unit-testing - 在 midje 中使用背景重用设置和拆卸

我有许多 midje 事实，它们的设置/拆卸几乎但不完全相同。

(against-background [(before :contents (setup!)) (before :contents (data)) (before :facts (set-access)) (after :contents (teardown!)]
  (facts "about this thing i am testing "
    ; ...
  ))

(against-background [(before :contents (setup!)) (before :contents (data)) (before :facts (set-other-access)) (after :contents (teardown!)]
  (facts "about this other thing i am testing "
    ; ...
  ))

我想将背景包装成可重用且最好可参数化的东西，以便我可以重用它们，但这样做有困难。 Midje 告诉我，除上述之外的任何内容都不是预期的背景形式。

最佳答案

Midje 没有能力执行您所要求的内置功能。如果您愿意，请考虑在此处将其添加为问题:

一个解决方案是创建您自己的宏来执行此操作。 (未经测试)

(defmacro against-my-background [docstring & body]
  `(against-background [(before :contents (setup!))
                        (before :contents (data))
                        (before :facts (set-access))
                        (after :contents (teardown!)]
     (facts ~docstring
       ~@body )))

;; usage
(against-my-background "about this thing i am testing"
  (fact (foo) => :bar)
  (fact (foo) =not=> :baz))
