When a I{multi-device} test is running the available devices are available in a list named L{self.devices} which has the corresponding L{ConnectedDevices} entries.

Also, in the case of I{multi-devices} tests and to be backward compatible with I{single-device} tests the default device, the first one in the devices list, is assigned to L{self.device}, L{self.vc} and L{self.serialno} too.

B{verbose}: The verbosity of the tests. This can be changed from the test command line using the command line option C{-v} or C{–verbose}.

defaultDevice = None

adb

The adb command

assertServiceResponse(response)

Checks whether the response received from the server is correct or raises and Exception.

@type response: str @param response: Response received from the server

@raise Exception: If the response received from the server is invalid

build

The map containing the device’s build properties: version.sdk, version.release

click(x=-1, y=-1, selector=None)

An alias for touch.

Parameters:

• x – x coordinate

• y – y coordinate

• selector – the selector, could be None

Returns:

the result of the operation

static connectToDeviceOrExit(timeout=60, verbose=False, ignoresecuredevice=False, ignoreversioncheck=False, serialno=None, adbhostname='localhost', adbport=5037, connect=<function connect>)

Connects to a device which serial number is obtained from the script arguments if available or using the default regex .* if not provided.

If the connection is not successful the script exits.

Parameters:

• timeout (int) – timeout for the connection

• verbose (bool) – Verbose output

• ignoresecuredevice (bool) – ignores a secure device

• ignoreversioncheck (bool) – ignores the version check

• serialno (str) – the serial number of the device (can be None)

• adbhostname (str) – The adb hostname

• adbport (int) – The adb port

• connect (function) – Connect method to use to connect to ADB

Returns:

the device and serialno used for the connection

Return type:

Tuple[AdbClient, str]

History

In MonkeyRunner times, this method was a way of overcoming one of its limitations. MonkeyRunner.waitForConnection() returns a MonkeyDevice even if the connection failed. Then, to detect this situation, device.wake() is attempted and if it fails then it is assumed the previous connection failed.

device

The C{AdbClient} device instance

display

The map containing the device’s display properties: width, height and density

static distance(tree1, tree2)

dump(window=-1, sleep=1)

Dumps the window content.

Sleep is useful to wait some time before obtaining the new content when something in the window has changed.

@type window: int or str @param window: the window id or name of the window to dump. The B{name} is the package name or the window name (i.e. StatusBar) for system windows. The window id can be provided as C{int} or C{str}. The C{str} should represent and C{int} in either base 10 or 16. Use -1 to dump all windows. This parameter only is used when the backend is B{ViewServer} and it’s ignored for B{UiAutomator}. @type sleep: int @param sleep: sleep in seconds before proceeding to dump the content

@return: the list of Views as C{str} received from the server after being split into lines

hammingDistance(tree)

ignoreUiAutomatorKilled

On some devices (i.e. Nexus 7 running 4.2.2) uiautomator is killed just after generating the dump file. In many cases the file is already complete so we can ask to ignore the ‘Killed’ message by setting L{ignoreuiautomatorkilled} to C{True}.

Changes in v2.3.21 that uses C{/dev/tty} instead of a file may have turned this variable unnecessary, however it has been kept for backward compatibility.

imageDirectory = None

isKeyboardShown()
