Set‐TestInconclusive

This is a command that you can use to neither test nor fail a failure. Instead, Pester will just throw its metaphorical hands up and tell you it doesn't know what's going on. This is a great command to use in pre-testing because if a dependency isn't there before the test runs, the test cannot pass or fail because it won't run in the first place. Set-TestInconclusive is a perfect command to run when a dependency does not exist.

The quote from Adam's Bertram article Working with infrastructure dependencies in Pester.

Set-TestInconclusive was introduced as the respond for the issue 395, the pull request 421.
