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}
