用 k6 测试 ASP.net 核心应用程序加载: 实际操作

Tuesday, 02 December 2025

既然您了解 k6 和性能测试的基本原理, 现在是时候将这种知识付诸实践了。文章通过写写真实的测试, 将其纳入 CI/ CD 管道, 并使用剖析工具来识别和解决性能瓶颈。

这是 第二部分第二部分 k6 载荷测试的两部分系列:

**第1部分:导言**k6入门,安装,测试类型,以及为什么K6入门
**第2部分(本条)**写作测试、CI/CD集成、特征分析和现实世界实例

如果您还没有读过第一部分, 请先从那里开始了解 k6 基础、安装和测试类型, 然后跳入执行阶段。

设置您的测试环境

在运行 k6 测试之前, 我们设置最小的 Blog 用于测试 :

1. 本地运行最小浏览量

使用演示项目 :

cd Mostlylucid.MinimalBlog.Demo
dotnet run

或使用 Docker :

docker run -d -p 5000:8080 \
  -v $(pwd)/Markdown:/app/Markdown \
  --name minimalblog-test \
  scottgal/minimalblog:latest

为什么释放模式用于性能测试的事项

准确性能测试 总是以释放模式构建:

dotnet run --configuration Release

除错对释放模式差异 :

|--------|------------|--------------| | 优化禁用 # 完全 JIT 优化启用 # | 内衬最起码的侵略性方法内衬 | 死代码 | 除调符号 完整 PDB, 额外元数据 : 最小或零 : | 发发发价 | Debug.Assert() 正在编译 | 检查伤口 额外的安全检查优化到安全的地方 | 典型间接费用 * 2-10x慢 * 基线业绩 *

为何调试模式产生误导结果:

无 JIT 优化:汇编器保存调试代码结构,而不是优化速度
附加仪表仪表:调试构建包括断点代码、可变检查和堆叠痕迹
无内衬方法没有嵌入 , 添加在生产中不存在的呼叫管理费
发售运行: Debug.Assert() 执行对数,添加生产时没有的检查
不同的内存模式:调试分配包括影响到GC行为的铺垫和跟踪

何时使用调试模式测试 :

排除问题失败:当测试失败时,您需要详细的堆叠痕迹
调查具体请求:附加调试器以追踪单一有问题的请求
正在核查日志记录:确保您的伐木记录捕捉到装载中的正确信息
初始发展:在撰写新的测试脚本并核实其击中右端点时

建议的工作流程:

# 1. Develop and debug with Debug mode
dotnet run                           # Debug mode (default)

# 2. Validate functionality works
k6 run --vus 1 --duration 10s smoke-test.js

# 3. Switch to Release for actual performance testing
dotnet run -c Release

# 4. Run full load tests
k6 run load-test.js

拇指规则如果您正在测量性能, 请使用释放。如果您正在修补错误, 请使用 Debug 。

2. 准备试验数据

创建用于测试的多个标记降位站点 :

# Create test posts directory
mkdir -p TestMarkdown

# Create sample posts
for i in {1..10}; do
  cat > TestMarkdown/test-post-$i.md <<EOF
# Test Post $i




This is test post number $i with some **bold** text and *italic* text.

## Sample Content

- Item 1
- Item 2
- Item 3

\`\`\`csharp
public class Test {
    public int Value { get; set; }
}
\`\`\`
EOF
done

3. 创建测试脚本目录

mkdir k6-tests
cd k6-tests

现在我们准备写测试报告了!

试验1:烟雾试验

让我们从简单的烟雾测试开始来验证基本功能:

文件 : smoke-test.js

import http from 'k6/http';
import { check, sleep } from 'k6';

export const options = {
  vus: 1,
  duration: '30s',
  thresholds: {
    http_req_duration: ['p(95)<500'], // 95% of requests should be below 500ms
    http_req_failed: ['rate<0.01'],    // Less than 1% errors
  },
};

const BASE_URL = __ENV.BASE_URL || 'http://localhost:5000';

export default function() {
  // Test homepage
  let response = http.get(`${BASE_URL}/`);
  check(response, {
    'homepage status is 200': (r) => r.status === 200,
    'homepage has content': (r) => r.body.length > 0,
    'homepage response time OK': (r) => r.timings.duration < 500,
  });

  sleep(1);

  // Test a single post
  response = http.get(`${BASE_URL}/post/test-post-1`);
  check(response, {
    'post status is 200': (r) => r.status === 200,
    'post has content': (r) => r.body.length > 0,
    'post contains title': (r) => r.body.includes('Test Post 1'),
  });

  sleep(1);

  // Test categories page
  response = http.get(`${BASE_URL}/categories`);
  check(response, {
    'categories status is 200': (r) => r.status === 200,
    'categories has content': (r) => r.body.length > 0,
  });

  sleep(1);

