go-webpagetest

Simple, opionated wrapper for WebPagetest API and CLI (mostly as a test for wrapper itself)

Usage

Get it with:

go get -d -v github.com/olegfedoseev/go-webpagetest

And than in you code:

import  "github.com/olegfedoseev/go-webpagetest"

wpt, err := webpagetest.NewClient("https://webpagetest.org")
if err != nil {
  log.Fatalf("Failed to create client: %v", err)
}

result, err := wpt.RunTest(webpagetest.TestSettings{
  URL:      "https://google.com",
  Location: "Frankfurt_Ruxit:Chrome",
  Runs:     3,
  ScreenWidth:  1280,
  ScreenHeight: 720,
})
if err != nil {
  log.Fatalf("Error: %v", err)
}
fmt.Printf("Result: %#v", result)

Or you can look at source code of CLI at cmd/main.go

TestStep is struct with information of one particular test "run"

type TestView 

type TestView struct {
	Run           int        `json:"run"`
	Tester        string     `json:"tester"`
	NumberOfSteps int        `json:"numSteps"`
	Steps         []TestStep `json:"steps"`
}

TestView struct tries to combine to kinds of testViews than WebPagetest returns With Steps in case of scripted run and without steps, when we test single url Because Go is strictly typed, we have to "merge" them in one data type

func (tv *TestView) UnmarshalJSON(b []byte) error

UnmarshalJSON implements custom unmarshaling logic than mitigates "dynamic" nature of test result's json
