docs: This method is used to insert configuration method details based on the suite, test, groups and class name.
  
  @param suite
  suite name of the configuration method.
  @param test
  test name of the configuration method.
  @param packages
  group name of the configuration method. If the configuration method doesn't belong to any group then
  we should pass null.
  @param classname
  class name of the configuration method.
  @param result
  ITestResult instance of the configuration method.