  // Test category filter
  response = http.get(`${BASE_URL}/category/Testing`);
  check(response, {
    'category filter status is 200': (r) => r.status === 200,
    'category has posts': (r) => r.body.includes('Test Post'),
  });
}

运行测试 :

k6 run smoke-test.js

预期产出:

     ✓ homepage status is 200
     ✓ homepage has content
     ✓ homepage response time OK
     ✓ post status is 200
     ✓ post has content
     ✓ post contains title
     ✓ categories status is 200
     ✓ categories has content
     ✓ category filter status is 200
     ✓ category has posts

     checks.........................: 100.00% ✓ 300  ✗ 0
     data_received..................: 1.2 MB  40 kB/s
     data_sent......................: 15 kB   500 B/s
     http_req_duration..............: avg=45ms min=12ms med=38ms max=156ms p(95)=98ms
     http_reqs......................: 120     4/s

试验2:缓存校验试验

MinimalBlog的性能很大程度上取决于缓存。

文件 : cache-test.js

import http from 'k6/http';
import { check, group } from 'k6';

export const options = {
  vus: 1,
  iterations: 10,
};

const BASE_URL = __ENV.BASE_URL || 'http://localhost:5000';

export default function() {
  group('Memory Cache Test - First Request', () => {
    const start = Date.now();
    const response = http.get(`${BASE_URL}/post/test-post-1`);
    const duration = Date.now() - start;

    check(response, {
      'first request successful': (r) => r.status === 200,
    });

    console.log(`First request: ${duration}ms`);
  });

  group('Memory Cache Test - Cached Request', () => {
    const start = Date.now();
    const response = http.get(`${BASE_URL}/post/test-post-1`);
    const duration = Date.now() - start;

    check(response, {
      'cached request successful': (r) => r.status === 200,
      'cached request is faster': (r) => r.timings.duration < 100,
    });

    console.log(`Cached request: ${duration}ms`);
  });

  group('Output Cache Headers', () => {
    const response = http.get(`${BASE_URL}/post/test-post-1`);

    check(response, {
      'has cache headers': (r) => r.headers['Cache-Control'] !== undefined,
      'output cache working': (r) => {
        const age = r.headers['Age'];
        return age !== undefined && parseInt(age) >= 0;
      },
    });

    console.log(`Cache-Control: ${response.headers['Cache-Control']}`);
    console.log(`Age: ${response.headers['Age']}`);
  });
}

运行测试 :

k6 run cache-test.js

本次测试将显示:

第一次请求时间( 缓存冷时)
事后请求时间(缓缓热)
缓存信头校验

试验3:负载试验

现在让我们在现实的载荷下测试:

文件 : load-test.js

import http from 'k6/http';
import { check, sleep } from 'k6';
import { Rate } from 'k6/metrics';

// Custom metrics
const errorRate = new Rate('errors');

export const options = {
  stages: [
    { duration: '2m', target: 10 },   // Ramp up to 10 users
    { duration: '5m', target: 10 },   // Stay at 10 users
    { duration: '2m', target: 0 },    // Ramp down to 0
  ],
  thresholds: {
    http_req_duration: ['p(95)<300'],  // 95% under 300ms
    http_req_failed: ['rate<0.01'],     // Less than 1% errors
    errors: ['rate<0.1'],               // Less than 10% errors
  },
};

const BASE_URL = __ENV.BASE_URL || 'http://localhost:5000';

const scenarios = [
  { weight: 50, path: '/' },                    // 50% homepage
  { weight: 30, path: '/post/test-post-1' },    // 30% specific post
  { weight: 10, path: '/categories' },          // 10% categories
  { weight: 10, path: '/category/Testing' },    // 10% category filter
];

function weightedChoice(scenarios) {
  const total = scenarios.reduce((sum, s) => sum + s.weight, 0);
  let random = Math.random() * total;

  for (const scenario of scenarios) {
    random -= scenario.weight;
    if (random <= 0) return scenario;
  }

  return scenarios[0];
}

export default function() {
  const scenario = weightedChoice(scenarios);
  const response = http.get(`${BASE_URL}${scenario.path}`);

  const success = check(response, {
    'status is 200': (r) => r.status === 200,
    'response time OK': (r) => r.timings.duration < 500,
    'has content': (r) => r.body.length > 0,
  });

  errorRate.add(!success);

  sleep(Math.random() * 2 + 1); // Random sleep 1-3 seconds
}

运行测试 :

k6 run load-test.js

解释结果:

scenarios: (100.00%) 1 scenario, 10 max VUs, 9m30s max duration
  default: 2m00s ramp-up, 5m00s plateau, 2m00s ramp-down

