wda-driver

中文版

Facebook WebDriverAgent Node Client Library (not official)

Most functions finished.

Installation

1. You need to start WebDriverAgent by yourself

Follow the instructions in https://github.com/facebook/WebDriverAgent

It is better to start with Xcode to prevent CodeSign issues.

But it is also ok to start WDA with command line.

xcodebuild -project WebDriverAgent.xcodeproj -scheme WebDriverAgentRunner -destination 'platform=iOS Simulator,name=iPhone 6' test

2. Install wda-driver client

npm install --save wda-driver

TCP connection over USB (optional)

You can use wifi network, it is very convinient, but not very stable enough.

I found a tools named iproxy which can forward device port to localhost, it's source code is here https://github.com/libimobiledevice/libusbmuxd

The usage is very simple iproxy <local port> <remote port> [udid]

Configuration

const wda = require('wda-driver')

How to use

Create a client

const wda = require('wda-driver')

const c = new wda.Client('http://localhost:8100')

// http://localhost:8100 is the default value
c = wda.Client()

Client

// Show status
console.log(await c.status())

// Press home button
await c.home()

// Hit healthcheck
await c.healthcheck()

// Get page source

// format (str): only 'xml' and 'json' source types are supported
// accessible (bool): when set to true, format is always 'json'
const source = await c.source() // format XML
const source = await c.source(null, true) // default false, format JSON

Take screenshot, only can save format png, if params is empty, it will return base64 buffer

await c.screenshot('screen.png')

Get information about the current app

await c.getActiveAppInfo();

do actions chain

/**
 Perform complex touch action in scope of the current application.
 Touch actions are represented as lists of dictionaries with predefined sets of values and keys.
 Each dictionary must contain 'action' key, which is one of the following:
 - 'tap' to perform a single tap
 - 'longPress' to perform long tap
 - 'press' to perform press
 - 'release' to release the finger
 - 'moveTo' to move the virtual finger
 - 'wait' to modify the duration of the preceeding action
 - 'cancel' to cancel the preceeding action in the chain
 Each dictionary can also contain 'options' key with additional parameters dictionary related to the appropriate action.
 
 The following options are mandatory for 'tap', 'longPress', 'press' and 'moveTo' actions:
 - 'x' the X coordinate of the action
 - 'y' the Y coordinate of the action
 - 'element' the corresponding element instance, for which the action is going to be performed
 If only 'element' is set then hit point coordinates of this element will be used.
 If only 'x' and 'y' are set then these will be considered as absolute coordinates.
 If both 'element' and 'x'/'y' are set then these will act as relative element coordinates.
 
 It is also mandatory, that 'release' and 'wait' actions are preceeded with at least one chain item, which contains absolute coordinates, like 'tap', 'press' or 'longPress'. Empty chains are not allowed.
 
 The following additional options are available for different actions:
 - 'tap': 'count' (defines count of taps to be performed in a row; 1 by default)
 - 'longPress': 'duration' (number of milliseconds to hold/move the virtual finger; 500.0 ms by default)
 - 'wait': 'ms' (number of milliseconds to wait for the preceeding action; 0.0 ms by default)
 
 List of lists can be passed there is order to perform multi-finger touch action. Each single actions chain is going to be executed by a separate virtual finger in such case.

const actions = [
  {
    action: 'tap',
    options: {
      x: 300,
      y: 100
    }
  },
  {
    action: 'wait',
    options: {
      ms: 700
    }
  },
  {
    action: 'tap',
    options: {
      x: 300,
      y: 100
    }
  }
];
await session.chainOperation(actions);

Determine if the device is locked

await c.isLocked();

Open app

const s = await c.session('com.apple.Health')
console.log(await s.orientation())
await s.close()

For web browser like Safari you can define page whit which will be opened:

const s = await c.session('com.apple.mobilesafari', ['-u', 'https://www.google.com/ncr'])
console.log(await s.orientation())
await s.close()

Session operations

// Current bundleId and sessionId
console.log(s.getId(), s.getBundleId())

// One of <PORTRAIT | LANDSCAPE>
console.log(await s.orientation()) // expect PORTRAIT

// Change orientation
// LANDSCAPE | PORTRAIT | UIA_DEVICE_ORIENTATION_LANDSCAPERIGHT |UIA_DEVICE_ORIENTATION_PORTRAIT_UPSIDEDOWN
await s.orientation(orientation)

