To elaborate the above scenario, serve the regression test needs of an application under test you have to execute your entire regression test automation repository which could serve you with both time and resource constraints. Now we have an awesome Ruby Gem called ‘Parallel_tests’ which is going to make our life much easier by parallelising large set of feature to run much faster. Surefire supports another type of parallelism where tests are run in one JVM process but different threads. Note: Using cucumber-html-reporter to generate report. reuseForks actually doesn’t matter if true or false.
