Wait for chromedriver's startup message on stdout

I think this makes more sense then running them via a separate command,
since that command would only make sense for atom-core, unlike the
current 'run-package-specs' command, which works for any atom package.

This way, they won't run by default, but you can opt in to running them
on the command line by setting an env var, or in the spec runner by
temporarily editing the code, like we do for focused tests anyway.

+## Interacting With Other Packages Via Services
+
+Atom packages can interact with each other through versioned APIs called
+*services*. To provide a service, in your `package.json`, specify one or more
+version numbers, each paired with the name of a method on your package's main module:
+
+```json
+{
+  "providedServices": {
+    "my-service": {
+      "description": "Does a useful thing",
+      "versions": {
+        "1.2.3": "provideMyServiceV1",
+        "2.3.4": "provideMyServiceV2",
+      }
+    }
+  }
+}
+```
+
+In your package's main module, implement the methods named above. These methods
+will be called any time a package is activated that consumes their corresponding
+service. They should return a value that implements the service's API.
+
+
+```coffeescript
+module.exports =
+  activate: -> # ...
+
+  provideMyServiceV1: ->
+    adaptToLegacyAPI(myService)
+
+  provideMyServiceV2: ->
+    myService
+```
+
+Similarly, to consume a service, specify one or more [version *ranges*][version-ranges],
+each paired with the name of a method on the package's main module:
+
+```json
+{
+  "consumedServices": {
+    "another-service": {
+      "versions": {
+        "^1.2.3": "consumeAnotherServiceV1",
+        ">=2.3.4 <2.5": "consumeAnotherServiceV2",
+      }
+    }
+  }
+}
+```
+
+These methods will be called any time a package is activated that *provides* their
+corresponding service. They will receive the service object as an argument. You
+will usually need to perform some kind of cleanup in the event that the package
+providing the service is deactivated. To do this, return a `Disposable` from
+your service-consuming method:
+
+```coffeescript
+{Disposable} = require 'atom'
+
+module.exports =
+  activate: -> # ...
+
+  consumeAnotherServiceV1: (service) ->
+    useService(adaptServiceFromLegacyAPI(service))

+# Upgrading your package to 1.0 APIs
+
+Atom is rapidly approaching 1.0. Much of the effort leading up to the 1.0 has been cleaning up APIs in an attempt to future proof, and make a more pleasant experience developing packages.
+
+This document will guide you through the large bits of upgrading your package to work with 1.0 APIs.
+
+## TL;DR
+
+We've set deprecation messages and errors in strategic places to help make sure you don't miss anything. You should be able to get 95% of the way to an updated package just by fixing errors and deprecations. There are a couple of things you can do to get the full effect of all the errors and deprecations.
+
+### Use atom-space-pen-views
+
+If you use any class from `require 'atom'` with a `$` or `View` in the name, add the `atom-space-pen-views` module to your package's `package.json` file's dependencies:
+
+```js
+{
+  "dependencies": {
+    "atom-space-pen-views": "^2.0.3"
+  }
+}
+```
+
+Then run `apm install` in your package directory.
+
+### Require views from atom-space-pen-views
+
+Anywhere you are requiring one of the following from `atom` you need to require them from `atom-space-pen-views` instead.
+
+```coffee
+# require these from 'atom-space-pen-views' rather than 'atom'
+$
+$$
+$$$
+View
+TextEditorView
+ScrollView
+SelectListView
+```
+
+So this:
+
+```coffee
+# Old way
+{$, TextEditorView, View, GitRepository} = require 'atom'
+```
+
+Would be replaced by this:
+
+```coffee
+# New way
+{GitRepository} = require 'atom'
+{$, TextEditorView, View} = require 'atom-space-pen-views'
+```
+
+### Run specs and test your package
+
+You wrote specs, right!? Here's where they shine. Run them with `cmd-shift-P`, and search for `run package specs`. It will show all the deprecation messages and errors.
+
+### Update the engines field in package.json
+
+When you are deprecation free and all done converting, upgrade the `engines` field in your package.json:
+
+```json
+{
+  "engines": {
+    "atom": ">=0.174.0, <2.0.0"
+  }
+}
+```
+
+### Examples
+
+We have upgraded all the core packages. Please see [this issue](https://github.com/atom/atom/issues/4011) for a link to all the upgrade PRs.
