Method Detail

addClassLoader

public static void addClassLoader(ClassLoader loader)

forName

public static Class<?> forName(String className)

Tries to load the specified class using the context ClassLoader or if none, than from the default ClassLoader. This method differs from the standard class loading methods in that it does not throw an exception if the class is not found but returns null instead.

Parameters:

className - the class name to be loaded.

Returns:

the class or null if the class is not found.

findDeclaredFactoryMethods

public static List<ConstructorOrMethod> findDeclaredFactoryMethods(Class<?> cls,
                                                                   IAnnotationFinder finder)

For the given class, returns the method annotated with @Factory or null if none is found. This method does not search up the superclass hierarchy. If more than one method is @Factory annotated, a TestNGException is thrown.

Parameters:

cls - The class to search for the @Factory annotation.

finder - The finder (JDK 1.4 or JDK 5.0+) use to search for the annotation.

Returns:

the @Factory methods

getAvailableMethodsExcludingDefaults

public static Set<Method> getAvailableMethodsExcludingDefaults(Class<?> clazz)

Parameters:

clazz - - The Class in which the search is to be done.

Returns:

- A Set of Method excluding default methods from base class interfaces.

getAvailableMethods

public static Set<Method> getAvailableMethods(Class<?> clazz)

fileToClass

Returns the Class object corresponding to the given name. The name may be of the following form:

• A class name: "org.testng.TestNG"
• A class file name: "/testng/src/org/testng/TestNG.class"
• A class source name: "d:\testng\src\org\testng\TestNG.java"

Parameters:

file - the class name.

Returns:

the class corresponding to the name specified.

findClassesInSameTest

public static XmlClass[] findClassesInSameTest(Class<?> cls,
                                               XmlSuite suite)

Parameters:

cls - - The class to look for.
