feat: Added first version of a CI-focused testing pipeline (#2459)
Browse files Browse the repository at this point in the history
## Description

- Added first version of a CI-focused testing pipeline 
- Runs by default once a week - and for every merge to main if utilities
are changed
- Added test script for resource sorting script

The idea is to build atop this initial setup with future tests and as
such enable regression tests

.SYNOPSIS
This script executes either all CI-focused Pester tests, or a specific test file and generates a markdown with the test results.
.DESCRIPTION
This script executes either all CI-focused Pester tests, or a specific test file and generates a markdown with the test results.
It only considers test files in its current or sub-folders
.PARAMETER RepoRootPath
Optional. The root of the repository. Used to correctly resolve paths.
.PARAMETER BranchName
Optional. The branch to test for.
.PARAMETER GitHubRepository
Optional. The repository containing the test file. If provided it will be used to generate a URL to the exact line of the test.
For example: 'Azure/ResourceModules'
.PARAMETER TestFileRegex
Optional. The regex to use when searching for test files
.PARAMETER SkipOutput
Optional. Set if you don't want the script to generate the results markdown
.EXAMPLE
Test-CI
Invoke all CI-focused Pester tests and generate a markdown file with the test results.
.EXAMPLE
Test-CI -TestFileRegex '.*Ordered.*' -SkipOutput
Invoke all CI-focused Pester tests that match the regex '.*Ordered.*' skip the generation of the markdown file containing the test results.
