4. What do I mean by Testing ASP.net?

5. WHY? http://www.flickr.com/photos/atomicpuppy/2132073976/

6. It is 2010. Automated testing is no longer controversial.

7. [TestMethod()] public void DebitTest() { string customerName = "Mr. Bryan Walton"; double balance = 11.99; BankAccount target = new BankAccount(customerName, balance); double amount = 11.22; target.Debit(amount); Assert.AreEqual((System.Convert.ToDouble(0.77)), target.Balance, 0.05); // 0.05 is tolerance for floating-point comparison //Assert.Inconclusive("A method that does not return a value cannot be verified."); }

8. [TestMethod()] public void DebitTest() { string customerName = "Mr. Bryan Walton"; double balance = 11.99; BankAccount target = new BankAccount(customerName, balance); double amount = 11.22; target.Debit(amount); Assert.AreEqual((System.Convert.ToDouble(0.77)), target.Balance, 0.05); // 0.05 is tolerance for floating-point comparison //Assert.Inconclusive("A method that does not return a value cannot be verified."); }

9. [Story] public void Should_find_customers_by_name_when_name_matches() { Story story = new Story("List customers by name"); story.AsA("customer support staff") .IWant("to search for customers in a very flexible manner") .SoThat("I can find a customer record and provide meaningful support"); CustomerRepository repo = null; Customer customer = null; story.WithScenario("Find by name") .Given("a set of valid customers", delegate { repo = CreateDummyRepo(); }) .When("I ask for an existing name", "Joe Schmoe", delegate(string name) { customer = repo.FindByName(name); }) .Then("the correct customer is found and returned", delegate {Assert.That(customer.Name, Is.EqualTo("Joe Schmoe"));}); }

10. =()=>

11. [Description] public class Transferring_between_from_account_and_to_account { static Account fromAccount; static Account toAccount; Context before_each =()=> { fromAccount = new Account {Balance = 1m}; toAccount = new Account {Balance = 1m}; }; When the_transfer_is_made =()=> { fromAccount.Transfer(1m, toAccount); }; It should_debit_the_from_account_by_the_amount_transferred =()=> { fromAccount.Balance.ShouldEqual(0m); }; It should_credit_the_to_account_by_the_amount_transferred =()=> { toAccount.Balance.ShouldEqual(2m); }; }

12. [Test]public void WatiNSearchText_SearchWatiN_TextDisplayedOnScreen(){ IE ie = new IE("http://localhost:49992/WatiNSite/"); ie.TextField(Find.ByName("searchText")).TypeText("WatiN"); ie.Button(Find.ByValue("Search")).Click(); bool result = ie.Text.Contains("WatiN"); Assert.IsTrue(result); }

13. You can make C# readable But it’s hard

24. Behaviour Driven Development

25. describe MyObject do it “should do something cool” do end end

26. [TestMethod()] public void DebitTest() { string customerName = "Mr. Bryan Walton"; double balance = 11.99; BankAccount target = new BankAccount(customerName, balance); double amount = 11.22; target.Debit(amount); Assert.AreEqual((System.Convert.ToDouble(0.77)), target.Balance, 0.05); // 0.05 is tolerance for floating-point comparison //Assert.Inconclusive("A method that does not return a value cannot be verified."); }

27. describe BankAccount, “Transactions” do it “can debit pence from an account” docustomer_name = "Mr. Bryan Walton"; current_balance = 1.50; account = BankAccount(customer_name, current_balance).newamount_to_debit = 1.25; account.Debit(amount); account.Balance.should == 0.25 endend

28. describe BankAccount, “Transactions” do before(:each) docurrent_balance = 1.50; @account = BankAccount.new("Mr. Bryan Walton", current_balance) end it “can debit pence from an account” doamount_to_debit = 1.25 @account.Debit amount @account.Balance.should == 0.25 endend

31. Thank you

32. DEMO RSpec

33. Outside-in Development

34. Executable Specification

35. Cucumber http://www.flickr.com/photos/vizzzual-dot-com/2738586453/

36. Feature: Creating a schedule In Order to book meetings The manager Needs to be able to view a teams calendar Scenario: View calendar of another view GivenBob has a public calendar When the manager views Bob’s calendar Then an empty calendar should be shown

37. Given/^([^amp;quot;]*) has a public calendar$/ do |user| end

38. When /^ the manager views ([^amp;quot;]*)’s calendar$/ do |user| end

39. Then /^ an empty calendar should be shown $/ do end

40. [Story] public void Should_find_customers_by_name_when_name_matches() { Story story = new Story("List customers by name"); story.AsA("customer support staff") .IWant("to search for customers in a very flexible manner") .SoThat("I can find a customer record and provide meaningful support"); CustomerRepository repo = null; Customer customer = null; story.WithScenario("Find by name") .Given("a set of valid customers", delegate { repo = CreateDummyRepo(); }) .When("I ask for an existing name", "Joe Schmoe", delegate(string name) { customer = repo.FindByName(name); }) .Then("the correct customer is found and returned", delegate {Assert.That(customer.Name, Is.EqualTo("Joe Schmoe"));}); }

41. Feature: List customers by name As a customer support staff I want to search for customers in a very flexible manner So that I can find a customer record and provide meaningful supportScenario: Find by name Given a set of valid customers When I ask for an existing name Then the correct customer is found and returned

42. NOT BEST PRACTICE!! Given /^a set of valid customers$/ do @repo = CreateDummyRepo()endWhen /^I ask for an existing name$/ do @customer = @repo.FindByName("Joe Schmoe")endThen /^the correct customer is found and returned$/ do @customer.Name.should == "Joe Schmoe“end
