Fundamental mochajs

1. MochaJS
Mocha is a feature-rich JavaScript test
framework running on Node.js and in the
browser, making asynchronous testing
simple and fun

2. Testing basics

3. Testing Scale
Unit
A single piece of code
(usually an object or a
function) is tested,
isolated from other
pieces
Acceptance
Automatic testing of the
entire application, for
example using a tool
like Selenium to
automatically run a
browser.
Integration
Multiple pieces are
tested together, for
example testing
database access code
against a test database

4. Testing strategies
Unit Test
- Functional Tests
- Test are written
after the
implementation of
methods/functions
TTD/BBD
- Behavioral Test
- Tests are written
before the
implementation of
methods/functions

17. Presentation design
This presentation uses the following typographies and colors:
◇ Titles: Nixie One
◇ Body copy: Muli
You can download the fonts on this page:
http://www.google.com/fonts#UsePlace:use/Collection:Nixie+One|Muli:300,400,300italic,400italic
Click on the “arrow button” that appears on the top right
Aquamarina #00e1c6 / Turquoise #19bbd5 / Skyblue #2c9dde /
Light gray #c6daec / Dark blue #0e293c
You don’t need to keep this slide in your presentation. It’s only here to serve you as a design guide if
you need to create new slides or download the fonts to edit the presentation in PowerPoint®

18. SlidesCarnival icons are editable shapes.
This means that you can:
● Resize them without losing quality.
● Change fill color and opacity.
● Change line color, width and style.
Isn’t that nice? :)
Examples:

19. Now you can use any emoji as an icon!
And of course it resizes without losing quality and you can change
the color.
