Implement infrastructure for running unit tests

[rafgpereira]

🔖 Feature description

The implementation of an infrastructure for running unit tests in the Postiz project. This includes setting up a Continuous Integration (CI) environment and structuring the code to combine and automatically execute all tests.

🎤 Why is this feature needed ?

The implementation of a testing infrastructure is crucial to enable the development and execution of tests in the Postiz project. This feature is necessary because:

• Currently, it's not possible to accept test contributions due to lack of infrastructure
• It allows the team and contributors to develop and run unit tests consistently
• It enables automatic test execution on each pull request, ensuring code quality
• Ensures code quality and reliability
• Facilitates early bug detection
• Allows the community to contribute tests
• Improves long-term project maintainability

Moreover, this infrastructure will allow the acceptance of test contributions, such as the recently submitted PR for the PermissionsService, encouraging more community collaborations and improving the overall robustness of the project.

✌️ How do you aim to achieve this?

• Set up a Continuous Integration (CI) system, such as GitHub Actions or Travis CI
• Create automation scripts to run tests on each pull request
• Establish a standard directory structure for unit tests
• Configure Jest (or another testing tool) to recognize and automatically run all tests
• Document the process of creating and running tests for future contributors
