junit - 安卓。机器人电动。测试 AccountManager 结果

Question

在我的应用程序中，我使用与客户经理一起获取所有者电子邮件的方法。我如何用 Robolectric 测试这种方法？我应该为此目的使用模拟吗？如果我是对的，我可以使用 Mockito 吗？有任何教程我该怎么做吗？

Answer 1

首先我实现了单元测试

// Imports are skipped
/**
 * Created by fminatchy on 25/02/14.

@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);
    }

它们是位于活动中的代码：

  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;
    }
