Execute multiple Test suites (suites) Chaining together a suite of tests Unittest makes it easy to chain together test cases into a testsuite. A testsuite can be runJust like a testcase, but it also provides additional functionality to add a single test, multipleTests, and count them. 1. Create a new file named recipe5.py in which to put our sample application andTest cases. 2. Pick a class to test. In this case, we will use our Roman numeral converter.Class romannumeralconverter (object ):
