CodoMetis.TypeKit.Testing

Test assertions for the Option, Result and Patch<T> of CodoMetis.TypeKit. None of them 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();

A Patch<T> field of a request says whether the request mentioned it, and the assertions say the same; OrderPatch here has Patch<string> Name, Patch<string> Nickname and Patch<int> Quantity:

OrderPatch patch = JsonSerializer.Deserialize<OrderPatch>("""{"nickname":null,"quantity":2}""", JsonSerializerOptions.Web)!;

int quantity = patch.Quantity.ShouldBeValue();   // the value, handed back
patch.Nickname.ShouldBeNull();                   // a clear
patch.Name.ShouldBeAbsent();                     // not in the document
  • The content comes back. ShouldBeSome(), ShouldBeSuccess(), ShouldBeError() and ShouldBeValue() 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 prints the error through its ToString(), which is what a test needs to see, so an exception's message or a Fault's detail appears; it never prints a value, as Option, Result and Patch<T> themselves never do.
  • An uninitialized result fails every assertion, saying it is a default instance, neither a success nor an error.
