rapidtest 0.4.0

A comprehensive testing framework for REST APIs with functional and performance testing capabilities

RapidTest

A lightweight library for REST API testing with functional checks, ASGI direct mode, fake data generation, and basic performance testing.

Features

• Simple HTTP testing with GET, POST, PUT, PATCH, DELETE
• Built-in response validation (status, JSON body, required keys)
• ASGI direct mode for testing app instances without running an HTTP server
• Fake data generation with Faker
• Basic load testing with concurrent users (threading + requests)
• Test any endpoint with just one line of code

Installation

pip install rapidtest

Quick Start (HTTP mode)

from rapidtest import Test, StatusCode

api = Test(url="http://localhost:8000")

# GET with status + key validation
api.get(
    path="/health",
    status=StatusCode.OK_200,
    keys=["message"]
)

# POST with request body + expected response body
payload = {"username": "hector", "password": "secret"}
api.post(
    path="/login",
    json=payload,
    status=StatusCode.OK_200,
    keys=["token"]
)

Quick Start (ASGI mode)

Use this when you want to test your ASGI app directly (for example FastAPI) without network overhead.

from fastapi import FastAPI
from rapidtest import Test, StatusCode

app = FastAPI()

@app.get("/ping")
def ping():
    return {"ok": True}

tester = Test(app=app, asgi_mode=True)

tester.get(
    path="/ping",
    status=StatusCode.OK_200,
    json={"ok": True}
)

Data Generation

from rapidtest import data

auth = data.generate_auth_user()

print(auth)  # {"username": "...", "password": "..."}

Useful helpers include:

• generate_name()
• generate_email()
• generate_phone()
• more..

Performance Testing

from rapidtest import Performance

perf = Performance(
    base_url="http://localhost:8000",
    users=20,
    duration=15,
    timeout=10
)

perf.add_get_task(endpoint="/health")
results = perf.run()

Returned metrics:

• total_requests
• successful_requests
• failed_requests
• success_rate
• avg_response_time
• min_response_time
• max_response_time
• requests_per_second
• duration
• users

Requirements

• Python >=3.7
• requests>=2.25.1
• faker>=13.0.0
