AssertThatIsEmpty

SUGGESTION

Simplification

Suppression

Suppress false positives by adding the suppression annotation @SuppressWarnings("AssertThatIsEmpty") to the enclosing element.

Disable this rule by adding -XepOpt:Refaster:NamePattern=^(?!AssertJIterableRules\$AssertThatIsEmpty).* as compiler argument.

Samples

Shows the difference in example code before and after the Refaster rule is applied.

 void testAssertThatIsEmpty() {
-  assertThat(ImmutableSet.of(1).iterator()).isExhausted();
-  assertThat(ImmutableSet.of(2).isEmpty()).isTrue();
+  assertThat(ImmutableSet.of(1)).isEmpty();
+  assertThat(ImmutableSet.of(2)).isEmpty();
 }

AssertThatIsNotEmpty

SUGGESTION

Simplification

Suppression

Disable this rule by adding -XepOpt:Refaster:NamePattern=^(?!AssertJIterableRules\$AssertThatIsNotEmpty).* as compiler argument.

Samples

Shows the difference in example code before and after the Refaster rule is applied.

 ImmutableSet<AbstractAssert<?, ?>> testAssertThatIsNotEmpty() {
   return ImmutableSet.of(
-      assertThat(ImmutableSet.of(1).iterator()).hasNext(),
-      assertThat(ImmutableSet.of(2).isEmpty()).isFalse());
+      assertThat(ImmutableSet.of(1)).isNotEmpty(), assertThat(ImmutableSet.of(2)).isNotEmpty());
 }

SUGGESTION

Simplification

Suppression

Suppress false positives by adding the suppression annotation @SuppressWarnings("AssertThatSize") to the enclosing element.

Disable this rule by adding -XepOpt:Refaster:NamePattern=^(?!AssertJIterableRules\$AssertThatSize).* as compiler argument.

Samples

Shows the difference in example code before and after the Refaster rule is applied.

 ImmutableSet<AbstractIntegerAssert<?>> testAssertThatSize() {
   return ImmutableSet.of(
-      assertThat(Iterables.size(ImmutableSet.of(1))), assertThat(ImmutableSet.of(2).size()));

 }

AssertThatDoesNotContain

SUGGESTION

Simplification

Suppression
