Pester is a framework that guides you to write, structure, and run PowerShell unit tests, mocks, and verification patterns efficiently.
Install the Pester module, create a simple test file named Example.Tests.ps1 with Describe and It blocks, and run Invoke-Pester to execute tests.
High-intent search queries and answers about installing and using this skill.
Structure PowerShell unit tests by nesting Context blocks within Describe blocks to group related test cases. This organization clarifies test scenarios and scopes mocking behavior effectively within your Pester test suite.
The two-phase discovery and run process in PowerShell testing first scans test files to collect Describe blocks, then executes the tests. This separation ensures accurate test enumeration before running, preventing discovery errors from halting execution.
Mock PowerShell commands and native tools in unit tests by replacing their behavior with controlled outputs using Mock. This isolates the code under test, ensuring CI pipelines validate logic without triggering actual system changes.
Yes, you can integrate PowerShell test results and code coverage into CI pipelines. Configure test reporting to output structured formats, enabling automated CI systems to parse results and track code coverage metrics.
TestDrive and TestRegistry provide temporary file system and registry locations for PowerShell test isolation. They automatically create and tear down these sandboxes, ensuring tests do not leave residual state on the machine.
Pester tests fail to discover correctly in a PowerShell project when syntax errors or improper block nesting exist during the discovery phase. Ensure your Describe and It blocks are structured properly to avoid discovery failures.
