Where are the generated fixtures stored?

The skill writes the generated JSON files directly into the project's designated fixtures/ directories for immediate use.

What schemas does this skill support?

It currently targets CommandDTO and DecisionDTO schemas typically found in the contracts/schemas directory of the project.

Does it integrate with existing testing tools?

The generated fixtures are designed to be consumed by contract-checker and graph-sanity testing utilities.

Can it generate data for negative testing?

Yes, it specifically generates invalid scenarios including missing required fields, ambiguous shapes, and incorrect enum values.

安全与测试

Generates valid and invalid JSON test fixtures for Command and Decision DTOs based on current contract schemas.

关于

The Fixtures Generator skill automates the creation of canonical test data for contract validation and graph testing. By analyzing schema definitions for commands and decisions, it produces both minimal valid examples and purposefully invalid scenarios—such as missing required fields or incorrect payload shapes. This ensures that testing suites like contract-checker and graph-sanity have robust, up-to-date data to verify system integrity against evolving contract versions.

主要功能

Automated JSON fixture generation from schema definitions
Ensures test data stays synchronized with the latest schema versions
Support for both valid and expected-invalid test scenarios
Detects schema-breaking changes like missing fields or invalid enums
0 GitHub stars
Tailored for CommandDTO and DecisionDTO contract structures

使用场景

Generating negative test cases to verify robust error handling in API consumers.
Populating test suites with diverse edge-case data for contract validation.
Updating legacy test fixtures automatically after a schema version upgrade.
