# Testing
|
|
|
|
Testing is always an important aspect of any software development project, and
|
|
NixOS offers some incredibly powerful tools to write tests for your
|
|
configuration, and, optionally, run them in
|
|
[CI](./integrations/hercules.md).
|
|
|
|
## Unit Tests
|
|
Unit tests can be created from regular derivations, and they can do
|
|
almost anything you can imagine. By convention, it is best to test your
|
|
packages during their [check phase][check]. All packages and their tests will
|
|
be built during CI.
|
|
|
|
## Integration Tests
|
|
All your profiles defined in suites will be tested in a NixOS VM.
|
|
|
|
You can write integration tests for one or more NixOS VMs that can,
|
|
optionally, be networked together, and yes, it's as awesome as it sounds!
|
|
|
|
Be sure to use the `mkTest` function from digga, `digga.lib.pkgs-lib.mkTest`
|
|
which wraps the official [testing-python][testing-python] function to ensure
|
|
that the system is setup exactly as it is for a bare DevOS system. There are
|
|
already great resources for learning how to use these tests effectively,
|
|
including the official [docs][test-doc], a fantastic [blog post][test-blog],
|
|
and the examples in [nixpkgs][nixos-tests].
