我正在尝试将RSpec中的代码拆分为多个文件,以使其看起来更好。当前文件如下所示。
require 'rails_helper'
RSpec.describe Api::MyController do
let(:var1) {}
let(:var2) {}
it 'should calculate some value' do
expect(var1 + var2).to eq('some value')
end
end
现在这就是重构后的样子。
require 'rails_helper'
require_relative './mycontroller/calculation'
RSpec.describe Api::MyController do
let(:var1) {}
let(:var2) {}
include Api::MyController::Calculation
end
这就是Calculation.rb的样子。
module Api::MyController::Calculation
it 'should calculate some value' do
expect(var1 + var2).to eq('some value')
end
end
现在的问题是,当它运行时,它会抱怨var1和var2未定义。
答案 0 :(得分:1)
我相信您正在寻找RSpec的shared examples:
# spec/support/shared_examples/a_calculator.rb
RSpec.shared_examples "a calculator" do
it 'should calculate some value' do
expect(x+y).to eq(result)
end
end
然后将共享的示例包括在以下任意一项中:
include_examples "name" # include the examples in the current context
it_behaves_like "name" # include the examples in a nested context
it_should_behave_like "name" # include the examples in a nested context
matching metadata # include the examples in the current context
您可以通过传递一个块将上下文传递给共享示例:
require 'rails_helper'
require 'support/shared_examples/a_calculator'
RSpec.describe Api::MyController do
it_should_behave_like "a calculator" do
let(:x){ 1 }
let(:y){ 2 }
let(:result){ 3 }
end
end
