Can I configure load testing parameters like concurrent users?

Yes, the skill allows you to specify thread counts, ramp-up time, and loop iterations during the generation process to match your performance testing requirements.

Are the generated JMX files compatible with standard JMeter?

The scripts are generated in standard JMX XML format and are compatible with Apache JMeter version 5.0 and above.

How do I handle authentication headers?

The generator parses headers like 'Authorization' and 'Content-Type' directly from your input documentation, curl commands, or Postman collection and includes them in the JMeter Header Manager.

What input formats are supported by api2jmx?

It supports OpenAPI 3.0, Swagger 2.0 (JSON/YAML), Markdown documentation, Postman collections (v2.1), curl commands, and raw HTTP requests.

Does it automatically generate test assertions?

Yes, it includes response status code assertions (defaulting to 200) and can generate JSON path assertions if the response schema is provided in the input.

Security & Testing

Converts API documentation, curl commands, and Postman collections into executable Apache JMeter JMX test scripts automatically.

This skill empowers developers and QA engineers to rapidly create performance and functional test plans for Apache JMeter without manual XML editing. By parsing various inputs like OpenAPI/Swagger specs, Markdown documentation, raw HTTP requests, or curl commands, it generates fully structured JMX files complete with thread groups, HTTP samplers, headers, and assertions. It is particularly useful for transitioning from API development to load testing, migrating Postman collections for high-concurrency stress testing, or quickly generating boilerplate test scripts from technical documentation.

Key Features

01Configures performance parameters like thread count, ramp-up time, and loops

02Converts Markdown API documentation and curl commands into JMX scripts

03Includes standard response assertions and variable parameterization support

04Automatically generates HTTP headers, query parameters, and JSON payloads

052 GitHub stars

06Supports OpenAPI 3.0, Swagger 2.0, and Postman Collection v2.1 formats

Use Cases

01Transforming a Swagger/OpenAPI specification into a baseline performance test suite

02Migrating Postman collections to JMeter for advanced concurrency and stress testing

03Converting curl commands or raw HTTP logs into a JMeter load testing plan
