How do Unit Testing work with TinyGo

[hbroer]

Hi,

I did not found information on how unit tests work with TinyGo. I tried it with tinygo test pathto_test.go but it fails. Where can I find the information on how it works?

tinygo test fan/fan_test.go

tinygo test is not fully supported yet. I've been working on it but it doesn't yet work as well as go test.

Depending on your package, you could simply use go test instead.

tinygo test fan/fan_test.go

I have no idea what's going on here. Shouldn't C:\Go contain the regular Go installation instead of TinyGo? TinyGo requires there to be a regular Go installation separate from the TinyGo installation.

[hbroer]

Yes, C:\Go contains a regular Go installation. TinyGo is in C:\tinygo.

Edit: I think I cant use go test because I use machine.Pin etc.

[aykevl]

It appears that you have files from TinyGo in C:\Go (the panic.go error message can only come from a TinyGo runtime file). Perhaps you can try removing and reinstalling Go to fix this?

Edit: I think I cant use go test because I use machine.Pin etc.

Indeed, that would be difficult.

hm I don't think so:

My go app also run fine. Just tested it out.

Closing since it appears question has been answered. Thanks everyone!
