pwtg

PWTG - PairWise Test Generator

This simple library is a wrapper for Microsoft's PICT tool.

Unlike some other packages this library does not include PICT binaries. User is expected to provide requested binary him/her self. This is primarily for security reasons. It is not a good practise to download npm packages with binaries inside.

Preconditions

• Node.js LTS
• downloaded or built binary for your OS - see the PICT documentation

Installation

• run npm install pwtg

Usage

Generate tests into json file

import PictGenerator from "pwtg";

const generator = new Generator(
  "path/to/input-model-file.txt",
  "path/to/pict-binary",
);

await generator.generate("json", true, "path/to/output-json-file.json");

Generate tests into txt file

import PictGenerator from "pwtg";

const generator = new Generator(
  "path/to/input-model-file.txt",
  "path/to/pict-binary",
);

await generator.generate("text", true, "path/to/output-text-file.txt");

Just generate output string but do not save

import PictGenerator from "pwtg";

const generator = new Generator(
  "path/to/input-model-file.txt",
  "path/to/pict-binary",
);

await generator.generate("text", false);

console.log(generator.generated);

Generate output using seed file

What is seeding and when to use it - see HERE

import PictGenerator from "pwtg";

const generator = new Generator(
  "path/to/input-model-file.txt",
  "path/to/pict/binary",
);

await generator.generate(
  "text",
  true,
  "file/path/to/output-text-file.txt",
  "path/to/seed-text-file.txt",
);
