android - java.lang.RuntimeException : Method isEmpty in android. text.TextUtils 未模拟

Question

loginUnit.java(测试文件)

@RunWith(MockitoJUnitRunner.class)
public class loginUnit {
    @Mock
    TextUtils mMockTextUtils;

    @Test
    public void checkStringEmpty(){

        String empty = "";
        when(mMockTextUtils.isEmpty(empty)).thenReturn(true);
        assertThat(LoginActivity.isStringEmpty(empty),is(equalTo(true)));
    }

来自 LoginActivity 的 UUT(被测单元)

public static boolean isStringEmpty(String s){
        return TextUtils.isEmpty(s);
}

我总是得到 android.text.TextUtils not mocked 错误，请帮帮我？

Answer 1

在您的 src/test/java 文件夹中，添加 android.text 包并创建 TextUtils.java

public class TextUtils {
  public static boolean isEmpty(CharSequence str) {
    return str == null || str.length() == 0;
  }
}
