testpilot

testpilot

testpilot is a Go package that provides a testing framework for making HTTP requests and validating responses. It is designed to help create test plans and perform assertions on HTTP requests and responses.

Features

• Create and manage test plans for HTTP testing.
• Perform HTTP requests with customizable methods, URLs, headers, and body content.
• Validate HTTP responses with assertions on status codes, response body, and JSON paths.
• Cache and retrieve responses for later use in tests.

Installation

To install testpilot, run the following command:

go get github.com/trapajim/testpilot

Usage

Creating a Test Plan

Create a new test plan using the NewPlan function:

func TestYourFunction(t *testing.T) {
    p := NewPlan(t, "test")
    p.Request("GET", "https://api.sampleapis.com/futurama/episodes").
    Expect().
    Status(200).
    Body(AssertPath(".0.id", func(val int) error {
        if val != 1 {
            return errors.New("expected 1 got " + strconv.Itoa(val))
        }
        return nil
    }))
    p.Run()
}

Adding a body and headers to the request

You can add a body and headers to the request using the Body and Headers methods:

type Episode struct {
    Id int `json:"id"`
    Title string `json:"title"`
}
func TestYourFunction(t *testing.T) {
    newEpisode := Episode{
        Id: 1,
        Title: "Space Pilot 3000",
    }
    p := NewPlan(t, "test")
    p.Request("POST", "https://api.sampleapis.com/futurama/episodes").
    Body(JSON(newEpisode)).
    Headers(map[string]string{
        "Content-Type": "application/json",
    }).
    Expect().
    Status(201)
    p.Run()
}

Utilizing Placeholder

You can utilize placeholders in the URL of the request. Placeholders are defined using curly braces {} in the URL and should be a json path. The value of the placeholder is extracted from the response of the previous request.

func TestYourFunction(t *testing.T) {
    p := NewPlan(t, "test")
    p.Request("GET", "https://api.sampleapis.com/futurama/episodes").
    Expect().
    Status(200)
    // add a second request that uses the response of the first request as a placeholder
    p.Request("GET", "https://api.sampleapis.com/futurama/episodes/{.0.id}"). // the placeholder is the id of the first episode
    Expect().
    Status(200)
    p.Run()
}

Storing and Retrieving Responses

You can store the response of a request and retrieve it later in the test plan. This is useful when you want to use the response of a request in multiple assertions.

func TestYourFunction(t *testing.T) {
    p := NewPlan(t, "test")
    p.Request("GET", "https://api.sampleapis.com/futurama/episodes").
    Store("episodes"). // store the response of this request
    Expect().
    Status(200).
    
    // add a second request that uses the stored response
    p.Request("GET", "https://api.sampleapis.com/futurama/episodes/{.0.id}"). // the placeholder is the id of the first episode
    Expect().
    Status(200).

    // add a third request, this time using the stored response
    p.Request("GET", "https://api.sampleapis.com/futurama/episodes/{episodes.1.id}"). // starting the placeholder with the name of the stored response 
    Expect().
    Status(200)

	// run the test plan
    p.Run()
}

Responses can also be used in Body method with p.Response() or p.ResponseForKey("name"):

See tests for more comprehensive examples.
