I’ve given the talk on How I Became an Automation Engineer a few times. Each time I’ve gotten good feedback and a lot of questions from engaged participants. With each repeated question, I try to update my talk to address those points for future audiences. However often I do this some repeated questions still arise. I’ve taken this challenge as both an excuse to write out my answers and try out a FAQ schema block!
Frequently Asked Questions
Ultimately your goal is to tackle the task at hand. Use the tools and languages that make sense.
No, probably not. Hopefully you work for an organization that wants to use the right tool for the right job.
Part of the process for learning about tools is we figure out what they are and aren’t good for. No one tool is good for all jobs. The same goes for the person using the tool. If you only know one tool you’ll try to use it for every problem. The more tools we learn, the more likely we will use the right tool for the right job. This also makes us more valuable in the market for new jobs.
It depends on your needs and your skills.
In the past, Record and Playback features were sold as Snake Oil. They’d fix all your problems. But they usually were much good beyond proof of concepts.
Today, more and more services are cropping up with codeless / record and playback capabilities. If these meet the needs of your project and/or company, then use them. One challenge for the individuals learning and using these these tools is they might not benefit your (market) value in the long term.
Test Automation is there to provide feedback, but it costs money and takes time to build and maintain. So if you are on a short term project then it might not be worth the time an effort to do certain kinds of test automation.
What kinds make sense? Well it depends on the project. It might be worth it to do unit tests but not much else. Or it might be worth it to build some one-off probabilistic automated tests to help you discover problems because it doesn’t have to be maintained. Remember the point of automation is to reduce our time or extend our capabilities but all that must be done within the context of your project.
Yes! In general I recommend automating tests at the unit level first, then at the service or API level and lastly at the UI level. Learning to explore APIs is a big part of this and eventually once you explore them, you can create automated tests.
Postman is a good tool for exploring APIs (there are probably others). It might also make sense for you to write some automated tests in Postman but that really depends on your goals and/or if there are better places to do it. This depends on your overall strategy.
We know that in high performing teams developers own the automated tests and testers are allowed to explore for risks. So there’s a high probability in companies looking to build high performing teams that Automation Engineering roles will disappear or not exist. There’s also a high probability of developer roles being needed in the future. We just don’t know when any of this will occur. If you are going to move, it makes sense to survey the landscape and see what the options are, see what your skill levels are and be practical.
