I am running JUnit tests that test a Spring Boot application. I have a @Before
method and an @After
one. Then I have a bunch of @Test
methods which are the actual tests.
However, my @Before
and @After
methods execute before and after each test, respectively, instead of executing once before all the tests, and once after all the tests.
Could it be that I'm also using this annotation?
@FixMethodOrder(MethodSorters.NAME_ASCENDING)
Methods annotated with the @Before annotation are run before each test.
org.junitAnnotating a public void method with @After causes that method to be run after the Test method. All @After methods are guaranteed to run even if a Before or Test method throws an exception.
JUnit provides annotations that help in setup and teardown. It ensures that resources are released, and the test system is in a ready state for next test case.
By default, the beforeAll and afterAll blocks apply to every test in a file.
This is the normal behaviour of @Before
and @After
. Quoting the documentation of @Before
, for example:
Annotating a public void method with
@Before
causes that method to be run before theTest
method.
If you want to run a method only once before and after all the tests, you can use @BeforeClass
and @AfterClass
. Quoting the documentation of @BeforeClass
for example:
Annotating a public static void no-arg method with
@BeforeClass
causes it to be run once before any of the test methods in the class.
