acquit-require

Utility to pull mocha tests into markdown, HTML, etc.This is the function you want to use. Given a string (markdown, HTML, Jade, etc.) and the raw source code of some mocha tests, this function returns a string with [require:bar] replaced with the source code of the first test that matches the regexp 'bar'.
Given the below markdown article:

Printing "Hello, World" in JavaScript is easy:

```
[require:bar]
```

This is how you print "Bye!" instead:

```
[require:baz]
```

And the below mocha test code:

describe('foo', function() {
  it('bar', function() {
    console.log('Hello, World!');
  });

  it('baz', function() {
    console.log('Bye!');
  });
});

The transform() function will pull the source code of the two tests into your markdown file.

const output = transform(article, code);

const logStatements = output.match(/console\.log(.*);/g);

assert.ok(logStatements);
assert.equal(logStatements[0].trim(), `console.log('Hello, World!');`);
assert.equal(logStatements[1].trim(), `console.log('Bye!');`);

assert.equal(findTest('foo', code).trim(),
  `console.log('Hello, World!');`);
assert.equal(findTest('bar', code).trim(),
  `console.log('Hello, World!');`);
assert.equal(findTest('foo bar', code).trim(),
  `console.log('Hello, World!');`);
assert.equal(findTest('baz', code).trim(),
  `console.log('Bye!');`);
assert.ok(!findTest('bar baz', code));
