In the last few years, DevOps has established itself as a must-have for all the most innovative companies. Many companies have adapted a continuous approach to software delivery and development, using one of many popular technologies and tools. However, the most important way to improve continuous integration strategies is to change the company’s processes by examining the frequency and scale of tests running throughout the development cycle. These tests help speed up the process by helping to identify and fix trouble spots in apps while the changes are still fresh in the developers’ minds.
The following are a few of the mistakes that companies make when it comes to DevOps, and how to fix them.
Choosing Speed Over Quality
Many companies get too focused on the importance of speed in DevOps that they allow things to be rushed out the door with little to no testing. You can’t have both speed and quality. However, you can equip dev teams to write their own tests with their own tools for quick feedback for every build and deployment candidate possible.
Testing for Problems Only at the End of the Lifecycle
This is a common misconception about load testing. Many people still think that it could only be done at the end of the lifecycle and that they have to wait for the performance tests to be developed and run by someone else. But this method creates surprises and unnecessary drama for everyone involved. However, with modern, open-sourced tools and domain-specific languages, developer driven performance testing is now possible and should be taken advantage of. With developers taking responsibility for functional tests, they are beginning to use low-volume performance tests to examine functionality and performance in one shot, especially with API endpoints, which become building blocks for automated integration, deployment, and post-production tests.
Running Just One Test at a Time
Another mistake many companies make is thinking that tests must be run one at a time, which combined amounts to a significant amount of time wasted. Instead, you can run all of your small tests simultaneously, saving you lots of time.
Assuming Your Tools Aren’t Compatible
When developing an app, the use of open-source tools have become common among developers, with many developers having a favorite tool that they use consistently. Oftentimes they are then wary to use other tools imposed on them by others. With many frameworks emerging that are compatible with a wide variety of tools, this should no longer be a problem, as long as you can have a unified orchestration framework that individual tools can tap into. However, regardless of what tool you use, the process of load testing can be part of a single, unified whole without restricting tool choice.
Not Communicating Testing Expertise and Sharing Responsibility
With DevOps becoming more popular, the roles and responsibilities of the developer teams are becoming less defined. Some teams dedicate members of the team to a select few “engineer in test” developers, limiting the ability for tests to run throughout all stages of the lifecycle. However, the responsibility to create high achieving performances and breaking silos should fall on everyone’s shoulders equally and should occur throughout the process, not just at the end.
Limiting Tools Developers Can Use
When companies are large and have large departments, many DevOps members can struggle under the single companywide set of tools. Instead, what many companies are doing, is setting up smaller, self-sufficient teams that run on their own, with minimal interactions between teams. This way, each team can set up DevOps and continuous delivery tools and technologies that work for them and meet their needs.
Forgetting About the Database
One key area often missed out when adopting DevOps is database. While DevOps rapidly expands, the database lags behind because of a mistrust in automating the database. If the code is on steroids but the database is limping behind, it can hold back the entire development lifecycle.