+
+## Deprecations
+
+All of the methods in Atom core that have changes will emit deprecation messages when called. These messages are shown in two places: your **package specs**, and in **Deprecation Cop**.
+
+### Specs
+
+Just run your specs, and all the deprecations will be displayed in yellow.
+
+![spec-deps](https://cloud.githubusercontent.com/assets/69169/5637943/b85114ba-95b5-11e4-8681-b81ea8f556d7.png)
+
+### Deprecation Cop
+
+Run an atom window in dev mode (`atom -d`) with your package loaded, and open Deprecation Cop (search for `deprecation` in the command palette). Deprecated methods will be appear in Deprecation Cop only after they have been called.
+
+![dep-cop](https://cloud.githubusercontent.com/assets/69169/5637914/6e702fa2-95b5-11e4-92cc-a236ddacee21.png)
+
+When deprecation cop is open, and deprecated methods are called, a `Refresh` button will appear in the top right of the Deprecation Cop interface. So exercise your package, then come back to Deprecation Cop and click the `Refresh` button.
+
+## Upgrading your Views
+
+Previous to 1.0, views were baked into Atom core. These views were based on jQuery and `space-pen`. They looked something like this:
+
+```coffee
+# The old way: getting views from atom
+{$, TextEditorView, View} = require 'atom'
+
+module.exports =
+class SomeView extends View
+  @content: ->
+    @div class: 'find-and-replace', =>
+      @div class: 'block', =>
+        @subview 'myEditor', new TextEditorView(mini: true)
+  #...
+```
+
+### The New
+
+`require 'atom'` no longer provides view helpers or jQuery. Atom core is now 'view agnostic'. The preexisting view system is available from a new npm package: `atom-space-pen-views`.
+
+`atom-space-pen-views` now provides jQuery, `space-pen` views, and Atom specific views:
+
+
+```coffee
+# These are now provided by atom-space-pen-views
+$
+$$
+$$$
+View
+TextEditorView
+ScrollView
+SelectListView
+```
+
+### Adding the module dependencies
+
+To use the new views, you need to specify the `atom-space-pen-views` module in your package's `package.json` file's dependencies:
+
+```js
+{
+  "dependencies": {
+    "atom-space-pen-views": "^2.0.3"
+  }
+}
+```
+
+`space-pen` bundles jQuery. If you do not need `space-pen` or any of the views, you can require jQuery directly.
+
+```js
+{
+  "dependencies": {
+    "jquery": "^2"
+  }
+}
+```
+
+### Converting your views
+
+Sometimes it is as simple as converting the requires at the top of each view page. I assume you read the 'TL;DR' section and have updated all of your requires.
+
+### Upgrading classes extending any space-pen View
+
+#### `afterAttach` and `beforeRemove` updated
+
+The `afterAttach` and `beforeRemove` hooks have been replaced with
+`attached` and `detached` and the semantics have changed.
+
+`afterAttach` was called whenever the node was attached to another DOM node, even if that parent node wasn't present in the DOM. `afterAttach` also was called with a boolean indicating whether or not the element and its parents were on the DOM. Now the `attached` hook is _only_ called when the node and all of its parents are actually on the DOM, and is not called with a boolean.
+
+`beforeRemove` was only called when `$.fn.remove` was called, which was typically used when the node was completely removed from the DOM. The new `detached` hook is called whenever the DOM node is _detached_, which could happen if the node is being detached for reattachment later. In short, if `beforeRemove` is called the node is never coming back. With `detached` it might be attached again later.
+
+```coffee
+# Old way
+{View} = require 'atom'
+class MyView extends View
+  afterAttach: (onDom) ->
+    #...
+
+  beforeRemove: ->
+    #...
+```
+
+```coffee
+# New way
+{View} = require 'atom-space-pen-views'
+class MyView extends View
+  attached: ->
+    # Always called with the equivalent of @afterAttach(true)!
+    #...
+
+  detached: ->
+    #...
+```
+
+#### `subscribe` and `subscribeToCommand` methods removed
+
+The `subscribe` and `subscribeToCommand` methods have been removed. See the Eventing and Disposables section for more info.
+
+### Upgrading to the new TextEditorView
+
+All of the atom-specific methods available on the `TextEditorView` have been moved to the `TextEditor`, available via `TextEditorView::getModel`. See the [`TextEditorView` docs][TextEditorView] and [`TextEditor` docs][TextEditor] for more info.
