Fork of speclj by Jeff Terrell to add tools.deps support. Here's an example alias to add to your deps.edn file:

{
 ,,,
 :aliases
 {,,,
  :speclj {:extra-deps {kyptin/speclj
                        {:git/url "https://github.com/kyptin/speclj"
                         :sha "<find the latest sha at that ^^ URL>"}}
         :extra-paths ["spec" "classes"]}
  :test {:main-opts ["-m" "speclj.cli"]}
 }
}

Also, before first use, you must:

mkdir classes
clojure -M:speclj -e "(do (compile 'speclj.platform.SpecFailure)
                          (compile 'speclj.platform.SpecPending))"

With both of those completed, to run tests, say:

clojure -M:speclj:test

The upstream README follows.

speclj

(pronounced "speckle" [spek-uhl])

It's a TDD/BDD framework for Clojure and Clojurescript, based on RSpec.

Installation | Clojure | ClojureScript

Installation

NOTE: Speclj 3.3+ requires Clojure 1.7+.

From Scratch

lein new speclj YOUR_PROJECT_NAME

@trptcolin's speclj template will generate all the files you need.

Or, if you're using ClojureScript:

lein new specljs YOUR_PROJECT_NAME

@ecmendenhall's specljs template will save you lots of time by getting you started with a running Clojure & ClojureScript setup.

Using Leiningen (2.0 or later)

Include speclj in your :dev profile :dependencies and:plugins. Then change the :test-paths to "spec"

; - snip
:dependencies [[org.clojure/clojure "1.6.0"]]
:profiles {:dev {:dependencies [[speclj "3.3.0"]]}}
:plugins [[speclj "3.3.0"]]
:test-paths ["spec"]

Manual installation

1. Check out the source code: https://github.com/slagyr/speclj
2. Install it:

$ lein install

Usage

API Documentation

Start with the speclj.core namespace. That is Speclj's API and it's very unlikely you'll need anything else.

Clojure

File Structure

All your speclj code should go into a directory named spec at the root of your project. Conventionally, the spec directory will mirror the src directory structure except that all the spec files will have the '_spec.clj' postfix.

| sample_project
|-- project.clj
|-- src
    |-- sample
        |-- core.clj
        | (All your other source code)
|-- spec
    |-- sample
        |-- core_spec.clj
       	| (All your other test code)

A Sample Spec File

Checkout this example spec file. It would be located at sample_project/spec/sample/core_spec.clj. Below we'll look at it piece by piece.

(ns sample.core-spec
  (:require [speclj.core :refer :all]
            [sample.core :refer :all]))

(describe "Truth"

  (it "is true"
    (should true))

  (it "is not false"
    (should-not false)))

(run-specs)

speclj.core namespace

Your spec files should :require the speclj.core in it's entirety. It's a clean namespace and you're likely going to use all the definitions within it. Don't forget to pull in the library that you're testing as well (sample.core in this case).

(require '[speclj.core :refer :all])
(require '[sample.core :refer :all])

describe

describe is the outermost container for specs. It takes a String name and any number of spec components.

(describe "Truth" ...)

it

it specifies a characteristic of the subject. This is where assertions go. Be sure to provide good names as the first parameter of it calls.

(it "is true" ...)

should and should-not

Assertions. All assertions begin with should. should and should-not are just two of the many assertions available. They both take expressions that they will check for truthy-ness and falsy-ness respectively.

(should ...)
(should-not ...)

run-specs

At the very end of the file is an invocation of (run-specs). This will invoke the specs and print a summary. When running a suite of specs, this call is benign.

(run-specs)

should Variants (Assertions)

There are many ways to make assertions. Check out the API Documentation. Take note of everything that starts with should.

Spec Components

it or characteristics are just one of several spec components allowed in a describe. Others like before, with, around, etc are helpful in keeping your specs clean and dry. The same API Documentation lists the spec component (everything that doesn't start with should).

Running Specs

With Leiningen

Speclj includes a Leiningen task.

$ lein spec <OPTIONS>

Using lein run

Speclj also includes a Clojure main namespace:

$ lein run -m speclj.main <OPTIONS>

As a Java command

And sometimes it's just easier to run a Java command, like from an IDE.

