Pattern: JUnit - assert() always fails

Issue: -

Description

Rule that checks for JUnit assert() method calls with constant or literal arguments such that the assertion always fails. This includes:

• assertTrue(false)
• assertTrue(0)
• assertTrue('')
• assertTrue([])
• assertTrue([:])
• assertFalse(true)
• assertFalse('abc')
• assertFalse(99)
• assertFalse([123])
• assertFalse([a:123)
• assertNull(CONSTANT).
• assertNull([]).
• assertNull([123]).
• assertNull([:]).
• assertNull([a:123]).

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