Classes in org.assertj.core.api with annotations of type CheckReturnValue

Modifier and Type	Class and Description
class	Assertions Entry point for assertion methods for different types.
class	AssertionsForClassTypes Java 8 is picky when choosing the right assertThat method if the object under test is generic and bounded, for example if foo is instance of T that extends Exception, java 8 will complain that it can't resolve the proper assertThat method (normally assertThat(Throwable) as foo might implement an interface like List, if that occurred assertThat(List) would also be a possible choice - thus confusing java 8.
class	AssertionsForInterfaceTypes Entry point for assertion methods for different data types.
class	Assumptions Entry point for assumption methods for different types, which allow to skip test execution on failed assumptions.
class	BDDAssertions Behavior-driven development style entry point for assertion methods for different types.
class	BDDAssumptions Behavior-driven development style entry point for assumption methods for different types, which allow to skip test execution when assumptions are not met.
interface	BDDSoftAssertionsProvider
class	Java6Assertions Deprecated. For Android compatible assertions use the latest assertj 2.x version which is based on Java 7 only. Assertions compatible with Android. Duplicated from Assertions.
class	Java6BDDAssertions Deprecated. For Android compatible assertions use the latest assertj 2.x version which is based on Java 7 only. Android-compatible BDD-style assertions duplicated from BDDAssertions.
interface	Java6BDDSoftAssertionsProvider AbstractBDDSoftAssertions compatible with Android.
interface	Java6StandardSoftAssertionsProvider AbstractStandardSoftAssertions compatible with Android.
