Unit Tests for Sample Data

In this program, the team seeds sample data to use for an automated test framework. I helped with some of unit tests, verifying that the test data created fits the requirments of the framework that uses it. Below are the two unit tests I created that I am most proud of. I used MSDN and several online resources to put together some regular expressions that help verify the sample SSN and email addresses generated by the program.

    [TestMethod]
    public void NewPersonHasValidPhoneNumberTest()
    {
        // Create an initial session state and add the command to it. 
        var initialSessionState = InitialSessionState.CreateDefault2();
        var commandEntry = new SessionStateCmdletEntry("New-RandomPerson", typeof(NewRandomPersonCommand), null);
        initialSessionState.Commands.Add(commandEntry);

        var runspace = RunspaceFactory.CreateRunspace(initialSessionState);

        runspace.Open();

        using (var powershell = PowerShell.Create(initialSessionState))
        {
            powershell.Runspace = runspace;
            powershell.AddCommand("New-RandomPerson");

            var returnedStrings = powershell.Invoke<string>();
            Assert.IsNotNull(returnedStrings);
            Assert.AreEqual(1, returnedStrings.Count);
            var jsonString = returnedStrings[0];
            Assert.IsFalse(string.IsNullOrEmpty(jsonString));

            var person = JsonConvert.DeserializeObject<PersonalInformation>(jsonString);
            Assert.IsNotNull(person);

            var thisPersonPhoneNumber = person.PhoneNumber;

            Assert.IsNotNull(thisPersonPhoneNumber);
            Assert.AreNotEqual("", thisPersonPhoneNumber);
            Assert.IsTrue(typeof(String).IsInstanceOfType(thisPersonPhoneNumber));
            Assert.IsTrue(thisPersonPhoneNumber.Length == 12);
            Assert.IsTrue(Regex.IsMatch(thisPersonPhoneNumber, @"^\d\s\d{10}$"));

        }

        runspace.Close();
    }


    [TestMethod]
    public void NewPersonHasValidEmailTest()
    {
        // Create an initial session state and add the command to it. 
        var initialSessionState = InitialSessionState.CreateDefault2();
        var commandEntry = new SessionStateCmdletEntry("New-RandomPerson", typeof(NewRandomPersonCommand), null);
        initialSessionState.Commands.Add(commandEntry);

        var runspace = RunspaceFactory.CreateRunspace(initialSessionState);

        runspace.Open();

        using (var powershell = PowerShell.Create(initialSessionState))
        {
            powershell.Runspace = runspace;
            powershell.AddCommand("New-RandomPerson");

            var returnedStrings = powershell.Invoke<string>();
            Assert.IsNotNull(returnedStrings);
            Assert.AreEqual(1, returnedStrings.Count);
            var jsonString = returnedStrings[0];
            Assert.IsFalse(string.IsNullOrEmpty(jsonString));

            var person = JsonConvert.DeserializeObject<PersonalInformation>(jsonString);
            Assert.IsNotNull(person);

            var thisPersonEmail = person.EmailAddress;

            Assert.IsNotNull(thisPersonEmail);
            Assert.AreNotEqual("", thisPersonEmail);
            Assert.IsTrue(typeof(String).IsInstanceOfType(thisPersonEmail));
            Assert.IsTrue(Regex.IsMatch(thisPersonEmail, @"^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,63}$", 
                    RegexOptions.IgnoreCase));

        }

        runspace.Close();
    }
