JUnit5 - ExpectedException.expectCause() 等效

Question

是否有 JUnit5 等效于 ExpectedException.expectCause() (JUnit4)？
https://junit.org/junit4/javadoc/4.12/org/junit/rules/ExpectedException.html#expectCause(org.hamcrest.Matcher)

Answer 1

下面是一个例子:

public class ExpectedExceptionTest {

    @Test
    public void shouldThrow() {
        IOException exc = Assertions.assertThrows(IOException.class, this::throwing);
        Assertions.assertEquals("root cause", exc.getCause().getMessage());
    }

    private void throwing() throws IOException {
        throw new IOException(new IllegalStateException("root cause"));
    }
}

就个人而言，我更喜欢 AssertJ，它具有非常详细的描述性 exception assertions .