     ✓ status is 200
     ✓ response time OK
     ✓ has content

     checks.........................: 100.00% ✓ 3450  ✗ 0
     data_received..................: 12 MB   22 kB/s
     data_sent......................: 132 kB  244 B/s
     errors.........................: 0.00%   ✓ 0     ✗ 1150
     http_req_duration..............: avg=42ms min=8ms med=35ms max=245ms p(95)=86ms p(99)=156ms
     http_reqs......................: 1150    2.12/s
     iteration_duration.............: avg=2.1s min=1.0s med=2.0s max=3.4s
     vus............................: 10      min=0   max=10

要观察的关键度量 :

http_req_du期限p(95):95%的响应时间(应低于阈值)
http_req_failed:错误率(应接近0%)
http_reqs http_reqs:总吞吐量

试验4:压力测试

让我们找到最小的 Blog 断点 :

文件 : stress-test.js

import http from 'k6/http';
import { check, sleep } from 'k6';

export const options = {
  stages: [
    { duration: '2m', target: 10 },    // Normal load
    { duration: '2m', target: 50 },    // Increase to 50
    { duration: '2m', target: 100 },   // Stress at 100
    { duration: '2m', target: 200 },   // High stress at 200
    { duration: '3m', target: 0 },     // Recovery
  ],
  thresholds: {
    http_req_duration: ['p(99)<3000'], // 99% under 3s even under stress
  },
};

const BASE_URL = __ENV.BASE_URL || 'http://localhost:5000';

export default function() {
  const responses = http.batch([
    ['GET', `${BASE_URL}/`],
    ['GET', `${BASE_URL}/post/test-post-1`],
    ['GET', `${BASE_URL}/post/test-post-2`],
    ['GET', `${BASE_URL}/categories`],
  ]);

  responses.forEach((response, index) => {
    check(response, {
      [`request ${index} status is 200`]: (r) => r.status === 200,
    });
  });

  sleep(0.5);
}

export function handleSummary(data) {
  return {
    'stress-test-summary.json': JSON.stringify(data),
    stdout: textSummary(data, { indent: ' ', enableColors: true }),
  };
}

运行测试 :

k6 run stress-test.js

监视 :

反应时间何时开始降低?
在VU计算什么时会出现错误吗 ?
系统在负载减少后是否恢复?

试验5:斯派试验

测试性突发交通高峰(比如在Reddit或Hacker News上出现):

文件 : spike-test.js

import http from 'k6/http';
import { check } from 'k6';

export const options = {
  stages: [
    { duration: '1m', target: 10 },    // Normal traffic
    { duration: '30s', target: 200 },  // Sudden spike!
    { duration: '3m', target: 200 },   // Sustained spike
    { duration: '1m', target: 10 },    // Back to normal
    { duration: '1m', target: 0 },     // Ramp down
  ],
  thresholds: {
    http_req_duration: ['p(95)<1000'], // Allow higher latency during spike
    http_req_failed: ['rate<0.05'],     // Allow 5% errors during spike
  },
};

const BASE_URL = __ENV.BASE_URL || 'http://localhost:5000';

export default function() {
  const response = http.get(`${BASE_URL}/`);

  check(response, {
    'status is 200 or 503': (r) => r.status === 200 || r.status === 503,
  });
}

运行测试 :

k6 run spike-test.js

本测试核实 :

系统能处理突如其来的负载吗?
是否有适当的税率限制机制?
它是否优雅地恢复了?

试验6:软体试验

探测内存泄漏或资源耗竭的长期测试:

文件 : soak-test.js

import http from 'k6/http';
import { check, sleep } from 'k6';

export const options = {
  stages: [
    { duration: '2m', target: 20 },    // Ramp up
    { duration: '3h', target: 20 },    // Stay at 20 for 3 hours
    { duration: '2m', target: 0 },     // Ramp down
  ],
  thresholds: {
    http_req_duration: ['p(95)<500'],
    http_req_failed: ['rate<0.01'],
  },
};

const BASE_URL = __ENV.BASE_URL || 'http://localhost:5000';

export default function() {
  const response = http.get(`${BASE_URL}/post/test-post-${Math.floor(Math.random() * 10) + 1}`);

  check(response, {
    'status is 200': (r) => r.status === 200,
    'response time stable': (r) => r.timings.duration < 500,
  });

  sleep(2);
}

运行测试 :

k6 run soak-test.js

重要:在浸泡试验期间监测系统资源:

# In another terminal
watch -n 5 'dotnet-counters ps | grep -i minimal'

# Or use top/htop
htop -p $(pgrep -f MinimalBlog)

监视 :

渐进内存增加( 模拟泄漏)
CPU使用量逐渐增加
反应时间随时间变化的降解

测试7:现实用户旅程

模拟实际用户行为 :

