+# Lolex [](http://travis-ci.org/sinonjs/lolex) [](https://www.bithound.io/github/sinonjs/lolex)
+
+JavaScript implementation of the timer APIs; `setTimeout`, `clearTimeout`,
+`setImmediate`, `clearImmediate`, `setInterval` and `clearInterval`, along with
+a clock instance that controls the flow of time. Lolex also provides a `Date`
+implementation that gets its time from the clock.
+
+Lolex can be used to simulate passing time in automated tests and other
+situations where you want the scheduling semantics, but don't want to actually
+wait. Lolex is extracted from [Sinon.JS](https://github.com/sinonjs/sinon.js).
+
+## Installation
+
+Lolex can be installed using `npm`:
+
+```sh
+npm install lolex
+```
+
+If you want to use Lolex in a browser, you have a few options. Releases are
+hosted on the [sinonjs.org](http://sinonjs.org/download/) website. You can also
+get the node module and build a file for the browser using browserify:
+
+```sh
+npm install lolex
+npm install browserify # If you don't already have it globally installed
+browserify node_modules/lolex/lolex.js
+```
+
+## Usage
+
+To use lolex, create a new clock, schedule events on it using the timer
+functions and pass time using the `tick` method.
+
+```js
+// In the browser distribution, a global `lolex` is already available
+var lolex = require("lolex");
+var clock = lolex.createClock();
+
+clock.setTimeout(function () {
+ console.log("The poblano is a mild chili pepper originating in the state of Puebla, Mexico.");
+}, 15);
+
+// ...
+
+clock.tick(15);
+```
+
+Upon executing the last line, an interesting fact about the
+[Poblano](http://en.wikipedia.org/wiki/Poblano) will be printed synchronously to
+the screen. If you want to simulate asynchronous behavior, you have to use your
+imagination when calling the various functions.
+
+The `next`, `runAll`, and `runToLast` methods are available to advance the clock. See the
+API Reference for more details.
+
+### Faking the native timers
+
+When using lolex to test timers, you will most likely want to replace the native
+timers such that calling `setTimeout` actually schedules a callback with your
+clock instance, not the browser's internals.
+
+Calling `install` with no arguments achieves this. You can call `uninstall`
+later to restore things as they were again.
+
+```js
+// In the browser distribution, a global `lolex` is already available
+var lolex = require("lolex");
+
+var clock = lolex.install();
+// Equivalent to
+// var clock = lolex.install(typeof global !== "undefined" ? global : window);
+
+setTimeout(fn, 15); // Schedules with clock.setTimeout
+
+clock.uninstall();
+// setTimeout is restored to the native implementation
+```
+
+To hijack timers in another context pass it to the `install` method.
+
+```js
+var lolex = require("lolex");
+var context = {
+ setTimeout: setTimeout // By default context.setTimeout uses the global setTimeout
+}
+var clock = lolex.install(context);
+
+context.setTimeout(fn, 15); // Schedules with clock.setTimeout
+
+clock.uninstall();
+// context.setTimeout is restored to the original implementation
+```
+
+Usually you want to install the timers onto the global object, so call `install`
+without arguments.
+
+## API Reference
+
+### `var clock = lolex.createClock([now[, loopLimit]])`
+
+Creates a clock. The default
+[epoch](https://en.wikipedia.org/wiki/Epoch_%28reference_date%29) is `0`.
+
+The `now` argument may be a number (in milliseconds) or a Date object.
+
+The `loopLimit` argument sets the maximum number of timers that will be run when calling `runAll()` before assuming that we have an infinite loop and throwing an error. The default is `1000`.
+
+### `var clock = lolex.install([context[, now[, toFake[, loopLimit]]]])`
+
+### `var clock = lolex.install([now[, toFake[, loopLimit]]])`
+
+Creates a clock and installs it onto the `context` object, or globally. The
+`now` argument is the same as in `lolex.createClock()`.
+
+`toFake` is an array of the names of the methods that should be faked. You can
+pick from `setTimeout`, `clearTimeout`, `setImmediate`, `clearImmediate`,
+`setInterval`, `clearInterval`, and `Date`. E.g. `lolex.install(["setTimeout",
+"clearTimeout"])`.
