At [VZ4](https://app.codecrafters.io/courses/shell/stages/vz4), I get the following error:

```auto
Initiating test run...

⚡ This is a turbo test run. https://codecrafters.io/turbo

Running tests. Logs should appear shortly...

```

The error `[tester::#VZ4] Expected file "/tmp/foo/baz.md" to exist. Error: open /tmp/foo/baz.md: no such file or directory` seems to be generated out of order (before executing the next command `$ echo 'Maria file cannot be found' 2> /tmp/foo/baz.md`)

Hey @ShahriarJavidi, thanks for highlighting the issue! We’re addressing it in [this PR](https://github.com/codecrafters-io/shell-tester/pull/156).

Let me know if you notice anything else or need help with anything!

Just a quick note: while the error message appears before the command, the command is actually executed first. It’s just a display order issue.

This should be fixed now. Feel free to test it and let me know if anything’s still off.
