Octopus

Overview

Octopus is a testing framework that allows you to run tests defined as Docker images on a running cluster. It was created to replace the helm test by providing these additional features:

• Selective testing, which is especially useful for local development when you want to execute only tests that local changes can affect.
• Automatic retries on failed tests, which is a remedy for flaky tests.
• Running tests multiple times, which is helpful when you add a new test and you want to validate if it is stable, or when you want to reproduce a problem that occurs on CI.
• Full support for concurrent testing, which allows you to specify how many tests should be executed at the same time.
