Integration & QA Testing of Koree Apps & API

Context

Koree is an innovative cashback application developed for Francophone Africa, offering a simple, secure, 100% digital, and convenient solution to enjoy the best deals while shopping. The idea of Koree was born in 2018 to solve the problem of change in stores and digitize small change.

Since February 10, 2023, I have contributed as a Freelance QA Tester to improving the quality and maintainability of the Koree API by performing E2E, unit, and integration tests. I have also participated in the development of the mobile application in Flutter and the API in Laravel.

  • E2E Testing with Cypress to ensure comprehensive test coverage of critical features of the Koree & Koree Pro applications.
  • Backend Testing with Postman to verify the integrity and performance of the Koree API.
  • Unit and Integration Testing to ensure code quality and maintainability.
  • Mobile Development with Flutter, integrating new features and fixing encountered issues.
  • Backend Development with Laravel to enhance API features and ensure its quality and maintainability.
  • Code Versioning via Git and GitHub, enabling effective collaborative work and smooth project version management.

Challenges and Solutions

  • Quality Assurance: Implementing automated tests to detect regressions and ensure the stability of new features.
  • Continuous Improvement: Collaborating with developers to enhance API features and optimize the code.
