#### 斷言測試實例
* * * * *
1.設置環境變量
~~~
postman.setEnvironmentVariable("key", "value");
~~~
例子： `postman.setEnvironmentVariable("url", "http://192.168.36.47/v2/api"); `
使用環境變量的格式：`{{url}}`
1.1清除環境變量
~~~
postman.clearEnvironmentVariable("variable_key");
~~~
例子：`postman.clearEnvironmentVariable("url");`
2.設置一個全局變量
~~~
postman.setGlobalVariable("key", "value");
~~~
例子：`postman.setGlobalVariable("username", "123@qq.com");`
使用全局變量格式：`{{variableName}}`
2.1清除一個全局變量
~~~
postman.clearGlobalVariable("key", "value");
~~~
例子：`postman.clearGlobalVariable("username", "123@qq.com"); `
3.檢查響應體包含一個字符串
~~~
tests["Body matches string"] = responseBody.has("string_you_want_to_search");
~~~
例子：響應體包含以下字段 "path": "field is read-only",
~~~
tests["Body matches string"] = responseBody.has("field is read-only");
tests["Body matches string"] = responseBody.has("path");
~~~
4.轉換XML身體JSON對象
~~~
var jsonObject = xml2Json(responseBody);
~~~
5.檢查響應體等于一個字符串
~~~
tests["Body is correct"] = responseBody === "response_body_string";
~~~
6.檢查一個JSON值字段
~~~
var data = JSON.parse(responseBody);
tests["Your test name"] = data.value === 100;
~~~
7.Content-Type的存在（不區分大小寫檢查）
~~~
tests["Content-Type is present"] = postman.getResponseHeader("Content-Type"); //Note: the getResponseHeader() method returns the header value, if it exists.
~~~
8.Content-Type的存在（區分大小寫）
~~~
tests["Content-Type is present"] = responseHeaders.hasOwnProperty("Content-Type");
~~~
9.響應時間小于200ms的
~~~
tests["Response time is less than 200ms"] = responseTime < 200;
~~~
10.狀態代碼是
~~~
tests["Status code is 200"] = responseCode.code === 200;
tests["Status code is 404"] = responseCode.code === 404;
~~~
11.代號包含一個字符串
~~~
tests["Status code name has string"] = responseCode.name.has("Created");
~~~
例子：`Status：201 CREATED`
~~~
tests["Status code is 201"] = responseCode.code === 201;
tests["Status code name has string"] = responseCode.name.has("Created");
~~~
12.成功的POST請求的狀態代碼
~~~
tests["Successful POST request"] = responseCode.code === 201 || responseCode.code === 202;
~~~
13.使用TinyValidator的JSON數據
~~~
var schema = {
"items": {
"type": "boolean"
}
};
~~~
> var data1 = [true, false];
> var data2 = [true, 123];
> console.log(tv4.error);
> tests["Valid Data1"] = tv4.validate(data1, schema);
> tests["Valid Data2"] = tv4.validate(data2, schema);
