Testcase Generator

Generate testcases by simple but highly customizable rules.


Usage

$3

``bash
npm i testcase-gen
`

$3

For example: sum of two numbers.

`javascript
const { Generator } = require("testcase-gen");

const rules = [
{
name: "2 Positives (1 ~ 99999)",
regex: /[1-9]\d{0,4} [1-9]\d{0,4}/,
repeat: 20,
},
{
name: "2 Negatives (-1 ~ -99999)",
regex: /-[1-9]\d{0,4} -[1-9]\d{0,4}/,
repeat: 20,
},
{
name: "1 Zero, 1 Positive (1 ~ 100000)",
generator: () => 0 ${1 + Math.floor(Math.random() * 100000)},
repeat: 10,
},
{
name: "1 Zero, 1 Negative (-1 ~ -100000)",
generator: function () {
return 0 -${1 + Math.floor(Math.random() * 100000)};
},
repeat: 10,
},
{
name: "2 Zero",
text: "0 0",
},
];

const generator = new Generator(rules);
console.log(generator.gen());
`

Rules

Each rule must have one of the following properties: generator or regex or text.

And the following properties are optional: name, repeat.

$3

There are 3 ways to generate testcases: Generator Function, Regex and Text.

The order of rule applying is:

1. Generator Function
2. Regex
3. Text

> I recommand you to use Generator Function because it is more flexible.
