Remove literal boolean values from conditional expressions to improve readability. Anything that can be tested for equality with a boolean value must itself be a boolean value, and boolean values can be tested atomicly.

Noncompliant Code Example

if (booleanVariable == true) { /* ... */ }
if (booleanVariable != true) { /* ... */ }
if (booleanVariable || false) { /* ... */ }
doSomething(!false);

Compliant Solution

if (booleanVariable) { /* ... */ }
if (!booleanVariable) { /* ... */ }
if (booleanVariable) { /* ... */ }
doSomething(true);
