🐐 goat  

goat (Go API Tester) is a CLI tool to simplify and automate integration testing of HTTP APIs by using human writable, readable, reusable and committable script files.

Example Goatfile

use util/login

### Setup

POST {{.instance}}/api/v1/auth/login

[Header]
Content-Type: application/json

[Body]
{ 
    "username": "{{.username}}",
    "password": "{{.password}}"
}

[Script]
assert_eq(response.StatusCode, 200, "non-ok status code");

---

### Tests

GET {{.instance}}/api/v1/list

[Script]
assert(response.StatusCode >= 400, `Status code was ${response.StatusCode}`);
print(response.Body);

This tool is very much inspired by Hurl. Please give them a visit and evaluate what fits best for you.

But why?

goat has some advantages versus common tools like Postman or Insomnia.

• Write your API tests in easy to read and write, simple text files.
• Build easy to reproduce end-to-end tests which you can directly commit with your source code.
• Build for being used headlessly in CI/CD systems.
• Easy to install due to being one single, self contained binary.
• Goatfiles can be read, written and understood using any type of text editor.
• High level of flexibility due to the usage of a micro script engine (JavaScript) for assertions.
• Scripts can be imported and executed by other scripts to reduce code duplication.
• Supports custom HTTP methods, status codes and headers.

Getting Started

Installation

If you have the Go toolchain installed, you can simply install the tool via go install.

go install github.com/studio-b12/goat/cmd/goat@latest

Otherwise, you can also download the binaries from the Releases Page.

Goatfile

Now, you can dive in to create your first Goatfile. You can find more information on how Goatfiles work in the documentation book.

You can also simply generate an example Goatfile using the following command.

goat --new

There, you can define your setup, teardown and test requests as you desire.

Take a look into the more detailed CLI Manual to find out more.

Language Support

There is currently a very early prototype extension for Visual Studio Code adding syntax highlighting for Goatfiles. here you can find more informations about that: https://github.com/studio-b12/goat-vscode.
