Tests for Stage #UN3 (Redirection - Append stderr)

[steal9pro]

I’m stuck on Stage #(UN3).

My tests pass in terms of current stage, but it fails on Redirection - Append stderr.
It doesn’t looks it should.

I test locally and everything works expected. I can’t understand the reason of fail.
If we run with 2>> then file should not be empty. Am I missing something?

Here are my logs:

Hey @steal9pro, I tried running your code locally and noticed that a couple of things aren’t working as expected:

• 2.txt should contain something, but it appears to be empty.
• 1.txt should be empty, but it contains something.

If we run with 2>> then file should not be empty. Am I missing something?

I know it’s hard to tell, but our tester tries to assert that 1.txt (or /tmp/qux/baz.md in your example) stays empty.

Let me know if you’d like further clarification!

I see, found a bug.
It’s a tricky one, thank you
