JUnit: @Before only for some test methods?
It is possible to achieve also via Assume from JUnit. And then you can check the method name for which you want to process @Before
.
public class MyTest {
@Rule
public TestName testName = new TestName();
@Before
public void setUp() {
assumeTrue(testName.getMethodName().equals("myMethodName"));
// setup follows
}
}
Check the topic for more insights about @Rule
.
Just move out the tests that don't need the setup code into a separate test class. If you have some other code common to the tests that would be helpful to keep, move that out into a helper class.
@Nested + @BeforeEach
Totally agree with the point of moving the related code to an inner class. So here what I have done.
- Create an inner class inside your test class
- Annotate the inner class with @Nested
- Move all the test methods you want to use in the inner class
- Write the init code inside the inner class and annotate it with @ForEach
Here is the code:
class Testing {
@Test
public void testextmethod1() {
System.out.println("test ext method 1");
}
@Nested
class TestNest{
@BeforeEach
public void init() {
System.out.println("Init");
}
@Test
public void testmethod1() {
System.out.println("This is method 1");
}
@Test
public void testmethod2() {
System.out.println("This is method 2");
}
@Test
public void testmethod3() {
System.out.println("This is method 3");
}
}
@Test
public void testextmethod2() {
System.out.println("test ext method 2");
}
}
Here is the output
test ext method 1
test ext method 2
Init
This is method 1
Init
This is method 2
Init
This is method 3
Note: I am not sure if this is supported in Junit4. I am doing this in JUnit5
