In other words, the tool would be checking environmental functions instead of hard-coding values. The tool utilizes knowledge on security practices for the language and uses the appropriate language construct for the task at hand. The philosophy behind ARTM TTK is to validate the author’s intent when writing the templates, such as checking against unused parameters or variables. These test cases are generic and designed to validate that your templates are following best practices. The tool is an open-source PowerShell library that you can use to validate your templates against a series of test cases.
ARM TTK Deeper DiveĪRM TTK or Azure Resource Manager template (ARM template) utilizes a list of preset unit test requirements for an ARM Template to receive a pass or fail. Another way to use Pester is to use it to validate any changes that were made to an already written script. Pester is a framework whose purpose is to ensure the PowerShell commands that are written, whether functions, modules, or scripts, do what is expected.
Check pester version how to#
By using the test toolkit, you can learn how to avoid common problems in template development.Īlthough also a tool to test a written piece of work, Pester is a little more complicated than ARM TTK. If your template isn’t compliant with the pre-set list of requirements, it returns an easy-to-read list of warnings with the suggested changes.

The tests will check a template or set of templates to code best practices when the tool is run.
Without knowing too much about writing code or developing ARM Templates, I was able to see how these tools are powerful and resourceful when writing PowerShell commands and creating ARM Templates.ĪRM TTK or Azure Resource Manager template Test Toolkit, test your ARM Templates by checking through a set of requirements that either pass or fail the test. During some time, I researched and was asked to add content to the Knowledge Center about testing tools Pester and Azure Resource Manager (ARM) Template. Throughout the history of writing code, tools have made it easier and more foolproof for developers to complete tasks and get increasingly better at test-driven development. Testing is and has always been a necessary action when writing code or creating templates.
