[英]Durable Azure Functions and Integration Tests
I'm trying to test (integration tests) my Azure Durable Function v3 with SpecFlow and MSTest.我正在尝试使用 SpecFlow 和 MSTest 测试(集成测试)我的 Azure Durable Function v3。
Functions are initialized with DI and Startup class:使用 DI 和 Startup class 初始化函数:
[assembly: FunctionsStartup(typeof(Startup))]
namespace MyNamespace.Functions
{
public class Startup : FunctionsStartup
{
public override void Configure(IFunctionsHostBuilder builder)
{
ConfigureServices(builder.Services);
}
...
Orchestrator entry point is triggered by HTTP endpoint: Orchestrator 入口点由 HTTP 端点触发:
public class Function1
{
[FunctionName(nameof(Function1))]
public async Task<IActionResult> DoYourJob(
[HttpTrigger(AuthorizationLevel.Anonymous, methods: "post", Route = "api/routes/function1")] HttpRequestMessage httpRequest,
[DurableClient] IDurableOrchestrationClient starter)
{
...
My IntegrationTest constructor initializes Az Function with HostBuilder
(thanks to this article ):我的 IntegrationTest 构造函数使用 HostBuilder 初始化 Az
HostBuilder
(感谢这篇文章):
[Binding]
public sealed class Function1StepDefinitions
{
private readonly IHost _host;
private readonly Function1 _function;
public Function1StepDefinitions()
{
var startup = new MyNamespace.Functions.Startup();
_host = new HostBuilder()
.ConfigureWebJobs(config =>
{
config.AddDurableTask(options =>
{
options.HubName = "MyTaskHub";
});
startup.Configure(config);
})
.ConfigureServices(ReplaceTestOverrides) // Method to replace/mock some external services
.Build();
_function = new Function1(Host.Services.GetRequiredService<IOptions..., ..);
And in my test I dont know how to retrieve IDurableOrchestrationClient
to call my HTTP Trigger:在我的测试中,我不知道如何检索
IDurableOrchestrationClient
来调用我的 HTTP 触发器:
[When(@"I call my function")]
public async Task WhenICallMyFunction()
{
var request = new HttpRequestMessage();
await _function.DoYourJob(
request,
Host.Services.GetService<IDurableOrchestrationClient>()); // This is always null
...
Is there a way to retrieve this IDurableOrchestrationClient
and test my whole Function (with Orchestrator and Activities calls)?有没有办法检索这个
IDurableOrchestrationClient
并测试我的整个 Function(使用 Orchestrator 和活动调用)?
Looks like there is a IDurableClientFactory
that you can inject instead based on this code .看起来有一个
IDurableClientFactory
可以根据此代码注入。
Using this, you can create a client to use as shown in this sample .使用它,您可以创建一个要使用的客户端,如本示例中所示。
