mockj

:ghost: 项目介绍

生成mock数据的利器,mockjs的java实现。同时内置随机 random 一个对象的功能

:wrench: 使用说明

配置规则:

属性名|生成规则:属性值

:one: 属性值: string
"name|min-max":"value" 通过重复 "value" 生成一个字符串,重复次数大于等于 min,小于等于 max。
"name|count": "value" 通过重复 "value" 生成一个字符串,重复次数等于 count

:two: 属性值:number
"name|+1": 100 属性值自动加 1,初始值为 100
"name|-1": 100 属性值自动减 1,初始值为 100
"name|1-100": 100 生成一个大于等于 1、小于等于 100 的整数,属性值 100 只用来确定类型
"name|1-100.1-10": 100 生成一个浮点数,整数部分大于等于 1、小于等于 100,小数部分保留 1 到 10 位

:three: 属性值:boolean
"name|1": value 生成一个固定的布尔值,值为 value
"name|@random": value 随机生成一个布尔值

:four: 属性值:object
"name|min-max": {...} 从属性值 {...} 中随机选取 min 到 max 个属性
"name|count": {...} 从属性值 {...} 中随机选取 count 个属性。

:five: 属性值:array "name|1": [{}, {} ...] 从属性值 [{}, {} ...] 中随机选取 1 个元素,作为最终值。且最终返回的数据类型与元素保持一致
"name|min-max": [{}, {} ...] 从数组 [{}, {} ...] 中挑选 x 个值生成一个新数组返回,x 的值介于 min 与 max 之间
"name|count": [{}, {} ...] 从数组 [{}, {} ...] 中挑选 count 个值生成一个新数组返回

:six: @random的支持
支持对 string、number、boolean类型的使用 @random 规则,可以随机产生 mock 数据。
"name|@random": "value"

:seven: 支持扩展函数来产生 mock 数据
value 值以 $ 开头,则会路由到 $Function.java 中,调用 $Function.java 中指定的方法。可以自由进行扩展
例如:

"flag": "$char"
"startDate": "$date"

:eight: 对随机模板的支持
手写模板通常工作量比较大,如果没有特殊要求,可以通过 TemplateHelper.java 来辅助生成随机模板

:point_down: 例子

MockTest.java

:pencil: 手写模板

String template = "{" +
                  "\"name|1-10\": \"★\"," +
                  "\"flag\": \"$char\"," +
                  "\"age|1-100\": 100," +
                  "\"next|+1\": 100," +
                  "\"point|1-100.1-2\": 100," +
                  "\"boy|@random\": true," +
                  "\"startDate\": \"$date\"," +
                  "\"endDate\": \"$date(yyyy-MM-dd)\"," +
                  "\"courses|2\": [\"语文\",\"数学\",\"英语\"]," +
                  "\"courses2|1-2\": [\"语文\",\"数学\",\"英语\"]," +
                  "\"map|2-4\": {\"110000\": \"北京市\",\"120000\": \"天津市\",\"130000\": \"河北省\",\"140000\": \"山西省\"}" +
                  "}";
Foo foo = Mock.mock(template, Foo.class);

产生的mock数据:

{
    "age":33,
    "boy":false,
    "courses":[
        "英语",
        "英语"
    ],
    "courses2":[
        "语文"
    ],
    "endDate":1537459200000,
    "flag":"s",
    "map":{
        "130000":"河北省",
        "140000":"山西省"
    },
    "name":"★★★★★★★",
    "next":100,
    "point":67.76,
    "startDate":1537524864573
}

:pencil: 使用随机模板1

Foo mock = Mock.mock(TemplateHelper.randomTemplate(Foo.class), Foo.class);

产生的随机 mock 模板:

{
    "age|0-32757":"1",
    "flag":"$char",
    "boy|@random":"true",
    "point|0-32757":"1",
    "endDate":"$date",
    "name|@random":"xx",
    "next|0-32757":"1",
    "startDate":"$date"
}

