Description: The ‘Test-Script’ cmdlet in PowerShell is a tool designed to evaluate scripts for errors before execution. This cmdlet allows developers and system administrators to verify the syntax and logic of their scripts, ensuring they behave as expected and minimizing the risk of failures during execution. ‘Test-Script’ integrates into the development workflow, providing an efficient way to debug and validate code. By using this cmdlet, users can identify potential issues such as syntax errors, undefined variables, or logic problems, making it easier to create more robust and reliable scripts. The ability to perform pre-execution testing is crucial in production environments, where errors can have significant consequences. In summary, ‘Test-Script’ is an essential tool for anyone working with script development and execution in various programming environments, as it improves code quality and reduces the time spent on post-execution debugging.
