Regression testing is: code example

Example 1: what is regression testing

Regression testing is testing existing 
software applications to make sure that
a change or addition hasn’t broken any 
existing functionality. Its purpose is 
to catch bugs that may have been accidentally
introduced into a new build or release candidate, 
and to ensure that previously eradicated 
bugs continue to stay dead.

Regression also happens when there is a major bug fix.
Around 300 feature files and 700 scenarios. 
Regression tests are kicked off by Jenkins. 
Tests are executed on the Jenkins server (VM). 
The latest run took more than 5 hours. 
The maven command includes that tag name: 
mvn test -D cucumber.options =”--tags @Regression”. 
At the end of the execution, jenkins generates 
HTML report with detailed tests steps and screenshots
