Unreal Math Operator

Description

I am a huge of the magic created everyday by mathematical dilemmas and aspects. In fact I was so stoned with the idea of the Fibonnaci sequence and its manifesataion in all the universe

So for the Software testing and the devops lab, i decided to create a nest application that performs some of the most stunning mathematical operations in order to test this application and try to deploy it

Technologies

• Nestjs : development technology
• mysql : database
• Jest : for unit and end to end testing
• Docker: for the containerization of the application
• Git / Github : for version control and definition of the pipeline
• AWS : as the host cloud provider

CI / CD pipeline

The pipeline for this repository is composed of two jobs:

• Testing: this job pulls the source code from github into a ubuntu machine , install deps and run the needed runs the created tests (unit and e2e tests)
• Deployment: this job does the following:
  • connects to an EC2 instance
  • stops the containers if they are working
  • removes the old version of the code
  • clone the newer version of the code
  • creates .env file with the needed env
  • creates the containers needed with docker compose

DISCLAIMER

The deployment failed due to issues with connecting to the ec2 instance (time out / change in the hostname of the instance from aws ...)

The application is missing a lot of features and it is open for improvement. Who knows maybe i ll finish developping the rest of the desired features in the future

Note for Mr Wassim

• The main application is in the folder backed there you can find a readme file that will explain the testing code i implemented and the location of each test script is provided inn more details under the src directory there
