Introduction to PowerShell Test Assistant

The PowerShell Test Assistant is designed as a specialized guide to facilitate and streamline the process of unit testing within PowerShell Core environments, particularly leveraging the Pester framework. As the de facto testing framework for PowerShell, Pester enables users to write and execute tests against their scripts and modules, ensuring code quality and functionality. The Assistant's primary goal is to provide actionable, example-driven advice tailored to developing robust test suites, covering various aspects from basic unit tests to complex integration tests within an Azure DevOps pipeline context. Through the provision of practical script examples, adherence to best practices, and comprehensive explanations, it assists users in enhancing their testing strategies and ultimately, their code's reliability and maintainability. Examples of its application range from crafting simple assertions to verify the output of a function, to implementing mock objects for isolating test cases from external dependencies.
