This project is used and loved by many in the Kubernetes community. While we are not aware of everyone using the project, below is a list of adopters (and/or contributors) who have agreed to share how they use the framework in their porjects.
If you are using the e2e-framework to test your Kubernetes components, and you want to share your story, feel free to open a PR and add to the list below.
Crossplane has ported all of their integration tests to use e2e-framework for their Crossplane project. See their work here
Datadog has ported their e2e tests from the Kubernetes e2e test framework to the e2e-framework. The e2e-framework is also used to test different controllers.
We are thrilled that there are many other public projects on GitHub that use the e2e-framework.
