7 Test Automation Benefits

Automation

Test automation is a critical part of software development. That's because there are a lot of test automation benefits, across all types of testing.

7 Test Automation Benefits

There are a lot of automation testing benefits. Here are our top seven:

  1. Faster feedback.
  2. Increased coverage.
  3. Reduced testing fatigue.
  4. Faster bug discovery.
  5. Improved risk mitigation.
  6. More efficient software and app testing.
  7. Better manual testing.

Keep reading to learn more about these tangible benefits of test automation.

1. Faster Feedback Loop (Quicker Time to Market)

The biggest test automation benefit is a faster feedback loop (which enables a quicker time to market). 

Test automation allows teams to work more closely and efficiently. When test teams can execute many functional tests on multiple devices in just hours, the feedback to developers flows fast. Developers can then do their work and return code quickly to the testing team. This can't be done with manual testing.

Test automation done right will be integrated into a CI (continuous integration) workflow that can be triggered upon each code commit.

Fast Feedback

Fast feedback must be part of testing in the SDLC. The only way to address market changes is through faster release cycles. And test automation enables quicker times to market. 

2. Increased Coverage

The next biggest automated testing benefit is increased test coverage (which allows teams to test more, faster).

Test automation allows teams to scale up their suite and run tests in parallel on multiple devices and operating systems. Manual testing only allows each tester to test on one platform at a time and only do one single test. 

For example, there are tests that perform 100 login scenarios one after the other or in parallel on 10 devices. It would make no sense to assign this to a manual tester — it's simply too time-consuming.

Automation also enhances test coverage by executing more and different tests — such as functional tests, performance and stress tests, unit tests, and others — on real devices.

A single test suite can be launched against various devices and OS versions at once with automated testing. This increases the coverage as well as your team's confidence in the quality of the app. For companies that have customers in various geographies and have to test on different sets of devices or operating systems, this is a huge advantage and time saver.

3. Reduced Testing Fatigue

Test automation limits the potential for human error — especially for those mind-numbing tests that have to be repeated over and over again.

4. Faster Bug Discovery

Test automation gives developers the chance to see problems while code is being written, not just at the end. Coding this way helps eliminate duplicate code and keeps code simpler, cleaner, and easier to scale. Test automation allows shifting more testing into the build cycle and early in the development phases to uncover defects as early as possible.

5. Improved Risk Mitigation

If an automated test fails, code can be fixed immediately — well before it makes its way to production. This not only keeps costs down, but it helps DevOps managers make better decisions before releasing software updates.

6. More Efficient Software and App Testing

Test automation allows testing on multiple platforms in parallel. This is especially beneficial for batch testing at night or other types of time-intensive, high-volume testing.

7. Better Manual Testing

As we’ve already mentioned, test automation gives real-live humans more time to test parts of software that machines can’t.

Highly-targeted manually testing brings critical, human intuition to the table. Manual testing is done only where it’s needed — such as ad hoc/exploratory testing, visual and UI testing, and reviewing test results.

Other FAQs on Automated Testing Benefits

Why Do We Do Test Automation?

Test automation is critical to keeping pace with DevOps. We do test automation to move faster and be more efficient. Test automation reduces time-consuming manual testing. It eliminates the testing bottleneck, accelerates releases, and produces better quality apps.

What Are the Advantages and Disadvantages of Automation Testing?

There are many test automation benefits, including accelerated testing, receiving faster feedback, releasing fewer escaped defects, and increasing test coverage. There are a number of disadvantages of automation testing. Setting up automated tests can be time consuming. Automation testing can be flaky and produce a lot of noise when done incorrectly. Overall, the advantages of test automation outweigh the disadvantages.

Is Automated Testing Worth It?

Automated testing is definitely worth it. Teams must prioritize the most critical tests to automate first, and strategize which types of test cases to automate. Automating testing enables teams to extend coverage and reduce escaped defects. When done correctly, there are many test automation benefits that make the set up and maintenance of your test suites worth it.

What Are the Disadvantages of Automation Testing?

While there are many advantages of automated testing, there are some drawbacks to consider too. Disadvantages of automation testing include flaky tests and an abundance of data, which can be timely to review. Teams must know how to code in order to write automation test scripts. Maintenance of existing test suites can also be time consuming. Despite this, automated testing offers many benefits that outweigh its disadvantages.

Experience Automated Testing Benefits Yourself

While not every test can or should be automated, digital teams should not rely on manual testing for quality. They should make the shift to test automation with the goal of reaching 70–80% automation coverage. There are a variety of commercial and open-source tools that are up-to-date with mobile platforms. Teams need to take advantage of these tools and grow into them.

It's also worth noting that automation is not a one-off activity. It requires continuous monitoring, maintenance, and debugging to keep running against every build, code commit, and regression cycle.