$ java -cp <...> speclj.main <OPTIONS>
$ java -cp `lein classpath` speclj.main

Autotest

The -a options invokes the "vigilant" auto-runner. This command will run all your specs, and then wait. When you save any test(ed) code, it will run all the affected specs, and wait again. It's HIGHLY recommended.

$ lein spec -a

Options

There are several options for the runners. Use the --help options to see them all.

$ lein spec --help

:eval-in

When using lein spec you can get a little faster startup by adding :speclj-eval-in :leiningen to your project map. It will prevent Leiningen from spinning up another Java process and instead run the specs in Leiningen's process. Use at your own risk.

ClojureScript

File Structure

All your speclj code should go into a a directory named spec at the root of your project. Conventionally, the spec directory will mirror the src directory structure except that all the spec files will have the '_spec.cljs' postfix.

| sample_project
|-- project.clj
|-- bin
    |-- speclj.js
|-- src
    |-- cljs
    	|-- sample
        	|-- core.cljs
        	| (All your other source code)
|-- spec
    |-- cljs
    	|-- sample
        	|-- core_spec.cljs
       		| (All your other test code)

1. Configure Your project.clj File

lein-cljsbuild is a Leiningen plugin that'll get you up and running with ClojureScript. You'll need to add a :cljsbuild configuration map to your project.clj.

:plugins [[lein-cljsbuild "1.0.3"]]
:cljsbuild {:builds        {:dev  {:source-paths ["src/cljs" "spec/cljs"]
                                   :compiler     {:output-to "path/to/compiled.js"}
                                   :notify-command ["phantomjs" "bin/speclj" "path/to/compiled.js"]}
                            :prod {:source-paths  ["src/cljs"]
                                   :compiler      {:output-to "path/to/prod.js"
                                                   :optimizations :simple}}}
            :test-commands {"test" ["phantomjs"  "bin/speclj" "path/to/compiled.js"]}}

Speclj works by operating on your compiled ClojureScript. The :notify-command will execute the bin/speclj command after your cljs is compiled. The bin/speclj command will use speclj to evaluate your compiled ClojureScript.

2. Create test runner executable

Create a file named speclj in your bin directory and copy the code below:

#! /usr/bin/env phantomjs

var fs = require("fs");
var p = require('webpage').create();
var sys = require('system');

p.onConsoleMessage = function (x) {
    fs.write("/dev/stdout", x, "w");
};

p.injectJs(phantom.args[0]);

var result = p.evaluate(function () {
  speclj.run.standard.armed = true;
  return speclj.run.standard.run_specs(
     cljs.core.keyword("color"), true
  );
});

phantom.exit(result);

A Sample Spec File

Checkout this example spec file. It would be located at sample_project/spec/cljs/sample/core_spec.cljs. Below we'll look at it piece by piece.

(ns sample.core-spec
  (:require-macros [speclj.core :refer [describe it should should-not run-specs]])
  (:require [speclj.core]
            [sample.core :as my-core]))

(describe "Truth"

  (it "is true"
    (should true))

  (it "is not false"
    (should-not false)))

(run-specs)

speclj.core namespace

You'll need to :require-macros the speclj.core namespace and :refer each speclj test word that you want to use. In the example below, we are using describe, it, should, should-not, and run-spec. Yes, this is unfortunate, but unavoidable. If you wanted to use context you would simply add it to the current :refer collection. For a list of speclj test words go to the API Documentation

Your spec files must :require the speclj.core too, even though we don't alias it or refer anything. Don't forget this! It loads all the needed speclj namespaces. Also pull in the library that you're testing (sample.core in this case).

As a final note, when requiring your tested namespaces (sample.core in this case), you'll probabaly want to alias it using :as.

(:require-macros [speclj.core :refer [describe it should should-not run-specs])
(:require [speclj.core]
          [sample.core :as my-core]))

Running ClojureScript Specs

With Leiningen

We defer to cljsbuild to run our test command.

$ lein cljsbuild test

Bash

The command below will start a process that will watch the source files and run specs for any updated files.

$ bin/speclj path/to/compiled.js
