In the past 9 years, I’m using PHPUnit on a regular base. In this session, I’ll start with the basics and guide you through 4 parts of writing tests using PHPUnit.
- Part 1: Unit Testing
- Part 2: Integration Testing
- Part 3: Acceptance Testing
- Part 4: Smoke Testing
After this session, you'll have a good understanding of all 4 types of tests, how they should be structured and in which cases they are used. On top, you'll get a lot of examples and exercises for each type so you can stay curious and keep learning after the conference.

## What you will learn from this talk
- How to conceptually separate between the 4 types.
- When to Mock which part of the code.
- What SmokeTests are and how to set them up using PHPUnit.

## Why should you accept this talk
This is a new talk I've prepared for 2019's ConFoo. Background for this talk is to provide an overview of how to structure and write these 4 kinds of tests and where and when to separate between them. The slides will show a lot of graphical and source code explanations for each of the part.
