The Big Things That Go Wrong!

It’s So SCARY!!!

• Nothing in life is to be feared, it is only to be understood. -- Marie Curie– You’re not afraid to try again, you’re just afraid of

getting hurt.

• In Everyday Scripting with Ruby, Brian Marick advises to learn to program by writing one. #FailProof

• Learn By Doing

Quiz: Guess the reason for this!

The Details That Go Awry!

I Love Se IDE

X-Path Rocks

Where’re The Page Objects?

Page-Object Littered With Assertions

Bad Code#my_target_page.rbdef verify_edit_link_presence //BAD: Assertion in Page-Object has_link?("Edit").should be_true end

#my_target_specit "blah blah blah" @my_target_page.do_some_action @my_target_page.verify_edit_link_presenceend

Good Code#my_target_page.rbdef has_edit_link? has_link?("Edit")end

 #my_target_specit "blah blah blah" @my_target_page.do_some_action @my_target_page.has_edit_link?.should be_trueend

I love to sleep

Scenario To Code: Good Versus BadAs a userI should be able to add notes to the tableso 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 resultsend

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 endend

Why measure exactness???

Duplication makes life easy

Long live dead code!!!
