Flight Search

Problem

Your goal is to implement a simple flight search.

Given

• airport of origin
• airport of destination
• date of departure
• number of adult, child and infant passengers

When you perform the search

Then you get the list of:

• flight code matching the route
• total flight price (for all passengers)

Implementation considerations

We ask you to solve it using the Java programming language. You are only allowed to use test libraries (JUnit, TestNG, Hamcrest,...) and nothing else.

You are free to implement any mechanism for feeding input into your solution (for example, using hard coded data within a unit test).

Remember that the automated and self-checking tests are mandatory. You should provide sufficient evidence that your solution is complete by, as a minimum, indicating that it works correctly against the supplied test data.

We kindly ask you to put your code on a public project in github.com under your account. Use Maven or Gradle as automation tool and link it to a build service likeTravis CI.

What we value most?

The goal is to provide us with a full understanding of your coding style and skills. We’ll pay particular attention to:

• readable and well-structured code
• design and domain modelling
• quality of tests

Business rules and constraints

• Search only for direct flights (no stopovers)
• Assume there is always seat availability
• All flights leave every day
• There is only one currency (€)

Pricing rules
