Queries

This is list of most common endpoints with some query examples using curl with pre-set environment variables:

  • DEVICE_URL set as device URL (eg. http://localhost:8100)
  • SESSION_ID set as session id. Returned by start session command e.g. D15E12F6-CA23-4CD4-89F9-E5C5EA6F4FAD. If you want to use WebDriverAgent without launching an app you can use the default session ID reported by the /status endpoint.
  • JSON_HEADER='-H "Content-Type: application/json"'

WebDriverAgent is intended to implement WebDriver spec so we will not get much into details as you can simply read WebDriver spec.

Checking service status

curl -X GET $JSON_HEADER $DEVICE_URL/status

Session handling

Starting session and launching application

If application is already installed on device you can start it using bundleId parameter:

curl -X POST $JSON_HEADER \
-d "{\"desiredCapabilities\":{\"bundleId\":\"com.apple.mobilesafari\"}}" \
$DEVICE_URL/session

It is also possible to request to install application before launching it by adding app parameter:

curl -X POST $JSON_HEADER \
-d "{\"desiredCapabilities\":{\"bundleId\":\"com.apple.mobilesafari\", \"app\":\"[host_path]/magicapp.app\"}}" \
$DEVICE_URL/session

If you want to use WebDriverAgent without launching an app you can use the default session ID reported by the /status endpoint.

Querying current session

curl -X GET $JSON_HEADER $DEVICE_URL/session/$SESSION_ID

Removing session and killing application

curl -X DELETE $JSON_HEADER $DEVICE_URL/session/$SESSION_ID

Application related queries

Inspector

Open web browser at inspector endpoint /inspector

Go to home screen

curl -X POST $JSON_HEADER -d "" $DEVICE_URL/wda/homescreen

Get a screenshot

curl -X GET $JSON_HEADER $DEVICE_URL/screenshot

Deactivate application for given time

curl -X POST $JSON_HEADER -d "{\"duration\":3}" $DEVICE_URL/session/$SESSION_ID/wda/deactivateApp

Change device orientation

Supported orientations are:

  • PORTRAIT
  • LANDSCAPE
  • UIA_DEVICE_ORIENTATION_LANDSCAPERIGHT
  • UIA_DEVICE_ORIENTATION_PORTRAIT_UPSIDEDOWN
curl -X POST $JSON_HEADER \
-d "{\"orientation\":\"LANDSCAPE\"}" \
$DEVICE_URL/session/$SESSION_ID/orientation`

Source aka tree

curl -X GET $JSON_HEADER $DEVICE_URL/source

Searching for elements

Some of element search endpoints use property names listed here.

You can search for elements by:

  • property with given value (link text)
curl -X POST $JSON_HEADER \
-d "{\"using\":\"link text\",\"value\":\"label=Apple\"}" \
$DEVICE_URL/session/$SESSION_ID/elements
  • property with given partial value (partial link text)
curl -X POST $JSON_HEADER \
-d "{\"using\":\"partial link text\",\"value\":\"label=App\"}" \
$DEVICE_URL/session/$SESSION_ID/elements
  • using class name 
curl -X POST $JSON_HEADER \
-d "{\"using\":\"class name\",\"value\":\"XCUIElementTypeButton\"}" \
$DEVICE_URL/session/$SESSION_ID/elements
  • using xpath 
curl -X POST $JSON_HEADER \
-d "{\"using\":\"xpath\",\"value\":\"//XCUIElementTypeButton[@name='Share']\"}" \
$DEVICE_URL/session/$SESSION_ID/elements

It is not recommended to use xpath queries, since they are not supported by XCTest natively and therefore are slow. Replace them with faster query types if possible.

  • using predicate string 
curl -X POST $JSON_HEADER \
-d "{\"using\":\"predicate string\",\"value\":\"wdVisible==1\"}" \
$DEVICE_URL/session/$SESSION_ID/elements

Follow Predicate Queries Construction Rules to compile predicate queries properly and to avoid unexpected errors.

  • using class chain 
curl -X POST $JSON_HEADER \
-d "{\"using\":\"class chain\",\"value\":\"**/XCUIElementTypeOther[`value BEGINSWITH 'blabla'`]/**/XCUIElementTypeButton[`name BEGINSWITH 'cool'`][-1]\"}" \
$DEVICE_URL/session/$SESSION_ID/elements

Follow Class Chain Queries Construction Rules to compile class chain queries properly and to avoid unexpected errors.

In same manner you can query subelements of given element with id by using /element/:id/elements endpoint.

Interacting with elements

Querying properties

All elements returned by search endpoints have assigned element_id. Given element_id you can query properties like enabled, rect, size, location, text, displayed, accessible, name e.g.:

curl -X GET $JSON_HEADER $DEVICE_URL/session/$SESSION_ID/element/5/displayed

or using by using element/5/attribute/:name endpoint e.g.:

curl -X GET $JSON_HEADER $DEVICE_URL/session/$SESSION_ID/element/5/attribute/name

Tapping element

curl -X POST $JSON_HEADER -d "" $DEVICE_URL/session/$SESSION_ID/element/5/click

Typing text

curl -X POST $JSON_HEADER \
-d "{\"value\":[\"h\",\"t\",\"t\",\"p\",\":\",\"/\",\"/\",\"g\",\"i\",\"t\",\"h\",\"u\",\"b\",\".\",\"c\",\"o\",\"m\",\"\\n\"]}" \
$DEVICE_URL/session/$SESSION_ID/element/5/value

Clearing text

curl -X POST $JSON_HEADER -d "" $DEVICE_URL/session/$SESSION_ID/element/5/clear

Alerts

Get alert

curl -X GET $JSON_HEADER $DEVICE_URL/session/$SESSION_ID/alert/text

Accept alert

curl -X POST $JSON_HEADER -d "" $DEVICE_URL/session/$SESSION_ID/alert/accept

Dismiss alert

curl -X POST $JSON_HEADER -d "" $DEVICE_URL/session/$SESSION_ID/alert/dismiss

Touch ID

Match TouchID

curl -X POST $JSON_HEADER -d "{\"match\":1}" $DEVICE_URL/session/$SESSION_ID/wda/touch_id

Do not match TouchID

curl -X POST $JSON_HEADER -d "{\"match\":0}" $DEVICE_URL/session/$SESSION_ID/wda/touch_id
