What it is

This nuget contains some Xunit 3 Assert extensions for handling multiple assertions which depend on each other's assertion result:

  • EitherOr(assertions) and its alias Xor(assertions): Passes if exact one of the passed assertions passes and all others are failing.
  • NeitherNor(assertion): Passes if all passed assertions are failing.
  • Or(assertions): Passes if at least one of the passed assertions passes.
  • PassesExactly(min, max, assertions): Passes if the number of passing assertions lies in the inclusive range min <= passings <= max. Ignores Checking a range boundary if it is null.
  • IfPass(assertion1).Then(assertion2).Else(assertion3), its alias If and the opposite function IfFail check assertion2 only if assertion1 passed (or failed in the latter case), else (if defined) it checks assertion3.

Example

Assert.EitherOr(
  () => Assert.Equal(2, primeNumber),
  () => Assert.Equal(1, primeNumber % 2)
);

Assert
  .IfFail(() => Assert.Equal(0, x))
  .Then(  () => Assert.NotEqual(0, 1 / x))
  .Else(  () => Assert.Equal("impossible", divisionState));
