<blockquote>
Non-overridable members (here: HttpClient.PostAsync) may not be used in setup / verification expressions.

I also tried to mock the HttpClient the same way you did, and I got the same error message.
Non-overridable members (here: HttpClient.PostAsync) may not be used in setup / verification expressions.
I also tried to mock the HttpClient the same way you did, and I got the same error message.
Solution:
Instead of mocking the HttpClient, mock the HttpMessageHandler.
Then give the
<blockquote>
mockHttpMessageHandler.Object
</blockquote>
to your HttpClient, which you then pass to your product code class. This works because HttpClient uses HttpMessageHandler under the hood:
<pre><code>// Arrange
var mockHttpMessageHandler = new Mock&lt;HttpMessageHandler&gt;();
mockHttpMessageHandler.Protected()
 .Setup&lt;Task&lt;HttpResponseMessage&gt;&gt;(&quot;SendAsync&quot;, ItExpr.IsAny&lt;HttpRequestMessage&gt;(), ItExpr.IsAny&lt;CancellationToken&gt;())
 .ReturnsAsync(new HttpResponseMessage { StatusCode = HttpStatusCode.OK });

var client = new HttpClient(mockHttpMessageHandler.Object);
this._iADLS_Operations = new ADLS_Operations(client);
</code></pre>
Note: You will also need a
<pre><code>using Moq.Protected;
</code></pre>
at the top of your test file.
Then you can call your method that uses PostAsync from your test, and PostAsync will return an HTTP status OK response:
<pre><code>var returnedItem = this._iADLS_Operations.MethodThatUsesPostAsync(/*parameter(s) here*/);
</code></pre>
Advantage: Mocking HttpMessageHandler means that you don't need extra classes in your product code or your test code.

After mock arrangements can be verify with

I am very new to Testing. I am trying to understand how can I unit test since I do not really need to actually trigger these services but probably mock every step.
How can I unit test the following piece of code?
<pre><code>public void myFunction()
{
// I am getting an auth token from a service
// then 

 using (HttpClient httpClient = new HttpClient())
 {
 // do a POST call on another service
 var response = httpClient.PostAsync(url, content);
 }

}
</code></pre>

c# unit test httpclient postasync

我对测试很陌生。我正试图理解如何才能进行单元测试，因为我并不真的需要实际触发这些服务，但可能会嘲笑每个步骤。如何对以下代码进行单元测试？public void myFunction(){// I am getting an auth token from a service// then     using (Http...
