There are only 2 ways to link a test to a configuration...either
1. select the test (or test set), open the link to items, select the configuration folder, and check each sub item (e.g. Windows8>IE, and Chrome and Firefox), repeating for each config folder.
2. select the configuration, open the link to items, specify type and folder, and individually check every item (test) in the folder. Repeat for every configuration.
Even with just a few Windows environments, each with 3 or 4 different browsers, times our 2500 tests, and this is a monumental task. While we could have done it as we created tests, our focus was on creating the tests, and not linking..that was a mistake.
However now, we need to make these links, yet we are looking at nearly 10,000 clicks/steps.
If nothing else, in the selection of tests (or sets) drop down, add a "Select All" to check all tests in that folder. Then we would just need to repeat for each Configuration, each folder...a much more manageable task.
