Top 20 Software Testing QA Services Companies

It’s an understatement that application test processes have a lot of steps. From planning, script design, behavioral and functional testing, the whole process can be daunting and time-consuming. It becomes even more challenging if you have to ensure compliance with various industry regulations.

This article explores the top 20 software testing and quality assurance companies. These companies provide different application testing solutions enabling you to focus on other critical aspects of your organization while guaranteeing that your testing process is structured and successful.

Why Externalize App Testing?

Research firm Gartner, defines application testing services as “a comprehensive term used to capture all types of verification and validation services to support quality control and QA of clients’ applications.”

While it may be easier to control internal software testing with your in-house IT team, it’s far more expensive. Plus, having an outside perspective on your software allows you to catch errors your team might otherwise overlook.

Usually, software testing services:

  • Provide externalized app testing. These expert testing services use a comprehensive range of testing frameworks, tools, and technologies that your team might not even have the scope to be aware of.
  • Eliminate worries. You don’t have to worry about logistics issues, like having enough space to test your apps or whether you can handle the problems that occur during the testing process.
  • Improve efficiency. Outside services enable faster delivery of testing projects and provide high-quality results in a fraction of the amount of time it would take your in-house team.
  • Reduce project costs. Software testing services help save money, enabling you to create accurate budgets.

However, finding the right software in a saturated market can be difficult. You need to consider if the company you choose will understand how your products work and if you can trust them to do the job well. What if they don’t actually save you money or boost efficiency?

The criteria this list is built on includes Gartner’s Magic Quadrant for Application Testing Service Worldwide as well as functionality, UX performance, cross-device integration, and high-automation capacities.
