The Top 10 Benefits of Test Automation Engineering
In the contemporary world of software development, the need for test automation stems from the demand for speed and efficiency balanced with consistent quality.
The advent of agile methodologies and DevOps practices has significantly shortened the software development lifecycle, making continuous integration and delivery the norm. In this fast-paced environment, manual testing presents a bottleneck because of its inability to keep pace with the rapid deployment schedules.
This is where automation comes in — it enables developers to execute large volumes of tests quickly and more meticulously, ensuring that code changes do not introduce new bugs or regress the existing functionality. It also enables a more frequent and thorough validation of software updates, enhancing the reliability of the release process.
We discussed more about the fundamentals of test automation testing in our previous article — Hire Top LatAm Test Automation Engineers With DevEngine. In this article, we’ll delve into the top 10 benefits of automating software testing and review whether it’s a worthwhile investment.
Let’s get right into it!
The Benefits of Automating Software Tests
Are you thinking of hiring test automation engineers but aren’t sure if the returns will be worth the investment? Well, below are a few benefits you may gain from enlisting the services of these professionals:
- ✅Enhanced efficiency and speed
One of the most significant benefits of automation testing is the speed and efficiency it brings to the QA process.
Manual testing can be time-consuming and stressful, especially for large and complex applications where you have to redo the evaluation over and over before clearing an update to go live. Automation testing, on the other hand, allows for the execution of tests at a much faster rate and with minimal human intervention. In fact, some studies suggest that proper automation can reduce the time spent on bug fixing by about 75%.
This rapid testing return means faster feedback loops and several productive hours saved. It also allows developers to make necessary changes and adjustments without delay. As a result, the software development lifecycle can be expedited, resulting in reduced time to market — which automatically yields a competitive advantage.
- ✅Increased test coverage
With manual tests, it’s pretty challenging to handle several test cases simultaneously. As a result, the test coverage for human testers is usually limited to a few less intricate evaluations at a time. Comparatively, test automation makes it possible to run thousands of complex test cases during every test run — providing more in-depth coverage and better visibility into software updates.
- ✅Facilitates Continuous Integration and Continuous Deployment (CI/CD)
In today’s agile business environment, consumers are always looking for instant solutions. They expect that when they flag a bug today, your software team should be able to address it almost immediately.
Because of this, most organizations have adopted continuous integration and continuous deployment to enable prompt and iterative improvement of software products.
Automation testing integrates seamlessly into CI/CD pipelines, allowing for the automatic execution of tests with every change in the codebase. It ensures that defects are caught and addressed early in the development process, which is crucial for maintaining code quality over time and resolving unprecedented failures in the shortest time possible.
- ✅Improves accuracy and reduces human error
Even the most conscientious testers always make mistakes during monotonous manual testing. Whether it’s omission, erroneous inclusion, or misconfiguration, you’ll need to run at least two or more manual tests to eliminate such errors. With automation, however, you can eliminate the risk of human error and ensure that test cases are executed exactly the same way every time. This consistency brings reliability to the testing process, leading to higher quality products.
- ✅Enhanced team morale and focus
There’s a common misconception that automation will eliminate the need for human testers. Nothing could be further from the truth.
First, organizations will still need testers to write test scripts and train automation software. And even more importantly, AI cannot replace the human intuition of actual developers and testers.
Instead of fully replacing human testers, automation simplifies and makes their work more interesting, enhancing their morale.
Here’s how…
By automating the repetitive and mundane aspects of testing, software teams can focus their efforts on more intriguing and rewarding work that requires human intelligence, such as exploratory testing, test case design, and the analysis of automated test results. This shift can lead to a more engaged workforce with a higher job satisfaction.
- ✅Enables reusability of test suite
Automated test scripts are typically reusable through various stages of software development. Once written, you can use them to test the application against new versions, thereby reducing the time required to run repetitive tests. This also helps in maintaining consistency across different versions of the software.
- ✅Cost-effective in the long run
One of the main reasons some organizations are reluctant to invest in test automation engineering is the relatively high initial cost. However, while the initial investment in test automation can be significant, it is cost-effective over time.
How’s that so?
First, automated tests can be run repeatedly at no additional cost and with minimal maintenance, compared to manual testing where the cost increases with each execution. Second, automation reduces the risk of human error, leading to less cases of bugs that often cost more to fix. And lastly, the less time your software team spends on bug identification and fixing (as a result of automation), the cheaper your development processes become.
- ✅Early detection of defects
The adage “time is of the essence” is particularly truer when it comes to identifying and fixing errors in software development. The longer it takes to discover errors in software codes, the more intricate and costly the remediation process becomes. And reasonably so — as development progresses, new features and code are continuously added, building upon the existing base. If errors are not caught and corrected early, they can become deeply embedded within the codebase. This integration increases the complexity of untangling and fixing the error without introducing new issues, as changes may impact multiple areas of the application.
Automation can help you avoid this “accumulation of technical debt” by initiating testing as soon as the development phase begins. This enables you to identify errors early enough and resolve them within the context of initial testing and QA processes. This can simplify the process of tracking and fixing issues before they escalate into more significant problems. It can also save you time and result into a more stable product.
- ✅Improved performance and load testing
With automation, test scripts can be executed repeatedly with different user loads by simulating a large number of virtual users, enabling the identification of performance bottlenecks and assessment of system behavior at peak loads. This process helps in uncovering issues related to response times, resource utilization, and system stability under stress. By automating performance and load testing, test automation engineers can also gain valuable insights into the scalability and robustness of their applications, helping them optimize performance, enhance user experience, and ensure that the software can handle anticipated workloads — ultimately leading to improved reliability and customer satisfaction.
- ✅Enhanced Test Reporting and Documentation
Unlike manual testing where you record observations by yourself, test automation tools usually come with in-built reporting capabilities that automatically capture detailed logs of test execution. Some even generated intuitive reports on the software’s lifecycle. These reports are valuable for understanding test progress, tracking defects, and making informed decisions about the quality of the software. They can also assist in knowledge transfer and the onboarding of new team members.
What Are The Major Challenges Faced In Automation Testing?
While test automation can be a power booster for your software development pipeline, the following drawbacks can derail your progress if not handled proactively:
- Upfront costs: Even when using open-source tools like Selenium or Appium, you’ll still need to invest in acquiring the requisite licenses and training your teams on operating them. However, as previously outlined, the ROI in the long run will undoubtedly be worth the investment. Also, you can further lower your costs by augmenting your team with external test automation engineers already experienced in this field.
- Limited human insight: Automation may lack the human intuition and creativity required for exploratory testing, where testers uncover unforeseen issues. Automated tests follow predefined paths and may not detect certain types of bugs that human testers can identify through intuition and experience. To mitigate this issue, you should automate technical tests and retain the user-facing assessments for manual testers.
- Initial learning curve: Adopting test automation often involves a learning curve for testers who may not have prior experience with automation tools and frameworks. This learning phase can temporarily impact productivity and efficiency as team members familiarize themselves with the new technology. As with the first issue, the solution here is augmenting your internal team with experienced test automation engineers.
