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=^(?!AssertJCharSequenceRules\$AssertThatIsEmpty).* as compiler argument.

Samples

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

 void testAssertThatIsEmpty() {
-  assertThat("foo".isEmpty()).isTrue();
-  assertThat("bar".length()).isEqualTo(0L);
-  assertThat("baz".length()).isNotPositive();
+  assertThat("foo").isEmpty();
+  assertThat("bar").isEmpty();
+  assertThat("baz").isEmpty();
 }

AssertThatIsNotEmpty

Disable this rule by adding -XepOpt:Refaster:NamePattern=^(?!AssertJCharSequenceRules\$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("foo".isEmpty()).isFalse(),
-      assertThat("bar".length()).isNotEqualTo(0),

AssertThatHasSize

SUGGESTION

Simplification

Suppression

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

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

Samples

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

 AbstractAssert<?, ?> testAssertThatHasSize() {
-  return assertThat("foo".length()).isEqualTo(3);
+  return assertThat("foo").hasSize(3);
