Automation testing is a software testing technique that is done through specialized automation tools to execute test case suites. On the other hand, manual testing is performed by human beings manually executing the test steps.
Automation testing has many advantages. Following are a few top benefits:
Higher Test Coverage
Manual testing, due to the sheer effort it requires, puts limits on how many tests you can verify. Automation allows QA resources to spend time writing new tests and adding them to the automated test suite. This increases the test coverage of a product, so more features are properly tested resulting in a higher quality application. Furthermore, automated testing enables writing more in-depth tests that test complex use cases. Lengthy tests that are often avoided during manual testing can be run with much more ease.
Faster Feedback Cycle and Time to Market
In manual testing, feedback for newly developed features can take a while. Test automation helps reduce the feedback cycle and bring faster validation in the development of a product. Automation especially helps detect problems or bugs early on during the development phase, increasing the team’s efficiency. As a result, newly developed features can be continuously tested and validated with test automation, allowing for companies to bring their products to the market faster.
Automated testing provides better insights than manual testing when some tests fail. It not only gives insights into the application, but also shows the memory contents, data tables, file contents, and other internal program states. This helps developers determine more conveniently to find out what went wrong.
Increased Accuracy and Productivity
Manual testing opens up possibilities to make human errors. This is especially true for complex scenarios, where ensuring painstaking and tedious detailing can be extremely tough. While mistakes can still happen in automation testing, the rate of mistakes is significantly lower when using test automation for your test suite. And since automated tests don’t require any human intervention while running, it is possible to have automated tests running at nighttime and harvest the results the next morning – significantly saving human resources for critical tasks.
Executing repetitive tasks with automated software testing gives your team time to spend on more challenging and rewarding projects. Team members improve their skill sets and confidence and, in turn, pass those gains on to their organization.
Although test automation is hugely recommended, not all organizations can readily embrace it in its entirety. A huge reason is the initial cost of configuring the automated testing process. It is thus important to on-board a vendor that understands your testing needs and customizes the test automation tool depending on your specific budget and requirements. Remember, the end goal of automation is not to eliminate manual testing; it is to provide ROI, a better product, and efficient utilization of your resources.
