Test delle unità App Android su Eclipse + jUnit - Esecuzione test fallita: test eseguito incompleto. 1 test previsti, ricevuti 0

Question

Sto provando a ottenere alcuni test di unità per le mie app Android. Stavo seguendo il tutorial di Hello, Testing dal centro dev Android, ma mi sta dando un messaggio che recita: corsa

Test fallito: Prova di funzionamento incompleta. Attesi 1 test, ha ricevuto 0

Ecco il codice che ho:

public class LoginTest extends ActivityInstrumentationTestCase2<Login> { 

Activity mActivity; 
EditText mLoginTxt; 
EditText mPwdTxt; 
Button mLoginBtn; 
Button mClearBtn; 

public LoginTest(String pkg, Class<Login> activityClass) { 
    super("pkg_name", Login.class); 
} 

@Override 
public void setUp() throws Exception { 
    super.setUp(); 
} 

public void testPreconditions() { 

} 

public void testClear() { 
    assertTrue(true); 
} 

Ecco l'output della console:

Ed ecco l'output LogCat:

Answer 1

Ok, sembra che stavo usando il costruttore sbagliato. Ho fatto automatico eclissi generare il codice e creato questo:

public LoginTest(String pkg, Class<Login> activityClass) { 
    super(pkg, Login.class); 
} 

Tuttavia, dopo la modifica a questo:

public LoginTest() { 
    super("pkg_name", Login.class); 
} 

funziona benissimo. Non sono sicuro del perché, quindi, se qualcuno può fornire una spiegazione, sarei felice di accettarlo come risposta. Per tutti gli altri che incontrano questo errore, tutta la discussione online su questo sembra indicare che c'è qualche errore nel costruttore.

Answer 2

ho rimosso l'argomento e ora funziona, provalo.

public class LoginTest extends ActivityInstrumentationTestCase2<Login> { 

Activity mActivity; 
EditText mLoginTxt; 
EditText mPwdTxt; 
Button mLoginBtn; 
Button mClearBtn; 

public LoginTest() { 
super("pkg_name", Login.class); 
} 

@Override 
public void setUp() throws Exception { 
super.setUp(); 
} 

public void testPreconditions() { 

} 

public void testClear() { 
assertTrue(true); 
}
