== Why is this an issue?

There's no reason to use literal boolean values or nulls in assertions. Instead of using them with _assertEquals_, _assertNotEquals_ and similar methods, you should be using _assertTrue_, _assertFalse_, _assertNull_ or _assertNotNull_ instead (or _isNull_ etc. when using Fest). Using them with assertions unrelated to equality (such as _assertNull_)  is most likely a bug.


Supported frameworks:

* JUnit3
* JUnit4
* JUnit5
* Fest assert 

=== Noncompliant code example

[source,java]
----
Assert.assertTrue(true);  // Noncompliant
assertThat(null).isNull(); // Noncompliant

assertEquals(true, something()); // Noncompliant
assertNotEquals(null, something()); // Noncompliant
----

=== Compliant solution

[source,java]
----
assertTrue(something());
assertNotNull(something());
----
