Method Detail

getMethod

protected Method getMethod(String methodName)

getMethod

protected Method getMethod(Class<?> clazz,
                           String methodName)

getMethod

protected Method getMethod(Class<?> clazz,
                           String methodName,
                           Class<?>[] parameterTypes)

assertDeepEquals

protected void assertDeepEquals(Object expected,
                                Object actual)

Compares two given objects for equality. Does a deep copy equality comparison if expected is an array.

assertDeepEquals

protected void assertDeepEquals(String message,
                                Object expected,
                                Object actual)

Compares two given objects for equality. Does a deep copy equality comparison if expected is an array.

Parameters:

message - the identifying message for the AssertionError

assertDeepEquals

protected void assertDeepEquals(String message,
                                Object expected,
                                Object actual,
                                double delta)

Compares two given values for equality, doing a recursive test if both values are arrays of the same type.

Parameters:

message - the identifying message for the AssertionError

delta - the maximum delta between two doubles or floats for which both numbers are still considered equal.

assertDeepEquals

protected void assertDeepEquals(String message,
                                Object expected,
                                Object actual,
                                int ulpsDelta)

Compares two given values for equality, doing a recursive test if both values are arrays of the same type. Uses ULPs for comparison of floats.

Parameters:

message - the identifying message for the AssertionError

ulpsDelta - the maximum allowed ulps difference between two doubles or floats for which both numbers are still considered equal.

equalFloatsOrDoublesDelta

protected double equalFloatsOrDoublesDelta()

Gets the value used by assertDeepEquals(Object, Object) and assertDeepEquals(String, Object, Object) for the maximum delta between two doubles or floats for which both numbers are still considered equal.

ulpsDelta

protected int ulpsDelta()

fail

public static void fail(String message,
                        Object... objects)

Fails a test with the given message.

Parameters:

message - the identifying message for the AssertionError (null okay)