产生的 mock 数据:

{
    "next":30277,
    "flag":"g",
    "endDate":"2018-09-21T10:15:56.998Z",
    "name":"RNvK",
    "boy":"true",
    "age":18243,
    "point":30984,
    "startDate":"2018-09-21T10:15:57.007Z"
}

:pencil: 使用随机模板2

随机模板只支持对 string、number、date等数据类型进行mock,所以其他的复杂对象类型的mock,需要手动添加mock模板。mockj提供了相应的api进行操作

TemplateHelper helper = TemplateHelper.random(Foo.class);
helper.put("courses|2", new JSONArray(Lists.newArrayList("语文","数学","英语")));
helper.put("courses2|1-2", new JSONArray(Lists.newArrayList("语文","数学","英语")));
helper.put("map|2-4", JSONObject.parseObject("{\"110000\": \"北京市\",\"120000\": \"天津市\",\"130000\": \"河北省\",\"140000\": \"山西省\"}"));
helper.put("foo|1", JSONArray.parseArray("[{\"name\":\"zhangsan\",\"age\":12},{\"name\":\"lisi\",\"age\":10},{\"name\":\"wangwu\",\"age\":8}]"));
helper.put("foo1", JSONArray.parseObject("{\"name\":\"wangwu\",\"age\":8}"));
Foo mock = Mock.mock(helper.toTemplate(), Foo.class);

产生的 mock 数据:

{
    "age":6120,
    "boy":false,
    "courses":[
        "数学",
        "语文"
    ],
    "courses2":[
        "数学",
        "语文"
    ],
    "endDate":1537525215493,
    "flag":"h",
    "foo":{
        "age":8,
        "boy":false,
        "flag":"",
        "name":"wangwu",
        "next":0
    },
    "foo1":{
        "age":8,
        "boy":false,
        "flag":"",
        "name":"wangwu",
        "next":0
    },
    "map":{
        "110000":"北京市",
        "120000":"天津市",
        "130000":"河北省",
        "140000":"山西省"
    },
    "name":"rdmo",
    "next":7825,
    "point":11937,
    "startDate":1537525215494
}

:pencil: 提供反射接口,随机产生一个对象

这种方式支持的数据类型更加丰富。
例如:

Foo.class
// String 类型
private String name;
// char 类型
private char flag;
// 数字类型
private int age;
private int next;
private Double point;
// boolean 类型
private boolean boy;
// date 类型
private Date startDate;
private Date endDate;
// collection 类型
private List<String> courses;
private Set<String> courses2;
// map 类型
private Map<String, String> map;
// Object 类型
private Foo foo;
private Foo foo1;

通过Api:Foo foo = MockR.random(new TypeReference<Foo>(){}); 能产生如下的数据

{
    "age":-61382,
    "boy":true,
    "courses":[
        "hSer"
    ],
    "courses2":[
        "eatH"
    ],
    "endDate":1537524456497,
    "flag":"£",
    "foo":{
        "age":34475,
        "boy":false,
        "courses":[
            "BTvW"
        ],
        "courses2":[
            "mFWP"
        ],
        "endDate":1537524456497,
        "flag":"c",
        "map":{
            "YUJl":"IVvP"
        },
        "name":"JyAL",
        "next":-23634,
        "point":-96035,
        "startDate":1537524456497
    },
    "foo1":{
        "age":-98010,
        "boy":false,
        "courses":[
            "spTD"
        ],
        "courses2":[
            "WcQX"
        ],
        "endDate":1537524456498,
        "flag":"4",
        "map":{
            "ueYR":"ANbU"
        },
        "name":"XhFe",
        "next":75119,
        "point":21497,
        "startDate":1537524456498
    },
    "map":{
        "GzMk":"oJqQ"
    },
    "name":"tNzx",
    "next":-54482,
    "point":-20110,
    "startDate":1537524456497
}
