Public functions

getArguments

fun getArguments(): Bundle

Returns a copy of instrumentation arguments Bundle. Use this to get a Bundle containing the command line arguments passed to Instrumentation into your test.

This Bundle is not guaranteed to be present under all instrumentations.

Returns
`Bundle`	Bundle the arguments for this instrumentation.

Throws
`java.lang.IllegalStateException`	if no argument Bundle has been registered.

getContext

fun getContext(): Context

Return the Context of this instrumentation's package. Use this to get a Context representing Instrumentation#getContext() into your test.

getInstrumentation

fun getInstrumentation(): Instrumentation

Returns the instrumentation currently running. Use this to get an Instrumentation into your test.

Throws
`java.lang.IllegalStateException`	if instrumentation hasn't been registered

getTargetContext

fun getTargetContext(): Context

Return a Context for the target application being instrumented. Use this to get a Context representing Instrumentation#getTargetContext() into your test.

registerInstance

fun registerInstance(instrumentation: Instrumentation, arguments: Bundle): Unit

Records/exposes the instrumentation currently running and stores a copy of the instrumentation arguments Bundle in the registry.

This is a global registry - so be aware of the impact of calling this method!

Parameters
`instrumentation: Instrumentation`	the instrumentation currently running.
`arguments: Bundle`	the arguments for this application. Null deregisters any existing arguments.
