Question

I have an Android activity that when in contact with an NFC tag calls a certain function. I would like to create tests for that.

In my test file, my logic is as follows:

// Create a ACTION_TAG_DISCOVERED
// Respond to ACTION_TAG_DISCOVERED
public void testNfc(){

}

In my code, I have a callback function “onNewIntent” which looks at the intent created when in proximity to an NFC tag:

protected void onNewIntent(Intent intent) {
    if (NfcAdapter.ACTION_TAG_DISCOVERED.equals(intent.getAction())) { ... }

But, in my test code, I cannot create an Intent of ACTION_TAG_DISCOVERED. I looked at the class here.

How do I create an ACTION_TAG_DISCOVERED intent so I can test it? Somewhere along this line:

Intent nfcIntent = new Intent(Intent.ACTION_TAG_DISCOVERED)
if(nfcIntent == ACTION_TAG_DISCOVERED)
assertSomeMethod("functionWhichHandlesNFCTagDiscovered")

Thanks much!

Answer 1

Try using this: ACTION_TAG_DISCOVERED

I haven’t tested it, but if you make an Intent like so:

Intent intent = new Intent(NfcAdapter.ACTION_TAG_DISCOVERED);
intent.putExtra(NfcAdapter.EXTRA_TAG, "");
...
intent.putByteArrayExtra(NfcAdapter.EXTRA_ID);
//etc.

you may be able to do what you’ve described.
