Azure functions integration testing locally - azure

Question

I am trying to run integration tests on an azure functions project locally. My method is to start the azure server programatically using a process. This does not work for some reason.
This is how i setup the process:
private Process process;
private RestClient client;
[OneTimeSetUp]
public void OneTimeSetUp()
{
const string dotnetExePath = #"C:\Program Files\dotnet\dotnet.exe";
const string functionHostPath = #"C:\Users\MyName\AppData\Local\AzureFunctionsTools\Releases\2.24.0\cli\func.dll";
const string functionAppFolder = #"C:\Users\MyName\Source\Repos\ShyftApi\ShyftApi\bin\Debug\netstandard2.0";
process = new Process
{
StartInfo =
{
FileName = dotnetExePath,
Arguments = $"\"{functionHostPath}\" start -p {7001}",
WorkingDirectory = functionAppFolder
}
};
bool success = process.Start();
Assert.AreEqual(true, success);
client = new RestClient($"http://localhost:{7001}/api");
Thread.Sleep(8000);
}
OneTimeSetup succeeds without an error so i assume that the process started correctly (but i see no azure shell, wierd?)
I run a simple http call (using restsharp):
[Test]
public void SimpleTest()
{
RestRequest request = new RestRequest("/test", Method.POST);
IRestResponse response = client.Execute(request);
Assert.AreEqual(200, response.StatusCode);
}
This is the azure function that i am trying to test:
[FunctionName("test")]
public static IActionResult Test([HttpTrigger(AuthorizationLevel.Anonymous, "get", Route = null)]HttpRequest req, TraceWriter log)
{
return new OkObjectResult("ok");
}
The test fails because response.StatusCode is 0 so i assume that the server is not up.
I followed the format used in https://blog.kloud.com.au/2018/11/08/integration-testing-precompiled-v2-azure-functions/ for the arguments to the process. I have manually checked that the paths are correct (But the process starts sucessfully so i dont think the paths are the issue?).
The endpoint i am trying to hit is http://localhost:7071/api/test and when running the azure server regurarly (F5) and accessing it through my browser i get a 200 ok.
What do you think could be the issue? The starting arguments to the process or am i just using the wrong url?

I got it to work now:
private Process process;
private RestClient client;
[OneTimeSetUp]
public void OneTimeSetUp()
{
//Path to azure cli:
const string functionHostPath = #"C:\Users\MyName\AppData\Local\AzureFunctionsTools\Releases\2.24.0\cli\func.exe";
//Path to project build location:
const string functionAppFolder = #"C:\Users\MyName\Source\Repos\ShyftApi\ShyftApi\bin\Debug\netstandard2.0";
int port = 7001;
process = new Process
{
StartInfo =
{
FileName = functionHostPath,
Arguments = $"start -p {port}",
WorkingDirectory = functionAppFolder
}
};
bool success = process.Start();
Assert.AreEqual(true, success);
client = new RestClient($"http://localhost:{port}/api");
Thread.Sleep(5000); //Wait for server to initialize
}
[OneTimeTearDown]
public void OneTimeTearDown()
{
process.CloseMainWindow();
process.Dispose();
}
[Test]
public void SimpleTest()
{
RestRequest request = new RestRequest("test", Method.GET);
IRestResponse response = client.Execute(request);
Assert.AreEqual(HttpStatusCode.OK, response.StatusCode);
}
