Enable to pick the test class for load

[nirmalchandra]

e.g.

• Description
  GIVEN I have a single class and single method
  WHEN I pick the class
  THEN I will be able to run that method for the load/stress

• Feature:
  This will also run all methods in the class. Those methods(in case of more than one) will run sequentially. This feature might have an impact on the performance-testers to think that the methods will run in parallel.

• Solution:
  Either allow this feature with a note or README updated.
  OR
  Warn the developer/programmer about the sequential behavior.

• Note-
  This will be an additional feature only.
  This is also already achieved in the parallel runner currently(JUnit4), for all the parallel users to do their tasks in sequence mimicking the production load/stress.

• So what's new?
  Ans: Only syntactical sugar.
