This can include functions, Cmdlets, Modules and scripts. Pester tests can execute any command or script that is accessible to a pester test file. Pester follows a file naming convention for naming tests to be discovered by pester at test time and a simple set of functions that expose a Testing DSL for isolating, running, evaluating and reporting the results of PowerShell commands. Pester provides a framework for running Unit Tests to execute and validate PowerShell commands. In both development approaches, tests are written ahead of the code, but in BDD, tests are more user-focused and based on the system’s behavior. It is also a base for tools that validate whole environments, computer deployments, database configurations and so on. Pester is most commonly used for writing unit and integration tests, but it is not limited to just that. Pester provides a framework for writing and running tests. It differs by being written in a shared language, which improves communication between tech and non-tech teams and stakeholders. Pester is a testing and mocking framework for PowerShell.

Pester is a framework specifically designed to unit test PowerShell scripts. Pester powershell code#For that Should command is used – it compare result of code in It block with expected result. Command included in It block will throw an error in case that test of command will fail. It – should be used inside of Describe or Context commands. Usually used to group specific types of test (in my example services, disk space, RAM). I want to share with you basic example of using Pester commandlets.ĭescribe – define name of the test group under which Context and It blocks exists.Ĭontext – define grouping of It blocks. Pester is quite fresh framework which is user friendly and very easy in implementation. Today let’s talk a little bit about framework for Powershel script testing called Pester.
