- MongoDB event export.
- [Admiral](https://github.com/TestArmada/admiral) reporting support.
- Plays well with CI (Jenkins, etc).
- SauceLabs Remote Browser and Device Support:
- Optional Sauce Connect tunnel management (`--create_tunnels`).
- Create lists of browser tiers or browser testing groups with browser profiles (eg: tier1 browsers, tier2 browsers, mobile browsers, vintage IE versions, etc).
- Manage not just browsers, but also devices for native application testing (iOS and Android)
- Runs test over the cloud like saucelabs via magellan executor (configurable and in parallel)
- Can talk to a [locks service](https://github.com/TestArmada/locks) to control saucelabs virtual machine usage (beta).

------------------**BREAKING CHANGE in v10.0.0**------------------
### Magellan Executor

Executor is a mid layer between magellan and test framework to drive test run (via framework) based on a specific need (differentiated by executing environments). Magellan doesn't provide a default executor, so you need to pick at least one executor from the existing executor list, or implement one yourself.

#### What is an executor
1. middle layer between magellan and test framework
2. bridge to connect magellan and plugins

#### What can an executor do
1. resolve profiles (env info, test info, capabilities for selenium test)
2. patch setup and teardown event on the magellan test runner
3. patch setup and teardown event on a magellan worker
4. do some extra work in test's lifecycle
5. communicate to a specific test env

#### Existing executors
* [magellan-local-executor](https://github.com/TestArmada/magellan-local-executor)
* [magellan-saucelabs-executor](https://github.com/TestArmada/magellan-saucelabs-executor)
* [magellan-browserstack-executor](https://github.com/TestArmada/magellan-browserstack-executor)(early beta)


Test Framework Compatibility and Installation
=============================================

Magellan supports test frameworks like Mocha and Nightwatch via the usage of **plugins**.

#### Mocha

Plugin:
- https://github.com/TestArmada/magellan-mocha-plugin

Boilerplate / example projects:
------------------BREAKING CHANGE in v10.0.0------------------

- `wd` ( [example Mocha/wd project](https://github.com/TestArmada/boilerplate-mocha-wd) )
- `webdriver.io` ( [example Mocha/webdriver.io project](https://github.com/TestArmada/boilerplate-mocha-webdriverio) )
- `node.js` test suites - see `magellan`'s own test suite
- `appium.js` - example project coming soon.
magellan@10.0.0 doesn't support the mocha plugin for now. If you're using magellan version 9 or lower to run mocha test please don't upgrade. Or if you're seeking for mocha support please use magellan version 9 or lower.

Installation:

```shell
npm install --save-dev testarmada-magellan
npm install --save-dev testarmada-magellan-mocha-plugin
```

`magellan.json`
```json
{
"framework": "testarmada-magellan-mocha-plugin"
}
```
All magellan mocha supports can be found [here](https://github.com/TestArmada/magellan/blob/v8.8.5/README.md#mocha)

#### Running Many Tests in Parallel (Default)

By default, `magellan` will try to run your test suite the fastest way possible, in parallel, in the `phantomjs` browser.
By default, `magellan` will try to run your test suite the fastest way possible, in parallel

To execute your tests, run:
You can also run parallel tests on a real local browser (with `magellan-local-executor`):
```console
$ magellan
```

You can also run parallel tests on a real local browser:
```console
# launch several instances of Chrome at once and run tests in parallel
$ magellan --browser=chrome
# launch several instances of phantomjs at once and run tests in parallel
$ magellan --local_browser=phantomjs

# launch several instances of Firefox at once and run tests in parallel
$ magellan --browser=firefox
$ magellan --local_browser=firefox
```

#### Testing in Multiple Browsers

`magellan` can run your test suite across multiple browsers with one command:
```console
# Run tests locally in both PhantomJS and Chrome
$ magellan --browser=chrome,phantomjs

# Run tests locally in Chrome and Firefox
$ magellan --browser=chrome,firefox
# Run tests locally in Chrome,phantomjs and Firefox
$ magellan --local_browsers=chrome,firefox,phantomjs
```

#### Controlling Which Tests Run

##### Tag Support in Mocha-based Tests

In Mocha-based tests, Magellan will find tags in `it()` strings in the form of a tagname preceded by an `@`. For example, to define a test that would match with `--tags=commerce` or `--tags=smoke`, we would write:

```javascript
it("should submit the purchase @commerce @smoke", function (done) {
...
});
```

##### Tag Support in Nightwatch.js-based Tests

In Nightwatch-based tests, Magellan supports the standard Nightwatch convention of tags. To define a test that Magellan can match with `--tags=commerce` or `--tags=smoke`, we would write:

Note: Magellan should ensure that `flush()` always runs even if your test suite fails.

