AssertThatIsInstanceOf

SUGGESTION

Simplification

Suppression

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

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

Samples

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

 AbstractAssert<?, ?> testAssertThatIsInstanceOf() {
-  return assertThat("foo" instanceof String).isTrue();
+  return assertThat("foo").isInstanceOf(String.class);
 }

AssertThatIsNotInstanceOf

SUGGESTION

Simplification

Suppression

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

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

Samples

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

 AbstractAssert<?, ?> testAssertThatIsNotInstanceOf() {
-  return assertThat("foo" instanceof String).isFalse();
+  return assertThat("foo").isNotInstanceOf(String.class);
 }

AssertThatIsIsEqualTo

SUGGESTION

Suppression

-  return assertThat("foo".equals("bar")).isTrue();
+  return assertThat("foo").isEqualTo("bar");
 }

AssertThatIsIsNotEqualTo

SUGGESTION

Simplification

Suppression

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

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

Samples

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

 AbstractAssert<?, ?> testAssertThatIsIsNotEqualTo() {
-  return assertThat("foo".equals("bar")).isFalse();
+  return assertThat("foo").isNotEqualTo("bar");
 }

AssertThatHasToString

SUGGESTION

Simplification

Suppression

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

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

Samples

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

 AbstractAssert<?, ?> testAssertThatHasToString() {
-  return assertThat(new Object().toString()).isEqualTo("foo");
+  return assertThat(new Object()).hasToString("foo");
 }
