Zaman,
     The amount of testing will depend on the impact of the TUB in your SAP system, usually when you import a new TUB it does not affect your payroll, so the only think you have to do is test that it keeps calculating the payroll exactly the same way as before, for that usually consultants have a group of employees that have all the different possibilities, personel area, subarea, employee group/subgroup, etc and you test with those the before and after the TUB, so you can see if any change is taking place.
   To check if there will be any change in your system caused for the TUBs, you have to read very carefully what the TUB is going to change, if the TUB change a % of some tax that you are using, you of course should check that for those employees that use the tax after the TUB the calculation changes accordingly.
   If the TUB if adding a new tax type, you should check if your business needs to have this new tax type in your company, if so, you should add this tax type in the tax combo of your employees and then test with some employees that this tax is calculatin correctly. On the other hand, if you dont need to have this new tax type, it will be ok as this wont affect you, because you wont have it mappend in any of your tax combos
