nodeunit-dataprovider

A quick solution for generating sets of repeating tests using an array of input data.

Node.js

To install:

npm install nodeunit-dataprovider

To use:

var dataprovider = require('nodeunit-dataprovider');

Example:

var dataprovider = require('nodeunit-dataprovider');
 
exports['doubled result'] = dataprovider(
    [
        {input: 4,  output: 8},
        {input: 8,  output: 16},
        {input: 16, output: 32}
    ],
    
    function (test, data) {
        test.strictEqual(data.input * 2, data.output);
        test.done();
    }
);
 
 
exports['doubled result with named doubles'] = dataprovider(
    {
        Set1: {input: 4, output: 8},
        Set2: {input: 8, output: 16},
        Set3: {input: 16, output: 32}
    },
 
    function (test, data, index) {
        test.strictEqual(data.input * 2, data.output);
        test.done();
    }
);

$ nodeunit test.js

test.js
✔ doubled result - #0: {"input":4,"output": ...
✔ doubled result - #1: {"input":8,"output": ...
✔ doubled result - #2: {"input":16,"output" ...
✔ doubled result with named doubles - #0: Set1
✔ doubled result with named doubles - #1: Set2
✔ doubled result with named doubles - #2: Set3
