Generates sets of data for fuzz testing.
npm install fuzzmaticGenerates sets of data for fuzz testing.
- Generates sets of valid and invalid data that can be used to test JavaScript/TypeScript functions and REST APIs.
- Generates data from a JSON schema.
- CLI tool:
- Input a JSON schema in JSON or YAML format.
- Outputs JSON format.
Install it:
``bash`
npm install -g fuzzmatic
Run it on a JSON schema:
`bash`
fuzzmatic a-json-schema.json
Run it on a JSON schema in YAML format:
`bash`
fuzzmatic a-json-schema.yaml
Generated data is output to the console.
Install it in your project:
`bash`
npm install fuzzmatic
Require it in your code:
`javascript`
const fuzzmatic = require("fuzzmatic");
Load your JSON schema and generate data from it:
`javascript
const fs = require("fs");
const schema = JSON.parse(fs.readFileSync("a-json-schema.json", "utf-8"));
const data = fuzzmatic.generateData(schema);
console.log(data);
`
If you want to load your JSON schema from a YAML file you need to install the YAML parser:
`bash`
npm install yaml
Then load and parse the YAML file, before generating data from it:
`javascript
const fs = require("fs");
const yaml = require("yaml");
const schema = yaml.parse(fs.readFileSync("a-json-schema.yaml", "utf-8"));
const data = fuzzmatic.generateData(schema);
console.log(data);
`
