我可以使用TestInfo接口从@BeforeEach中排除单个测试吗

Question

我一直在寻找从@BeforeEach中排除单个测试的方法。在我之前的问题中，有人建议我使用TestInfo接口：我可以从JUnit5中的@BeforeEach中排除一个单独的测试吗？

我对这种解决方案很感兴趣。然而，我试过了，但对我不起作用。有可能这样做吗？我的代码有错吗？

@ExtendWith(MockitoExtension.class)
public class MockTest {
int a = 1;
int b = 1;
int c = 1;
@BeforeEach
void init(TestInfo info) {
if (info.getDisplayName().equals("testTwo"))
return;
a=5;
b=10;
c=15;
}
@Test
void testOne(){
int expected = 15;
assertEquals(expected,a+b);
}
@Test
void testTwo(){
int expected = 3;
assertEquals(expected,a+b+c);
}
}

testTwo((的输出：

org.opentest4j.AssertionFailedError: 

预期：3实际：30

似乎是一种尝试单独排除的黑客方法。为什么不使用@Nested？

@ExtendWith(MockitoExtension.class)
public class MockTest {
int a = 1;
int b = 1;
int c = 1;
@Nested
class InitializedTests{
@BeforeEach
void init(TestInfo info) {
a=5;
b=10;
c=15;
}
@Test
void testOne(){
int expected = 15;
assertEquals(expected,a+b);
}
}
@Nested
class StandaloneTests {
@Test
void testTwo(){
int expected = 3;
assertEquals(expected,a+b+c);
}
}
}
