 # Testing
-The code can be tested with [nox](https://nox.thea.codes/en/stable/)
+The code can be tested with [hatch](https://hatch.pypa.io/latest/tutorials/testing/overview/)

+* `hatch test` can be used to test all supported python versions and to check for coverage.
+* `hatch test -py 3.10 -- --sw` runs pytest for python 3.10 with the `--sw` argument.
+
+The preferred way to test inline-snapshot is by using [`inline-snapshot.texting.Example`](https://15r10nk.github.io/inline-snapshot/latest/testing/).
+You will see some other fixtures which are used inside the tests, but these are old ways to write the tests and I try to use the new `Example` class to write new tests.
 
-* `nox` can be used to test all supported python versions and to check for coverage.

 # Coverage
-This project has a hard coverage requirement of 100%.
+This project has a hard coverage requirement of 100% (which is checked in CI).
+You can also check the coverage locally with `hatch test -acp`.
 The goal here is to find different edge cases which might have bugs.
 
 However, it is possible to exclude some code from the coverage.
