mutation-testing-report-schema
Advanced tools
The mutation-testing-report-schema npm package provides a schema for mutation testing reports. It is used to validate and ensure consistency in the format of reports generated by mutation testing tools. Mutation testing is a method of software testing where the source code is modified in small ways to test if the existing test cases can detect the changes.
Schema Validation
The mutation-testing-report-schema provides a JSON schema to validate mutation testing reports. This ensures that the reports adhere to a standard structure, making it easier to process and analyze them.
{ "type": "object", "properties": { "files": { "type": "object" }, "schemaVersion": { "type": "string" } }, "required": ["files", "schemaVersion"] }Consistent Report Structure
By using the schema, reports generated by different mutation testing tools can have a consistent structure. This example shows a simple report structure with a file containing mutants and their statuses.
{ "files": { "example.js": { "mutants": [ { "id": "1", "status": "Killed", "mutatorName": "StringLiteral" } ] } }, "schemaVersion": "1.0" }The mutation-testing-elements package provides web components to visualize mutation testing reports. While mutation-testing-report-schema focuses on the structure and validation of the reports, mutation-testing-elements is about rendering and displaying the reports in a user-friendly way.
Stryker is a mutation testing framework for JavaScript and TypeScript. It generates mutation testing reports that can be validated against the mutation-testing-report-schema. Stryker focuses on the generation and execution of mutation tests, whereas mutation-testing-report-schema is concerned with the report format.
