HappyPath.AwesomeAssertions

Fluent assertions for HappyPath Result<T> type using AwesomeAssertions.

Installation

dotnet add package HappyPath.AwesomeAssertions

Usage

BeValid()

Assert that a Result<T> contains a valid value (not an error):

Result<string> result = "hello";

result.Should().BeValid();

BeValid(expected)

Assert that a Result<T> contains a specific value:

Result<string> result = "hello";

result.Should().BeValid("hello", because: "we expect this value");

BeValid(action)

Assert that a Result<T> is valid and perform additional assertions on the value:

Result<User> result = new User("John", 30);

result.Should().BeValid(user =>
{
    user.Name.Should().Be("John");
    user.Age.Should().BeGreaterThan(18);
});

BeError()

Assert that a Result<T> contains an error:

Result<string> result = new Error("Something went wrong");

result.Should().BeError();

BeError().WithMessage(expected)

Assert that a Result<T> contains an error with a specific message:

Result<string> result = new Error("Something went wrong");

result.Should().BeError().WithMessage("Something went wrong");

BeError().OfType<TError>()

Assert that a Result<T> contains an error of an exact type:

Result<string> result = new ValidationError("Invalid input");

result.Should().BeError().OfType<ValidationError>();

BeError().OfType<TError>().WithMessage(expected)

Chain type and message assertions:

Result<string> result = new ValidationError("Invalid input");

result.Should().BeError().OfType<ValidationError>().WithMessage("Invalid input");

BeError(expected)

Assert that a Result<T> contains a specific error:

Result<string> result = new ValidationError("Invalid input");

result.Should().BeError(new ValidationError("Invalid input"));

BeError(action)

Assert that a Result<T> is an error and perform additional assertions:

Result<string> result = new ValidationError("Invalid input");

result.Should().BeError(error =>
{
    error.Should().BeOfType<ValidationError>();
    error.Message.Should().Contain("Invalid");
});
