Mockito and TextUtils

Question

我在android应用程序中使用mockito测试我的演示者类时遇到了一些奇怪的行为。

我有一个测试失败了，即使它通过了我的设备。行为不端的代码：

@Test
public void testValidPhoneNumber() throws Exception {
    String phone = "0123456789";
    assert(TextUtils.isDigitsOnly(phone));
}

以上操作失败，出现以下错误：

Answer 1

TextUtils不适用于mockito。

Answer 2

虽然这是一个迟来的答案，但我正在考虑分享我能想出的解决方案。以下内容适用于我的情况。我使用RobolectricTestRunner运行了测试类，这似乎解决了我的问题。

@RunWith(RobolectricTestRunner.class)
public class PhoneNumberTest {
    @Test
    public void testIsValidPhoneNumber() {
        Assert.assertEquals(true, isValidPhoneNumber("78425544587"));
    }
}

isValidPhoneNumber是一个简单的函数，如果电话号码包含所有数字，则返回true，否则返回false。

public static boolean isValidPhoneNumber(String phoneNumber) {
    if (phoneNumber == null || phoneNumber.trim().isEmpty()) return false;
    else if (!TextUtils.isDigitsOnly(phoneNumber))
        return false;
    else true;
}
