Automated Testing for Continuous Delivery
Continuous delivery can be incredibly lucrative for companies looking to release new features quickly and stay in front of their customers’ expectations. However, without an effective testing strategy to keep up with rapid development, releases could be buggy or delayed.
To combat this, many companies are leveraging automation as part of a continuous testing strategy to keep the CI/CD pipeline running smoothly.
What Maintenance is Involved in Automating Tests?
While continuous testing is a great solution, there is a certain amount of maintenance involved in automating your tests. In fact, of the 135 industry professionals we surveyed, over 80% agreed that maintenance efforts for automated testing are increasing.
As your company scales to meet market demand, or as features are added and your platform evolves, your automated test suite will need attention to address any problems that arise and ensure it continues to run smoothly.
5 Strategies to Reduce Maintenance in Automation Tests
While maintenance is a necessary part of automated testing, we have come up with 5 simple strategies you can put in place to reduce both the workload and the headache of testing maintenance.
1. Empower your UI/UX developers to keep testing in mind
Work with your UI/UX (user interface/user experience) engineers to develop a static naming convention for objects in the user interface.
UI regularly changes to give users a fresh or more user-friendly experience. Often times, UI/UX engineers do not have testing at the forefront of their mind when writing code. By working with them to identify a naming convention, a static quality assurance (QA) id can be added to each object’s code.
As other aspects of UI/UX design and code change, your tests scripts will continue to recognize objects based on this stable QA id, minimizing the chance that changes in your design cause problems for your test suite.
2. Be strategic when creating your automation design: keep things simple.
While this is sometimes easier said than done, use simple test scripts as often as you can. We recommend using low-level tests that are easy to maintain and execute quickly, such as unit tests or automated API tests. By keeping your scripts as simple as possible, your maintenance efforts will be low.
For long or complicated scenarios, create reusable automated test cases and try to limit overcomplicating your test suite with complex test cases.
Complicated test suites create more opportunity for breakdown, so keeping things as simple as you can will reduce maintenance in the long run.
3. Develop a smart strategy for test execution
Ever hear the phrase “work smarter not harder”? Well, that applies to testing. You do not need to run a full test cycle every time you deploy new code.
We recommend implementing nightly automated testing that cover all test cases. These are not the mission-critical tests that determine whether a release is ready for deployment but rather regular maintenance tests.
Based on the results of this automated testing cycle, you can appropriately delegate efforts to either address or further explore issues identified in the nightly tests or perform maintenance on the automated test suite.
4. Establish a process to keep automation up to date
When designing and implementing your testing process, you want to consider the longevity of your process. Have you put a system in place to regularly check and update your test automation scripts? If not, do it!
If your team is delivering features and continually improving your application (and we sure hope they are!) then the reality is, your tests scripts will need to follow suit. Having a strategy in place to know when and how to update your tests will prevent things from slipping through the cracks and save work in the long run.
5. Identify and reduce flaky tests
So, what is a flaky test? These are tests that produce inconsistent results, even when run under the same parameters. Particularly prevalent in UI testing, flakiness is an error in the test setup, not in the development code.
To determine if a test is flaky or has simply failed, automatically re-run failed tests. If a test continuously fails, it is likely an issue with the development code and is not a flaky test.
If the failed test passes when you run it again or produces inconsistent results, then you have found a flaky test.
Flaky tests are an unfortunate reality of continuous testing, but identifying and responding to them quickly is an important step in maintaining your test suite.
Don’t let maintenance deter you from realizing the advantages of automation. Trust us, the benefits far outweigh the maintenance efforts…especially if you minimize those efforts with our simple tips!