SauceLabs Support
=================

Magellan supports running tests through SauceLabs remote browsers. To do this, the following environment variables should be set:

```shell
# Set SauceLabs Credentials
export SAUCE_USERNAME='xxxxxxxxxx'
export SAUCE_ACCESS_KEY='xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx'

# Set Secure Tunnel Settings

# SauceConnect version for download
export SAUCE_CONNECT_VERSION=4.3.10
```

A Sauce Connect tunnel prefix must be set for tunnel management to work when using `--create_tunnels` (see more on this below).

```
# Tunnel id prefix, Example: "my_tunnel", "qa_tunnel", etc
export SAUCE_TUNNEL_ID="xxxxxxxxx"
```

Listing and Using SauceLabs Browsers
====================================

Magellan can query the SauceLabs API for a list of available browsers (for web testing) and devices (for native app testing in iOS and Android), and present them as a list of friendly browser ids:

```console
$ magellan --list_browsers
```

To use a given SauceLabs browser, specify it when using the `--sauce` option:

```console
$ magellan --sauce --browser=chrome_42_Windows_2012_R2_Desktop
```

To use multiple SauceLabs browsers and environments at the same time, simply list multiple ids:
```
$ magellan --sauce --browsers=chrome_42_Windows_2012_R2_Desktop,safari_7_OS_X_10_9_Desktop
```

Note: If you are building reporting or CI tools and want to use the same SauceLabs API and browser naming support toolset, check out [guacamole](https://github.com/TestArmada/guacamole).

SauceLabs Tunnelling Support (Sauce Connect)
============================================

**NOTE**: By default, Magellan assumes that tests run on an open network visible to SauceLabs.

If your tests are running in a closed CI environment not visible to the Internet, a tunnel is required from SauceLabs to your test machine (when using `--sauce` mode). To activate tunnel creation, use `--create_tunnels`. Magellan will create a tunnel for the test run. If you want to distribute your work load across more than one tunnel, specify the `--max_tunnels=N` option, like so:

```console
$ magellan --sauce --browser=chrome_42_Windows_2012_R2_Desktop --create_tunnels --max_tunnels=4 --max_workers=16
```

In the above example, 4 tunnels will be distributed amongst 16 workers.

SauceLabs VM Traffic Control (`locks`)
======================================

To specify a `locks` server, set the environment variable `LOCKS_SERVER`:

```
export LOCKS_SERVER=http://locks.server.example:4765/
```

or use the `--locks_server` option:
```
$ magellan --locks_server=http://locks.server.example:4765 --sauce --browser=chrome_42_Windows_2012_R2_Desktop --create_tunnels --max_tunnels=4 --max_workers=16
```

Display Resolution and Orientation Support (SauceLabs Browsers)
===============================================================

To ensure that the SauceLabs display being used has enough resolution to support a given browser window size, use the `--resolution` option:

Single Sauce browser:
```console
$ magellan --sauce --browser=chrome_42_Windows_2012_R2_Desktop --resolution=1024x768
```

Multiple Sauce browsers:
```console
$ magellan --sauce --browsers=chrome_42_Windows_2012_R2_Desktop,safari_7_OS_X_10_9_Desktop --resolution=1024x768
```

In this case, `1024x768` is selected for `chrome_42_Windows_2012_R2_Desktop` and `safari_7_OS_X_10_9_Desktop`. If this resolution isn't available in all Sauce browser environments specified, Magellan will return an error.

For Sauce devices that support it, orientation is also supported with the `--orientation` option:

```console
$ magellan --sauce --browser=iphone_8_2_iOS_iPhone_Simulator --orientation=landscape
```
Local Browser Profiles
=======================

Sometimes it's useful to specify a list of environments with differing resolutions or orientations. For this case, Magellan supports profiles stored in `magellan.json`:
