junit之安卓。机器人电子。测试 AccountManager 结果

在我的应用程序中，我使用客户经理的方法来获取所有者电子邮件。如何使用 Robolectric 测试此方法？我应该为此目的使用 mock 吗？如果我是对的，我可以使用 Mockito 吗？有什么教程我可以做到吗？

请您参考如下方法:

首先我实现了单元测试

@RunWith(RobolectricTestRunner.class) 
@Config(manifest = "/src/main/AndroidManifest.xml") 
public class TestAuthorization { 
 
    AccountManager accountManager; 
 
    Account account0; 
    Account account1; 
    Account account2; 
 
    @Before 
    public void init() { 
        creationComptes(); 
        accountManager = AccountManager.get(Robolectric.application); 
        shadowOf(accountManager).addAccount(account0); 
        shadowOf(accountManager).addAccount(account1); 
        shadowOf(accountManager).addAccount(account2); 
    } 
 
    @Test 
    public void test_comptes() { 
       final AlbumsActivity activity = Robolectric.buildActivity(AlbumsActivity.class).create().get(); 
 
       final String[] accountsName = activity.getGoogleAccounts(); 
       assertThat(Arrays.asList(accountsName)).containsExactly("compte n°1", "compte n°3"); 
 
 
    } 
 
    private void creationComptes() { 
        account0 = new Account("compte n°1", GoogleAccountManager.ACCOUNT_TYPE); 
        account1 = new Account("compte n°2", "pas google"); 
        account2 = new Account("compte n°3", GoogleAccountManager.ACCOUNT_TYPE); 
    } 

  public String[] getGoogleAccounts() { 
        final AccountManager accountManager = AccountManager.get(this.getApplicationContext()); 
        Account[] accounts = accountManager.getAccountsByType(GoogleAccountManager.ACCOUNT_TYPE); 
        String[] names = new String[accounts.length]; 
        for (int i = 0; i < names.length; i++) { 
            names[i] = accounts[i].name; 
        } 
        return names; 
    }
