Testing

What is a skill one could learn to set themselves apart from other entry-level programmers? Testing. ...

We had a testing issue this week when a button’s text save changes! was rendering as SAVE CHANGES!, due to the CSS property text-transform: uppercase. How do you test that? One technique is to use RSpec’s match method, and include case insensitivity with i (explored earlier here): > button_text = "foo" => "foo" > expect(button_text).to match("FOO") RSpec::Expectations::ExpectationNotMetError: expected "foo" to match "FOO" # stuff > expect(button_text).to match(/FOO/i) => true We ultimately hard coded the expectation to match("FOO"), because allowing fOo and FoO seemed too permissive. But it remains an option.

Today I found a way to assert that an edit form’s inputs include a record’s saved data. I think it strikes a good balance between broad and narrow scope. # spec/features/user_edits_kit_spec.rb within 'form' do expect(page).to have_selector("input[value='Default copy.']") end This asserts that some content is inside an input field in the form, rather than just anywhere on the page. You can narrow the scope as needed.
