我的测试文件中有:

controller.request.stub referer: 'bla'
这将产生弃用警告:

Using `stub` from rspec-mocks' old `:should` syntax without explicitly enabling the syntax is deprecated. Use the new `:expect` syntax or explicitly enable `:should` instead.
控制器规格中设置request.referer的正确方法是什么?提前感谢。

尝试
允许(controller.request)。接收(:referer)。并返回('bla')

正如警告所说,
.stub
语法已被弃用