文件 : user-journey-test.js

import http from 'k6/http';
import { check, group, sleep } from 'k6';
import { htmlReport } from 'https://raw.githubusercontent.com/benc-uk/k6-reporter/main/dist/bundle.js';

export const options = {
  vus: 10,
  duration: '5m',
  thresholds: {
    'group_duration{group:::01_homepage}': ['avg<500'],
    'group_duration{group:::02_browse_posts}': ['avg<500'],
    'group_duration{group:::03_categories}': ['avg<500'],
  },
};

const BASE_URL = __ENV.BASE_URL || 'http://localhost:5000';

export default function() {
  // Simulate a real user journey

  group('01_homepage', () => {
    const response = http.get(`${BASE_URL}/`);
    check(response, {
      'homepage loaded': (r) => r.status === 200,
      'homepage has posts': (r) => r.body.includes('Test Post'),
    });
    sleep(Math.random() * 3 + 2); // Read homepage 2-5 seconds
  });

  group('02_browse_posts', () => {
    // User clicks on a post
    let response = http.get(`${BASE_URL}/post/test-post-1`);
    check(response, {
      'post loaded': (r) => r.status === 200,
      'post has content': (r) => r.body.length > 500,
    });
    sleep(Math.random() * 20 + 10); // Read post 10-30 seconds

    // User clicks another post
    response = http.get(`${BASE_URL}/post/test-post-2`);
    check(response, {
      'second post loaded': (r) => r.status === 200,
    });
    sleep(Math.random() * 15 + 5); // Read second post 5-20 seconds
  });

  group('03_categories', () => {
    // User explores categories
    const response = http.get(`${BASE_URL}/categories`);
    check(response, {
      'categories loaded': (r) => r.status === 200,
    });
    sleep(2);

    // User clicks a category
    const categoryResponse = http.get(`${BASE_URL}/category/Testing`);
    check(categoryResponse, {
      'category posts loaded': (r) => r.status === 200,
      'category has posts': (r) => r.body.includes('Test Post'),
    });
    sleep(Math.random() * 10 + 5); // Browse category 5-15 seconds
  });
}

export function handleSummary(data) {
  return {
    'user-journey-report.html': htmlReport(data),
  };
}

运行测试 :

k6 run user-journey-test.js

生成 HTML 报告 : user-journey-report.html

高级:测试MetaWeblog API

如果您已启用MetaWeblog, 请也测试它 :

文件 : metaweblog-test.js

import http from 'k6/http';
import { check } from 'k6';
import encoding from 'k6/encoding';

export const options = {
  vus: 1,
  iterations: 10,
};

const BASE_URL = __ENV.BASE_URL || 'http://localhost:5000';
const USERNAME = __ENV.USERNAME || 'admin';
const PASSWORD = __ENV.PASSWORD || 'changeme';

function createXmlRpcRequest(methodName, params) {
  return `<?xml version="1.0"?>
<methodCall>
  <methodName>${methodName}</methodName>
  <params>
    ${params}
  </params>
</methodCall>`;
}

export default function() {
  // Test getRecentPosts
  const recentPostsXml = createXmlRpcRequest('blogger.getRecentPosts', `
    <param><value><string>0</string></value></param>
    <param><value><string>${USERNAME}</string></value></param>
    <param><value><string>${PASSWORD}</string></value></param>
    <param><value><int>10</int></value></param>
  `);

  const response = http.post(`${BASE_URL}/metaweblog`, recentPostsXml, {
    headers: { 'Content-Type': 'text/xml' },
  });

  check(response, {
    'MetaWeblog API responds': (r) => r.status === 200,
    'MetaWeblog returns XML': (r) => r.body.includes('<?xml'),
    'MetaWeblog has methodResponse': (r) => r.body.includes('methodResponse'),
  });
}

运行测试 :

k6 run -e USERNAME=admin -e PASSWORD=yourpassword metaweblog-test.js

在 CI/ CD 中运行测试

使用 k6 作为质量门

K6在CI/CD中最有力的使用K6 质量门 在 GitHub Action 中执行全面 K6 测试的方法。

CI/CD k6测试最佳做法

快速启动, 提前出门
- 先进行烟雾测试(30秒)
- 只有在烟雾通过时才进行全面测试
- 无法快速保存 CI 分钟
使用适当的阈值

javascript // Too strict for CI thresholds: { http_req_duration: ['p(95)<100'] }

用 k6 测试 ASP.net 核心应用程序加载: 实际操作

设置您的测试环境

1. 本地运行最小浏览量

为什么释放模式 用于性能测试的事项

2. 准备试验数据

3. 创建测试脚本目录

试验1:烟雾试验

试验2:缓存校验试验

试验3:负载试验

试验4:压力测试

试验5:斯派试验

试验6:软体试验

测试7:现实用户旅程

高级:测试MetaWeblog API

在 CI/ CD 中运行测试

使用 k6 作为质量门
