How to run test files in Clojure

Question

I'm using jEdit and what I want to do is to write a file and run tests to it. I'm interested in the process of running the tests, not the files themselves. So I wrote this simple function in `File.clj` ``` (defn abs [n] (if (neg? n) (- n) n)) ``` And this test in `TheTest.clj` ``` (use 'clojure.test) (load-file "File.clj") (deftest sample-test (testing "abs" (is (= 5 (abs (5)))))) (run-tests) ``` and then I run the file `TheTest.clj` but it says: `java.io.FileNotFoundException: File.clj (The system cannot find the file specified) (TheTest.clj:49)` Can someone please tell is this is the way to do the things, and if not how to run the tests :( It's not necessary to be in jEdit, it may be in the command prompt if it should. Also I have leiningen installed and `File.clj` and `TheTest.clj` are in same directory. I also tried providing the whole path to the file in the load-file function but with no success. Thank you very much, good people! :)

Accepted Answer

It's certainly possible to get your example working without Leingingen. It works on my computer with one minor alteration: remove the brackets around `5`, so the test line reads

```
(is (= 5 (abs 5)))
```

To run the script successfully, find the location of your Clojure JAR, open a terminal and switch to the directory where your source files live, then execute the following:

```
java -cp /path/to/clojure/clojure-1.4.0.jar clojure.main TheTest.clj
```

Obviously replace `/path/to/clojure/clojure-1.4.0.jar` with the actual path to Clojure on your system. If you've used Leiningen at all there'll be a copy in your Maven repository (I've got it at `~/.m2/repository/org/clojure/clojure/1.4.0/clojure-1.4.0.jar`)

I've run `TheTest.clj` and the output is:

```
Testing user

Ran 1 tests containing 1 assertions.
0 failures, 0 errors.
