Question

我是Java的新手，我为应用程序编写了一个注销功能。我已经在测试中工作了好几个小时，但无法弄明白。这是错误：

这是我的代码：

MenuTest.java

public void testIfLogoutButtonWork() {

    getActivity();

    MainActivity myActivity = new MainActivity();
    //click the menu option

    getInstrumentation().sendKeyDownUpSync(KeyEvent.KEYCODE_MENU);
    getInstrumentation().invokeMenuActionSync(myActivity, R.id.action_logout, 0);


    //if the logout() was executed successfully, it will return true.
    assertEquals(true, TestUtils.getLogoutValue());

}

MainActivity.java

public boolean onOptionsItemSelected(MenuItem item) {

        int id = item.getItemId();
        switch (id) {
            ...............
            case R.id.action_logout:
                logout();
                break;

        }
        return super.onOptionsItemSelected(item);
    }
    logout(){
    .........
    }

我使用ActivityInstrumentationTestCase2进行测试。请帮我！提前谢谢。
