如何正确使用android.test.ServiceTestCase？ [英] how to correctly use android.test.ServiceTestCase?

问题描述

我的应用程序是，在/系统/应用程序

My app is a Service that runs in /system/app

com.abc.def.MyApp

试图为它编写单元测试，我在logcat中得到这个错误运行时。

Trying to write unit tests for it, I get this error in the logcat while running.

I/TestGrouping( 5647): TestCase class com.abc.def.test.MyAppTest is missing a public constructor with no parameters or a single String parameter - skipping

命令一起使用：

D:\tmp_install>adb shell am instrument -w com.abc.def.test/android.test.InstrumentationTestRunner
WARNING: linker: memtrack.jacinto6.so: unused DT entry: type 0xf arg 0x115
WARNING: linker: libsrv_um.so: unused DT entry: type 0xf arg 0xc4e

WARNING: linker: libpvr2d.so: unused DT entry: type 0xf arg 0x778

Test results for InstrumentationTestRunner=
Time: 0.0

OK (0 tests)

我的code的片段是：

My snippet of code is:

public class MyAppTest extends ServiceTestCase<MyApp> {
public MyAppTest(Class serviceClass) {
      super(serviceClass);
      Log.d(tag, "hello world! MyAppTest ctor");
}
public MyAppTest() {
  super(com.abc.def.MyApp.class);
}

...

我按照这个答案 http://stackoverflow.com/a/8981508/398348

我使用不当ServiceTestCase？

Am I using ServiceTestCase incorrectly?

推荐答案

由于Vesko所说，code是正确的;然而，问题的根源是地塞米松preOptimization - 更新到我的code组没有出现在运行时的行为。

As Vesko said, the code is correct; however root cause of the problem was Dex preOptimization - updates to my code were not showing up in the behavior of the runtime.

解决方案？我不得不推的ODEX文件以及该APK的设备。

Solution? I had to push the odex file as well as the apk to the device.
