正在运行的Rails服务器会更改测试结果吗? [英] Running rails server changes test result?
问题描述
与这个问题有关，我遇到了一个奇怪的情况. ruby on rails-使用RSpec/Capybara登录测试失败/Poltergeist-堆栈溢出
Related with this question, I came across a strange situation. ruby on rails - Log in test fails with RSpec / Capybara / Poltergeist - Stack Overflow
bin/rspec spec/features/spec.rb
11871 spring server | myapp | started 32 secs ago
11877 spring app | myapp | started 31 secs ago | test mode
我从PhantomJS获得日志，如:
I get log from PhantomJS like:
API.ajax:GET /user :failed
httpStatus:0
error
undefined
bin/rails s
接着
bin/rspec spec/features/spec.rb
我从PhantomJS获得日志，如:
I get log from PhantomJS like:
API.ajax:POST /sessions :failed
httpStatus:401
error
[object Object]
如果没有在开发中运行服务器，PhantomJS甚至无法访问/sessions URL. (尽管如此它还是会失败..)
It looks like PhantomJS can't even reach the /sessions url without server running in development. (It fails anyway though..)
有人有相同的经历吗?我不知道为什么运行dev服务器会进行此更改，并希望有一条线索可以解决测试失败.
Does anyone have same experience? I don't know why running dev server makes this change and hope there is a clue to resolve the test failure.
我正在使用RSpec，Cabybara，Poltergeist，PhantomJS 2.0和 React .
I'm using RSpec, Cabybara, Poltergeist, PhantomJS 2.0 and React.
谢谢！
推荐答案
除非您已设置Capybara.server_port，否则开发服务器在端口3000上运行，而Capybara在随机端口上运行测试服务器.从您的描述中听起来，您可能已经引用了对JS的port 3000硬编码的引用，这意味着即使在测试模式下运行，它也不是在尝试与开发服务器联系
The dev server runs on port 3000 while Capybara runs the test server on a random port unless you've set Capybara.server_port. From your description it sounds like you may have a reference to port 3000 hard coded into your JS, which would mean it wasn't it's trying to contact the dev server even when running in test mode
