Method Detail

getDeclaredMethods

public static java.lang.reflect.Method[] getDeclaredMethods(java.lang.Class<?> clazz)

Gets declared methods of a class in a predictable order, unless @FixMethodOrder(MethodSorters.JVM) is specified. Using the JVM order is unwise since the Java platform does not specify any particular order, and in fact JDK 7 returns a more or less random order; well-written test code would not assume any order, but some does, and a predictable failure is better than a random failure on certain platforms. By default, uses an unspecified but deterministic order.

Parameters:

clazz - a class

Returns:

same as Class.getDeclaredMethods() but sorted
