Only allow page.save_screenshot if a window exists?-CodePudding

My Capybara tests are designed to call page.save_screenshot if an example fails. This is configured in a config.after(:each) block in my spec_helper.

However, not all of my tests always have a window open. Long story short, some of my tests may make a few requests using rest-client and then pass/fail based on some rspec expectations. When these type of tests fail, a browser window opens because of the call to page.save_screenshot.

Is there a way to add a conditional so that saving a screenshot is only attempted when there is a window (headless or non-headless) open?

CodePudding user response：

You can probable do something like

page.save_screenshot if page.current_window.exists?

however the best options would really be to make tests that don't use the browser a different type of test (not system or feature) or add metadata to the test so that metadata can be used to determine whether or not the test uses the browser

# In your tests
it 'does something not using the browser', :no_browser do
   ...
end

# In your spec_helper
config.after(:each) do |example|
  page.save_screenshot unless example.metadata[:no_browser]
end
