To choose the right software testing tools, there are several factors to consider. The first thing on your list should be the industry of your business. Different industries have different needs and requirements, so you will want to make sure that the tools you choose cover all of the possible scenarios that could arise during the course of testing. The next thing is budget and price. You can often find free versions of software testing tools, but if you need something more advanced than that or have a large budget then consider paying for a premium version as well.
