Error Mocking a @Value annotation in Spring boot

This is my class :

public class Foo {

    @Value("${myapp.foo}")
    private String foo;

    void fooValue(){
       // some code
    }
}

This is my test class :

@RunWith(MockitoJUnitRunner.class)
public class FooTest {

    @InjectMocks
    private Foo foo;

    @Before
    public void setUp() {
        ReflectionTestUtils.setField(foo, "myappfoo", "foo");
    }

    @Test
    public void testFoo() {
        // some test code
    }
}

When I am running the test I get the below error :

java.lang.IllegalArgumentException: Could not find field 'myapp.foo' of type [null] on target object [Foo@18271936] or target class [class Foo]
    at org.springframework.test.util.ReflectionTestUtils.setField(ReflectionTestUtils.java:185)
    at org.springframework.test.util.ReflectionTestUtils.setField(ReflectionTestUtils.java:120)

Also I want to use the string variable foo in my test method. How to do that.

ReflectionTestUtils receive the second parameter as the field name, you can just directly code

ReflectionTestUtils.setField(foo, "foo", "foo");

the first argument is the target, second is field name, the third is the value
