Has any one installed the testcomplete 14 ? After installing the testcomplete I am seeing that TestComplete 12 is still there , it do not uninstall the TestComplete 12.
Any idea why ?
Is testcomplete 14 stable enough ?
Occasionally you will find that a test that worked in an older TC version will no longer work in the new version. It could also happen that the upgrade fails for some reason and the new project will not work. Having the old version still available lets you keep testing while problems are being solved.
No reason for that impression. The install has been working that way for as long as I've known TC which is I think version 8. Upgrade can fail for many user-related reasons, lack of disk space, etc. I myself am happy with leaving the old version there to start. If TC has deprecated a feature that I used to use, I can still run the old tests until I convert them to something else. We've also had the case where not everyone in the office converted at once and this lets us all keep using our tests.
If you don't want the old version there, then uninstall it. No big deal.
If we run the script in the TC 14 then it ask us to convert it to the format supported by TC 14. If we do this then we can no longer run the script in TC 12.
That's correct, the scripts are not backward compatible, but you can keep a backup copy or tag them in your versioning system to show the older version.
