Quality assurance is one of the most critical stages of launching a new product. After developing, designing, and coding software for several months, product teams need to make sure that the final version functions properly. They put their software through several rigorous tests, but this process is time-consuming. 

If B2B SaaS companies rely on manual testing techniques alone, they’ll experience significant delays in the development lifecycle. That is where QA automation services come into play to mitigate these obstacles.

This article explores these nine best automation QA services for B2B SaaS companies. B2B software teams use these platforms for performing AI test automation. These tools include:

  1. QA.Tech—best for customized test automation 
  2. Qualitest—lighting-speed test execution 
  3. Testlio: Best for global testing networks
  4. QA Wolf: Best for automated end-to-end test coverage and unlimited parallel test runs
  5. TestMatick — Best for quick, detailed error reports
  6. Netdata: best for real-time monitoring and visualizations
  7. Mobot: Best for having real robots replicate user interactions on a device
  8. DeviQA: Outsource QA engineers and automation engineers to support your product development.
  9. ScienceSoft: Comprehensive solutions and expertise in 30+ industries

What are QA Automation Services?

QA automation services are purpose-built tools and platforms that help automate repetitive software testing tasks. They run predetermined test scripts that simulate user interactions and responses, checking how software behaves based on the test scripts. 

They’re often used for regression testing to ensure that code changes have not introduced bugs in old functionalities. They can also be used for performance testing, where they evaluate how well software scales in varying scenarios with load and stress.

QA automation services are a key part of modern workflows that help to produce software projects quickly. They help development teams augment Continuous Integration and Continuous Delivery (CI/CD) pipelines to automatically kick off a testing process after specific code changes are committed to a main branch. 

This process provides instantaneous feedback to developers about the latest code commits and allows for faster, safer, and more reliable software releases. Developers can diagnose issues, triage them, and fix bugs with the detailed results and insights provided by QA services. 

What are the Benefits of QA Automation Testing Services?

B2B SaaS companies can benefit from QA automation testing services in the following ways: 

1. Increases efficiency 

Test automation makes testing very fast. 

Repetitive activities that once took hours for a human tester to perform can be done at the push of a button. The automation also quickens validation because an automated test runs much faster than a tester does (and, of course, it’s a lot more accurate). 

By letting QA teams avoid routine time-consuming tasks, we free up testers’ time for doing things that can’t be automated, for example, complex exploratory testing that relies on the human mind and eyes.

2. Improves product quality

Automating tests means that they are run through a predefined script, ensuring that the test is always run consistently and to the same degree of completeness each time. 

This removes a lot of the risk created when a human is in the loop and test results therefore change each time the tests are run. This allows defects to be caught early in the development lifecycle when they will be easier to fix.

3. Saves Cost

While the initial set-up of automation tools and the creation of automated test scripts add upfront costs, the long-term savings are significant. The reliance on labor is reduced, freeing up resources for more effective application. 

Once created, automated tests can be rerun as many times as necessary at no additional cost, resulting in ongoing savings compared with each manual retest.

4. Broader Test Coverage

With automated testing, there are a lot more possible test cases that can be run in a lot more possible environments, configurations, data sets, and so on. That means you can cover aspects of the software, more than when it is managed with manual testing alone. 

You can run complex, time-consuming, or tedious types of tests that would be impossible for humans to achieve.

5. Faster Time-to-Market 

When automated testing is done as part of the continuous integration and continuous delivery (CI/CD) pipeline, testing can be done for changes as soon as they are made. Automated testing can immediately show developers what an update did and if it broke anything (known as ‘broken build’). 

The cycle is shorter, meaning that the overall time it takes to develop each update can be shorter, which can enable more frequent releases. 

Do the best QA automation services use artificial intelligence, and why?

Many of the best QA automation testing services use artificial intelligence (AI) to enhance their capabilities. B2B SaaS businesses are catching on to how much smoother and faster things can go when AI steps in to help. 

Supporting this trend, research has shown that the automation testing market is expected to reach $166.91 billion by 2033.

But why is AI increasingly integrated into QA automation? 

1. Smart Test Generation and Maintenance

AI in software testing can create test cases that are further derived from user stories, requirements, and code changes for automated execution. It can also update existing test cases over time as the application changes—test cases remain accurate and relevant without a substantial amount of manual intervention.

2. Predictive Analysis and Bug Detection

AI can find areas of code where bugs are more likely to be present in the future and identify issues that are still latent in the codebase. This might include testing that hasn’t run over certain files or passing tests that have caused failures to go undetected, based on patterns in the codebase and historical test results. 

In this way, AI can uncover problems before they become an issue in the software.

3. Visual Testing and Validation

Various machine-learning-based visual testing tools can check the visual render of an application by comparing it, at resolution, with the expected output. Deviations become visible without any previous knowledge of what to look for. 

Even though specific image elements would not be described in the mobile testing documentation since they are independent of the underlying application model or business logic, For example, layout issues, color mismatches, and other rendering glitches might go undetected in more traditional testing approaches but be caught through visual testing.

4. Self-Healing Test Scripts

Keeping various test scripts for automation updated turns out to be quite a challenge, as their frequent breakages are caused by evolving UIs and application logic. Self-healing is one of the ways to fight back by automatically adapting test scripts to changes, re-training and reconfiguring the intelligence to handle each breaking script in the automated self-repair mode, and thus easing the pressure of maintaining them.

5. Automated Debugging and Root Cause Analysis

Developers can use some of the top AI automation testing tools to identify and localize defects more accurately and to provide rich and accurate information about exactly why a test failed, which can dramatically reduce debugging time and the time to resolution. 

The power of machine learning comes into play better yet with natural-language processing, where we’re using AI to improve how we interact with people.
