# File actionpack/lib/action_dispatch/testing/assertions/response.rb, line 77
def assert_in_body(text)
  assert_match(/#{Regexp.escape(text)}/, @response.body)
end

assert_not_in_body(text)

断言给定的 text 不出现在响应正文的任何位置。

# File actionpack/lib/action_dispatch/testing/assertions/response.rb, line 84
def assert_not_in_body(text)
  assert_no_match(/#{Regexp.escape(text)}/, @response.body)
end

assert_redirected_to(url_options = {}, options = {}, message = nil)

断言响应重定向到一个与给定选项匹配的 URL。

# Asserts that the redirection was to the "index" action on the WeblogController
assert_redirected_to controller: "weblog", action: "index"

# Asserts that the redirection was to the named route login_url
assert_redirected_to login_url

# Asserts that the redirection was to the URL for @customer
assert_redirected_to @customer

# Asserts that the redirection matches the regular expression
assert_redirected_to %r(\Ahttp://example.org)

# Asserts that the redirection has the HTTP status code 301 (Moved
# Permanently).
assert_redirected_to "/some/path", status: :moved_permanently

# File actionpack/lib/action_dispatch/testing/assertions/response.rb, line 60
def assert_redirected_to(url_options = {}, options = {}, message = nil)
  options, message = {}, options unless options.is_a?(Hash)

  status = options[:status] || :redirect
  assert_response(status, message)
  return true if url_options === @response.location

  redirect_is       = normalize_argument_to_redirection(@response.location)
  redirect_expected = normalize_argument_to_redirection(url_options)

  message ||= "Expected response to be a redirect to <#{redirect_expected}> but was a redirect to <#{redirect_is}>"
  assert_operator redirect_expected, :===, redirect_is, message
end

assert_response(type, message = nil)

断言响应是以下类型之一

  • :success - 状态码在 200-299 范围内

  • :redirect - 状态码在 300-399 范围内

  • :missing - 状态码为 404

  • :error - 状态码在 500-599 范围内

您也可以传递一个明确的状态码，例如 assert_response(501)，或者它的符号等价形式 assert_response(:not_implemented)。请参阅 Rack::Utils::SYMBOL_TO_STATUS_CODE 获取完整列表。

# Asserts that the response was a redirection
assert_response :redirect

# Asserts that the response code was status code 401 (unauthorized)
assert_response 401

def assert_response(type, message = nil)
  message ||= generate_response_message(type)

  if RESPONSE_PREDICATES.key?(type)
    assert @response.public_send(RESPONSE_PREDICATES[type]), message
  else
    assert_equal AssertionResponse.new(type).code, @response.response_code, message
