Revisited a number of API choices for heap growth, to simplify but also support more advanced
behavior such as keep heap dumps on test failure, or zipping heap dumps for CI upload.
HeapGrowthTraversal is now HeapDiff
ObjectGrowthDetector.forAndroidHeap().repeatingAndroidInProcessScenario() is now HeapDiff.repeatingAndroidInProcessScenario() which is now really just a wrapper for HeapDiff.repeatingDumpingTestScenario() with Android UI test specific configuration.
maxHeapDumps and scenarioLoopsPerDump have moved from being factory parameters to being per scenario parameters.
💥 #2683 Fix crash when java.lang.Object has multiple class load records in JVM heap dumps
🔨 #2682 Add support for unload class tags and records
<!-- Performing the heap growth analysis in process requires more heap. -->
<application
android:largeHeap="true"/>
</manifest>
class MyEspressoTest {
val detector = HeapDiff.repeatingAndroidInProcessScenario()
@Test
fun greeter_says_hello_does_not_grow_heap() {
// Runs repeatedly until the heap stops growing or we reach max heap dumps.
val heapDiff = detector.findRepeatedlyGrowingObjects {
onView(withId(R.id.name_field)).perform(typeText("Steve"))
onView(withId(R.id.greet_button)).perform(click())
onView(withText("Hello Steve!")).check(matches(isDisplayed()))
}
assertThat(heapDiff.growingObjects).isEmpty()
