在测试过程中更改 Rails 环境 [英] change rails environment in the mid of testing

问题描述

测试中如何更改rails的环境变量

How to change the environment variable of rails in testing

推荐答案

You can do

Rails.stub(env: ActiveSupport::StringInquirer.new("production"))

然后 Rails.env、Rails.development? 等将按预期工作.

Then Rails.env, Rails.development? etc will work as expected.

使用 RSpec 3 或更高版本，您可能希望使用新的零猴子修补"语法(如@AnkitG 在另一个答案中提到的)以避免弃用警告:

With RSpec 3 or later you may want to use the new "zero monkeypatching" syntax (as mentioned by @AnkitG in another answer) to avoid deprecation warnings:

allow(Rails).to receive(:env).and_return(ActiveSupport::StringInquirer.new("production"))

我通常在规范帮助器中定义一个 stub_env 方法，这样我就不必将所有这些东西都放在我的测试中.

I usually define a stub_env method in a spec helper so I don't have to put all that stuff inline in my tests.

考虑的选项(如此处的评论中所建议)而是依赖一些更有针对性的配置，您可以在环境文件中设置这些配置并在测试中进行更改.

An option to consider (as suggested in a comment here) is to instead rely on some more targeted configuration that you can set in your environment files and change in tests.
