When the code under test in a unit test throws an exception, the test itself fails. Therefore, there is no need to surround the tested code with a
try-catch structure to detect failure. Instead, you can simply move the exception type to the method signature.
This rule raises an issue when there is a fail assertion inside a catch block.
Supported frameworks:
- JUnit3
- JUnit4
- JUnit5
- Fest assert
- AssertJ
Noncompliant code example
@Test
public void testMethod() {
try {
// Some code
} catch (MyException e) {
Assert.fail(e.getMessage()); // Noncompliant
}
}
Compliant solution
@Test
public void testMethod() throws MyException {
// Some code
}
