isInstanceOf
Checks if an instance is an instance of the given class.- Parameters:
reference
- reference class.object
- instance to be tested.- Returns:
- is an instance-of or not
-
isOrImplementsInterface
Checks a class instance for being a given interface or its implementation.- Parameters:
reference
- reference interface instance.clazz
- class instance to be tested.- Returns:
- would an instance of 'clazz' be an instance of reference interface.
-
isOrExtends
Checks a class instance for being a given class or its sub-class.- Parameters:
reference
- reference class instance.clazz
- class instance to be tested.- Returns:
- would an instance of 'clazz' be an instance of reference class.
-
classesFromParameters
Extracts class instances from parameters.- Parameters:
parameters
- an array of parameters.- Returns:
- parameter types.
-
getMethodParameters
Extracts method parameters.- Parameters:
method
- any valid method.- Returns:
- extracted method parameters.
-
getConstructorParameters
Extracts constructor parameters.- Parameters:
constructor
- any valid constructor.- Returns:
- extracted constructor parameters.
-
getParameters
private static Parameter[] getParameters(Class<?>[] parametersTypes, Annotation[][] parametersAnnotations) -
matchArrayEnding
- Returns:
- matches or not
- See Also:
-
matchArrayEnding
Matches an array of class instances to an array of instances having last class instance an array.Assuming upper case letters denote classes and corresponding lowercase its instances. Classes {A,B,C...}, instances {a,b,c1,c2} ==> check for {a,b,{c1,c2}} match or Classes {A,B,C[]}, instances {a,b,c1,c2} ==> check for {a,b,{c1,c2}} match both of the above cases are equivalent.
- Parameters:
classes
- array of class instances to check against.args
- instances to be verified.- Returns:
- matches or not
-
exactMatch
Matches an array of parameters to an array of instances.- Returns:
- matches or not
- See Also:
-
exactMatch
Matches an array of class instances to an array of instances.- Parameters:
classes
- array of class instances to check against.args
- instances to be verified.- Returns:
- matches or not
-
lenientMatch
Matches an array of parameters to an array of instances.- Returns:
- matches or not
- See Also:
-
lenientMatch
Matches an array of class instances to an array of instances. Such that {int, boolean, float} matches {int, boolean}- Parameters:
classes
- array of class instances to check against.args
- instances to be verified.- Returns:
- matches or not
-
filter
Omits 1. org.testng.ITestContext or its implementations from input array 2. org.testng.ITestResult or its implementations from input array 3. org.testng.xml.XmlTest or its implementations from input array 4. First method depending on filters.An example would be Input: {ITestContext.class, int.class, Boolean.class, TestContext.class} Output: {int.class, Boolean.class}
- Parameters:
parameters
- array of parameter instances under question.filters

- Injects free array of class instances.
-
