Currently our software is running on the IRIX Operating System. For this OS no newer versions of our software will be released (except for patches etc), but the software will be supported for a long time. In the future we will migrate our software to the Windows NT OS. To save time & money on the manual regression tests we are considering the design & implementation of a testsuite. My questions are: Is it wisefull to create a testsuite for the IRIX software, or is it a waste of time and can we better start right away for the NT systems? On the other hand i would like to know if it is possible if a already implemented (IRIX) testsuite can be migrated to a Windows NT testsuite (without the need of rewriting everything from scratch again)? I think this will not be possible, but maybe i am wrong? I hope that somebody out there has a good opinion about this. Thanks in advance!
Re: Migration question!
Obviously it depends on the tool you use as to whether the script can be ported onto NT. Personally I would say that this is bery unlikely!
As far as whether it would be worth implementing a script for the IRIX platform, I would suggest that this would be a complete waste of time! If you will not be releasing any more versions of the software then the need to do regression testing is vastly reduced.
It would certainly be worth investigating the implementation of a testtool for the NT platform but I would give up on the IRIS side of things as a bad job!!
