# Testing Methodology at Portainer

What testing is done of the Portainer and Agent software?

### Release Testing

Before a release is initiated, the entire Portainer team dedicate time to complete comprehensive testing of the `portainerci/portainer:develop` & `portainerci/agent:develop` images.

Due to the complexity of the codebases, merged pull requests have the potential to interact with each other and cause bugs. If a bug is found, it is fixed, pushed and re-tested to ensure that the release is bug free. To get an idea of the testing that we do for a release, see the attached file below.
