Javascript react native-我们应该如何处理file.snap

我正在研究如何使用jest进行测试。幸运的是，我能够使用jest测试视图

但是，我不知道

tsx.snap

文件有多有用。代码如下：

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,
        }
      }
    >

exports[`使用默认值1``正确渲染]=`
你好
世界！

对我来说，这个文件告诉我们如何将样式应用于视图的信息

如果您知道

tsx.snap

有多有用，请告诉我

提前谢谢你
