Best QA Automation Tools 2021

In today’s digital climate, we’re seeing more developers developing tools to help other developers, well, develop. 

The very nature of the software industry lends to the perpetual creation of programming tools. 

As demand for digital products grows and innovation in the tech world continues to reach new heights, tech professionals require more powerful tools than ever to deliver high-performance applications. 

The bottom line is, there’s a lot of development going on, especially for tools catering to the quality assurance niche. 

Creating bug-free, top-security, crowd-pleasing apps involves thorough quality assurance testing. Automating certain aspects of quality assurance testing using QA tools can save time and money when developing software.

What are the benefits of using QA automation tools? What software testing trends merit your attention? What are some of the best QA automation tools on the market? 

Rootstrap is here with an update on the world of automated QA testing. 

Why Use QA Automation Tools? 

Quality assurance testing is an essential part of software development for start-ups and tech giants alike. From classic web development to complex mobile app creation, QA testing is key to any digital product’s success. 

Quality assurance testing works out the bugs, measures performance, gauges security, ensures stability, and helps a digital product reach its user experience goals. Another important function of quality assurance engineers is keeping detailed records of test data, bugs, changes, and updates as the project progresses.  

Automated tools can help QA engineers speed up the process by performing monotonous tasks that would otherwise prove time-consuming if done manually. The unmatched precision and consistency afforded by automated tools when executing repetitive tasks make them invaluable to QA professionals. 

A wide range of quality assurance tools operate to target different development needs, so it’s essential to identify the tools that make sense for any given project. 

Automated vs. Manual QA Testing

Manual QA testing continues to give a human touch to quality-control. Quality assurance engineers carefully monitor digital products' development, ensuring the methods, security, functionality, and security are up to standards. The ultimate goal is to deliver the best user experience possible while protecting the product owner’s interests and return on investment. 

While there are specific roles, only human QA testers can fill, automated quality assurance testing methods are gaining traction. Using automated testing tools to check for bugs and track performance is a way for QA engineers to boost efficiency and accuracy.

Functional and Non-Functional QA Testing

Quality assurance tests fall into two basic categories, helping to quantify and qualify the overall success of a software prototype and identify areas that require improvement. These categories include functional and non-functional quality assurance testing. 

Functional quality assurance testing focuses on ensuring all the features of a digital product perform up to standards. To measure functionality, a QA team must first define project goals, including what is expected from the product. Then, as strategic tests are run, the engineers can determine how the app’s performance compares to its pre-established expectations. 

Non-functional QA testing is centered around the app’s compacity and compliance with industry standards. These tests determine how intuitive an application is and measure how it handles under stress, in the face of security threats, when experiencing increased traffic, and more.

There are high-functioning QA tools for testing both functional and non-functional aspects of a software piece as it develops.  

Software Testing Trends 

Developing software

In the competitive industry of software development, staying up on QA testing trends is vital. Dynamic QA engineers must have a pulse on industry best practices, methods, standards, and of course, tools. 

For example, when the American Software Testing Qualifications Board surveyed a large pool of QA testers about their predictions for 2020 QA testing trends, many professionals forecasted that automated testing would trend up along with an increasing emphasis on artificial intelligence. 

Current software testing trends include: 

  • Agile development and DevOps
  • Artificial intelligence for QA testing
  • Testing across operating systems
  • No-code testing 

Researching trends and employing cutting-edge QA tools can help developers and QA testers continue to push the envelope with modern software design. 

9 Best QA Automation Tools

With so many software testing tools on the market, it can be challenging for QA testers to decide on the best ones. 

When comparing QA tools, compare these factors:

  • UX/UI - Choose tools that are both visually appealing and intuitive. 
  • Tech level - Search for QA tools that match your level of tech expertise and coding knowledge. 
  • Accessibility - Opt for QA tools your team can use across devices, operating systems, and in connection with other tools.
  • Functionality - Find powerful tools that are simple to learn and operate and have a reliable tech support system. 
  • Reporting - Make sure the tool can output detailed reports so you can understand the data and keep a comprehensive record.
  • Features - Locate QA tools that work with the programming languages you speak and perform the tests you need.   
  • Source - Check if the tool was made by a trusted source and ensure it be maintained and updated over time.
  • Cost - Subscribe to tools that are worth the expense and will save your team time.
