android - 如何在 Android 中测试 AlertDialog？

Question

我正在尝试使用 ActivityInstrumentationTestCase2 测试 AlertDialog。

原代码如下:

    this.setmBtAppelerFixe(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            AlertDialog.Builder dialog = new AlertDialog.Builder(InterventionImmobiliereDetailsActivity.this);
            dialog.setTitle("Appel");
            dialog.setMessage("Appeler le contact ?");
            dialog.setCancelable(true);
            dialog.setNegativeButton("Non", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    dialog.dismiss();
                }
            });
            dialog.setPositiveButton("Oui", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    InterventionImmobiliereDetailsActivity.this.lancerIntentAppel(mIntervention.getTelContact());
                }
            });

            mAdAppelerFixe = dialog.create();
            mAdAppelerFixe.show();
        }
    });

现在我无法点击肯定按钮。此代码似乎不起作用:

    mActivity.runOnUiThread(new Runnable() {
        @Override
        public void run() {
            assertTrue(mLLAppelerFixe.performClick());

            AlertDialog mDialog = mActivity.getAdAppelerFixe();
            assertTrue(mDialog.isShowing());

            Button okButton = mDialog.getButton(AlertDialog.BUTTON_POSITIVE);

            assertTrue(okButton.performClick());
            assertTrue(mActivity.isNumeroValide());
        }
    });

首先，我在布局上单击以打开 AlertDialog。然后我得到 OK_BUTTON 并点击它。它应该将 numeroValide bool 值设置为 true。但是什么都没有。

我怎样才能简单地测试带有按钮的 AlertDialog？

这在我的 nexus 4 设备上运行完美:

@MediumTest
public void testStartMyActivity() {
    monitor = getInstrumentation().addMonitor(MyActivity.class.getName(), null, false);

    TouchUtils.clickView(this, startMyActivityButton);

    MyActivity myActivity = (MyActivity) monitor.waitForActivityWithTimeout(2000);
    assertNotNull("MyActivity activity not started, activity is null", myActivity);

    AlertDialog dialog = myActivity.getLastDialog(); // I create getLastDialog method in MyActivity class. Its return last created AlertDialog
    if (dialog.isShowing()) {
        try {
            performClick(dialog.getButton(DialogInterface.BUTTON_POSITIVE));
        } catch (Throwable e) {
            e.printStackTrace();
        }
    }

    myActivity.finish();
    getInstrumentation().removeMonitor(monitor);
}

private void performClick(final Button button) throws Throwable {
    runTestOnUiThread(new Runnable() {
        @Override
        public void run() {
            button.performClick();
        }
    });
    getInstrumentation().waitForIdleSync();
}
