因此,在我的应用程序中,我可以禁用所有测试的缓存,这将是理想的,但显然有许多遗留测试依赖于缓存功能.有没有办法为单个RSpec测试启用Rails缓存？
就像是：
before(:each) do @cache_setting = Rails.cache.null_cache Rails.cache.null_cache = true end after(:each) do Rails.cache.null_cache = @cache_setting end it 'does not hit the cache' do ... end
解决方法
在spec_helper.rb中
RSpec.configure do |config|
config.before(:example,disable_cache: true) do
allow(Rails).to receive(:cache).and_return(ActiveSupport::Cache::NullStore.new)
end
config.after(:example,disable_cache: true) do
allow(Rails).to receive(:cache).and_call_original
end
end
在xxx_spec.rb中
RSpec.describe "a group without matching Metadata" do it "does not run the hook" do puts Rails.cache.class end it "runs the hook for a single example with matching Metadata",disable_cache: true do puts Rails.cache.class end end
