Overview

This is an interview question from BNP Paris.

BowlingGame

Required to implement a bowling game. More info on the rules at: how to score for bowling

How to run

We use JUnit for testing. There are several ways (maven, gradle, ant, etc.) to compile and run the tests. Here, I show you how to use command line to run the tests.

1. Downloads

We need JUnit-5.4.0 to build and JUnit-platform-console-standalone-1.4.0 to print test execution results to the console.

2. Compile

Create out folder to store our compiled java files

mkdir out

We use JUnit-5.4.0 to build

javac -cp junit-jupiter-api-5.4.0.jar BowlingGame.java BowlingGameTest.java -nowarn -d out

3. Run TestCases

java -jar junit-platform-console-standalone-1.4.0.jar --class-path out --scan-class-path
