MSTEST - async Testinitialize guarantee test fail

Question

Just wondering, if anyone thought like this:

This is incorrect design to have async call within TestInitialize, as TestInitialize has to happen befo

Answer 1

Probably the cleanest way to do this is to have TestInitialize start the asynchronous operation, as such:

[TestClass]
public class UnitTestAsync
{
    private Task val = null;

    [TestInitialize]
    public void TestInitializeMethod()
    {
        val = TestInitializeMethodAsync();
    }

    private async Task TestInitializeMethodAsync()
    {
        return await LongRunningMethod();
    }

    private async Task LongRunningMethod()
    {
        await Task.Delay(20);
        return 10;
    }

    [TestMethod]
    public async Task TestMehod2()
    {
        Assert.AreEqual(10, await val);
    }
}
