Remember, you can run the tests using
mocha.run() in the browser if you'd like — then read the results, refresh the page, and keep going afterwards.
Note: If you're using the Learn IDE, this is how to use mocha.run():
- Type "httpserver" into your learn IDE console.
- Type the ip it gives you into your browser. (The ip will look something like this: 188.8.131.526:30615)
- Go to your browser's console and type mocha.run() and press
- Any errors from your code will now appear in your browser on the tab in which you typed your ip in step 2.
- Debug, editing your work in index.js, saving it, and repeating steps 3-5 until all tests pass.
