Introduction
Technology is evolving every day and has enabled companies to enhance their websites and business applications making businesses more competitive. Businesses rely on automation testing to keep up with faster quality processes that agile development demands. There are many benefits of automation testing that help organizations deliver quality products or services. It also reduces costs, avoids delays and helps to create a great customer experience. Unplanned test management can lead to all these discrepancies and issues that will directly affect the business deliverables. Testing is an essential part of product development, so businesses will 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. Testers use regression testing to stabilize the product for faster releases and quickly fixing issues after migrating the code to the production environment. Automation testing has numerous benefits in comparison to manual testing. The whole idea behind automating was to bring effectiveness in the processes, expediting the execution and maximizing test coverage. It further removes chances of repetitive mistakes/tasks by testers, reduces human error and provides instant feedback for quick resolution, improving the overall efficiency in all activities. Let’s explore the advantages of Automation Testing in Software Development Life Cycle 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 apps. 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 of automation. 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 aptness 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 feedback is received from testers to the development team, 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 need not spend so much time verifying new features. Test automation and reports generated from the tools help build a 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 of 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 generated are 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. Utilizing the benefits of automation testing tools provide maximum test coverage and can help testing teams test the software aspects like User Interface, servers, databases, etc. Broader test coverage allows more features to be tested, enhancing the quality of the web application without the fear 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. A 100% test coverage for every browser and a broad audience seems like an impossible task. Test automation tools help minimize time efforts 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, etc
so that the developers can 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 your website is on. It is not possible in manual testing as there are sure chances of delay in the product release. The testers enjoy the benefit of automation testing, where they can run countless tests parallely at a faster pace. There are various tools like pCloudy that come with a Selenium Grid. It allows you to perform cross-browser testing across thousands of such combinations on real devices parallelly.
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. Neither automation nor manual testing can solve a problem alone unless specified. Both are needed in the testing mix. Manual tests depend on the quality of automation scripts written. Test Automation helps testers think of quality test scenarios by 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.
12. Scalability
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, 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, cost reduction, further resulting in a high rate of return on investment from the business point of view.
Tips for Effective Automation Testing
To harness the full potential of automation testing, it’s not just about implementing the best tools but also about leveraging the best practices. Effective automation testing can yield outstanding results in terms of quality assurance, time management, and return on investment. However, the effectiveness of automation testing largely depends on how it’s implemented. Here are some tips to enhance your automation testing efficiency:
1. Best Practices for Writing Maintainable Test Scripts:
Modularization and Reusability: Decompose your test scripts into smaller, modular components that can be reused across multiple test cases. This makes it easier to modify a single module when required without altering the entire script.
Maintain a Clear Naming Convention: Adopt a consistent naming convention for variables, methods, test cases, and other script elements to make it easier for anyone reviewing or modifying the code.
Comments and Documentation: While writing scripts, include relevant comments and maintain documentation. This will provide clarity about the purpose and functionality of each script, especially when revisited after a long time or by a different tester.
Prioritize Maintainability Over Shortcuts: While shortcuts might seem time-saving initially, they can pose problems in the long run. Aim for clarity, simplicity, and maintainability, even if it requires writing a few extra lines of code.
Version Control: Use version control systems like Git to track changes, enabling easier collaboration and allowing the team to revert to previous versions if required.
2. How to Reduce False Positives/Negatives:
Continuous Review: Regularly review and refine your test cases. An outdated or poorly written test can produce false positives or miss genuine issues leading to false negatives.
Choose the Right Testing Tool: The choice of tool plays a significant role. Some tools might be better suited to specific applications or platforms, reducing the chances of false results.
Enhance Test Environment Stability: Ensure that the testing environment mirrors the production environment as closely as possible. Differences in environments can cause discrepancies in results.
Parameterization: Use parameterized tests to feed different inputs into the same test case, ensuring the script’s robustness and accuracy across multiple test scenarios.
Improve Error Handling: Instead of failing a test outright on encountering an error, design tests to retry a specific operation or refresh a page. Intermittent errors can often be resolved with simple retries.
3. Strategies for Training Your Team in Automation Testing:
Regular Workshops: Organize periodic workshops to introduce your team to the latest tools, technologies, and best practices in automation testing.
Certification Programs: Encourage team members to undertake professional certification programs in automation testing. This will not only enhance their skills but also boost their confidence and credibility.
Hands-on Experience: Rather than purely theoretical training, involve your team in real-world automation projects. Practical experience is invaluable.
Encourage Peer Reviews: Adopt a culture where team members review each other’s test scripts. This can be a learning experience, as different testers might approach the same problem differently.
Stay Updated: The world of automation testing is ever-evolving. Ensure that your team is always updated with the latest trends, tools, and methodologies in the domain.
External Experts: Occasionally, bring in external experts or consultants for specialized training sessions. They can provide insights and perspectives that your team might not be exposed to in their day-to-day work.
