ruby - spec 使用不同的配置运行同一组测试

Question

假设一个包含大量测试的规范文件:

before(:all) do
   @object = buildObjectA
end

it 'should compute x correctly' do
   test something based on object
end

it 'should compute y correctly' do
   test something based on object
end

我想做同样的一组测试，但配置不同，例如，在 before(:all) 中，它看起来像这样:

before(:all) do
   @object = buildObjectB
end

这样做的最佳方法是什么？

Answer 1

您可以使用 Shared Examples and Contexts :

RSpec.shared_examples "something" do |x|
  it 'should compute x correctly' do
    test something based on object
  end

  it 'should compute y correctly' do
    test something based on object
  end
end

RSpec.describe "A" do
  include_examples "something", buildObjectA
end

RSpec.describe "B" do
  include_examples "something", buildObjectB
end

(假设你的测试对两个对象都是一样的)
