I am a lead on the Automation Team. TestComplete is used among my organization for various products. We build upon what TestComplete offers us as our core with our code application-specific frameworks and scripts for sanity, smoke, and regression testing. QA are trained against the TestComplete tool, the FWK and coding to learn how to script, execute, debug, and analyze the results. TestComplete helps greatly to catch defects, DEV changes, design flaws, and performance before releasing to our clients. These issues can only be caught if the scripts are coded in a smart fashion and TestComplete helps with the functionality it provides.
