在 clojure.test 中有一个允许同时测试多个设备的宏: are
.
在 clojure.test 中,可以结合 are
宏与 testing
?
IE。就像是:
(are [scenario expected input]
(testing scenario
(= expected (my-fn input)))
"scenario 1 - replaces -out by -in" "abc-out" "abc-in")
最佳答案
这是不可能的 are
在 clojure.test..
我调整了 Stuart Sierra 的 are
支持testing
的场景和失败消息如下:
(defmacro my-are
[scenario fail-msg argv expr & args]
(if (or
(and (empty? argv) (empty? args))
(and (pos? (count argv))
(pos? (count args))
(zero? (mod (count args) (count argv)))))
`(testing ~scenario
(clojure.template/do-template ~argv (is ~expr ~fail-msg) ~@args))
(throw (IllegalArgumentException. "The number of args doesn't match are's argv."))))
现在测试被包裹在
testing
中添加了场景和失败消息。这个宏可以这样使用:
(deftest my-test
(my-are "Scenario 1: testing arithmetic" "Testing my stuff failed"
[x y] (= x y)
2 (- 4 1)
4 (* 2 2)
5 (/ 10 2)))
这将导致:
Test Summary
Tested 1 namespaces
Ran 3 assertions, in 1 test functions
1 failures
Results
1 non-passing tests:
Fail in my-test
Scenario 1: testing arithmetic
Testing my stuff failed
expected: (= 2 (- 4 1))
actual: (not (= 2 3))
您可以看到执行了三个断言,失败消息(“测试我的东西失败)显示为失败的测试,并且场景消息(“场景 1:测试算法”)是可见的。
