Mock Call httpWebRequest using XrmFakedContext D365

Hello,

I wanted to mock the call to the HttpWebRequest service web in the unit tests using the XrmFakedContext; in this example I show you the code of the test function and the function that calls the web service Test Class:

[TestMethod, TestCategory("Unit example")]
    public void test()
    { 
    
    //Initialisation
    fakeContext.Initialize(new List()
            {  
                customer,
                 
            });

        
        var inputs = new Dictionary { { "CustomerId", customer.ToEntityReference() }};

        var result = fakeContext.ExecuteCodeActivity(inputs, null);


        Assert.AreEqual(result["Exist"], true);
    }

the function that calls the web service in the customWorkFlow :

private ReponseClass CallServiceWeb(string someParams)
    {
        try
        {

            var request = (HttpWebRequest)WebRequest.Create(someParams);

            request.Method = "GET";
            request.KeepAlive = true;
            request.Accept = @"*/*";

            var credential = new NetworkCredential(someParams, someParams, someParams);
            var credentialCache = new CredentialCache();
            credentialCache.Add(new Uri(url), "NTLM", credential);
            request.Credentials = credentialCache;

            string response = null;

            using (var responseDetail = (HttpWebResponse)request.GetResponse())
            {
                using (var sr = new StreamReader(responseDetail.GetResponseStream()))
                {
                    response = sr.ReadToEnd();
                }
            }

            return this.Deserialize(response);
        }
        catch (Exception e)
        {
            return new ReponseClass () { erreurAppel = e };
        }
    }
