Pre-request Script
get an environment variable
pm.environment.get(“variable_key”);
get an global variable
pm.globals.get(“variable_key”);
get an variable
pm.variables.get(“variable_key”);
set an environment variable(设置环境变量)
pm.environment.set(“variable_key”, “variable_value”);
set an global variable（设置全局变量）
pm.globals.set(“variable_key”, “variable_value”);
clear an environment variable
pm.environment.unset(“variable_key”);
clear an global variable
pm.globals.unset(“variable_key”);
send a request（通过url发送一个请求，并将返回结果打印出来）
pm.sendRequest(“https://postman-echo.com/get”, function (err, response) {
console.log(response.json());
});
Tests
status code:code is 200（通过相应状态判断响应是否正常）
pm.test(“Status code is 200”, function () {
pm.response.to.have.status(200);
});
Response Body:contains string（响应体是否包含某个期望的字符串，实际就是关键词）
pm.test(“Body matches string”, function () {
pm.expect(pm.response.text()).to.include(“string_you_want_to_search”);
});
Response Body:json value check（响应体json里面是否包含期望的值）
pm.test(“Your test name”, function () {
var jsonData = pm.response.json();
pm.expect(jsonData.value).to.eql(100);
});
Response Body:is equal to a string（判断返回内容是否跟预期完全相等。）
pm.test(“Body is correct”, function () {
pm.response.to.have.body(“response_body_string”);
});
Response headers:Content-type header check（响应头是否包含content-type header）
pm.test(“Content-Type is present”, function () {
pm.response.to.have.header(“Content-Type”);
});
Response time is less than 200ms(响应时间不超过多长)
pm.test(“Response time is less than 200ms”, function () {
pm.expect(pm.response.responseTime).to.be.below(200);
});
Status code:successful post request（判断post是否请求成功，请求成功的response code包含201、202）
pm.test(“Successful POST request”, function () {
pm.expect(pm.response.code).to.be.oneOf([201,202]);
});
Status code:no name has string
pm.test(“Status code name has string”, function () {
pm.response.to.have.status(“Created”);
});
response body:convert xml body to a json object（将xml内容转换成json）
var jsonObject = xml2Json(responseBody);
use tiny validator for json data（验证json数据是否正确）
var schema = {
“items”: {
“type”: “boolean”
}
};
var data1 = [true, false];
var data2 = [true, 123];
pm.test(‘Schema is valid’, function() {
pm.expect(tv4.validate(data1, schema)).to.be.true;
pm.expect(tv4.validate(data2, schema)).to.be.true;
});
将响应体的数据转化为json格式
var jsonData = pm.response.json();
pm.environment.set(“token”,jsonData.result.json[‘token’]);
或者pm.environment.set(“token”,jsonData.json[‘token’]);
