長い間、ここ StackOverflow のさまざまな投稿を読んで問題を解決できましたが、今では私の問題が非常に興味深いものになっています。私は立ち往生しており、誰かが私にいくつかのヒントを与えることができるかもしれません:
ActivityInstrumentationTestCase2を使用して Android アプリケーションをテストしたいと思います。私のテスト シナリオは次のようなものです。 Android デバイスの DB にいくつかのテスト データ セット (16 進文字列、有効および無効な NDEF メッセージのエンコード) があります。テストしたいアプリへの呼び出しを含む DB の行エントリごとに 1 つのテスト関数を持つ Java ファイルを生成します。
これらの関数の 1 つの例を次に示します。
public void testNdefPush0() {
Intent intent = new Intent(NfcAdapter.ACTION_TAG_DISCOVERED);
NdefMessage[] msg;
try {
msg = new NdefMessage[] { new NdefMessage(new byte[] { (byte) 0xD1,
(byte) 0x02, (byte) 0x1F, (byte) 0x53, (byte) 0x70,
(byte) 0x91, (byte) 0x01, (byte) 0x0D, (byte) 0x00,
(byte) 0x6E, (byte) 0x66, (byte) 0x63, (byte) 0x2D,
(byte) 0x66, (byte) 0x6F, (byte) 0x72, (byte) 0x75,
(byte) 0x6D, (byte) 0x2E, (byte) 0x6F, (byte) 0x72,
(byte) 0x67, (byte) 0x51, (byte) 0x01, (byte) 0x0A,
(byte) 0x55, (byte) 0x67, (byte) 0x6F, (byte) 0x6F,
(byte) 0x67, (byte) 0x6C, (byte) 0x65, (byte) 0x2E,
(byte) 0x63, (byte) 0x6F, (byte) 0x6D }) };
} catch (Exception e) {
throw new RuntimeException("Failed to create NdefMessage", e);
}
intent.putExtra(NfcAdapter.EXTRA_NDEF_MESSAGES, msg);
setActivityIntent(intent);
solo = new Solo(getInstrumentation(), getActivity());
}
ご覧のとおり、私は Robotium フレームワークを利用し、よくある質問とチュートリアルに従って、これらすべてをセットアップしました (特に: https://code.google.com/p/robotium/wiki/RobotiumForAPKFiles ) 。
I am using a specialised Instrumentation Runner, which is able to write the results in a xml file and seems suitable for my needs; here is my Manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="de.nfc"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="10" />
<uses-permission android:name="android.permission.NFC" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<instrumentation
android:name="pl.polidea.instrumentation.PolideaInstrumentationTestRunner"
android:targetPackage="se.anyro.nfc_reader" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<uses-library android:name="android.test.runner" />
</application>
</manifest>
What I have tried/achieved so far:
- The apps I would like to test are third party apps, so I re-signed them with my debug key. (works)
- Since I would like to test different apps, I implemented the generation of Java file containing the test cases on the phone; so by button click a
*.javafile holding all my tests (constructor, setUp(), testNdefPush0() ... testNdefPush100(), tearDown() ) and a suitableManifest.xmlis generated on the phone. Then these files are pulled to a PC, compiled (ant clean, ant debug, ant install -r /path/to/target.apk) in a test project and installed on the phone I can run tests using adb shell:
adb -d shell am instrument -w -r -e class de.nfc.tests.NfcTestCase -e junitOutputDirectory /mnt/sdcard/ de.nfc/pl.polidea.instrumentation.PolideaInstrumentationTestRunner
in case the test data are valid, instrumentation works and generates a xml file having the results on sdcard.
in case the test data is invalid (see example) Instrumentation crashes and does not continue with the following tests:
INSTRUMENTATION_RESULT: longMsg=java.lang.NullPointerException: Unable to start activity ComponentInfo{se.anyro.nfc_reader/se.anyro.nfc_reader.TagViewer}: java.lang.NullPointerException
Question
How can I achieve, that tests, which failed are logged as failed, and JUnit continues with the following tests.
I found here a similar question Android JUnit test suite hangs after Activity throws NullPointerException in one test case, but no replies so far :(
Has anyone experienced in testing (third) party apps by passing test data via an Intent to them and can share/provide me some advice/experience?
I do hope I made the problem clear, cause it is quite complex setup and I hope I mentioned all relevant facts for someone not familiar with the topic (you know forest and trees ;) ) If not, don't mind to ask, I'll try to explain :D
