react-native - What should we do with file.snap

I am researching about testing using jest. Luckily, I am able to use jest for testing view.

However, I don't know how useful is the tsx.snap file. Below is the code:

exports[`renders correctly with defaults 1`] = `
<View
  style={
    Object {
      "alignItems": "center",
      "alignSelf": "center",
    }
  }
>
  <Text
    style={
      Object {
        "color": "#999",
        "fontWeight": "bold",
      }
    }
  >
    Hello

    World!
  </Text>
  <View
    style={
      Object {
        "alignItems": "stretch",
        "alignSelf": "center",
        "borderWidth": 5,
        "flexDirection": "row",
        "minHeight": 70,
      }
    }
  >
    <View
      style={
        Object {
          "flex": 1,
          "paddingVertical": 0,
        }
      }
    >
      <View
        accessibilityLabel="decrement"
        accessibilityRole="button"
        accessibilityStates={Array []}
        accessible={true}
        focusable={true}
        isTVSelectable={true}
        onClick={[Function]}
        onResponderGrant={[Function]}
        onResponderMove={[Function]}
        onResponderRelease={[Function]}
        onResponderTerminate={[Function]}
        onResponderTerminationRequest={[Function]}
        onStartShouldSetResponder={[Function]}
        style={
          Object {
            "opacity": 1,
          }
        }
      >
        <View
          style={
            Array [
              Object {},
            ]
          }
        >
          <Text
            style={
              Array [
                Object {
                  "color": "#007AFF",
                  "fontSize": 18,
                  "padding": 8,
                  "textAlign": "center",
                },
                Object {
                  "color": "red",
                },
              ]
            }
          >
            -
          </Text>
        </View>
      </View>
    </View>
    <View
      style={
        Object {
          "flex": 1,
          "paddingVertical": 0,
        }
      }
    >
      <View
        accessibilityLabel="increment"
        accessibilityRole="button"
        accessibilityStates={Array []}
        accessible={true}
        focusable={true}
        isTVSelectable={true}
        onClick={[Function]}
        onResponderGrant={[Function]}
        onResponderMove={[Function]}
        onResponderRelease={[Function]}
        onResponderTerminate={[Function]}
        onResponderTerminationRequest={[Function]}
        onStartShouldSetResponder={[Function]}
        style={
          Object {
            "opacity": 1,
          }
        }
      >
        <View
          style={
            Array [
              Object {},
            ]
          }
        >
          <Text
            style={
              Array [
                Object {
                  "color": "#007AFF",
                  "fontSize": 18,
                  "padding": 8,
                  "textAlign": "center",
                },
                Object {
                  "color": "blue",
                },
              ]
            }
          >
            +
          </Text>
        </View>
      </View>
    </View>
  </View>
</View>
`;

For me, this file is telling us the information of how styles are applied to our view.

If you know how useful the tsx.snap is, please let me know.

Thank you in advance!
