This is a port of QUnit unit testing framework to nodejs
http://github.com/jquery/qunit
Features
- the simplest API of the world, especially for asynchronous testing
- you can write tests in TDD or BDD style depending on your task and test type
- you can run tests in browser if there is no dependencies to node
- you are using the same testing API for client and server side code
- tests inside of one testfile run synchronous, but every testfile runs parallel
- tests from each file run in its own spawned node process
- usage via CLI or testrunner API
- test coverage jscoverage is removed, node-bunker have to be implemented #26
Installation
Using Node Package Manager:
npm install qunit
From git:
git clone https://github.com/kof/node-qunit.git
git submodule init
git submodule update
To install the latest release:
npm install qunit
To install the latest stable release
npm install qunit@stable
API
http://docs.jquery.com/QUnit
Setup
// Add a test to run.
test(name, expected, test)
// Add an asynchronous test to run. The test must include a call to start().
asyncTest(name, expected, test)
// Specify how many assertions are expected to run within a test.
expect(amount);
// Separate tests into modules.
module(name, lifecycle)
Assertions
// A boolean assertion, equivalent to JUnit's assertTrue. Passes if the first argument is truthy.
ok(state, message)
// A comparison assertion, equivalent to JUnit's assertEquals. Uses "==".
equal(actual, expected, message)
// A comparison assertion. Uses "===".
strictEqual(actual, expected, message)
// A deep recursive comparison assertion, working on primitive types, arrays and objects.
same(actual, expected, message)
// Assertion to test if a callback throws an exception when run.
raises(actual, message)
Asynchronous Testing
// Start running tests again after the testrunner was stopped.
start()
// Stop the testrunner to wait to async tests to run. Call start() to continue.
stop(timeout)
Usage
Command line
Read full cli api doc using "--help" or "-h":
$ qunit -h
$ qunit -c ./code.js -t ./tests.js
By default, code and dependencies are added to the global scope. To specify
requiring them into a namespace object, prefix the path or module name with the
variable name to be used for the namespace object, followed by a colon:
$ qunit -c code:./code.js -d utils:utilmodule -r ./time.js
via api
var testrunner = require("qunit");
Defaults:
{
// logging options
log: {
// log assertions overview
assertions: true,
// log expected and actual values for failed tests
errors: true,
// log tests overview
tests: true,
// log summary
summary: true,
// log global summary (all files)
globalSummary: true,
},
// run test coverage tool
coverage: false,
// define dependencies, which are required then before code
deps: null,
// define namespace your code will be attached to on global['your namespace']
namespace: null
}
// change any option for all tests globally
testrunner.options.optionName = value;
// one code and tests file
testrunner.run({
code: "/path/to/your/code.js",
tests: "/path/to/your/tests.js"
}, callback);
// require code into a namespace object, rather than globally
testrunner.run({
code: {path: "/path/to/your/code.js", namespace: "code"},
tests: "/path/to/your/tests.js"
}, callback);
// one code and multiple tests file
testrunner.run({
code: "/path/to/your/code.js",
tests: ["/path/to/your/tests.js", "/path/to/your/tests1.js"]
}, callback);
// array of code and test files
testrunner.run([
{
code: "/path/to/your/code.js",
tests: "/path/to/your/tests.js"
},
{
code: "/path/to/your/code.js",
tests: "/path/to/your/tests.js"
}
], callback);
// using testrunner callback
testrunner.run({
code: "/path/to/your/code.js",
tests: "/path/to/your/tests.js"
}, function(err, report) {
console.dir(report);
});
// specify dependency
testrunner.run({
deps: "/path/to/your/dependency.js",
code: "/path/to/your/code.js",
tests: "/path/to/your/tests.js"
}, callback);
// dependencies can be modules or files
testrunner.run({
deps: "modulename",
code: "/path/to/your/code.js",
tests: "/path/to/your/tests.js"
}, callback);
// dependencies can required into a namespace object
testrunner.run({
deps: {path: "utilmodule", namespace: "utils"},
code: "/path/to/your/code.js",
tests: "/path/to/your/tests.js"
}, callback);
// specify multiple dependencies
testrunner.run({
deps: ["/path/to/your/dependency1.js", "/path/to/your/dependency2.js"],
code: "/path/to/your/code.js",
tests: "/path/to/your/tests.js"
}, callback);
Writing tests
QUnit API and code which have to be tested are already loaded and attached to the global context.
Because nodejs modules reserved "module" namespace we have to redefine it from QUnit namespace.
module = QUnit.module;
Basically QUnit API can ba accessed directly from global object or optional via "QUnit" object.
QUnit.test;
Some tests examples
test("a basic test example", function() {
ok(true, "this test is fine");
var value = "hello";
equals("hello", value, "We expect value to be hello");
});
module("Module A");
test("first test within module", 1, function() {
ok(true, "all pass");
});
test("second test within module", 2, function() {
ok(true, "all pass");
});
module("Module B", {
setup: function() {
// do some initial stuff before every test for this module
},
teardown: function() {
// do some stuff after every test for this module
}
});
test("some other test", function() {
expect(2);
equals(true, false, "failing test");
equals(true, true, "passing test");
});
module("Module C", {
setup: function() {
// setup a shared environment for each test
this.options = {test: 123};
}
});
test("this test is using shared environment", 1, function() {
same({test:123}, this.options, "passing test");
});
test("this is an async test example", function() {
expect(2);
stop();
setTimeout(function() {
ok(true, "finished async test");
strictEqual(true, true, "Strict equal assertion uses ===");
start();
}, 100);
});
Run tests
$ make test
Coverage
Jscoverage is removed due to a lot of installation problems and bad api,
node-bunker is planned to use but not implemented yet.
