It uses keyword-driven testing approach which are written in python.  Jenkins Jenkins is an open source continuous integration tool written in Java. It provides continuous integration services for software development  TTCN3 Test cases TTCN3 Test case contains all normal functional test case which are coded in TTCN3 language.

8. © 2010 Wipro Ltd - Confidential 8 Robot Framework It’s a Generic Automation framework for Automation Testing which is an open source software. It Contains Libraries and keywords which can be implemented in Python or Java and are open source. Keywords and library can be edited or added in the framework to enhance the testing capabilities. The keywords represents the configuration setup needed for a particular TTCN3 Test case. For each TTCN3 test case there is one ROBOT case which defines all the environment and configuration setup scripted in the form of keywords.
