This library provide Tag functions for Parameterized testing with Markdown-like table.
This is inspired by jest-each.
Install with npm:
npm install parameterized-table-template import * as assert from "assert"; import { parameterizedTableTag } from "parameterized-table-template"; describe("example", () => { describe("sum tests", () => { // function for testing const sum = (x, y) => x + y; // generate tests parameterizedTableTag` first | second | expected ${1} | ${2} | ${3} ${2} | ${1} | ${3} ${2} | ${2} | ${4} `.forEach(({ first, second, expected }) => { it(`${first} + ${second} = ${expected}`, () => { assert.strictEqual(sum(first, second), expected); }); }); }); });Notes: For TypeScript User
// parameterizedTableTag allow to pass generics type parameterizedTableTag<{ first: number, second: number, expected: number }>` first | second | expected ${1} | ${2} | ${3} ${2} | ${1} | ${3} ${2} | ${2} | ${4} `.forEach(({ first, second, expected }) => { it(`${first} + ${second} = ${expected}`, () => { assert.strictEqual(sum(first, second), expected); }); });parameterizedTableTag is a Tag functions.
It return array of object that is defined in table.
parameterizedTableTag takes a tagged template string with:
- First row of variable name column headings separated with
| - One or more subsequent rows of data supplied as template literal expressions using
${value}syntax.
const table = parameterizedTableTag` first | second | expected ${1} | ${2} | ${3} ${2} | ${1} | ${3} ${2} | ${2} | ${4} `; /* [ { "expected": 3, "first": 1, "second": 2 }, { "expected": 3, "first": 2, "second": 1 }, { "expected": 4, "first": 2, "second": 2 } ] */See Releases page.
