addClassesToModify
public final void addClassesToModify(String... classes)
Add classes that will be loaded by the mock classloader, i.e. these classes will be byte-code manipulated to allow for testing. Any classes contained in thepackagesToBeDeferred
will be ignored. How ever classes added here have precedence over additionally deferred (ignored) packages (those ignored by the user using @PrepareForTest).- Parameters:
classes
- The fully qualified name of the classes that will be appended to the list of classes that will be byte-code modified to enable testability.
