Let us to have a closer look at the key Test Automation Benefits
Test automation approach is designed to increase the overall software efficiency and ensure robust software quality.
There are specific tools that can effectively execute automated test cases and help in comparing actual and expected results. So, test automation can guarantee software proficiency without involving repeated and manual intervention. One of the biggest business perks of test automation is that it can be implemented repeatedly with minimal effort and maximum accuracy.
Faster feedback. Without test automation, feedback for newly developed features can take a while. Test automation helps to reduce the feedback cycle and bring faster validation for phases in the development of software product. Test automation is especially useful because it allows detecting problems or bugs early on during the development phase, which increases the team's efficiency and saves costs. It is commonly known that the cost of fixing a defect found at the early development stage is significantly lower that fixing the same bug after release.
Accelerated results: Owing to the quick implementation of automated testing, plenty of time is saved even for intricate and enormous systems. This allows for the testing to be carried out repeatedly, delivering faster results each time with lesser effort and time.
Reduced business expenses: When using an automated test environment, your company will save money as fewer resources are spent on testing your product. The idea is that you should not be doing any manual testing. Over the course of a whole project, this can make a big difference. Of course, installing and setting up an automated testing environment takes time and resources. Also, chances are that you'll pay for a proper test automation tool that can assist you in creating a stable test automation environment.
Reusability of Test Suite. At first, building your automated test suite is a challenge. However, once you have defined your suite, it's very straightforward to reuse test scripts for other use cases or even other projects. The advantage is that you can easily hook up another project to your automated test suite. You've already gained a thorough understanding of setting up an automated test suite and all related tools such as a continuous integration (CI) pipeline. Therefore, you can easily replicate this knowledge to set up your test automation for a new project.
Higher overall test coverage: Through the implementation of test automation, higher number of tests can be executed pertaining to an application. This leads to a higher coverage, which in a manual testing approach would imply a massive team, limited heavily with their amount of time. An increased test coverage leads to testing more features and a higher quality of application.
Earlier detection of defects: The documentation of software defects becomes considerably easier for the testing teams. This helps increase the overall development speed while ensuring correct functionality across areas. The earlier a defect is identified, the more cost-effective it is to fix the glitch.
Thoroughness in testing: Testers tend to have different testing approaches, and their focus areas could vary due to their exposure and expertise. With the inclusion of automation, there is a guaranteed focus on all areas of testing, thereby assuring best possible quality.
Faster time-to-market: Test Automation greatly helps reduce the time-to-market of an application by allowing constant execution of test cases. Once automated, the test library execution is faster and runs longer than manual testing.
Information security: The effectiveness of testing will be largely dependent on the quality of the test data you use. Manually creating quality test data takes time and as a result, testing is often performed on copies of live databases. Automation solutions can help with creating, manipulating, and protecting your test database, allowing you to re-use your data time and again. The time and cost savings in this area are potentially huge.
Automated testing provides better insights than manual testing when some tests fail. Automated software testing not only gives insights into the application but also shows you the memory contents, data tables, file contents, and other internal program states. This helps developers determine what's gone wrong.
