我想重构我的代码,从可能的三行到一行。
以下是片段:
# capture an array of the three stats: impressions/clicks/AVT
stats = page.all('.sub')
# check our array....
expect(stats[0]).to have_content("Impressions")
expect(stats[1]).to have_content("Clicks")
expect(stats[2]).to have_content("Average")
我需要平衡Capybara have_content
和RSpec contain_exactly
。
类似的东西:
expect(stats).to contain_exactly("Impressions", "Clicks", "Average")
结果是:
Failure/Error: expect(stats).to contain_exactly("Impressions", "Clicks", "Average")
expected collection contained: ["Average", "Clicks", "Impressions"]
actual collection contained: [#<Capybara::Element tag="div" path="/html/body/div[2]/div[2]/div/div[1]/div[1]/div[1]">, #<Capybara::Element tag="div" path="/html/body/div[2]/div[2]/div/div[1]/div[2]/div[1]">, #<Capybara::Element tag="div" path="/html/body/div[2]/div[2]/div/div[1]/abbr/div[1]">]
the missing elements were: ["Average", "Clicks", "Impressions"]
the extra elements were: [#<Capybara::Element tag="div" path="/html/body/div[2]/div[2]/div/div[1]/div[1]/div[1]">, #<Capybara::Element tag="div" path="/html/body/div[2]/div[2]/div/div[1]/div[2]/div[1]">, #<Capybara::Element tag="div" path="/html/body/div[2]/div[2]/div/div[1]/abbr/div[1]">]
如何重构这个?

我认为这应该有效:
# capture an array of the three stats: impressions/clicks/AVT
stats = page.all('.sub').map(&:text)
expect(stats).to contain_exactly("Impressions", "Clicks", "Average")

从Rspec 3开始,如果您正在寻找部分匹配,则可以执行以下操作:
expect(stats).to contain_exactly(
a_string_matching(/Impressions/),
a_string_matching(/Clicks/),
a_string_matching(/Average/)
)
