Enforce Unit Tests on Every Pull Request

[Ashinch]

Description

To maintain code quality and ensure that new features and bug fixes do not introduce regressions, we need to enforce unit tests for every pull request. Each pull request should include sufficient unit tests covering new and modified code.

Task

1. Configure the repository to run unit tests automatically for every PR.
2. Ensure that the PR cannot be merged until all tests pass.

Steps to Implement

1. Create a GitHub Actions workflow that runs on every pull request.
2. The workflow should include a step to run the ./gradlew test command.
3. Set up the workflow to block merging if the tests fail.

Additional Information

• Refer to the GitHub Actions documentation for setting up workflows.
• Make sure to test the workflow with a sample PR to ensure it works as expected.

Good First Issue

This is a great issue for new contributors to get familiar with GitHub Actions and Gradle.
