agile testing anti-patterns and rescue strategies (version2)
DESCRIPTION
Abstract: A lot of them going by the catchy buzz-words adopt practices and end-up paying a lot of price either in terms of un-sustainability or cost-heavy maintenance. This talk is all about learning the things that go wrong in automation testing strategies. We'll then go on to learn how to go the right way about automation testing. Lastly, how do we recover from the elephantine automation test-suite that is killing the team. We'll learn theory. Reflect on our practices to see where we stand. Finally walk away with techniques for theory meeting practice.TRANSCRIPT

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!!!
