Method Detail

assertEqualsAndHashCode

public static void assertEqualsAndHashCode(Class<?> clazz,
                                           AssertEqualsAndHashCodeArguments arguments)

Asserts that the methods Object.equals(Object) and Object.hashCode() of objects created by executing the clazzes constructor work as defined by arguments.

The constructor of clazz is called multiple times using different combinations of arguments. The resulting objects equality is checked using declarations of arguments. Reflects.create(Reflect, Object...) is used to construct instances of clazz.

arguments declares two kind of valid arguments for the class constructor and if changing the argument should change the objects equality.

In addition to argument checks Object.equals(Object) is checked against null, true and the object itself while the first two are expected to differ from the object itself.

Parameters:

clazz - class to be instantiated based on given arguments

arguments - declaration of arguments and if changing arguments should change equality

assertEqualsAndHashCode

public static void assertEqualsAndHashCode(Function<Object[],?> constructor,
                                           AssertEqualsAndHashCodeArguments arguments)

Asserts that the methods Object.equals(Object) and Object.hashCode() of objects created by executing constructor work as defined by arguments.

constructor is called multiple times using different combinations of arguments. The resulting objects equality is checked using declarations of arguments.

arguments declares two kind of valid arguments for the constructor and if changing the argument should change the objects equality.

In addition to argument checks Object.equals(Object) is checked against null, true and the object itself while the first two are expected to differ from the object itself.

Parameters:

constructor - function to construct object instances based on given arguments

arguments - declaration of arguments and if changing arguments should change equality
