In this hands-on activity, we'll try to implement a feature and fix a bug with Test-Driven Development (TDD) approach.
First, you'll need to be able to access this project in your local Xcode.
-
Clone this project to your local directory. You can use GitHub's
Open in Xcodefeature. Note: Clone the main branch first. You can clone the finished project after this event if you want
-
Tap
Openwhen your browser is asking for permission.
-
You can save it anywhere you want and name it anything.
-
Then when Xcode shows a warning, tap
Trust and Open. This warning is always shown when you open an Xcode project online.
In this hands-on project, we will have two tasks that we should complete using Test-Driven Development approach:
The first task is for you to implement a scoring feature in the Quiz App. Here are the acceptance criteria:
Given: Player is not playing a game
When: Player starts a game
Then: Player initial score, combo bonus, and combo multiplier set to 0
Given: Player is playing a game
When: Player selects a correct answer
Then: Player score increases by 10
Given: Player is playing a game
When: Player selects correct answer
Then: Player combo bonus increases by 5 times combo multiplier
Given: Player selected correct answer
When: Player selects another correct answer
Then: Player combo multiplier increases by 1
Given: Player is playing a game
When: Player selects a wrong answer
Then: Player score decreases by 5
Given: Player selected correct answer
When: Player selects a wrong answer
Then: Player score increases by combo bonus
Given: Player selected correct answer
When: Player selects a wrong answer
Then: Player combo bonus and multiplier resets to 0
Given: Player is playing a game
When: Player ends the game
Then: Player score added by the current combo bonus
There is a bug inside the GameProgressView, where the progress bar does not move during the quiz. Try to fix it with the Test-Driven Development approach!
