规范文件加载顺序问题：在“find_and_eval_shared”中：找不到共享示例

Question

我目前正在研究 Rails 4 测试处方 并且运行我的规范文件的加载顺序存在问题'书中没有提到。不幸的是，我无法从我能找到的问题中解决这个问题。尝试运行我的测试时得到的输出是

Answer 1

在您的 task_spec.rb

中加载共享示例声明文件 size_group.rb

像这样：

require 'support/size_group'

编辑：

最好将 shared_example 主要示例加载到 rails_helper.rb。

规范文件加载顺序问题：在“find_and_eval_shared”中：找不到共享示例

Issues with spec files load order: in `find_and_eval_shared': Could not find shared examples

testing

rspec
