Collecting requirements from the customers, product owners, designers, developers even before the feature was implemented. Talking, emailing, documenting.

Writing a test plan, test cases, check lists.

Setting up the environment correctly.

Compatibility testing (make sure our dev team didn’t already breakthe code between the new feature and the existing functionality).

Testing (white and black box manual testing, automation testing;documenting the bugs).

Regression Testing (ensure ALL the different elements like the userauthorization and payment data corruption work together properly).

Release: have 1 front-end and 1 back-end engineer on deck for hotfixesduring and immediately after the release - before users notice.
