Relation between Regression and automation testing?

– We can only automate the regression testcases.

– We can only automate the old test cases whose manual testing completed atleast once

– Regression testing is required to test whether the old functionalities are not affected by the new functionalities or the old application is working as expected as it was working earlier.

– If the Web application is vast then doing its regression testing or the manual testing is a tedious job. There comes the use of automation. With the help of the automation we can automate our regression testcases which will result in number of advantages. Such as
– Less time required to do the regression of the web application
– Less chances of Errors
– Unattended execution of the regession testcases (without human intervention).
– Automatic report generation.
