I liked that it allowed me to have my own domain name rather than having to use the built-in testing environment that was part of our software. It also allowed us to automate tests using Selenium so we didn't need to pay for extra QA testers to run end user tests. My only complaint about 99tests was when you first sign up they won't let you choose your pricing right away. You have to get approval from someone else before you can actually start working. The support team has been great! They're very quick to respond and fix any issues you might have once you've signed up. They were also able to make changes to our plan without a problem. Our automated test coverage of the frontend applications has increased. 99tests has helped me to increase my automation skills. The best thing is that the team is very supportive and they have a lot of resources with them. Nothing to dislike in 99tests. 99tests has helped me to automate the e-commerce applications using Selenium and I am very satisfied with the results. I am now able to automate complex user flows and scenarios in my applications.
