java.lang.RuntimeException: Method isEmpty in android.text.TextUtils not mocked

Question

loginUnit.java(Test file)

@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)));
    }

UUT(unit under test) from LoginActivity

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

I always get android.text.TextUtils not mocked error, please help me?

In your src/test/java folder, add android.text package and create TextUtils.java

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