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 that flags AssertJ isEqualTo(null) checks for simplification.

This bug checker cannot be replaced with a simple Refaster rule, 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.
