stub
public static final @NonNull Stub<Object, @NonNull R> <R extends Object> stub(
@NonNull Iterable<@NonNull R> queue,
@NonNull Function0<R> defaultHandler
)
Creates a stub that returns elements from a queue or produces it using the default handler.
Example Stub where the output is fixed:
import androidx.health.connect.client.testing.stubs.Stub import androidx.health.connect.client.testing.stubs.stub val stub: Stub<Int, String> = stub("Fixed response") stub.next(request = 0) // Returns "Fixed response" stub.next(request = 1) // Returns "Fixed response"
Example Stub with 2 elements in a queue that once consumed returns a fixed response :
import androidx.health.connect.client.testing.stubs.Stub import androidx.health.connect.client.testing.stubs.stub val stub: Stub<Int, String> = stub(listOf("zero", "one")) { "Default" } stub.next(request = 0) // Returns "zero" stub.next(request = 0) // Returns "one" stub.next(request = 0) // Returns "Default"
Example Stub that throws an exception when used:
import androidx.health.connect.client.testing.stubs.Stub import androidx.health.connect.client.testing.stubs.stub val stubWithException: Stub<Int, String> = stub { throw Exception() } stubWithException.next(request = 0) // Throws exception stubWithException.next(request = 0) // Throws exception
Example Stub with 1 element in a queue that once consumed throws an exception when used:
import androidx.health.connect.client.testing.stubs.Stub import androidx.health.connect.client.testing.stubs.stub val stubWithQueueAndException: Stub<Int, String> = stub(queue = listOf("first")) { throw Exception() } stubWithQueueAndException.next(request = 0) // Returns "first" stubWithQueueAndException.next(request = 0) // Throws exception
