[Feature]: Sensible to perform integration/unit tests using PowerShell's Pester (with psake)?

Description

Just a question here -- I was wondering if the testing code documentation restricts testing of terraform module's to just the terratest golang framework.

I have been using a combination of the following PowerShell (Core) modules lately with my Terraform projects and find it to be very fluent:

• Az: Azure Suite of PowerShell Modules
• Pester: Tests
• psake: Task Runner
• Plaster: Module templating and best practices
• PSDepend: Dependency Management and Versioning
• Crescendo: (Optional) Could be used to create custom wrapper utilities for classic terraform-cli commands/scenarios (for example converting terraform plan to JSON or setting up the remote-backend / service principal, etc.)
• CredentialManager: Manage credentials and authentication
• platyPS: Generate documentation similar to terraform-docs does (although I still prefer terraform-docs here).

Similar to how PSRule (see Validate infrastructure as code (IaC) and objects using PowerShell rules) works nicely with Bicep or ARM Templates; I feel like these PowerShell tools really integrate nicely with the Terraform infrastructure as code ecosystem, specifically for Azure infrastructural deployments.

It also is a more friendly interface to use for a typical Azure developer that is more likely used to PowerShell syntax and development over Go, especially if having to write complex tests (notice the similarities between Pester/psake/DSC syntax and Terraform configuration syntax?).

Just wanted to see if anyone had any food for thoughts on this subject - any criticism or feedback would be much appreciated.

Thanks!

Hi @jimbrig

Go is idiomatic of Terraform, historically. Due to this, I have created a fluent testing module in go, it allows code that is much more easy to read. It is built atop terratest.

See here: https://github.com/Azure/terratest-terraform-fluent

That's not to say we can't investigate other testing frameworks, but this might be worth considering.

@matt-FFFFFF - Awesome, thanks for that - will check it out. I'm starting to try and learn Go regardless due to the fact it teaches design patterns and best practices relevant across any language/framework.

Thanks @jimbrig for the suggestions! I'll take a look at the tools that you recommended.

CredentialManager: Manage credentials and authentication

We're using MSI as the authentication method, we're also considering OIDC.
