Cant Understand the difference between #PN5 and #FF0

in #PN5 (The exit builtin) test case for
input: invalid_mango_command
expected output: invalid_mango_command: not found

but for the test case #FF0 (REPL)
input: invalid_command_1
expected output: invalid_command_1: command not found

How do i know when i need to output not found and when to output command not found?

Hi @sgupta98mnit, thanks for highlighting the issue! We’re working on fixing it and will keep you updated.

In the meantime, you can output command not found to pass both stages for now.
