CodoMetis.TypeKit.Testing

Test assertions for the Option and Result of CodoMetis.TypeKit. Neither type has a .Value, so a test reaches the content through these, and fails with what the outcome was instead.

dotnet add package CodoMetis.TypeKit.Testing   # the test project

using CodoMetis.TypeKit.Testing;

Email email = Email.Create("ops@example.com").ShouldBeSuccess();   // the value, for the test's own assertions
Email.Create("nobody").ShouldBeError(EmailFault.NoAt);              // this error, or the test fails
EmailFault fault = Email.Create("").ShouldBeError();                // any error, handed back

Email.TryFrom("ops@example.com").ShouldBeSome();
Email.TryFrom("nobody").ShouldBeNone();
  • The content comes back. ShouldBeSome(), ShouldBeSuccess() and ShouldBeError() return the value or the error, so it is compared with whatever assertions the test already uses: xUnit's Assert, Shouldly, or another.
  • No test framework. A failure is a TypeKitAssertionException, and every framework reports an exception from a test as its failure. The package depends on CodoMetis.TypeKit alone.
  • A failure says what the outcome was: Expected a success, but the Result<Email, EmailFault> is the error NoAt. It names the error, which is what a test needs to see, and never prints a value, as Option and Result themselves never do.
  • An uninitialized result fails every assertion, saying it is a default instance, neither a success nor an error.
