Test pass 🎆

Have a look at descriptions and default values for variables client_certificate_mode and client_certificate_enabled in this PR: equinor/terraform-azurerm-web-app/pull/215

Should probably go for a similar implementation here 🙂

[kov117]

agreed and appreciated for the heads up 🫶

I think this looks good now, however the client_certificate_mode argument has no effect without the client_certificate_enabled argument. We should have a variable for that as well (see link to relevant PR in my previous comment).

Noted, should i include it to the tftest config as well ?

@kov117 some of the windows_client_certificate_* tests refer to the azurerm_linux_function_app resource.
