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

Modifier and Type	Class	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.
class	Java6Assertions	Deprecated. For Android compatible assertions use the latest assertj 2.x version which is based on Java 7 only.
class	Java6BDDAssertions	Deprecated. For Android compatible assertions use the latest assertj 2.x version which is based on Java 7 only.
