jddf-fuzz

jddf-fuzz 生成满足 JDDF 模式的随机 JSON 文档。它适用于快速测试或生成相对真实的数据。

用法

请参阅 jddf-fuzz --help 以获取详细说明，但基本用法如下

$ echo '{ "type": "timestamp" }' | jddf-fuzz -n 5
"1950-09-01T00:06:56+00:00"
"1983-04-06T13:12:43+00:00"
"1904-12-21T19:35:20+00:00"
"1937-02-13T07:59:45+00:00"
"1971-10-19T17:26:48+00:00"

默认情况下，jddf-fuzz 从 STDIN 读取 JDDF 模式，然后产生满足该模式的无穷多个 JSON 行到 STDOUT。要使用文件而不是 STDIN，您可以将 jddf-fuzz 调用为

jddf-fuzz schema.json

演示

以下是一个使用所有 jddf 功能的模式

{
  "discriminator": {
    "tag": "type",
    "mapping": {
      "primitives": {
        "properties": {
          "any": {},
          "bool": { "type": "boolean" },
          "num": { "type": "float64" },
          "str": { "type": "string" },
          "ts": { "type": "timestamp" }
        },
        "optionalProperties": {
          "opt_bool": { "type": "boolean" }
        }
      },
      "array": {
        "properties": {
          "arr": {
            "elements": { "type": "boolean" }
          }
        }
      },
      "map": {
        "properties": {
          "map": {
            "values": { "type": "boolean" }
          }
        }
      }
    }
  }
}

以下是使用 jddf-fuzz 从该模式生成的示例值
