Test automation can be an effective piece of the QA strategy puzzle for any team looking to optimize their testing process. Done well, it can speed up software testing cycles, improve the efficiency of QA teams, and ultimately increase product quality. However, contrary to popular belief, test automation is not a magical solution to achieve cheap, lightning-fast, effortless QA results.
Test Automation will always become expensive when the expected benefits and ROI are not delivered. The key challenge is that 99% of automated testing tools require code to be written. That means a massive amount of time and effort must be invested, so the expected benefits must be equally massive.
Many companies historically relied on manual testing. Automation was expensive due to following reasons:
1. Automated tests require technical expertise to continuously manage tests and the environments in which they run. Test automation experts are highly sought-after and often demand competitive salaries. As a result, hiring out a team to continuously keep automated tests aligned with the code can be a significant expense.
2. Time is money. To write scripts, tests, and make them work requires time. We’re talking time and effort here. And time means money. Writing test scripts is slow, painstaking, and hard. At every stage, you have to debug and test your test script. Then you have to modify the script for each browser and platform you need to test it on. As a result, even a simple test script takes a skilled engineer several days to get right.
3. When application changes are made to features, that indirectly influences automated tests and the tests might break. When evaluating the cost of incorporating automation into your QA strategy, consider how frequently automated tests will need updating to stay useful.Every time you make a change to your UI tests tend to break. Even minor changes will affect the selectors that the test script interacts with. The upshot is that most test engineers now spend half their time performing routine test maintenance.
4. Hidden Cost of Automation is Delayed Release Timelines. This is especially problematic if you have developers maintaining your automation test suite. Automated tests can fail because there is a bug, but they can also fail because the test itself is broken. If your team is in the middle of launching a release and your automated tests fail, you’re not likely to continue with the release until the source of the failure is identified, because there might be problems with software quality.
