Usage

Basic usage

package main

import (
    "context"
    "fmt"

    "github.com/benchttp/engine/benchttp"
)

func main() {
    report, _ := benchttp.
        DefaultRunner(). // Default runner with safe configuration
        WithNewRequest("GET", "http://localhost:3000", nil). // Attach request
        Run(context.Background()) // Run benchmark, retrieve report

    fmt.Println(report.Metrics.ResponseTimes.Mean)
}

Usage with JSON config via configio

package main

import (
    "context"
    "fmt"

    "github.com/benchttp/engine/benchttp"
    "github.com/benchttp/engine/configio"
)

func main() {
    // JSON configuration obtained via e.g. a file or HTTP call
    jsonConfig := []byte(`
{
  "request": {
    "url": "http://localhost:3000"
  }
}`)

    // Instantiate a base Runner (here the default with a safe configuration)
    runner := benchttp.DefaultRunner()

    // Parse the json configuration into the Runner
    _ = configio.UnmarshalJSONRunner(jsonConfig, &runner)

    // Run benchmark, retrieve report
    report, _ := runner.Run(context.Background())

    fmt.Println(report.Metrics.ResponseTimes.Mean)
}
