func WebpackJsdomTapePlugin({ string: url, string: entry, bool: exit = true, bool: errorsOnly = false})

creates a test runner for when the given entry, at the given url.

when the test is done, process exits with 0 if passed, and 1 if any errors occured. exit option allow you to change this behavior of this plugin. Note that using exit: false might introduce a memory leak since jsdom might not clean everything properly.

errorsOnly option allow to only show tests on error allowing clean ouput.

test example

// tape is included as a global
tape("test name", (test) => {
  test.equal(1, 1, "ok")
  test.end()
})

integration example

You will need a webpack entry that require all tests files and an html file that will include this entry

src/tests.js

// where you might need to use webpack file-loader for the following html file
import "./tests.html"

// you may need to include your polyfill here
// eg: import "babel/polyfills"

var context = require.context(
  // place where your modules are
  "../web_modules",
  true,
  // you pattern to glob the test files
  /__tests__\/.*\.js$/
)

context.keys().forEach(context)

src/tests.html

<!doctype html>
<meta charset="utf-8">
<meta http-equiv="x-ua-compatible" content="ie=edge">
<title>Tests</title>
<h1>TAP</h1>
<pre id="test-Pre"></pre>
<script>
  var log = console.log
  var target = document.getElementById("test-Pre")
  window.console.log = function(message) {
    target.appendChild(document.createTextNode(message + "\n"))
    log.apply(console, arguments)
  }
</script>
<script src="./tests.js"></script>
