我在 Eclipse 中运行 Android JUnit 测试。我有一个在 JUnit 运行期间测试的函数。在函数内部，我将一些值保存到本地文件中。但它似乎没有被保存。是什么原因，以及如何从该功能在控制台中输出一些数据？

它与 robots 开发人员提供的示例应用程序中的单元测试代码基本相同。

public void testDisplayBlackBox() {
        //Enter any integer/decimal value for first editfield, we are writing 10
        solo.enterText(0, "10");
        //Enter any interger/decimal value for first editfield, we are writing 20
        solo.enterText(1, "20");
        //Click on Multiply button
        solo.clickOnButton("Multiply");
        //Verify that resultant of 10 x 20
        assertTrue(solo.searchText("200"));
        ArrayList <View> aview= solo.getCurrentViews();
        for (View v:aview)
        {
            //System.out.println(v.toString());
            //solo.enterText(0, v.toString());
            try {
                FileUtils.writeStringToFile(new File("test.txt"), v.toString());
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            //FileUtils 
        }
        //aview.get(0).
    }

在测试执行期间，您无法在本地保存文件。您可以将其保存在例如 sd-card 上，然后您可以通过 adb 提取它（更多帮助：http: //developer.android.com/tools/help/adb.html）：

public void testDisplayBlackBox() {
    //Enter any integer/decimal value for first editfield, we are writing 10
    solo.enterText(0, "10");
    //Enter any interger/decimal value for first editfield, we are writing 20
    solo.enterText(1, "20");
    //Click on Multiply button
    solo.clickOnButton("Multiply");
    //Verify that resultant of 10 x 20
    assertTrue(solo.searchText("200"));
    ArrayList <View> aview= solo.getCurrentViews();
    StringBuilder sB = new StringBuilder();
    for (View v:aview)
    {           
        sB.append(v.toString());
    }
    saveToFile(sB.toString())
}


public void saveToFile(String text) {
    try {
        String path = Environment.getExternalStorageDirectory();
        File file = new File(path, test.txt);
        FileOutputStream fos = new FileOutputStream(file);
        byte[] data = text.getBytes();
        fos.write(data);
        fos.flush();
        fos.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

对于调试，您可以使用 android.util.Log：

Log.d("TEST", "text");
