Find Text tag with content in Enzyme

I have the following React Native code in a component called MyComponent:

<Text> {Constants.MY_TEXT} </Text>

I am trying to test it like this with enzyme:

const wrapper = shallow(
            <MyComponent/>
        );
expect(wrapper.find(<Text> {Constants.MY_TEXT} </Text>)).toHaveLength(1);

However, the test fails because 0 occurrences of <Text> {Constants.MY_TEXT} </Text> are found.

I think this is because wrapper.find does not understand the argument I am passing to it.

I also tried searching just for the text, without the tag:

expect(wrapper.find({Constants.MY_TEXT})).toHaveLength(1);

However, this fails with:

Unexpected token, expected ,

Any idea how to make the test see the Text tag?
