Automation Tip 7–Testing


One of the great things about automation is the ability to achieve consistent results, same thing every time, but go careful. What happens for example if your automation task is incorrect, if it doesn’t achieve what you want it to do.

Guess what?

You will get the undesired result every time.  Or as I like to say, you will retrieve mass produced crap!

This is exactly why testing in automation is key, both functional and scale testing, what happens when you start working at a larger scale, do things still react in the same way, do you still get the desired results?

Sometimes testing will show areas where throttling mechanisms may need to be used, take for example the ability to create a virtual machine, when we automate this we may produce 10 virtual machines in the same timescale, maybe 100, 1000 or even more.  Does your hardware allow you to do this? How does the storage or the network or the IP management system manage working at this rate? Throttling may cause a slight delay in the process but it will certainly ensure everything is available for future workflows.

In summary, testing will help you be aware of your bottlenecks and stop mass produced crap!
