php-test

A PHPUnit exercise

The Challenge

According to the test, what string should be returned by the Motto class?

Explanation

The aim of this exercise is simply to explore a typical PHP testing setup with an optional bit of Docker thrown in. There are no trick questions! At interview, we will discuss how you went about the solution.

Set up

You'll need either a recent version of Docker installed on your machine (tested on PC and Mac) or PHPUnit (recommended version 9) and PHP (recommended version 7.4) available on your command line/prompt/shell.

1. Clone the code from Github: git clone https://github.com/SheffieldUni/php-test.git
2. Change directory to the code folder: cd php-test
3. Run phpunit in Docker: docker compose run phpunit phpunit
4. OR Run with your locally installed PHP/PHPUnit: phpunit

If you're using Docker, it will first download the PHPUnit Docker image, then run the command.

When the command has finished, you'll see some test output which indicates that a class method is returning an incorrect string. What should that text be and where would you change it?
