具有多个断言的Clojure测试 [英] Clojure test with multiple assertions

问题描述

我开始学习如何为Clojure程序编写测试.我有一个包含多个断言的测试(对 is 的调用).我希望测试在第一个断言失败后立即停止运行.这是我的测试:

I am starting to learn how to write tests for my Clojure program. I have a test with multiple assertions (calls to is). I want the test to stop running as soon as the first assertion fails. Here is my test:

(deftest register-one-command
  (testing "Register-one-command"
    (do
      (is (= 0 (count @test/list-of-commands)))
      (test/add-to-list-of-commands ["A"])
      (is (= 1 (count @test/list-of-commands))))))

如果第一个是失败，我希望整个事情都失败.

If the first is fails, I want the whole thing to fail.

推荐答案

最简单的方法是将不同的测试包装在和

The simplest way is to just wrap the different tests in an and

(deftest register-one-command
  (testing "Register-one-command"
    (is (and
          (= 0 (count @test/list-of-commands))
          (test/add-to-list-of-commands ["A"])
          (= 1 (count @test/list-of-commands))))))

但是，如果可能的话，我会尝试重组测试，以免不必要的额外复杂性.

If possible, however, I would try to restructure the tests so that this extra bit of complexity is unnecessary.
