## What is EvoMaster?

EvoMaster is an AI-driven tool that automatically generates system-level test cases for web and enterprise applications. The tool specializes in fuzzing Web APIs, including REST, GraphQL, and RPC protocols such as gRPC and Thrift.

The tool operates in both black-box and white-box testing modes, with enhanced capabilities for JVM-based applications in white-box mode. It utilizes evolutionary algorithms and dynamic program analysis to create comprehensive test suites.

EvoMaster generates test cases in multiple formats including JUnit, Python, and JavaScript. The tool can detect application faults and create regression test suites to maintain code quality over time.

The tool handles complex scenarios including SQL database interactions and authentication mechanisms. It supports OpenAPI/Swagger schemas for REST API testing, enabling structured and specification-driven test generation.

In white-box mode, EvoMaster performs bytecode analysis and applies testability transformations to improve test effectiveness. The tool focuses on improving code coverage and identifying vulnerabilities through systematic testing approaches.
