Pre-requisites

Usage

To recommended way is to integrate with Godog and Go test as specified in the Godog documentation

package main

import (
	"flag"
	"os"
	"testing"

	apicontext "github.com/brpaz/godog-api-context"
	"github.com/cucumber/godog"
)

var opts = godog.Options{
	Format:        "progress", // can define default values,
}

func init() {
	godog.BindFlags("godog.", flag.CommandLine, &opts)
}

func TestMain(m *testing.M) {
	flag.Parse()
	opts.Paths = flag.Args()

	apiContext := apicontext.New("<base_url>")

	status := godog.TestSuite{
		Name:                "godogs",
		ScenarioInitializer: apiContext.InitializeScenario,
		Options:             &opts,
	}.Run()

	if st := m.Run(); st > status {
		status = st
	}
	os.Exit(status)
}

You can see a complete example together with Feature files in examples folder.

Available step definitions

^I set query param "([^"]*)" with value "([^"]*)"$

^I set query params to:$

^I set header "([^"]*)" with value "([^"]*)"$

^I set headers to:$

^I send "([^"]*)" request to "([^"]*)" with form body::$

^I send "([^"]*)" request to "([^"]*)"$

^I send "([^"]*)" request to "([^"]*)" with body:$

^The response code should be (\d+)$

^The response should be a valid json$

^The response should match json:$

The response header "([^"]*)" should have value ([^"]*)$

^The response should match json schema "([^"]*)"$

^The json path "([^"]*)" should have value "([^"]*)"$

^wait for (\d+) seconds$

^Store data in scope variable "([^"]*)" with value ([^"]*)

^I store the value of response header "([^"]*)" as ([^"]*) in scenario scope$

^I store the value of body path "([^"]*)" as "([^"]*)" in scenario scope$

^The scenario variable "([^"]*)" should have value "([^"]*)"$

Scope Values

This can also store the values from http response body and header and then use in subsequent requests. To use the value of scope variable, use this pattern: `##(keyname)` without parenthesis

Example:

I store the value of response header "X-AUTH-TOKEN" as token in scenario scope
I set header "X-AUTH-TOKEN" with value "`##token`"

This can be used for Authentication headers.
