Android自动化测试之MonkeyRunner之MonkeyDevice（八）

Android自动化测试之MonkeyRunner之MonkeyDevice

A monkeyrunner class that represents a device or emulator accessible by the workstation runningmonkeyrunner.

This class is used to control an Android device or emulator. The methods send UI events, retrieve information, install and remove applications, and run applications.

You normally do not have to create an instance of MonkeyDevice. Instead, you useMonkeyRunner.waitForConnection() to create a new object from a connection to a device or emulator. For example, instead of using:

newdevice = MonkeyDevice()

you would use:

newdevice = MonkeyRunner.waitForConnection()

Public Methods

---

void broadcastIntent(string uri,string action,string data,string mimetype,iterable categoriesdictionary extras,component component,iterable flags)

Broadcasts an Intent to this device, as if the Intent were coming from an application. SeeIntent for more information about the arguments.

Arguments

uri action data mimetype categories extras component flags

The URI for the Intent. (see Intent.setData()).

The action for this Intent (see Intent.setAction()).

The data URI for this Intent (see Intent.setData()).

The MIME type for the Intent (see Intent.setType()).

An iterable data structure containing strings that define categories for this Intent (seeIntent.addCategory()).

A dictionary of extra data for this Intent (see Intent.putExtra() for an example).

The key for each dictionary item should be a string. The item's value can be any simple or structured data type.

The component for this Intent (see ComponentName). Using this argument will direct the Intent to a specific class within a specific Android package.

An iterable data structure containing flags that control how the Intent is handled (seeIntent.setFlags()).

void drag(tuple start,tuple end,float duration,integer steps)

Simulates a drag gesture (touch, hold, and move) on this device's screen.

Arguments

start end duration steps

The starting point of the drag gesture, in the form of a tuple (x,y) where x and y areintegers.

The end point of the drag gesture, in the form of a tuple (x,y) where x and y areintegers.

The duration of the drag gesture in seconds. The default is 1.0 seconds.

The number of steps to take when interpolating points. The default is 10.

object getProperty(string key)

Given the name of a system environment variable, returns its value for this device.

Arguments

key

The name of the system environment variable. The available variable names are listed inTable 1. Property variable names at the end of this topic.

Returns

• The value of the variable. The data format varies according to the variable requested.

object getSystemProperty(string key)

Synonym for getProperty().

Arguments

key

The name of the system environment variable. The available variable names are listed inTable 1. Property Variable Names.

Returns

• The value of the variable. The data format varies according to the variable requested.

void installPackage(string path)

Installs the Android application or test package contained in packageFile onto this device. If the application or test package is already installed, it is replaced.

Arguments

path

The fully-qualified path and filename of the .apk file to install.

dictionary instrument(string className,dictionary args)

Runs the specified component with Android instrumentation, and returns the results in a dictionary whose exact format is dictated by the component being run. The component must already be present on this device.

Use this method to start a test case that uses one of Android's test case classes. SeeTesting Fundamentals to learn more about unit testing with the Android testing framework.

Arguments

className args

The name of an Android component that is already installed on this device, in the standard form packagename/classname, where packagename is the Android package name of a.apk file on this device, and classname is the class name of an Android component (Activity, ContentProvider, Service, or BroadcastReceiver) in that file. Both packagename and classname must be fully qualified. SeeComponentName for more details.

A dictionary containing flags and their values. These are passed to the component as it is started. If the flag does not take a value, set its dictionary value to an empty string.

Returns

• A dictionary containing the component's output. The contents of the dictionary are defined by the component itself.

  If you use InstrumentationTestRunner as the class name in the componentName argument, then the result dictionary contains the single key "stream". The value of "stream" is a string containing the test output, as if InstrumentationTestRunner was run from the command line. The format of this output is described inTesting in Other IDEs.

void press(string name,integer type)
