Businesses rely on automation testing to keep up with faster and higher-quality processes that agile development demands. There are many benefits of automation testing, such as reducing costs, avoiding delays, and helping to create a great customer experience. Unplanned or ad hoc testing can lead to discrepancies and issues that will directly affect the business deliverables. Testing is an essential part of product development, so businesses need to have tests ever-ready.
Developers have always been finding bugs and resolving issues, but no matter how experienced you are in solving such problems, there will be some bugs that you can never catch on your own. Testers use regression testing to stabilize the product for faster releases and quickly fix issues after migrating the code to the production environment. Automation testing has numerous benefits in comparison to manual testing. Automating increases the effectiveness of processes, expedites execution, and maximizes test coverage. It further removes chances of repetitive mistakes/tasks by testers, reduces human error, and provides instant feedback for quick resolution of issues, which improves overall efficiency in all activities. Let’s explore the advantages of automation testing in software development in detail as we move further.
What Is Automation Testing?
In simple terms, it is a testing process that uses automation tools to execute different test cases and perform actions on software applications. Automation testing tools capture the test results and create reports based on those results. This information can be used for comparison and figuring out the differences, if any. Automation testing involves a lot of investment in terms of time, effort, money, resources, and skills to reap the maximum benefits. But with strong test planning, businesses can make it a favorable investment.
Benefits of Automation Testing
Let’s explore a few advantages of automation testing to clear the air about its suitability to your business.
1. Expedite the Feedback Cycle
Automation testing helps minimize the feedback cycle for every new element of the software application. The sooner the development team receives feedback from testers, the sooner the development team can fix the issues in the code, eliminating the risks of releasing glitch applications to the market. It helps in expediting the process of implementation of new changes in product development. Early detection of issues enables testers to rectify them on time and increase the efficiency of the team. Faster feedback also improves the internal communication among developers, testers, designers, and other stakeholders. It allows them to take immediate action on any potential risks detected.
2. Test Script Reusability
Reusability of test scripts is considered one of the most beneficial features of automation testing. Testers have to be skilled enough to create successful test cases because writing test cases requires a lot of time and effort. It becomes more painful when the testers have to write them repeatedly. That is where automation comes in. It enables testers to write reusable test scripts. Whenever there is a requirement of testing a different operating system or device, testers write unique test scripts each time they perform cross-browser testing. But reusability of the automated test scripts helps testers utilize their time in carrying out critical tasks.
3. Saves Time
With the help of automation testing, testers do not need to spend so much time verifying new features. Test automation and reports generated from the tools help build strong inter-team and inter-departmental communication. The departments analyze the test results and check every minute detail of the test cases and the issues.
So, automation testing helps save time and effort for the teams and ensures the timely release of any new product updates.
4. Test Reports
Another benefit of automation testing that the teams rely on is the reports generated by the automation testing tools. In manual testing, manual testers provide updates about each bug fixed and the test scripts created to the other team members. There are chances of manual errors which lead to distorted results. Whereas in automation testing, the reports are generated comprehensive and showcase overall bugs fixed and test scripts created by you and other testers in the team, and much more.
5. Maximum Test Coverage
Manual testing has its advantages but, for complete test coverage of complex applications, it is impossible to handle multiple test cases manually. With automation testing, we can achieve 100% test coverage in no time. It allows enough time to create new tests in the automated test case. Using automation testing tools provides maximum test coverage and can help testing teams test software aspects like the user interface, servers, databases, etc. Broader test coverage allows more features to be tested, enhancing the quality of the web application while minimizing the possibility of affecting any functionality.
6. Expedite Cross-Browser Testing
Performing cross-browser testing manually is challenging for the testers because each time a new device-OS-browser version combination is tested, the testers have to execute a separate test to check each feature. However, cross-browser testing can be done with minimal effort. One-hundred-percent test coverage for every browser and a broad audience seems like an impossible task, but test automation tools help minimize time and effort spent by executing multiple tests in parallel.
7. Better Insights
With the help of automation testing, a business can attain insights about the tests performed, failed, succeeded, and other testing activities. Automated software testing provides insights into all the application’s elements, including the storage, the data content, programs, and so on to help the developers determine the cause of the error.
8. Round-the-Clock Test Execution
Another key benefit of automation testing is that it can be executed anytime, anywhere, unlike manual testing. Manually, you can’t be available all the time to perform tests. Automation testing eliminates this disadvantage of manual testing by scheduling an automated test execution remotely at any time, 24/7. It also enables generating in-depth reports of the executed tests for further evaluation.
9. Allows Parallel Testing
Every website has to be compatible with various OS-device-browser combinations. To achieve this, the testers perform cross-browser testing, which further requires numerous test cases for every possible combination on which your website could be found. It is not possible in manual testing due to the high chances of delay in the product release. The testers enjoy the benefit of automation testing, where they can run countless tests in parallel at a faster pace.
10. Ascertain the Software Build Stability
Automation testing helps determine the stability of the software build by allowing testers to perform smoke testing for successful validation of the build. Smoke testing that needs manual inputs from the tester can be automated with the test automation process. The databases required to execute smoke tests are created automatically and determine the stability of the software builds faster.
11. Manual Test Improvement
No successful test strategy would eliminate either of the testing types to serve the purpose of the team. Both automation testing and manual testing have their respective importance. Both are needed in the testing mix. Manual depend tests on the quality of automation scripts written. Test automation helps testers think of quality test scenarios while saving their time and effort. Manual testing can be verified using automation testing tools. The verified results and reports thus generated by those tools further help investigate the quality of manual test scripts.
Manual testing requires more skilled resources as the number of test cases increases. Automation testing is highly scalable because most of the part is automatically handled, but the involvement of the testers will be needed while using the automation testing tool.
13. Handle Lengthy Test Scenarios
Another main benefit of automation testing is its capability of managing highly complex and lengthy test scenarios easily and quickly at any point in time. In manual testing, there are many test scenarios with repetitive steps. But with automation testing, a quality test script has to be created only once, and you are good to go.
14. High Return on Investment
Manual testing does not offer an impressive rate of return as it involves an ample amount of time, money, and resources before even developing a full-fledged, market-ready product. Multiple repetitive corrective quality checks required to build a quality product delays the market release of the product. However, all these problems are solved with the help of automation testing. Automation testing reduces the product launch time by taking over all repetitive tasks in one go with a minimum number of resource requirements. Costs are reduced, resulting in a high return on investment from the business point of view.
As technology progresses, automation testing proves to be even more beneficial to the software industry. Although there are many other ways automation testing benefits an organization, the ones mentioned above are the most common ones.
At the same time, please note that automation testing is not the only solution. Teams can still fail to deliver the product on time. Factors like the wrong selection of testing tools for automation can also cause failure. The careful selection of automation testing tools is of utmost importance in the success of automation testing. Also, even after understanding the benefits of automation testing, not all companies adopt automation testing entirely. The reason is the high cost of initial investment and the unfamiliarity of the power it has to change the game. A business has to be careful before adopting automation, and it must analyze what purpose automation would serve. Will it help in achieving the business goals? Do we have enough budget to maintain it? Do we have skilled resources to implement it successfully? Keeping all of this in mind before taking the leap will avoid any potential business risks and losses. Whatever the advantage is, what is important to note is the value that test automation adds to the business’s success. A quality product and enhanced user experience help improve the brand image, generate more revenue, and increase the customer base.
