Test automation is a key part of any QA strategy, especially when you have a large number of test cases or you have a product that keeps growing in size and complexity. Test automation speeds up a time to market by expediting the time to software improvements.
An efficient automation strategy includes hidden costs, managing tests, and hiring quality resources. However, there are certain limitations to it. So, test automation is not something magical that can lead to success. There is a certain limitation to it as well. Some of the limitations of test automation are discussed below.
1. It Must be Designed for Repeatability
It’s a common perception that test automation gives you quality feedback with a quick click of a button or a command. However, this can only work if cases are set up with the concept of repeatability because it requires a lot of time to set up test cases. So, if it cant be repeated after lots of effort you won’t get the actual value of test automation. So, it is important to optimize for ROI by continuous repeatability.
2. Product Must be Stable
In order to get the best out of an automated test case, your product must be stable. Technical leaders often expect that automation would accelerate and streamline the development cycle. However, not every test case is great for automation. So, it could be quite a pitfall when you get too hard into test automation.
3. Technical Expertise and Skills
Automated test cases require technical skills and expertise as it is not a plug and play process. Test scripts require a high level of expertise and technical skill. The greatest limitations of test automation probably would be this. You must consider the pros and cons while using technical expertise as it is very expensive and limited in number.
