Assert.Inconclusive
The Assert.Inconclusive method indicates that the test could not be
completed with the data available. It should be used in situations where
another run with different data might run to completion, with either a
success or failure outcome.
Assert.Inconclusive();
Assert.Inconclusive(string message);
Assert.Inconclusive ends the test immediately by throwing an InconclusiveException, so nothing after the call runs.
Like Assert.Ignore, it may not be used inside a multiple assert block.
An inconclusive result does not affect the result of the containing fixture. Unlike an ignored test, it is not treated as a warning by runners. The VS Test Adapter reports it as Not Run. See Ignored, Inconclusive, or not run? for a comparison.
In NUnit 5 and later, any warnings issued before the call are included in the result message. In earlier versions only the inconclusive message is kept.
