Postman常用测试脚本

状态码验证

// 验证状态码=200
pm.test("Status code is 200", function () {pm.response.to.have.status(200);
});

响应时间验证

// 验证响应时间<500ms
pm.test("Response time is within acceptable range", function () {pm.expect(pm.response.responseTime).to.be.below(500);
});

响应主体验证

// 验证响应body包含预期值
pm.test("Response body contains expected data", function () {pm.expect(pm.response.text()).to.include("expected_value");
});

JSON响应验证

// 验证响应是否有效json
pm.test("Response is valid JSON", function () {pm.expect(pm.response.json()).to.be.an("object");
});

请求头验证

// 验证请求包含请求头
pm.test("Header is present in the response", function () {pm.response.to.have.header("header_name");
});

链接测试

pm.test("Chaining multiple assertions", function () {pm.expect(pm.response.json().property1).to.eql("value1");pm.expect(pm.response.json().property2).to.eql("value2");
});

动态数据验证

pm.test("Dynamic data validation", function () {pm.expect(pm.response.json().user_id).to.eql(pm.environment.get("user_id"));
});

从环境变量设置数据

var jsonData = pm.response.json();
pm.environment.set("companyIdToDelete", jsonData.data._id);

响应结构验证

pm.test("Response schema validation", function () {const schema = {"type": "object","properties": {"property1": { "type": "string" },"property2": { "type": "number" }}};pm.expect(tv4.validate(pm.response.json(), schema)).to.be.true;
});

动态响应验证

pm.test("Dynamic response validation", function () {var responseBody = pm.response.json();var dynamicValue = responseBody.dynamic_property;pm.expect(dynamicValue).to.equal(pm.variables.get("expected_dynamic_value"));
});

API版本验证

var apiVersion = "v2";
pm.test("API versioning validation", function () {pm.request.headers.add({ key: "Accept-Version", value: apiVersion });pm.sendRequest(function (response) {pm.expect(response.status).to.equal(200);pm.expect(response.json().version).to.equal(apiVersion);});
});

文件上传

// Test file upload
pm.test("File upload validation", function () {var formData = {file: {value: pm.globals.get("fileData"),options: {filename: "sample.txt",contentType: "text/plain"}}};pm.sendRequest({url: "https://api.example.com/upload",method: "POST",body: formData}, function (response) {pm.expect(response.status).to.equal(200);pm.expect(response.json().success).to.be.true;});
});

身份和授权验证

pm.test("Authentication and authorization", function () {var authToken = pm.environment.get("authToken");pm.request.headers.add({ key: "Authorization", value: "Bearer " + authToken });pm.sendRequest(function (response) {pm.expect(response.status).to.equal(200);pm.expect(response.json().authorized).to.be.true;});
});

数据提取和转换

pm.test("Data extraction and transformation", function () {var responseArray = pm.response.json().data;var transformedData = responseArray.map(function (item) {return {id: item.id,name: item.first_name + " " + item.last_name"};});pm.expect(transformedData[0].name).to.include("John");pm.environment.set("transformedData", JSON.stringify(transformedData));
});

会话管理

var sessionToken;pm.test("Login and session management", function () {// 提取登录会话tokensessionToken = pm.response.json().session_token;pm.environment.set("sessionToken", sessionToken);
});pm.test("Authenticated request using session token", function () {// 使用保存的会话请求pm.request.headers.add({ key: "Authorization", value: "Bearer " + sessionToken });pm.sendRequest(function (response) {pm.expect(response.status).to.equal(200);});
});

分页测试

pm.test("Pagination testing", function () {var response = pm.response.json();var currentPage = response.page;var totalPages = response.total_pages;pm.expect(currentPage).to.be.at.least(1);pm.expect(currentPage).to.be.at.most(totalPages);
});

负载测试

var concurrentRequests = 10;pm.test("Load testing", function () {var requests = [];for (var i = 0; i < concurrentRequests; i++) {requests.push(pm.sendRequest);}Promise.all(requests).then(function (responses) {responses.forEach(function (response) {pm.expect(response.status).to.equal(200);});});
});

数据库验证

var mockDatabase = [{ id: 1, name: "Item 1" },{ id: 2, name: "Item 2" }
];pm.test("Database validation", function () {var response = pm.response.json();mockDatabase.forEach(function (item) {var matchingItem = response.find(function (responseItem) {return responseItem.id === item.id;});pm.expect(matchingItem.name).to.equal(item.name);});
});
