- Method Detail
  - delegateType
```
Class<T> delegateType()
```
    Returns the type to delegate to.
    
    Returns:
    
    The type to delegate to.
  - wrap
```
T wrap(T delegate)
```
    Creates the object to test.
    
    Parameters:
    
    delegate - The delegate to test against.
    
    Returns:
    
    The created object.
  - methods
```
Stream<DelegateTests.DelegateMethod<T>> methods()
```
    Returns the delegate methods to test.
    Note: the result should not include a delegate method for Object.equals(Object), Object.hashCode(), private methods, static methods or final methods.
    
    Returns:
    
    A stream with the delegate methods to test.
  - testDelegates
```
@TestFactory
@DisplayName("delegates")
default Stream<DynamicTest> testDelegates()
```
    For each method returned by the object returned by methods(), test that the result of wrap(Object) delegates to its argument.
    
    Returns:
    
    A stream with the tests, one per method.
  - method
```
default DelegateTests.DelegateMethod<T> method(String name)
```
    Returns a delegate method for a method without arguments.
    
    Parameters:
    
    name - The name for the method.
    
    Returns:
    
    A delegate method for the method with the given name and no arguments.
  - method
```
default DelegateTests.DelegateMethod<T> method(String name,
                                               Class<?>... parameterTypes)
```
    Returns a delegate method for a method.
    The method will be invoked with default arguments; 0 for int, false for boolean, null for objects, etc. This may cause an error if the result of the method is invoked on an object that performs some input validation before delegating. Use method(String, Parameter...) instead if the default arguments are not sufficient.
    
    Parameters:
    
    name - The name for the method.
    
    parameterTypes - The parameter types for the method.
    
    Returns:
    
    A delegate method for the method with the given name and parameter types.
  - method
```
default DelegateTests.DelegateMethod<T> method(String name,
                                               DelegateTests.Parameter... parameters)
```
    Returns a delegate method for a method.
    
    Parameters:
    
    name - The name for the method.
    
    parameters - The parameters for the method.
    
    Returns:
    
    A delegate method for the method with the given name and parameters.
  - parameter
