如何解决导入单个库后测试中断
我正在使用clojure新的CLI创建一个项目并运行我所做的测试：
clojure -M:test:runner
这是我的考验
(ns auth.authorize-test
(:require [clojure.test :refer :all]
[auth.authorize :as auth]))
(deftest a-test
(testing "FIXME,I fail."
(is (= 0 0))))
;; this is working good and responding:
;; Ran 1 tests containing 1 assertions.
该项目将从stdin中读取。我的第一步是从文件中获取数据，然后将其写入标准输出以进行测试。因此，我想导入BufferedReader来读取文件：
(ns auth.authorize-test
(:require [clojure.test :refer :all]
[auth.authorize :as auth])
;; I just added this line
(:import (java.io BufferedReader))
(deftest a-test
(testing "FIXME,I fail."
(is (= 0 0))))
;; This is not working and it's returning
;; Ran 0 tests containing 0 assertions.
所以现在不再进行任何测试。
解决方法
最可能的原因是您的代码中存在某种语法错误。
您的代码应为：
(ns auth.authorize-test
(:require [clojure.test :refer :all]
[auth.authorize :as auth])
;; I just added this line
(:import (java.io BufferedReader)))
请注意：三个)在这里结束，而不是您的代码中出现的两个。
这就是我刚刚做的：
(! 734)-> clojure -X:new :name auth.authorize
Generating a project called auth.authorize based on the 'lib' template.
The lib template is intended for library projects,not applications.
(! 735)-> cd auth.authorize/
(! 736)-> vi test/auth/authorize_test.clj
# to change the test to (= 0 0)
(! 737)-> cat test/auth/authorize_test.clj
(ns auth.authorize-test
(:require [clojure.test :refer :all]
[auth.authorize :refer :all]))
(deftest a-test
(testing "FIXME,I fail."
(is (= 0 0))))
(! 738)-> clojure -M:test:runner
Running tests in #{"test"}
Testing auth.authorize-test
Ran 1 tests containing 1 assertions.
0 failures,0 errors.
(! 739)-> vi test/auth/authorize_test.clj
# add in the :import
(! 740)-> cat test/auth/authorize_test.clj
(ns auth.authorize-test
(:require [clojure.test :refer :all]
[auth.authorize :refer :all])
(:import (java.io BufferedReader)))
(deftest a-test
(testing "FIXME,I fail."
(is (= 0 0))))
(! 741)-> clojure -M:test:runner
Running tests in #{"test"}
Testing auth.authorize-test
Ran 1 tests containing 1 assertions.
0 failures,0 errors.
您会看到它可以正确运行测试。
,添加到Sean的答案中，这就是编译器看到的内容：
(ns auth.authorize-test
(:require [clojure.test :refer :all]
[auth.authorize :as auth])
(:import (java.io BufferedReader)) ; should terminate ns form here with another `)` char
; Due to missing `)` above,this whole `deftest` form is inside the 'ns' form
; and is ignored w/o an error msg (you could consider this a compiler defect)
(deftest a-test
(testing "FIXME,I fail."
(is (= 0 0))))
) ; end of ns form - should be after `import` keyword
因此，您发现)行上缺少的:import是导致问题的原因。它导致deftest格式位于ns格式的内部，这没有任何意义，并且是语法错误。我很惊讶编译器对此没有错误，我将其视为编译器错误/缺陷/问题，因为它只是默默地失败，而不是打印某种错误消息。
更新
也许您使用的是Clojure的旧版本？我只是用此配置尝试过：
--------------------------------------
Clojure 1.10.2-alpha1 Java 15
--------------------------------------
我得到一个错误：
Syntax error macroexpanding clojure.core/ns at (tst/demo/core.clj:1:1).

Full report at:

Tests failed.
和/tmp/clojure.....edn文件如下：

因此，看来Clojure的当前版本（使用clojure.spec检查ns表单）确实检测到代码中的错误。
