JavaBridgeArrayCoercionTest

public class JavaBridgeArrayCoercionTest extends JavaBridgeTestBase
Part of the test suite for the WebView's Java Bridge. This class tests that we correctly convert JavaScript arrays to Java arrays when passing them to the methods of injected Java objects. The conversions should follow http://jdk6.java.net/plugin2/liveconnect/#JS_JAVA_CONVERSIONS. Places in which the implementation differs from the spec are marked with LIVECONNECT_COMPLIANCE. FIXME: Consider making our implementation more compliant, if it will not break backwards-compatibility. See b/4408210. To run this test ... adb shell am instrument -w -e class com.android.webviewtests.JavaBridgeArrayCoercionTest \ com.android.webviewtests/android.test.InstrumentationTestRunner
