. @InjectMock creates an instance of the class and injects the mocks that are marked with the annotations @Mock into it.

What is the purpose of mock objects?

Using mock objects allows developers to focus their tests on the behavior of the system under test without worrying about its dependencies. For example, testing a complex algorithm based on multiple objects being in particular states can be clearly expressed using mock objects in place of real objects.
