DESCRIPTION

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.

Quiz Time• What is the wolf that can huff and puff your hay stack in

your test pyramid?

• What is the wolf that can break your wooden stack in your test pyramid?

• Who is the wolf that can break you brick stack in your test pyramid?

• What is the moral of the story? Just build unit tests???

Page-Object Littered With Assertions

www.unicomlearning.com

24

Page 25: Agile Test Automation Anti-patterns and Rescue Strategies

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

25

Page 26: Agile Test Automation Anti-patterns and Rescue Strategies

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

www.unicomlearning.com

Page 28: Agile Test Automation Anti-patterns and Rescue Strategies

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

28

Page 29: Agile Test Automation Anti-patterns and Rescue Strategies

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???
