BankApp: Code Challenge: Authorizer The objective of this project was to create an application that authorizes a transaction for a specific account following a set of business rules. In order to complete the challenges some assumptions were made:

Sample usage of the Authorizer How the program should work? Your program is going to receive json lines as input in the stdin and should provide a json line output for each of the inputs, imagine this as a stream of events arriving at the authorizer. How the program should be executed? Given a file called operations that contains many lines describing operations in json format

$ git clone: https://github.com

The code will be in src/main package.

Console Input: Allows Gson parse the stdin JSON into the proper Object. Main Class: Manages the main run of the project Rules folder: manages the business rules using factory pattern Service folder: service class Account: Manages the Account Object logic Transaction: Manages the Transaction Object Logic. Run it To run the project you can do two things:

Run a JAR file: To do this navigate, in the command line to the main folder of the project and run the following command:

cd out/artifacts $ java -jar BankAppTest.jar Run it from Intellij IDEA Open the project in Intellij IDEA. Then go to src/main and right-click over MainRun.java and Run As -> Application in Run/Debug Configuration.

Once is running in the command line the project will wait for every line and process it.

Prerequisites Java 11

Test it There are 5 available. This files are available in src/test.

In the src/test package are 2 files. One for Account testing and one for Transaction testing. The 5 available test are build in order to follow the business rules.

Built With Java Gson - Gson is a Java library that can be used to convert Java Objects into their JSON representation.
