Recommendation type: No assertions

Configurable in Preferences: Yes

Filter category: Assertions

Description

UTA displays this recommendation when a test does not include any assertions. Each JUnit test should have at least one assertion. Each assertion should have a message that explains why the test failed to facilitate maintaining and debugging the test.

UTA does not display this recommendation for tests that have an expected exception specified with the @Test(expected=...) annotation, the assertThrows() method, or @Rule ExpectedException.

Example

public class Foo extends TestCase {
    public void testSomething() {

        Bar b = findBar();
        // This is better than having a NullPointerException
        // assertNotNull("bar not found", b);
        b.work();
    }
}