+
+### Upgrading classes extending ScrollView
+
+The `ScrollView` has very minor changes.
+
+You can no longer use `@off` to remove default behavior for `core:move-up`, `core:move-down`, etc.
+
+```coffee
+# Old way to turn off default behavior
+class ResultsView extends ScrollView
+  initialize: (@model) ->
+    super()
+    # turn off default scrolling behavior from ScrollView
+    @off 'core:move-up'
+    @off 'core:move-down'
+    @off 'core:move-left'
+    @off 'core:move-right'
+```
+
+```coffee
+# New way to turn off default behavior
+class ResultsView extends ScrollView
+  initialize: (@model) ->
+    disposable = super()
+    # turn off default scrolling behavior from ScrollView
+    disposable.dispose()
+```
+
+* Check out [an example](https://github.com/atom/find-and-replace/pull/311/files#diff-9) from find-and-replace.
+* See the [docs][ScrollView] for all the options.
+
+### Upgrading classes extending SelectListView
+
+Your SelectListView might look something like this:
+
+```coffee
+# Old!
+class CommandPaletteView extends SelectListView
+  initialize: ->
+    super()
+    @addClass('command-palette overlay from-top')
+    atom.workspaceView.command 'command-palette:toggle', => @toggle()
+
+  confirmed: ({name, jQuery}) ->
+    @cancel()
+    # do something with the result

+
+    atom.workspaceView.append(this)
+    @focusFilterEditor()
+
+  confirmed: ({name, jQuery}) ->
+    @cancel()
+```
+
+This attaches and detaches itself from the dom when toggled, canceling magically detaches it from the DOM, and it uses the classes `overlay` and `from-top`.
+
+The new SelectListView no longer automatically detaches itself from the DOM when cancelled. It's up to you to implement whatever cancel beahavior you want. Using the new APIs to mimic the sematics of the old class, it should look like this:
+
+```coffee
+# New!
+class CommandPaletteView extends SelectListView
+  initialize: ->
+    super()
+    # no more need for the `overlay` and `from-top` classes
+    @addClass('command-palette')
+    atom.commands.add 'atom-workspace', 'command-palette:toggle', => @toggle()
+
+  # You need to implement the `cancelled` method and hide.
+  cancelled: ->
+    @hide()
+
+  confirmed: ({name, jQuery}) ->
+    @cancel()
+    # do something with the result
+
+  toggle: ->
+    # Toggling now checks panel visibility,
+    # and hides / shows rather than attaching to / detaching from the DOM.
+    if @panel?.isVisible()
+      @cancel()
+    else
+      @show()
+
+  show: ->
+    # Now you will add your select list as a modal panel to the workspace
+    @panel ?= atom.workspace.addModalPanel(item: this)
+    @panel.show()
+
+    @storeFocusedElement()
+
+    items = [] # TODO: build items
+    @setItems(items)
+
+    @focusFilterEditor()
+
+  hide: ->
+    @panel?.hide()
+```
+
+* And check out the [conversion of CommandPaletteView][selectlistview-example] as a real-world example.
+* See the [SelectListView docs][SelectListView] for all options.
+
+## Using the model layer rather than the view layer
+
+The API no longer exposes any specialized view objects or view classes. `atom.workspaceView`, and all the view classes: `WorkspaceView`, `EditorView`, `PaneView`, etc. have been globally deprecated.
+
+Nearly all of the atom-specific actions performed by the old view objects can now be managed via the model layer. For example, here's adding a panel to the interface using the `atom.workspace` model instead of the `workspaceView`:
+
+```coffee
+# Old!
+div = document.createElement('div')
+atom.workspaceView.appendToTop(div)
+```
+
+```coffee
+# New!
+div = document.createElement('div')
+atom.workspace.addTopPanel(item: div)
+```
+
+For actions that still require the view, such as dispatching commands or munging css classes, you'll access the view via the `atom.views.getView()` method. This will return a subclass of `HTMLElement` rather than a jQuery object or an instance of a deprecated view class (e.g. `WorkspaceView`).
+
+```coffee
+# Old!
+workspaceView = atom.workspaceView
+editorView = workspaceView.getActiveEditorView()
+paneView = editorView.getPaneView()
+```
+
+```coffee
+# New!
