Runs a function against given inputs and tests the result against baseline outputs
Let's say you're writing a function that transforms some text into some other text. This package makes testing such a function easy, by letting you set up source files alongside their corresponding desired baseline output files, and then seeing if your function generates the right results.
Let's say you're writing a Markdown-to-HTML converter, and have set up your project like so:
lib/
md2html.js
test/
cases/
bold.md
bold.html
paragraphs.md
paragraphs.html
⋮
Here we assume lib/md2html.js
has a default export that is a function converting strings of Markdown to strings of HTML, synchronously.
To run the tests using baseline-tester, you can either use the CLI:
$ baseline-tester lib/md2html.js --cases test/cases --input md --output html
or you can do so programmatically (say, from test/runner.js
):
"use strict";
var path = require("path");
var baselineTester = require("baseline-tester");
var md2html = require("../lib/md2html.js");
baselineTester(md2html, {
casesDirectory: path.resolve(__dirname, "cases"),
inputExtension: "md",
outputExtension: "html"
});
It's common to want to ignore leading or trailing whitespace when comparing against the baseline files. baseline-tester will do this by default, but you can turn it off by specifying --trim=none
on the command line or trim: "none"
programmatically.
