Rest in Pytest (RiP)

---

Overview

Rest in Pytest (RiP) is a Python library designed for REST API testing. It simplifies the process of API testing by leveraging libraries such as pytest and httpx. Additionally, it offers a fluent interface design, inspired by Rest Assured, for constructing and executing HTTP requests, as well as validating responses.

Features

• Fluent interface for building HTTP requests
• Flexible request configuration (headers, params, data, SSL verification, etc.)
• Comprehensive response assertions
• Integration with pytest for easy test execution and reporting

Examples

These examples are based on the tests found in tests\test_rip.py.

GET request with parameters and expect a specific status code and JSON path in the response.

def test_get_resource(base_url):
    (
        Rip()
        .given()
        .url(base_url)
        .headers({"Content-Type": "application/json"})
        .params({"userId": 1})
        .when()
        .get("/posts")
        .then()
        .expect_status(200)
        .expect_header_content_type("application/json; charset=utf-8")
        .expect_json_path(
            "$..title",
            [
                "sunt aut facere repellat provident occaecati excepturi optio reprehenderit",
                "qui est esse",
                "ea molestias quasi exercitationem repellat qui ipsa sit aut",
                "eum et est occaecati",
                "nesciunt quas odio",
                "dolorem eum magni eos aperiam quia",
                "magnam facilis autem",
                "dolorem dolore est ipsam",
                "nesciunt iure omnis dolorem tempora et accusantium",
                "optio molestias id quia eum",
            ],
        )
        .expect_json_contains(
            {
                "userId": 1,
                "id": 1,
                "title": "sunt aut facere repellat provident occaecati excepturi optio reprehenderit",
                "body": "quia et suscipit\nsuscipit recusandae consequuntur expedita et cum\nreprehenderit molestiae ut ut quas totam\nnostrum rerum est autem sunt rem eveniet architecto",
            }
        )
    )

GET request using keyword arguments, providing a different approach to configuring the request.

def test_get_params(base_url):
    (
        Rip()
        .given(base_url)
        .when()
        .get(
            endpoint='/posts',
            headers={'Content-Type': 'application/json'},
            params={'userId': 1},
        )
        .then()
        .expect_status(200)
    )

POST request with JSON data and expect a specific status code and JSON content in the response.

def test_create_resource(base_url):
    (
        Rip()
        .given()
        .url(base_url)
        .headers({"Content-type": "application/json; charset=UTF-8"})
        .content('{"title": "foo", "body": "bar", "userId": 1}')
        .when()
        .post("/posts")
        .then()
        .expect_status(201)
        # Assert reponse in json
        .expect_json({"id": 101, "title": "foo", "body": "bar", "userId": 1})
        # Assert response content in unicode
        .expect_body(
            '{\n  "title": "foo",\n  "body": "bar",\n  "userId": 1,\n  "id": 101\n}'
        )
    )

PUT request with JSON data to update a resource and expect a specific status code in the response.

def test_update_resource(base_url):
    (
        Rip()
        .given()
        .url(base_url)
        .headers({"Content-type": "application/json; charset=UTF-8"})
        .json({"title": "foo", "body": "bar", "userId": 1})
        .when()
        .put("/posts/1")
        .then()
        .expect_status(200)
    )