// Deactivate App for some time
await s.deactivate(5) // 5s

// Get width and height
console.log(await s.getWindowSize())
// Expect json output
// For example: {'height': 736, 'width': 414}

// Simulate touch
await s.tap(88, 200)

// Double touch
await s.doubleTap(200, 200)

// Simulate swipe, utilizing drag api
await s.swipe(x1, y1, x2, y2, 0.5) // 0.5s
await s.swipeLeft()
await s.swipeRight()
await s.swipeUp()
await s.swipeDown()

// tap hold
await s.tapHold(x, y, 1.0)

Find element

// For example, expect: true or false
// using id to find element and check if exists
const selector = s.selector({id: "URL"})
await selector.exists() // return true or false

// using id or other query conditions
s.selector({id: 'URL'})
s.selector({name: 'URL'})
s.selector({text: "URL"}) // text is alias of name
s.selector({nameContains: 'UR'})
s.selector({label: 'Address'})
s.selector({labelContains: 'Addr'})
s.selector({name:'URL', index: 1}) # find the second element. index starts from 0

// combines search conditions
// attributes bellow can combines
// :"className", "name", "label", "visible", "enabled"

s.selector({className: 'Button', name: 'URL', visible: true, labelContains: "Addr"})

More powerful findding method

s.selector({xpath: '//Button[@name="URL"]'})
s.selector({classChain: '**/Button[`name == "URL"`]'})
s.selector({predicate: 'name LIKE "UR*"'})

Element operations (eg: tap, scroll, set_text etc...)

Exmaple search element and tap

// Get first match Element object
// The function get() is very important.it will return an Element object
// when elements founded in 10 seconds(:default:), Element object returns

const e = await s.selector({text: 'Dashboard'}).get(10) // e is elements object
await e.tap() // tap element

Click element if exists

await s.selector({text: 'Dashboard'}).clickExists() // return immediately if not found

await s.selector({text: 'Dashboard'}).clickExists(5) // wait for 5s

Other Element operations

// Check if elements exists
console.log(await s.selector({text: 'Dashboard'}).exists())

// Find all matches elements, return Array of Element object
await s.selector({className: 'Other'}).findElements()

// Use index to find second element
await s.selector({className: 'Other', index: 2}).exists()

// Use child to search sub elements
await s.selector({text: 'Dashboard'}).child({className: 'Cell'}).exists()

// Default timeout is 10 seconds
// But you can change by
s.setTimeout(50)

// do element operations
await e.tap()
await e.click() // alias of tap
// The default keyboard must be requested
await e.clearText()
await e.setText("Hello world")
await e.tapHold(2) // tapAndHold for 2.0s

await e.scroll() // scroll to make element visiable

// directions can be "up", "down", "left", "right"
// swipe distance default to its height or width according to the direction
await e.scroll('up', 100)

// Set text
await e.setText("Hello WDA") // normal usage
await e.setText("Hello WDA\n") // send text with enter
await e.setText("\b\b\b") // delete 3 chars

// Wait element gone
await s({className: 'Other'}).waitGone(10)

// Swipe TODO
// s(className="Image").swipe("left")

// Pinch
s(className="Map").pinch(2, 1) // scale=2, speed=1
s(className="Map").pinch(0.1, -1) // scale=0.1, speed=-1 (I donot very understand too)

// properties (bool)
await e.getAccessible()
await e.getDisplayed()
await e.getEnabled()
await e.getVisible()
await e.getAccessibilityContainer()

// properties (str)
await e.getId() 
await e.getLabel()
await e.getClassName()
await e.getText()
await e.getName()
await e.getDisplayed()
await e.getEnabled()
await e.getValue()
await e.getValue()

// Bounds return namedtuple
const rect = await e.getBounds() // Rect { x: 0, y: 73, width: 375, height: 666 }
rect.y // 73

Alert

console.log(await s.alert().exists())
console.log(await s.alert().text())
console.log(await s.alert().text())

await s.alert().accept() // Actually do click first alert button
await s.alert().dismiss() // Actually do click second alert button
await s.alert().wait(5) // if alert apper in 5 second it will return true,else return false (default 20.0)
await s.alert().wait() // wait alert apper in 20 second

await s.alert().buttons()
// example return: ["设置", "好"]

await s.alert().click('好')
