Persistence of performance testing in Go language Integration and Delivery

When developing modern software, performance is critical. Performance testing is a necessary practice to verify the performance of an application in a production environment.

Continuous Integration (CI) and Continuous Delivery (CD) automate the software development and deployment process, enabling development teams to quickly and continuously deliver high-quality software.

Integrate performance testing in CI/CD

Integrating performance testing into your CI/CD pipeline ensures that potential performance issues are detected before new code is deployed. Here are some best practices:

• Early Integration: Add performance testing tasks early in the CI pipeline, such as after the automated tests have run.
• Automated testing: Use an automated testing framework (such as [httperf](https://github.com/httperf/httperf) or [wrk](https://github.com/ wg/wrk)) to write and run performance test cases.
• Collect metrics: Collect performance metrics from test cases such as response time, throughput, and error rate.
• Set thresholds: Set acceptance thresholds for performance indicators, and trigger alarms when these thresholds exceed standards.

Practical case

Consider a Web service developed using Go language. In order to integrate performance testing in the CI/CD pipeline, we can:

1. Use httperf Create performance test cases:

import (
    "fmt"
    "log"

    "github.com/httperf/httperf"
)

func main() {
    // 创建 HTTP 性能测试请求
    req := httperf.NewRequest("GET", "https://example.com/api/v1/users")
    req.AddHeader("Content-Type", "application/json")

    // 设置性能测试选项
    opts := httperf.Options{
        NumConnections: 10,     // 并发连接数
        Timeout:        10,     // 超时时间（秒）
        Duration:       60,     // 测试持续时间（秒）
        Rate:           100,    // 请求速率（次/秒）
        PrintInterval:  10,     // 打印结果的时间间隔（秒）
        OutputFile:     "test.log", // 保存结果的文件名
    }

    // 执行性能测试
    err := httperf.Run(req, opts)
    if err != nil {
        log.Fatal(err)
    }

    // 解析测试结果
    results, err := httperf.ParseResults("test.log")
    if err != nil {
        log.Fatal(err)
    }

    // 比较结果与阈值
    if results.MeanResponseTime > 500 { // 响应时间阈值 500 毫秒
        fmt.Printf("响应时间超标：%d 毫秒\n", results.MeanResponseTime)
    }
}

2. Use Jenkins or other CI/CD tools integrate test cases into CI pipelines.
3. Set assertions in the pipeline that compare performance metrics to thresholds.
4. If the test case fails, an alarm is triggered to notify the development team of potential performance issues.

By integrating performance testing into the CI/CD pipeline, we can ensure that applications always meet expected performance goals and proactively detect and resolve performance issues before they occur.