+# Generally, just use the models
+workspace = atom.workspace
+editor = workspace.getActiveTextEditor()
+pane = editor.getPane()
+
+# If you need views, get them with `getView`
+workspaceElement = atom.views.getView(atom.workspace)
+editorElement = atom.views.getView(editor)
+paneElement = atom.views.getView(pane)
+```
+
+## Updating Specs
+
+`atom.workspaceView`, the `WorkspaceView` class and the `EditorView` class have been deprecated. These two objects are used heavily throughout specs, mostly to dispatch events and commands. This section will explain how to remove them while still retaining the ability to dispatch events and commands.
+
+### Removing WorkspaceView references
+
+`WorkspaceView` has been deprecated. Everything you could do on the view, you can now do on the `Workspace` model.
+
+Requiring `WorkspaceView` from `atom` and accessing any methods on it will throw a deprecation warning. Many specs lean heavily on `WorkspaceView` to trigger commands and fetch `EditorView` objects.
+
+Your specs might contain something like this:
+
+```coffee
+# Old!
+{WorkspaceView} = require 'atom'
+describe 'FindView', ->
+  beforeEach ->
+    atom.workspaceView = new WorkspaceView()
+```
+
+Instead, we will use the `atom.views.getView()` method. This will return a plain `HTMLElement`, not a `WorkspaceView` or jQuery object.
+
+```coffee
+# New!
+describe 'FindView', ->
+  workspaceElement = null
+  beforeEach ->
+    workspaceElement = atom.views.getView(atom.workspace)
+```
+
+### Attaching the workspace to the DOM
+
+The workspace needs to be attached to the DOM in some cases. For example, view hooks only work (`attached()` on `View`, `attachedCallback()` on custom elements) when there is a descendant attached to the DOM.
+
+You might see this in your specs:
+
+```coffee
+# Old!
+atom.workspaceView.attachToDom()
+```
+
+Change it to:
+
+```coffee
+# New!
+jasmine.attachToDOM(workspaceElement)
+```
+
+### Removing EditorView references
+
+Like `WorkspaceView`, `EditorView` has been deprecated. Everything you needed to do on the view you are now able to do on the `TextEditor` model.
+
+In many cases, you will not even need to get the editor's view anymore. Any of those instances should be updated to use the `TextEditor` instance instead. You should really only need the editor's view when you plan on triggering a command on the view in a spec.
+
+Your specs might contain something like this:
+
+```coffee
+# Old!
+describe 'Something', ->
+  [editorView] = []
+  beforeEach ->
+    editorView = atom.workspaceView.getActiveView()
+```
+
+We're going to use `atom.views.getView()` again to get the editor element. As in the case of the `workspaceElement`, `getView` will return a subclass of `HTMLElement` rather than an `EditorView` or jQuery object.
+
+```coffee
+# New!
+describe 'Something', ->
+  [editor, editorElement] = []
+  beforeEach ->
+    editor = atom.workspace.getActiveTextEditor()
+    editorElement = atom.views.getView(editor)
+```
+
+### Dispatching commands
+
+Since the `editorElement` objects are no longer `jQuery` objects, they no longer support `trigger()`. Additionally, Atom has a new command dispatcher, `atom.commands`, that we use rather than commandeering jQuery's `trigger` method.
+
+From this:
+
+```coffee
+# Old!
+workspaceView.trigger 'a-package:toggle'
+editorView.trigger 'find-and-replace:show'
+```
+
+To this:
+
+```coffee
+# New!
+atom.commands.dispatch workspaceElement, 'a-package:toggle'
+atom.commands.dispatch editorElement, 'find-and-replace:show'
+```
+
+## Eventing and Disposables
+
+A couple large things changed with respect to events:
+
+1. All model events are now exposed as event subscription methods that return [`Disposable`][disposable] objects
+1. The `subscribe()` method is no longer available on `space-pen` `View` objects
+1. An Emitter is now provided from `require 'atom'`
+
+### Consuming Events
+
+All events from the Atom API are now methods that return a [`Disposable`][disposable] object, on which you can call `dispose()` to unsubscribe.
+
+```coffee
+# Old!
+editor.on 'changed', ->
+```
+
+```coffee
+# New!
+disposable = editor.onDidChange ->
+
+# You can unsubscribe at some point in the future via `dispose()`
+disposable.dispose()
+```
+
+Deprecation warnings will guide you toward the correct methods.
