@ -61,6 +61,25 @@ If the test includes playwright tests, you can see the playwright trace with:
$ nix run .#playwright -- show-trace $(nix eval .#checks.x86_64-linux.vm_grocy_basic --raw)/trace/0.zip $ nix run .#playwright -- show-trace $(nix eval .#checks.x86_64-linux.vm_grocy_basic --raw)/trace/0.zip
``` ```
If the test fails, you won't have the output directory available.
Instead, run the test with `--keep-failed` and at the end you will see a line saying
```
Keeping build directory '/nix/var/nix/builds/nix-31776-4270051001/build'
```
Copy the path and run:
```bash
sudo cp -r /nix/var/nix/builds/nix-31776-4270051001/build/shared-xchg/trace trace && sudo chown -R $USER: trace
```
Now, open that file with playwright:
```bash
nix run .#playwright -- show-trace trace/0.zip
```
