Jest Integration Example

Detailed documentation on the Jest integration is available in the main Jazzer.js documentation.

Quickstart

To use the Jest integration install the @jazzer.js/jest-runner package and configure it as a dedicated test runner in package.json.

The example below shows how to configure the Jazzer.js Jest integration in combination with the normal Jest runner.

"jest": {
  "projects": [
    {
      "displayName": "test"
    },
    {
      "runner": "@jazzer.js/jest-runner",
      "displayName": {
        "name": "Jazzer.js",
        "color": "cyan"
      },
      "testMatch": [
        "<rootDir>/**/*.fuzz.js"
      ]
    }
  ]
}

Further configuration can be specified in .jazzerjsrc.json in the following format:

{
	"includes": ["*"],
	"excludes": ["node_modules"],
	"customHooks": [],
	"fuzzerOptions": [],
	"sync": false
}

Write a fuzz test like:

// file: jazzerjs.fuzz.js
describe("My describe", () => {
	it.fuzz("My fuzz test", (data) => {
		target.fuzzMe(data);
	});
});
