ruby-on-rails - Rspec Rails 测试错误:失败/错误:JSON.parse(response.body) && JSON::ParserError: 784: '' 处的意外令牌
问题描述
晚上好:
所以我对 Rails 测试的世界是全新的。我一直在关注本关于 API 和身份验证的教程,以尝试学习测试:
Scotch.io - build-a-restful-json-api-with-rails-5
现在本教程适用于 Rails 5(我使用的是 rails 6 - 可能与问题有关?)
所以发生的事情是当我运行rails exec rspec
测试时运行良好,直到我点击我的clients_spec.rb
// 客户端控制器规范 POST 测试的这个块(如下所示):
describe 'Post /loadze_app/api/v1/clients' do
let(:valid_attributes) { { client_name: 'Mega Client', street_address: '221 some address rd' } }
context 'when the request is valid' do
before { post '/loadze_app/api/v1/clients', params: valid_attributes }
it 'creates a client' do
expect(json['client_name']).to eq('Mega Client')
end
it 'returns status code 201' do
expect(response).to have_http_status(201)
end
end
context 'when the request is invalid' do
before { post '/loadze_app/api/v1/clients', params: { street_address: 'Foobar' } }
it 'returns status code 422' do
expect(response).to have_http_status(422)
end
it 'returns a validation failure message' do
expect(response.body).to match(/Validation failed: Client name can't be blank/)
end
end
end
当我删除此块并再次运行测试时,一切正常。所以我有点茫然,努力在 Stack 和其他资源网站上找到任何相关的修复程序。
这是我运行时遇到的错误rails exec rspec
:
1) Clients API Post /loadze_app/api/v1/clients when the request is valid creates a client
Failure/Error: JSON.parse(response.body)
JSON::ParserError:

任何有关此问题的帮助将不胜感激!如果需要更多信息,请告诉我!提前致谢!
解决方案
可能需要更多关于客户正在做什么的上下文,但请尝试:
before { post '/loadze_app/api/v1/clients', params: valid_attributes.to_json, as: :json }
