Catesta is a PowerShell module project generator. It uses templates to rapidly scaffold test and build integration for a variety of CI/CD platforms.


Catesta enables you to quickly scaffold a PowerShell module project with proper formatting, test + build automation, CI/CD integration, with just one line of code.

  • Catesta scaffolds an empty PowerShell module project that adheres to PowerShell community guidelines.
  • It generates a few Pester tests to get you started.
  • It makes a build file that analyzes your code for best practices and styling, runs Pester tests, creates PowerShell help, and combines your functions together to build your project for publication.
  • It will create resources you need to trigger CI/CD builds for your module.
  • When you commit your code to your chosen repository, the build(s) will run, and you can view the results.


Simplify the process of structuring your module so that you can focus on building a great PowerShell module instead of the layout and build requirements.

Getting Started

  1. Use Catesta to scaffold your PowerShell project with your desired CI/CD platform and builds.
  2. Write your module (the hardest part)
    • All build testing can be done locally by navigating to src and running Invoke-Build
    • If using VSCode as your primary editor you can use tasks to perform various local actions
      • Examples:
        • Press Ctrl+P, then type 'task .' - Runs complete build (all tasks)
        • Press Ctrl+P, then type 'task Test' - Invokes all Pester Unit Tests
        • Press Ctrl+P, then type 'task Analyze' - Invokes Script Analyzer checks
        • Press Ctrl+P, then type 'task DevCC' - Generates generate xml file to graphically display code coverage in VSCode using Coverage Gutters
  3. Add any module dependencies to your CI/CD bootstrap file:
    • AWS: install_modules.ps1
    • GitHub Actions: actions_bootstrap.ps1
    • Azure: actions_bootstrap.ps1
    • AppVeyor: actions_bootstrap.ps1
  4. Commit your project to desired repository that is integrated with your CI/CD platform. This will trigger the build actions.
  5. Evaluate results of your builds and display your README badges proudly!
