MonitoringInstrumentation

public class MonitoringInstrumentation
extends ExposedInstrumentationApi

java.lang.Object
   ↳ android.app.Instrumentation
     ↳ android.support.test.internal.runner.hidden.ExposedInstrumentationApi
       ↳ android.support.test.runner.MonitoringInstrumentation
Known Direct Subclasses


An instrumentation that enables several advanced features and makes some hard guarantees about the state of the application under instrumentation.

A short list of these capabilities:

  • Forces Application.onCreate() to happen before Instrumentation.onStart() runs (ensuring your code always runs in a sane state).
  • Logs application death due to exceptions.
  • Allows tracking of activity lifecycle states.
  • Registers instrumentation arguments in an easy to access place.
  • Ensures your activities are creating themselves in reasonable amounts of time.
  • Provides facilities to dump current app threads to test outputs.
  • Ensures all activities finish before instrumentation exits.
This Instrumentation is *NOT* a test instrumentation (some of its subclasses are). It makes no assumptions about what the subclass wants to do.

finish

void finish (int resultCode, 
                Bundle results)

Ensures all activities launched in this instrumentation are finished before the instrumentation exits.

Subclasses who override this method should do their finish processing and then call super.finish to invoke this logic. Not waiting for all activities to finish() before exiting can cause device wide instability.

Parameters
resultCode int

results Bundle

interceptActivityUsing

void interceptActivityUsing (InterceptingActivityFactory interceptingActivityFactory)

Use the given InterceptingActivityFactory to create Activity instance in newActivity(ClassLoader, String, Intent). This can be used to override default behavior of activity in tests e.g. mocking startService() method in Activity under test, to avoid starting the real service and instead verifying that a particular service was started.

Parameters
interceptingActivityFactory InterceptingActivityFactory: InterceptingActivityFactory to be used for creating activity instance in newActivity(ClassLoader, String, Intent)

newActivity

Activity newActivity (Class<?> clazz, 
                Context context, 
                IBinder token, 
                Application application, 
                Intent intent, 
                ActivityInfo info, 
                CharSequence title, 
                Activity parent, 
                String id, 
                Object lastNonConfigurationInstance)

Parameters
clazz Class

context Context

token IBinder

application Application

intent Intent

info ActivityInfo

title CharSequence

parent Activity

id String

lastNonConfigurationInstance Object

Returns
Activity

Throws
InstantiationException
IllegalAccessException

newActivity

Activity newActivity (ClassLoader cl, 
                String className, 
                Intent intent)

Parameters
cl ClassLoader

className String

intent Intent

Returns
Activity

Throws
InstantiationException
IllegalAccessException
ClassNotFoundException

onCreate

void onCreate (Bundle arguments)

Sets up lifecycle monitoring, and argument registry.

Subclasses must call up to onCreate(). This onCreate method does not call start() it is the subclasses responsibility to call start if it desires.

Parameters
arguments Bundle

onDestroy

void onDestroy ()

onException

boolean onException (Object obj, 
                Throwable e)

Parameters
obj Object

e Throwable

Returns
boolean

onStart

void onStart ()

This implementation of onStart() will guarantee that the Application's onCreate method has completed when it returns.

Subclasses should call super.onStart() before executing any code that touches the application and it's state.

startActivitySync

Activity startActivitySync (Intent intent)

Parameters
intent Intent

Returns
Activity

useDefaultInterceptingActivityFactory

void useDefaultInterceptingActivityFactory ()

Use default mechanism of creating activity instance in newActivity(ClassLoader, String, Intent)

Protected methods

dumpThreadStateToOutputs

void dumpThreadStateToOutputs (String outputFileName)

Parameters
outputFileName String

getThreadState

String getThreadState ()

Returns
String

installMultidex

void installMultidex ()

installMultidexForContext

void installMultidexForContext (Context context)

Parameters
context Context

isPrimaryInstrProcess

boolean isPrimaryInstrProcess (String argsProcessName)

Checks whether this instance of instrumentation should be considered as a primary instrumentation process.

Parameters
argsProcessName String: the process name passed in via test runner args

Returns
boolean true if the given process is the primary instrumentation process

reflectivelyInvokeRemoteMethod

void reflectivelyInvokeRemoteMethod (RunnerArgs.TestArg methodName)

Helper function for various runners who extend from this class to be able to reflectively invoke the class#method that was passed in via "remoteMethod" runner argument.

Parameters
methodName RunnerArgs.TestArg: the fully qualified method to invoke (cannot be null).

setJsBridgeClassName

void setJsBridgeClassName (String className)

Parameters
className String

specifyDexMakerCacheProperty

void specifyDexMakerCacheProperty ()

waitForActivitiesToComplete

void waitForActivitiesToComplete ()

Ensures we've onStopped() all activities which were onStarted().

According to Activity's contract, the process is not killable between onStart and onStop. Breaking this contract (which finish() will if you let it) can cause bad behaviour (including a full restart of system_server).

We give the app 2 seconds to stop all its activities, then we proceed.

This should never be run on the main thread.