+
+#### Using a CompositeDisposable
+
+You can group multiple disposables into a single disposable with a `CompositeDisposable`.
+
+```coffee
+{CompositeDisposable} = require 'atom'
+
+class Something
+  constructor: ->
+    editor = atom.workspace.getActiveTextEditor()
+    @disposables = new CompositeDisposable
+    @disposables.add editor.onDidChange ->
+    @disposables.add editor.onDidChangePath ->
+
+  destroy: ->
+    @disposables.dispose()
+```
+
+### Removing View::subscribe and Subscriber::subscribe calls
+
+There were a couple permutations of `subscribe()`. In these examples, a `CompositeDisposable` is used as it will commonly be useful where conversion is necessary.
+
+#### subscribe(unsubscribable)
+
+This one is very straight forward.
+
+```coffee
+# Old!
+@subscribe editor.on 'changed', ->
+```
+
+```coffee
+# New!
+disposables = new CompositeDisposable
+disposables.add editor.onDidChange ->
+```
+
+#### subscribe(modelObject, event, method)
+
+When the modelObject is an Atom model object, the change is very simple. Just use the correct event method, and add it to your CompositeDisposable.
+
+```coffee
+# Old!
+@subscribe editor, 'changed', ->
+```
+
+```coffee
+# New!
+disposables = new CompositeDisposable
+disposables.add editor.onDidChange ->
+```
+
+#### subscribe(jQueryObject, selector(optional), event, method)
+
+Things are a little more complicated when subscribing to a DOM or jQuery element. Atom no longer provides helpers for subscribing to elements. You can use jQuery or the native DOM APIs, whichever you prefer.
+
+```coffee
+# Old!
+@subscribe $(window), 'focus', ->
+```
+
+```coffee
+# New!
+{Disposable, CompositeDisposable} = require 'atom'
+disposables = new CompositeDisposable
+
+# New with jQuery
+focusCallback = ->
+$(window).on 'focus', focusCallback
+disposables.add new Disposable ->
+  $(window).off 'focus', focusCallback
+
+# New with native APIs
+focusCallback = ->
+window.addEventListener 'focus', focusCallback
+disposables.add new Disposable ->
+  window.removeEventListener 'focus', focusCallback
+```
+
+### Providing Events: Using the Emitter
+
+You no longer need to require `emissary` to get an emitter. We now provide an `Emitter` class from `require 'atom'`. We have a specific pattern for use of the `Emitter`. Rather than mixing it in, we instantiate a member variable, and create explicit subscription methods. For more information see the [`Emitter` docs][emitter].
+
+```coffee
+# New!
+{Emitter} = require 'atom'
+
+class Something
+  constructor: ->
+    @emitter = new Emitter
+
+  destroy: ->
+    @emitter.dispose()
+
+  onDidChange: (callback) ->
+    @emitter.on 'did-change', callback
+
+  methodThatFiresAChange: ->
+    @emitter.emit 'did-change', {data: 2}
+
+# Using the evented class
+something = new Something
+something.onDidChange (eventObject) ->
+  console.log eventObject.data # => 2
+something.methodThatFiresAChange()
+```
+
+## Subscribing To Commands
+
+`$.fn.command` and `View::subscribeToCommand` are no longer available. Now we use `atom.commands.add`, and collect the results in a `CompositeDisposable`. See [the docs][commands-add] for more info.
+
+```coffee
+# Old!
+atom.workspaceView.command 'core:close core:cancel', ->
+
+# When inside a View class, you might see this
+@subscribeToCommand 'core:close core:cancel', ->
+```
+
+```coffee
+# New!
+@disposables.add atom.commands.add 'atom-workspace',
+  'core:close': ->
+  'core:cancel': ->
+
+# You can register commands directly on individual DOM elements in addition to
+# using selectors. When in a View class, you should have a `@element` object
+# available. `@element` is a plain HTMLElement object
+@disposables.add atom.commands.add @element,
+  'core:close': ->
+  'core:cancel': ->
+```
+
+## Upgrading your stylesheet's selectors
+
+Many selectors have changed, and we have introduced the [Shadow DOM][shadowdom] to the editor. See [Upgrading Your Package Selectors guide][upgrading-selectors] for more information in upgrading your package stylesheets.
