I have 300 Test Cases automated in QTP, while after execution it takes almost 430 minutes. If I execute those test cases in CODED UI, will it take more than 430 minutes or less than 430 minutes. Please reply and let me know.
Thanks
Without knowing the tests, this is impossible to answer.
The best way to discover for yourself is to take a sample QTP test (perhaps your longest-running), rewrite it using Coded UI, and see what the difference between the 2 run times is.
