7# Purpose: Pester test runner that writes summary and failure details to logs/
8# Author: HVE Core Team

10#Requires -Version 7.0
11
12<#
13.SYNOPSIS
14 Runs Pester tests and writes structured output to the logs/ directory.
15
16.DESCRIPTION
17 Wraps Invoke-Pester with the repository's Pester configuration and writes
18 logs/pester-summary.json (pass/fail counts, duration) and
19 logs/pester-failures.json (failure details with error messages and stack traces).
20
21.PARAMETER TestPath
22 One or more paths to test files or directories. Defaults to the scripts/tests/ directory.
23
24.PARAMETER CI
25 Enables CI mode: NUnit XML output, exit-on-failure, and GitHub Actions log format.
26
27.PARAMETER CodeCoverage
28 Enables JaCoCo code coverage reporting to logs/coverage.xml.
