Assertions comparing an object to itself are more likely to be bugs due to developer's carelessness.


This rule raises an issue when the actual expression matches the expected expression.

== Noncompliant Code Example

----
assertEqual($a, $a); // Noncompliant
assertSame($a, $a); // Noncompliant
assertNotEqual($a, $a); // Noncompliant
assertNotSame($a, $a); // Noncompliant
----

== Compliant Solution

----
assertEqual($expected, $a);
assertSame($expected, $a);
assertNotEqual($expected, $a);
assertNotSame($expected, $a);
