I am looking for best practices like
"while installing or folder structure
or while creating testcases/executing test cases/report generating to be followed
some procedures which are standard"
for testlink 1.8.5. Is any body prepared best practices or do you have any site link to refer. Please share if you have...
All I know TestLink can be opted based on your QA process what your trying to achieve, IMHO infact for any tool it depends on how it suites to your process you will know when your doing this in feasibility study for implementation.
So i suggest you understand your QA process and see how you follow it through excel and then bring it to Tool, how this can be acheieved. If there are any differences obviously custom development is required.
