I have a class ClassToTest which has a dependency on ClassToMock. 

```java
public class ClassToMock {

  private static final String MEMBER_1 = FileReader.readMemeber1();

  protected void someMethod() {
    ...
  }
}

```

The unit test case for ClassToTest. 

```java
public class ClassToTestTest {
  private ClassToMock _mock;

  @Before
  public void setUp() throws Exception {
     _mock = mock(ClassToMock.class)
  }

}

```

When mock is called in the setUp() method, FileReader.readMemeber1(); is executed. Is there a way to avoid this? I think one way is to initialize the MEMBER\_1 inside a method. Any other alternatives? 

Thanks!
