AssertThatFilteredOn

SUGGESTION

Simplification

Suppression

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

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

Samples

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

 ListAssert<Integer> testAssertThatFilteredOn() {
-  return assertThat(Stream.of(1).filter(i -> i > 2));
+  return assertThat(Stream.of(1)).filteredOn(i -> i > 2);
 }

AssertThatNoneMatch

SUGGESTION

Simplification

Suppression

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

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

Samples

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

 void testAssertThatNoneMatch() {
-  assertThat(Stream.of(1)).filteredOn(i -> i > 2).isEmpty();
-  assertThat(Stream.of(3).anyMatch(i -> i > 4)).isFalse();
-  assertThat(Stream.of(5).noneMatch(i -> i > 6)).isTrue();
+  assertThat(Stream.of(1)).noneMatch(i -> i > 2);
+  assertThat(Stream.of(3)).noneMatch(i -> i > 4);
+  assertThat(Stream.of(5)).noneMatch(i -> i > 6);
 }

AssertThatAnyMatch

SUGGESTION

Simplification

Suppression

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

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

Samples

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

 ImmutableSet<AbstractAssert<?, ?>> testAssertThatAnyMatch() {
   return ImmutableSet.of(
-      assertThat(Stream.of(1)).filteredOn(i -> i > 2).isNotEmpty(),
-      assertThat(Stream.of(3).anyMatch(i -> i > 4)).isTrue(),
-      assertThat(Stream.of(5).noneMatch(i -> i > 6)).isFalse());
+      assertThat(Stream.of(1)).anyMatch(i -> i > 2),
+      assertThat(Stream.of(3)).anyMatch(i -> i > 4),
+      assertThat(Stream.of(5)).anyMatch(i -> i > 6));
 }

AssertThatCollection

SUGGESTION

Simplification

Suppression

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

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

Samples

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

 AbstractAssert<?, ?> testAssertThatCollection() {
-  return assertThat(ImmutableSet.of("foo").stream());
+  return assertThat(ImmutableSet.of("foo"));
 }
