Best Practices for Go Language API Performance Testing
Introduction
API performance testing is essential to ensure that the application Program reliability and scalability are critical. This article introduces the best practices for API performance testing using Go language, as well as a practical case.
Best practices for API performance testing using Go language
1. Choose the appropriate tool
-
HTTP client Library: Use libraries such as
http
ornet/http
. - Stress testing library: Vegeta, wrk2, hey and other tools can be used to simulate a large number of concurrent requests.
-
Monitoring tools: Use tools such as
pprof
orexpvar
to analyze server performance.
2. Well-defined test goals
- Identify the API endpoints to be tested.
- Set goals for expected response time, throughput, and error rate.
3. Use a real environment
- Run tests on a system that is as close to the production environment as possible.
- Includes authentication, database access and external dependencies.
4. Write real-world scenarios
- Create test scenarios that simulate real user behavior.
- Includes requests of different sizes, concurrent requests, and authentication tokens.
5. Perform browser and server monitoring
- Use a browser extension such as WebPageTest to measure client performance.
- Use
pprof
andexpvar
on the server to monitor CPU usage, memory usage, and request latency.
Practical case
Use Vegeta to simulate 100 concurrent request tests/users
API endpoint:
package main import ( "fmt" "log" "net/http" "os" "time" "github.com/tsenart/vegeta/v12/lib" ) func main() { // go run main.go "" target := vegeta.NewStaticTargeter(os.Args[1]) attack := vegeta.NewAttacker() var metrics vegeta.Metrics duration := 60 * time.Second for i := 0; i < 100; i++ { // 并发 100 个请求 resp, _, err := attack.Do(target) if err != nil { log.Fatal(err) } metrics.Add(resp) } rate := time.Duration(metrics.Requests) * time.Second / duration avgLatency := metrics.Latencies.Mean throughput := metrics.Throughput.Mean fmt.Printf("Rate: %.2f req/s\n", rate) fmt.Printf("Latency: %.2f ms\n", avgLatency/time.Millisecond) fmt.Printf("Throughput: %.2f kb/s\n", throughput) }
Conclusion
By following these best practices and using recommended tools, you can effectively perform Go language API performance testing. By conducting thorough testing, you can ensure that your application performs well in production.

Developers should follow the following best practices: 1. Carefully manage goroutines to prevent resource leakage; 2. Use channels for synchronization, but avoid overuse; 3. Explicitly handle errors in concurrent programs; 4. Understand GOMAXPROCS to optimize performance. These practices are crucial for efficient and robust software development because they ensure effective management of resources, proper synchronization implementation, proper error handling, and performance optimization, thereby improving software efficiency and maintainability.

We need to customize the error type because the standard error interface provides limited information, and custom types can add more context and structured information. 1) Custom error types can contain error codes, locations, context data, etc., 2) Improve debugging efficiency and user experience, 3) But attention should be paid to its complexity and maintenance costs.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
