public class InvocationExecution
extends Object implements IInvocationExecution

java.lang.Object
   ↳ com.android.tradefed.invoker.InvocationExecution


Class that describes all the invocation steps: build download, target_prep, run tests, clean up. Can be extended to override the default behavior of some steps. Order of the steps is driven by TestInvocation.
