Class AssertJIsNull

java.lang.Object

com.google.errorprone.bugpatterns.BugChecker

tech.picnic.errorprone.bugpatterns.AssertJIsNull

All Implemented Interfaces:

com.google.errorprone.bugpatterns.BugChecker.MethodInvocationTreeMatcher, com.google.errorprone.matchers.Suppressible, Serializable

@AutoService(com.google.errorprone.bugpatterns.BugChecker.class)
public final class AssertJIsNull
extends com.google.errorprone.bugpatterns.BugChecker
implements com.google.errorprone.bugpatterns.BugChecker.MethodInvocationTreeMatcher

A BugChecker which flags AssertJ isEqualTo(null) checks for simplification.

This bug checker cannot be replaced with a simple Refaster template, as the Refaster approach would require that all overloads of Assert.isEqualTo(Object) (such as AbstractStringAssert.isEqualTo(String)) are explicitly enumerated. This bug checker generically matches all such current and future overloads.
