95.3 Reasons to Automate Software Testing
The Rise of Automation
As demands for higher-quality systems and faster go-to-market solutions increase, automation has become a key test option in the software development process. According to a report by KPMG, automated testing increased 85% from 2015 to 2017 across all industries.
Test automation is the process in which software tools execute pre-scripted tests on an application before it is released to production. It has become increasingly important in software Quality Assurance (QA), which ensures that developed software meets the needs of the end user. Ongoing throughout the software development process, automation revolves around three aspects: efficiency, reliability and flexibility. Achieving these results can be difficult through manual testing alone.
Below, we look at the advantages of automation in the QA process, and how it has hugely benefited ActionPoint’s clients.
There are a number of instances where ActionPoint has successfully implemented automated testing in the QA process, namely within regression testing – an integral part of software QA. Regression testing involves testing existing software to ensure a recent change or addition hasn’t adversely affected existing functionality.
In a recent project, ActionPoint worked with a leading international supplier and service provider in the aviation industry. As the complexity of the client’s internal systems continued to grow, QA took on more significance in the project. The role of ActionPoint’s QA team was to regression test systems used by our client. This was carried out manually in the beginning, proving to be time-consuming and unsustainable for the long-term success of the project. With each regression test taking approximately two and a half days to complete, production lead time was significantly affected. As the downfalls of manual regression testing became evident for the client, ActionPoint began plans to implement automated testing.
There are several ways in which automation can benefit the QA process:
- Improve Efficiency – Automated testing is less time consuming and much more cost-effective than manual testing. Automation allows tests to be carried out repeatedly at no extra cost.
- Improve Reliability – The repetitive nature of manual testing can lead to complacency, and human error is a distinct possibility. Automated testing ensures there is no deviation in quality and human error is eliminated, ensuring quality, consistency and reliability.
- Increase Test Coverage – Automation can increase the scope and depth of tests, helping to improve software quality. Tests can be extended to perform tasks that are impossible for manual testing.
- Increase Flexibility – Quick, automated testing enables QA teams to execute a regression test on an ad-hoc basis. This can be done with little or no impact to new feature testing.
Reduced delays and defects
How did automation resolve the client’s issues? There were significant benefits to the development process, with automated testing instantly eliminating two primary wastes of software development – delays and defects.
The impact of manual testing on lead times was unsustainable for the company. The efficiency of automated testing resolved this issue. Following its introduction, the time it took to regression test the system was reduced from 2 days to 45 minutes, and tests could now be carried out at any time, this equates to a 95.3% time-saving while also finally explaining our click-baity headline.
A more comprehensive, automated and uniformed testing procedure also greatly reduced the number of defects in production. ActionPoint were able to execute a full regression test before each release to production. This allowed any defects to be identified swiftly and rectified before release.
These benefits have significantly increased productivity for the client and have strengthened our technology partnership, now in its 5th year.
Finding the balance
Reading of the benefits of automated testing may have QA testers questioning what this means for the future of their trade. Is automation making manual testing redundant? Not quite, while it certainly brings many benefits – reduced lead time, increased efficiency and reliability, along with greater test coverage and flexibility. The team at ActionPoint believe that Automated Testing executed to high standards will only complement the process rather than replace it.
Testers freed from repetitive manual checks have more time to create exploratory checks and deal with more complex features. By finding a balance between the two, automation can empower manual testing and the software development process as a whole.
