android-studio - 在AndroidTest中报错

Question

1.我定义了一个测试解析JSON数据的类，方法里调用了GSON框架的代码，但是在运行方法的时候出现了报错：Test running failed: Unable to find instrumentation info for: ComponentInfo{com.example.lweicheng.splash.test/android.test.InstrumentationTestRunner}
如下为相关代码：

public class GsonTest extends AndroidTestCase {


    public void testJson() {
        String json = "{\"name\":\"小王\",\"age\":18,\"gander\":\"true\"}";
        Gson gson = new Gson();
        Person person=gson.fromJson(json,Person.class);
        Log.d("lweicheng",person.toString());
    }

    class Person {
        private String name;
        private int age;
        private boolean gender;

        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }

        public int getAge() {
            return age;
        }

        public void setAge(int age) {
            this.age = age;
        }

        public boolean isGender() {
            return gender;
        }

        public void setGender(boolean gender) {
            this.gender = gender;
        }

        public String toString() {
            return "name" + name + ",age:" + age + ",gender:" + gender;
        }
    }
}
如下是Androidmanifest文件的配置
  <activity android:name=".RegisterActivity"></activity>
    <uses-library android:name="android.test.runner"/>

</application>
<instrumentation android:name="android.test.InstrumentationTestRunner"
    android:targetPackage="com.example.lweicheng.splash.GsonTest"/>
    
    请问各位大神是否遇过同样的问题？ 我的上述代码出了什么问题？ 谢谢！

给你个参考:

就你的代码来看,你的targetpackage为:com.example.lweicheng.splash.GsonTest,这是你要测试的类名.
