How to test the response code with Capybara + Selenium
提问by deb
I have the following spec:
我有以下规格：
it "deletes post", :js => true do
...
...
page.status_code.should = '404'
end
The page.status_codeline is giving me this error:
该page.status_code行给了我这个错误：
Capybara::NotSupportedByDriverError
How do I check the page's status code?
如何查看页面的状态码？
采纳答案by eugen
status_codeis not currently supported by the Selenium driver. You will need to write a different test to check the response status code.
status_codeSelenium 驱动程序当前不支持。您将需要编写不同的测试来检查响应状态代码。

As an aside. This line
作为旁白。这条线
page.status_code.should = '404'
Should be
应该
page.status_code.should == 404
This worked for me with capybara-webkit.
这对我使用 capybara-webkit 有用。

Either switch to another driver (like rack-test) for that test, or test that the displayed page is the 404 page (should have content 'Not Found' in h1).
要么切换到另一个驱动程序（如rack-test）进行该测试，要么测试显示的页面是 404 页面（在 h1 中应该有内容“未找到”）。
As @eugen said, Selenium doesn't support status codes.
正如@eugen 所说，Selenium 不支持状态代码。

Selenium web driver doest not implement status_code and there is no direct way to test response_code with selenium (developer's choice).
Selenium Web 驱动程序不实现 status_code 并且没有直接的方法用 selenium 测试 response_code（开发人员的选择）。
To test it I added in my layout/application.html.erb:
为了测试它，我在 layout/application.html.erb 中添加了：
<html code="<%= response.try(:code) if defined?(response) %>">[...]</html>
And then in my test:
然后在我的测试中：
def no_error?
response_code = page.first('html')[:code]
assert (response_code == '200'), "Response code should be 200 : got #{response_code}"
end

Try it out
试试看
expect(page).to have_http_status(200)

Use js to make a request and get status as below:
使用 js 发出请求并获取如下状态：
js_script = <<JSS
xhr = new XMLHttpRequest();
xhr.open('GET', '#{src}', true);
xhr.send();
JSS
actual.execute_script(js_script)
status = actual.evaluate_script('xhr.status') # get js variable value
