.NET API Core 5 集成测试 404

问题描述

我正在尝试使用 NUnit 为我的 .NET 核心 API 创建集成测试项目。

我在尝试 API 调用时收到异常 404。

我为我的测试创建了 FakeStartup 类。如果我的启动，它只是一个副本。

注意：- 如果我通过了我的 IntegrationTestFactory 的 Startup 类，它可以正常工作，没有问题。

私有只读 IntegrationTestFactory factory = new();

public class IntegrationTestFactory<TTestStartup> : WebApplicationFactory<TTestStartup> where TTestStartup : class
    {
        protected override IHostBuilder CreateHostBuilder()
        {
            var host = Host.CreateDefaultBuilder()
                .UseServiceProviderFactory(new AutofacServiceProviderFactory())
                .ConfigureWebHostDefaults(webBuilder =>
                {
                    webBuilder.UseStartup<TTestStartup>();
                    webBuilder.UseEnvironment("Development");
                })
                .UseSerilog((hostingContext,loggerConfiguration) => loggerConfiguration.ReadFrom.Configuration(hostingContext.Configuration));

            return host;
        }
    }

下面是我的测试课

[TestFixture]
public class SimpleIntegrationTests
{
    private readonly IntegrationTestFactory<FakeStartup> factory = new();

    [Test]
    public async Task SimpleTestCase()
    {
        var client = factory.CreateClient();

        // Arrange
        var faker = new Faker();
        var password = $"{faker.Internet.Password(prefix: "TestPassword12@")}$"; //to satisfy the requirement for passwords

        var mockData = new Faker<SaveUserCommand>()
            .RuleFor(u => u.FirstName,f => f.Name.LastName(Name.Gender.Male))
            .RuleFor(u => u.LastName,f => f.Name.LastName(Name.Gender.Male))
            .RuleFor(u => u.EmailAddress,(f,u) => f.Internet.Email(u.FirstName,u.LastName))
            .RuleFor(u => u.MobileNumber,f => f.Phone.PhoneNumberFormat(10))
            .RuleFor(u => u.Password,password)
            .RuleFor(u => u.ConfirmPassword,password)
            .RuleFor(u => u.IsFromregistrationPage,false)
            .RuleFor(u => u.RoleType,f => f.PickRandom<RoleType>())
            .RuleFor(u => u.PurposeType,f => f.PickRandom<PurposeType>());

        var command = mockData.Generate();

        var stringContent = new StringContent(command.ToJson(),Encoding.UTF8,"application/json");
        var response = await client.PostAsync("/api/user",stringContent);
    }
}

解决方法

如果我是对的（很久没有为 API 编写单元测试了）。是您仍然可以像正常测试一样在测试中添加控制器，因此测试看起来像这样。您可以将控制器用于您想要进行的呼叫类型。

[TestFixture]
public class SimpleIntegrationTests
{
    [Test]
    public async Task SimpleTestCase()
    {
        var controller = new yourControllerName(); //You can add the services it needs above (recommend mocking)
        
        // Arrange
        var faker = new Faker();
        var password = $"{faker.Internet.Password(prefix: "TestPassword12@")}$"; //to satisfy the requirement for passwords

        var mockData = new Faker<SaveUserCommand>()
            .RuleFor(u => u.FirstName,f => f.Name.LastName(Name.Gender.Male))
            .RuleFor(u => u.LastName,f => f.Name.LastName(Name.Gender.Male))
            .RuleFor(u => u.EmailAddress,(f,u) => f.Internet.Email(u.FirstName,u.LastName))
            .RuleFor(u => u.MobileNumber,f => f.Phone.PhoneNumberFormat(10))
            .RuleFor(u => u.Password,password)
            .RuleFor(u => u.ConfirmPassword,password)
            .RuleFor(u => u.IsFromRegistrationPage,false)
            .RuleFor(u => u.RoleType,f => f.PickRandom<RoleType>())
            .RuleFor(u => u.PurposeType,f => f.PickRandom<PurposeType>());

        var command = mockData.Generate();

        var stringContent = new StringContent(command.ToJson(),Encoding.UTF8,"application/json");
        var response = controller.Post(stringContent);
    }
}

用记事本写的，这台笔记本电脑上没有编码程序。所以请告诉我它是否有效，或者您是否需要更多帮助。
