Field Details

COMPARATOR

private static final Comparator<ITestNGMethod> COMPARATOR

A Custom comparator that helps in ITestNGMethod ordering keeping in mind the class hierarchy. Here's how the comparator works:
Lets say we have two method objects o1 and o2.
o1 is associated with MyClass and o2 is associated with AnotherClass.

• -1 is returned if MyClass is the parent of AnotherClass
• 1 is returned if AnotherClass is the parent of MyClass
• 0 is returned otherwise if MyClass and AnotherClass are the same i.e., both methods belong to the same class.

Working of isAssignableFrom
Lets say we have :

1. interface Oven
2. Microwave implements Oven

1. microwave instanceof Oven : returns true
2. Oven.class.isAssignableFrom(microwave.getClass()) : returns true

Method Details

findMethodListSuperClass

private static List<ITestNGMethod> findMethodListSuperClass(Map<Class<?>,List<ITestNGMethod>> map,
 Class<? extends ITestNGMethod> methodClass)

Look in map for a class that is a superclass of methodClass

findSubClass

private static Class<?> findSubClass(Map<Class<?>,List<ITestNGMethod>> map,
 Class<? extends ITestNGMethod> methodClass)

Look in map for a class that is a subclass of methodClass

fixMethodInheritance

public static void fixMethodInheritance(ITestNGMethod[] methods,
 boolean before)

Fix the methodsDependedUpon to make sure that @Configuration methods respect inheritance (before methods are invoked in the order Base first and after methods are invoked in the order Child first)

Parameters:

methods - the list of methods

before - true if we are handling a before method (meaning, the methods need to be sorted base class first and subclass last). false otherwise (subclass methods first, base classes last).

dependencyExists

private static boolean dependencyExists(ITestNGMethod m1,
 ITestNGMethod m2,
 ITestNGMethod[] methods)

internalDependencyExists

private static boolean internalDependencyExists(ITestNGMethod m1,
 ITestNGMethod m2,
 ITestNGMethod[] methods)

equalsEffectiveClass

private static boolean equalsEffectiveClass(ITestNGMethod m1,
 ITestNGMethod m2)

sortMethodsByInheritance

private static void sortMethodsByInheritance(List<ITestNGMethod> methods,
 boolean baseClassToChild)

Given a list of methods belonging to the same class hierarchy, orders them from the base class to the child (if true) or from child to base class (if false)
