CLI/TUI Testing Package

[trymeouteh]

I find it strange that it is rare or non existent to find good tools for testing CLI apps or TUI apps. The only thing I can find is tui-test which is made by Microsoft. Looks great but it is written in TS and therefore the test will be written in JS or TS which I personally think is fine for testing CLI or TUI apps that are written in JS or TS.

I would like to suggest the creators of Bubble Tea to create a Go package that is the equivalent of Microsoft tui-test but in Go and allow devs to easily make test in Go to test out there CLI apps and TUI apps.

To be able to test out these scenarios (These are the scenarios I can come up with)

• Terminal input stdin git git --help
• Terminal output stout
• Terminal stderr
• Interacting with TUIs (Buttons, checkboxes, etc)
• Snapshots
• Works on my shell/device
• Can be used to test uncompiled Go apps, or any other compiled app written in any language

Would like to make my tests for a CLI app and TUI app written in go have their tests written in Go as well and not another language to add more complexity to the project by needing to know JS/TS to maintain the tests.

It's not necessarily as robust as you're hoping, but this already exists. Might get at some of what you're hoping for :)
