Pattern: JUnit - unnecessary throws clause

Issue: -

Description

Checks for throws clauses on JUnit test methods. That is not necessary in Groovy.

This rule sets the default value of the applyToClassNames property to only match class names ending in 'Test', 'Tests' or 'TestCase'.

Example of violations:

@Test
void shouldDoStuff() throws Exception { }           // violation

@BeforeClass void initialize() throws Exception { } // violation
@Before void setUp() throws RuntimeException { }    // violation
@After void tearDown() throws Exception { }         // violation
@AfterClass void cleanUp() throws Exception { }     // violation
@Ignore void ignored() throws Exception { }         // violation

class SomeTest extends GroovyTestCase {
    void test1() throws Exception { }               // violation
    public void test2() throws IOException { }      // violation
}