+
+The `loopLimit` argument is the same as in `lolex.createClock()`.
+
+### `var id = clock.setTimeout(callback, timeout)`
+
+Schedules the callback to be fired once `timeout` milliseconds have ticked by.
+
+In Node.js `setTimeout` returns a timer object. Lolex will do the same, however
+its `ref()` and `unref()` methods have no effect.
+
+In browsers a timer ID is returned.
+
+### `clock.clearTimeout(id)`
+
+Clears the timer given the ID or timer object, as long as it was created using
+`setTimeout`.
+
+### `var id = clock.setInterval(callback, timeout)`
+
+Schedules the callback to be fired every time `timeout` milliseconds have ticked
+by.
+
+In Node.js `setInterval` returns a timer object. Lolex will do the same, however
+its `ref()` and `unref()` methods have no effect.
+
+In browsers a timer ID is returned.
+
+### `clock.clearInterval(id)`
+
+Clears the timer given the ID or timer object, as long as it was created using
+`setInterval`.
+
+### `var id = clock.setImmediate(callback)`
+
+Schedules the callback, to be fired once `0` milliseconds have ticked by. Note
+that you'll still have to call `clock.tick()` for the callback to fire. If
+called during a tick the callback won't fire until `1` millisecond has ticked
+by.
+
+In Node.js `setImmediate` returns a timer object. Lolex will do the same,
+however its `ref()` and `unref()` methods have no effect.
+
+In browsers a timer ID is returned.
+
+### `clock.clearImmediate(id)`
+
+Clears the timer given the ID or timer object, as long as it was created using
+`setImmediate`.
+
+### `clock.hrtime(prevTime?)`
+Only available in Node.JS, mimicks process.hrtime().
+
+### `clock.tick(time)`
+
+Advance the clock, firing callbacks if necessary. `time` may be the number of
+milliseconds to advance the clock by or a human-readable string. Valid string
+formats are `"08"` for eight seconds, `"01:00"` for one minute and `"02:34:10"`
+for two hours, 34 minutes and ten seconds.
+
+`time` may be negative, which causes the clock to change but won't fire any
+callbacks.
+
+### `clock.next()`
+
+Advances the clock to the the moment of the first scheduled timer, firing it.
+
+### `clock.runAll()`
+
+This runs all pending timers until there are none remaining. If new timers are added while it is executing they will be run as well.
+
+This makes it easier to run asynchronous tests to completion without worrying about the number of timers they use, or the delays in those timers.
+
+It runs a maximum of `loopLimit` times after which it assumes there is an infinite loop of timers and throws an error.
+
+### `clock.runToLast()`
+
+This takes note of the last scheduled timer when it is run, and advances the
+clock to that time firing callbacks as necessary.
+
+If new timers are added while it is executing they will be run only if they
+would occur before this time.
+
+This is useful when you want to run a test to completion, but the test recursively
+sets timers that would cause `runAll` to trigger an infinite loop warning.
+
+### `clock.setSystemTime([now])`
+
+This simulates a user changing the system clock while your program is running.
+It affects the current time but it does not in itself cause e.g. timers to fire;
+they will fire exactly as they would have done without the call to
+setSystemTime().
+
+### `clock.uninstall()`
+
+Restores the original methods on the `context` that was passed to
+`lolex.install`, or the native timers if no `context` was given.
+
+### `Date`
+
+Implements the `Date` object but using the clock to provide the correct time.
+
+## Running tests
+
+Lolex has a comprehensive test suite. If you're thinking of contributing bug
+fixes or suggesting new features, you need to make sure you have not broken any
+tests. You are also expected to add tests for any new behavior.
+
+### On node:
+
+```sh
+npm test
+```
+
+Or, if you prefer more verbose output:
+
+```
+$(npm bin)/mocha ./test/lolex-test.js
+```
+
+### In the browser
+
+[Mochify](https://github.com/mantoni/mochify.js) is used to run the tests in
+PhantomJS. Make sure you have `phantomjs` installed. Then:
+
+```sh
+npm test-headless
+```
