Pester is the ubiquitous test and mock framework for PowerShell, providing a Describe/Context/It DSL with Should assertions and powerful command mocking. It supports unit and integration testing, code coverage, and test result reporting for CI pipelines.
Use cases
- write unit tests for powershell functions
- mock cmdlets in powershell tests
- run powershell tests in ci pipeline
- measure code coverage of powershell module
- test infrastructure and deployment configurations
- bdd-style testing in powershell
- assert powershell script output
When to choose
- you are writing or maintaining PowerShell modules or scripts and need automated tests
- you need mocking of PowerShell commands without dependency injection
- you want code coverage and test result artifacts for CI pipelines
When to avoid
- you are testing code in languages other than PowerShell
- you need a general-purpose test runner outside the PowerShell ecosystem
