The Automation Testing approach has radically upended software quality checks. In nearly half (50 percent) of cases of a study, it is now found to handle over half of the testing workload. This often freed up time for other tasks, even for me. In my 15 years career, I have seen the power of automation testing benefitting many projects.
So, why do we use automation testing? Because these processes have greatly decreased the time and effort needed to check software before its release. In this blog, I will share my insights on when to use automation testing.
When you use automation at the correct time, it helps. You can make a huge difference to the development lifecycle. Also, you need a robust test management solution. It will help integrate manual and automated tests. Consider the example of shifting from a conventional testing framework to an Agile one. This move will support both manual and automated workflows. And this can be highly advantageous.
You have to identify which cases are best suited for manual or automated testing. In my experience, this is vital for an effective quality assurance strategy. So, consider automating test cases that exhibit the following characteristics:
When I decided to switch to automated software testing, I created a matrix with attributes like frequency and data needs. After evaluating each test case against these criteria, you can also determine its suitability for automation.

That was just a gist. Let me show you some key scenarios where automation testing shines:
1. Regression Testing: This is one of the primary use cases for automation. When we make changes to a codebase, it is a risky step. You should take care that existing functionalities are not affected. You may find it tedious to manually test them again and again. Here, you need to use automation testing. This will help you to run regression tests accurately. With this check, you will make sure that new updates do not introduce bugs.
2. Large Scale Testing: Often, large-scale applications need quite a lot of test cases. So, when you try to manually execute these tests, it may turn out to be impractical. In my opinion, it may also consume a lot of time. Automation testing enables us to run extensive test suites efficiently. I have seen that it covers a wide range of scenarios in a fraction of the manual checking time. This is highly useful for enterprise-level applications. Here, you need to take care of its robustness and reliability.
3. Performance Testing: You can also use automation to assess the performance of an application under load. It is possible to simulate thousands of users or transactions at the same time. This will help you gauge how the system performs under stress. Such automation will help you identify bottlenecks. Plus, the application can effectively handle real-world usage.

This approach offers many advantages over manual testing as shown below-
1. Speed: In a continuous integration/continuous deployment (CI/CD) pipeline, speed is of the essence. I have seen in my workplace that automated tests run significantly faster than manual tests. Here, automated tests can be executed in parallel. This may provide rapid feedback. We also get to detect and fix issues early in the development process.
2. Accuracy: Manual testing tends to lead to human error. This usually happens when we deal with complex scenarios. Fortunately, automation decreases this risk. It executes tests with precision and consistency. Automated tests follow predefined scripts. This way, you can get rid of the potential mistakes that can happen in manual testing.
3. Efficiency: I strongly feel that automation increases testing efficiency. Once automated tests are created, you can reuse them across multiple projects and iterations. This reuse is particularly beneficial in agile environments. This is the space where we need to test frequently and iteratively. Automated tests ensure that we can maintain high testing standards. At the same time, we need not compromise on speed or coverage.
4. Coverage: Automated testing allows for more extensive test coverage. We can easily create holistic test suites. They can cover various functionalities and user scenarios. This level of coverage is challenging to achieve with manual testing alone. After automating tests, we can easily ensure that no part of the application is left untested.
When you know when to use automation testing, you know what to automate. Here are some guidelines that I follow for when to automate software testing:
1. Stable Features: You need to automate tests for features that are not frequently changing. This way, we can validate their functionality quickly and reliably. If a feature is undergoing constant changes, the maintenance overhead for automated tests may outweigh the benefits.
2. High ROI: It is wise to automate tests that provide a high ROI. This includes checks that are run frequently. Often, they have a significant impact on the application’s overall quality. So, as we focus on high ROI tests, we can maximize the benefits of automation testing. It often guarantees that our efforts are well-spent.
3. Critical Functionality: You can use automation to check for critical functionality. For such features, failure would have severe repercussions. For example, millions of transactions occur daily on Amazon. So, you need to ensure their smooth processing. An error here could lead to incorrect charges. It might happen that the customers end up receiving the wrong items. So, here, automated tests help a lot. With it, you can verify that critical functionalities are working correctly and consistently. This continually reduces the risk of catastrophic failures.
4. Data-Driven Testing: You should embrace automation for checks that require running the same set of tests with different data inputs. So, this is particularly useful for validating functionalities that depend on various input combinations. Automation allows us to efficiently test multiple scenarios. You can do this without manual intervention.
5. Regression Suites: Another good area with automating is regression tests. With this step, the new changes added by your team will not break existing functionality. I have experienced regression testing as a very labor-intensive aspect of manual testing. Automation simplifies this process to a great extent. You can run regression suites quickly and accurately. Now, our application will be certain to remain stable over time.
