在运行单元测试的时候一直报错说：Expected response to be a <2XX: success>, but was a <403: Forbidden>

参考：https://stackoverflow.com/questions/60558045/expected-response-to-be-a-2xx-success-but-was-a-403-forbidden-for-control

单元测试文件：

# test/controllers/cars_controller_test.rb

require 'test_helper'

class CarsControllerTest < ActionDispatch::IntegrationTest
   test "should get index" do
       get cars_url
   assert_response :success
   end
end

在运行单元测试的时候一直报错说：Expected response to be a <2XX: success>, but was a <403: Forbidden>

$ bundle exec rails test test/controllers/cars_controller_test.rb
Run options: --seed 15315

# Running:

Failure:
CarsControllerTest#test_should_get_index [/home/meiyi/workspace/baogongpingtai-pc/test/controllers/cars_controller_test.rb:12]:
Expected response to be a <2XX: success>, but was a <403: Forbidden>

rails test test/controllers/cars_controller_test.rb:10

Finished in 0.161935s, 6.1753 runs/s, 6.1753 assertions/s.
1 runs, 1 assertions, 1 failures, 0 errors, 0 skips

解决方法：

1.在 config/application.rb 文件中，注释/删除任何 config.hosts << "your-hostname>"

# config.hosts << "xxxxxxxx.com"
# config.hosts << "www.xxxxxx.com"

我的 config/application.rb 文件中有两个 config.hosts << "your-hostname>"，所以把他们都注释掉

2. 增加 test/fixtures/managers.yml

manager1:
email: admin@email.com
encrypted_password: xxxxxxxx

3. 打开 test/controllers/cars_controller_test.rb，修改代码：

require 'test_helper'

class CarsControllerTest < ActionDispatch::IntegrationTest
include Devise::Test::IntegrationHelpers
setup do
     @manager = managers(:manager1)
     sign_in @manager
end
test "should get index" do
     get cars_url
     assert_response :success
end
end

修改完上面几步，然后在重新运行单元测试

$ bundle exec rails test test/controllers/cars_controller_test.rb
Run options: --seed 9283

# Running:

Finished in 0.281973s, 3.5464 runs/s, 3.5464 assertions/s.
1 runs, 1 assertions, 0 failures, 0 errors, 0 skips

就发现已经可以了
