Open Source API Testing Tool: Validate HTTP Responses and Generate Reports in Markdown and Other Formats – An Alternative to Postman!

IntroductionA command-line based API testing tool that supports HTTP response validation and generates test reports in Markdown and other formats. An alternative to Postman!!!

API Testing is an open-source interface testing tool based on YAML files, which can run both locally and on the server.

When choosing a tool, there are many aspects to consider and compare. The following points highlight the features or advantages of this tool:

• Open Source: atest adopts the MIT open-source license, one of the most popular permissive open-source licenses. Some tools may have rich features and beautiful interfaces, but compared to open-source projects, free tools may suddenly become paid; moreover, your user experience is often hard to directly feedback into the product, leaving you to passively accept changes.
• Quality and Reliability: As a tool for testing scenarios, atest has a unit test coverage of 89%, with unit test code and business logic code being equally substantial. Additionally, every code change must pass through code scanning, unit testing, and other pipelines.
• Compact Size: The entire tool is only 18MB and supports Windows, Linux, and macOS platforms.
• Only a simple executable binary file, unlike some tools that install mysterious system startup items and services on your operating system.
• Based on YAML files, once submitted to a Git repository, it naturally supports team collaboration without the need to register additional accounts.
• Provides both simple and advanced modes for return value assertions, including JSON Schema and validation for Kubernetes resources.
• Supports performance testing.
• Can trigger the execution of individual or entire test files directly in VS Code.

Features

• Supported Protocols: HTTP, gRPC, tRPC
• Supports exporting test results in various formats: Markdown, HTML, PDF, Stdout
• Easy-to-use Mock service, supports OpenAPI
• Supports conversion to JMeter file format
• Supports response body field checks or eval
• Uses [JSON schema] to validate response parameters (https://json-schema.org/)
• Supports pre-processing and post-processing of API requests
• Can run in server mode and supports gRPC and HTTP endpoints
• VS Code extension support
• Github extension support
• Supports various storage methods (Local, ORM Database, S3, Git, Etcd, etc.)
• HTTP API record
• Supports multiple installation methods (CLI, Container, Native-Service, Operator, Helm, etc.)
• Integrates with Prometheus and SkyWalking for monitoring

Using in Docker

To run <span>atest</span> in server mode in Docker, you can access the UI console of <span>atest</span> via <span>8080</span>:

docker run --pull always -p 8080:8080 ghcr.io/linuxsuren/api-testing:master

Using <span>atest-collector</span> in Docker:

docker run -p 1234:8080 -v /var/tmp:/var/tmp \  ghcr.io/linuxsuren/api-testing atest-collector \  --filter-path /api \  -o /var/tmp/sample.yaml# you could find the test cases file from /var/tmp/sample# cat /var/tmp/sample
