Test runner for doctests using JSDoc examples and node-tap.

Based on the hard work of @yamadapc and this project.

• Examples
• Roadmap and known bugs
• Changes

npm i -D jsdoctap

jsdoctap some-file.js

I recommend adding it to your npm scripts. Example:

{
  "scripts": {
    "test": "jsdoctap src/*.js"
  }
}

jsdoctap has one option: -i (or --ignore) Example: jsdoctap -i src/*.test.js -i src/*.config.js src/*.js.

Tests must be under an @example in a valid JSDoc comment. The return value to be tested against must come after a line comment with an arrow (Clojure REPL style):

/**
 * Identity
 * @example
 * id(1) // => 1
 */

Line breaks between the call and the comment are fine:

/**
 * Identity
 * @example
 *   id(1)
 *   // => 1
 */

Line breaks in function calls currently do not work:

/**
 * This will break!
 * @example
 * id(
 *   1
 * ) // => 1
 */

Source and examples that need to be Babelified work just fine, as long as you have Babel configured and modules installed.

• Handle expecting errors
• Fix multi-line function calls
• Fix dependencies that need to be Babelified
• Add ability to have custom test case name
• Clean up comment-parser and getModuleName (in tap)
• More tests and examples
