20. The Details That Go Awry! www.unicomlearning.com
21. I Love Se IDE
22. X-Path Rocks
23. Where’re The Page Objects?
24. Page-Object Littered With Assertions
25. Bad Code #my_target_page.rb def verify_edit_link_presence //BAD: Assertion in Page-Object has_link?("Edit").should be_true end #my_target_spec it "blah blah blah" @my_target_page.do_some_action @my_target_page.verify_edit_link_presence end
26. Good Code #my_target_page.rb def has_edit_link? has_link?("Edit") end #my_target_spec it "blah blah blah" @my_target_page.do_some_action @my_target_page.has_edit_link?.should be_true end
27. I love to sleep
28. Scenario To Code: Good Versus Bad As a user I should be able to add notes to the table so that the information is recorded for future reference. def add_and_save_notes notes fill_in("my_target_text_box", :with => notes) click_button "Save" # This makes an AJAX request and adds new row to the table upon successfully saving sleep(3) #<-- This is BAD code. end def add_and_save_notes notes ... wait_until { has_text?(notes) } #<-- This is GOOD practice that enables test stability and hence faith in test results end
29. Asserting message for exactness • #my_target_spec.rb describe "save notes" do it "should add notes as new row to table upon successful save" do notes = "sample notes" expected_update_message = "Your note is added successfully!" @my_target_page. add_and_save_notes notes @my_target_page.update_message.should == expected_update_message end end Why measure exactness???
30. Duplication makes life easy
31. Long live dead code!!!
