Question

Hello I want to pass the number of retries dynamically from app.config value.

The app.config has the following line:

Answer 1

A bit of work around, but you can use TestCaseSource attribute to create data driven test that will run numberOfRetries times

[Test, TestCaseSource("GetNum")]
public void Test(int testNum)
{
}

private IEnumerable GetNum
{
    get
    {
        int numberOfRetries = int.Parse(ConfigurationManager.AppSettings["retryTest"]);
        for (int i = 1; i <= numberOfRetries; ++i)
        {
            yield return new TestCaseData(i);
        }
    }
}

In test explorer you will see Test(1), Test(2), Test(3).
