从Clojure Repl和Leiningen运行测试 [英] Run tests from Clojure Repl and Leiningen

问题描述

作为clojure的新手，我已经使用leiningen创建一个示例项目

As a newbie to clojure, I have used leiningen to create a sample project with

lein new app first-project

这给了我这个目录

.
├── doc
│   └── intro.md
├── LICENSE
├── project.clj
├── README.md
├── resources
├── src
│   └── first_project
│       └── core.clj
├── target
│   └── repl
│       ├── classes
│       └── stale
│           └── extract-native.dependencies
└── test
    └── first_project
        └── core_test.clj

不修改任何文件，我可以成功地唯一失败的测试

Without modifying any files, I can lauch successfully the only failing test with

lein test
...
Ran 1 tests containing 1 assertions.
1 failures, 0 errors.
Tests failed.

但是我无法从REPL使用运行测试执行相同操作

But I am unable to do the same from the REPL using run-tests

lein repl
first-project.core=> (use 'clojure.test)
nil
first-project.core=> (run-tests)

Testing first-project.core

Ran 0 tests containing 0 assertions.
0 failures, 0 errors.
{:type :summary, :pass 0, :test 0, :error 0, :fail 0}

我试过（但不工作）

(require 'first-project.core-test)

推荐答案

在上面的例子中，repl是在错误的命名空间。如果您将repl切换到 core_test 命名空间，它可能会更好。然后运行（run-tests）。

In your example above the repl is in the wrong namespace. It may work better if you switch the repl to the core_test namespace. and then run (run-tests).

(in-ns 'first-project.core-test)
(run-tests)

开发测试的另一个有趣的方法是从REPL运行它们直到他们工作，因为测试是正常的函数，额外元数据。

Another fun way of developing tests is to just run them from the REPL until they work, because tests are normal functions with some extra metadata.

(in-ns 'first-project.core-test)
(my-test)
