单元测试授权处理程序

所有必需的依赖项都可用于独立的单元测试。

所需的试验方法 HandleRequirementAsync 可通过 Task HandleAsync(AuthorizationHandlerContext context)

/// <summary>
/// Makes a decision if authorization is allowed.
/// </summary>
/// <param name="context">The authorization context.</param>
public virtual async Task HandleAsync(AuthorizationHandlerContext context)
{
    if (context.Resource is TResource)
    {
        foreach (var req in context.Requirements.OfType<TRequirement>())
        {
            await HandleRequirementAsync(context, req, (TResource)context.Resource);
        }
    }
}

而那个成员只依赖于 AuthorizationHandlerContext 它有一个构造器,如下所示

public AuthorizationHandlerContext(
    IEnumerable<IAuthorizationRequirement> requirements,
    ClaimsPrincipal user,
    object resource) {

    //... omitted for brevity
}

简单的独立单元测试,用于验证 DocumentAuthorizationHandler .

public async Task DocumentAuthorizationHandler_Should_Succeed() {
    //Arrange    
    var requirements = new [] { new SameAuthorRequirement()};
    var author = "author";
    var user = new ClaimsPrincipal(
                new ClaimsIdentity(
                    new Claim[] {
                        new Claim(ClaimsIdentity.DefaultNameClaimType, author),
                    },
                    "Basic")
                );
    var resource = new Document {
        Author = author
    };
    var context = new AuthorizationHandlerContext(requirements, user, resource);
    var subject = new DocumentAuthorizationHandler();

    //Act
    await subject.HandleAsync(context);

    //Assert
    context.HasSucceeded.Should().BeTrue(); //FluentAssertions
}
