Question

I have a app which will download a file from web. The download action is triggered by clicking a button and then it will start a new thread to download this file.

What I want to do now is to test if the download is succesfull or not.
So I wrote the following test code :

private void testGenerateFile() throws Exception {
    try {
        runTestOnUiThread(new Runnable() {
            @Override
            public void run() {
                ((EditText)mActivity.findViewById(R.id.edit_server)).setText("http://192.168.120.248/phonebook.xml");
                click(R.id.ok);
            }
        });
    } catch (Throwable e) {
    }
}

But after executing it, the file hasn’t been downloaded. But if I add Thread.sleep(2000) at the end, the file is generated. But I think this is not a proper solution. Can you help me? Thanks.

If you know the location where the file is downloaded to, and the size of the file, you could periodically check (till a predefined duration) for the file being created and downloaded. You could assume that the file is successfully downloaded if the file size meets the original size.
