Continuous Development

Continuing on with the TestOps posts by the, well, awesome Awesome Testing blog, is Continuous Development. Which is actually very interesting as it was a large part of what was taught in my Software Process Management course last year, so it was an enjoyable surprise to see this as the next covered topic.

Generally speaking, Continuous Development is, according to Wikipedia, “the process of executing automated tests as part of the software delivery pipeline to obtain immediate feedback on the business risks associated with software development. ”

The first step is Continuous Integration and unit tests. After every single commit by a developer, the main branch app should be compiled and built, and then unit tests should b executed to give the quickest feedback possible. The post suggests using mutation testing, testing that adds random faults to your code to see how well your tests perform, to test the unit tests themselves to see how good they are. After that, the developer should be made aware of their commit changed overall code coverage statistics.

The next step is Continuous Delivery or Automated Deployment. One should do numerous test environment deployments to test the deployment process of the application as well. After this is testing higher level things, such as functionalities on the integration or API level. End to end testing is very expensive, resource-wise, and should be done sparingly.

After that is performance testing, using a testing environment as close to the production environment as possible. You want to see how the application handles heavy loads. And then is security testing, to make sure the application is as safe from being hacked as you can manage, and then the hardest step, exploratory testing. This is a manual exploration of the application, that takes a lot of time and resources. It should be done sparingly as well.

Overall, this was another nice intersection between software development and testing. It was also a good reminder of concepts I learned in the very recent past which I found very interesting at the time. The ability to streamline the process for a developer and to give them feedback as quickly as possible is incredibly important, its ability to foster greater productivity readily available. To create such, there a many useful tools out there for testers and developers alike. Its a very straightforward example of testing directly helping developers, which is nice to see.
