About the test
The DevOps online test assesses knowledge of practices and tools of the DevOps lifecycle, such as understanding of source control using Git, key performance indicators, and project lifecycle best practices.
The assessment includes work-sample tasks such as:
- Using continuous integration to prevent integration hell.
- Determining appropriate KPIs for creating reports.
- Merging branches with Git version control.
A good DevOps engineer or developer should be able to combine software development and information-technology operations, in order to build, test, and release software faster and more reliably.
Sample public questions
Your company has been working to increase its frequency of deployment for new features by optimizing its full development and operating lifecycle. The CEO wants to cut unnecessary phases to deliver new features to the customer.
Which phases are not part of the core DevOps lifecycle?
A developer is experimenting with code on a local copy of a branch. After a while, it is decided that this experiment does not work. So the developer decides to switch back to the master branch. However, the developer's local working copy is different from the HEAD.
Which of these options would allow the developer to successfully check out the master branch?
The CEO of your company understands that sometimes things go wrong. No system is perfect, but she wants to ensure that the company is improving.
Which metrics could be used to track the company's incident management?
Write down a sequence of GIT commands (with no additional arguments) to download a repository, update a file, and save the changes back to the original repository. Assume that other developers didn't modify the file.

git _____ https://email@example.com/testdome.git
- Fix a bug in file test.cpp
- Mark that file test.cpp has been changed:
git _____ test.cpp
- Save the changes to the local repository:
git _____ -m 'Bug with testing is fixed'
- Send the changes to the original repository:
git _____ origin master

What others say
Simple, straight-forward technical testing
TestDome is simple, provides a reasonable (though not extensive) battery of tests to choose from, and doesn't take the candidate an inordinate amount of time. It also simulates working pressure with the time limits.
