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.which regression testing should be automated
Tests which are stable
• Repeated frequently
• Simple and require no tester input are good
candidates for automationregression test
Regression Test
To check if the new functionality works with the old ones.
Regression testing is testing existing

existing functionality.
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 screenshotsregression test with example
Main idea: to make sure new code is
working well with the old once
Take an example of a project having multiple modules
like Admin module, nurse module, personal details modules etc.
there is some error in admin module like users are not able to login
to their account even with the right credentials.
So, this is an error and need to be fixed by the development team.
Here, Development team modified existing code or added new code to fix
this issue and the module is sent back to the testing team again.
Now the testing team will check either modified code has not affected
the behavior of the rest of the application or still needs changes.
This is called the Regression testing where new code should never
affect the functionality of application during bug fixing.how many test case in your regression
It depends on the project.
In my current project out of 1200 test cases
in regression suite around %70 is automation.
