MSTest: how to increase test time

Question

I have one test that needs to work more then 1 minute (VS2008, MSTest, tests are launched from the VisualStudio):

    const int TestTimeout = 1;

    [TestMethod]
    [Timeout(10*60*1000)] // 10 minutes
    public void Login_ExpirationFail_Test()
    {
        IAuthenticationParameters parameters = new AuthenticationParameters(...);
        LdapAuthentication auth1 = new LdapAuthentication();
        IAuthenticationLoginResult res = auth1.Login(parameters);

        Assert.IsNotNull(res);
        Assert.IsFalse(string.IsNullOrEmpty(res.SessionId));

        const int AdditionalMilisecodns = 400;
        System.Threading.Thread.Sleep((TestTimeout * 1000 + AdditionalMilisecodns) * 60);

        LdapAuthentication auth2 = new LdapAuthentication();
        auth2.CheckTicket(res.SessionId);
    }

This test is finished in "Run" mode with "Test 'Login_ExpirationFail_Test' exceeded execution timeout period." error message, in "Debug" - it works fine.

I saw few similar problems linked to launching tests from the command line.

How could I get my test workable in "Run" mode?

Thanks.

Answer 1

Answer is very simple: attribute value should be a constant, not an expression.

Change

[Timeout(10*60*1000)]

to

[Timeout(600000)]

resolved an issue.

EDIT: Comment to the answer brought to my attention a mistake I've done originally in the answer (wrote "60000" as timeout value). In my source code I have 6000000 and that value helped. the answer was corrected recently
