Question

I’m a tester working with automation and recently looking into webdriver and I get the idea with pageObjects and how to run tests with Nunit for example.
My problem is that I don’t want to run tests in a predefined order. The GUI-automation solution we currently have uses ModelBasedTesting tool GraphWalker to generate the testsequence at execution and I would like to continue with that approach.

It works like this in short: A graph contains action- and verificationsteps and some logic to determine how to “walk the graph”. Each step represent a method to be executed in webdriver.

I could of course make a lot of methods and call them one by one, but then I would not have the nice support of a testing framework like Nunit or the structure of PageObjects.

What I (think) I would like is:

[TestFixture]
public abstract class LoginTest : TestFixtureBase
{
    [Test]
    public void e_test1()
    {
        loginPage = PageBase.GetInstance<Login>(driver, "Title");                
        accountHome = loginPage.MainLogin(username, password);
        Assert.IsTrue(accountHome.UserLoggedIn(),"fail");
    }
    [Test]
    public void v_test1()
    {
        loginPage = accountHome.LogOut();
        Assert.IsTrue(loginPage.UserLoggedOut(), "Fail");
    }
    .
    .
    .
    [Test]
    public void e_testN()
    {
        //Do something
    }

And then when i run the graph it gives me “e_test2” as a first step and the magic code runs e_test2(). Next step is “v_test1” so that test is executed.
Anyone knows how to do this?

Update:
I’ve tried the TestCaseSource attribute and got it working, but only when it runs the graph prior the test and returns the complete sequence. I’m looking for a way to execute one step at the time “online”.
This works:

    [Test, TestCaseSource("RunModel")]
    public void LoginAndOut(string method)
    {
        object obj = this.GetType().InvokeMember(method, BindingFlags.InvokeMethod | BindingFlags.Instance | BindingFlags.Public, null, this, null);
    }

    public string[] RunModel()
    {
        List<string> methods = new List<string>();
        while (Model.graphWalker.HasNextStep())
        {
            methods.Add(Model.graphWalker.GetNextStep().ToString());
        }
        return methods.ToArray();
    }

But I would like to accomplish something like:

    while (Model.graphWalker.HasNextStep())
        {   //Get next method from GraphWalker Soap-service.
            nextMethodToRun = Model.graphWalker.GetNextStep().ToString());
            //handle Method result, if ok continue.
        }

Gave up on NUnit and found the solution with Gallio/MbUtnit and DynamicTestFactory.
works just as intended.

    [DynamicTestFactory]
    public IEnumerable<Test> LoginAndOut() 
    {
        string method;
        while (Model.graphWalker.HasNextStep())
        {
            method=Model.graphWalker.GetNextStep().ToString();
            if (method == string.Empty)
                break;
            yield return new TestCase(method, () =>
                {
                    object obj = this.GetType().InvokeMember(method, BindingFlags.InvokeMethod | BindingFlags.Instance | BindingFlags.Public, null, this, null);
                });
        }
     }
