[TASK] Implement Automated Testing in CI/CD Pipeline

[ElioNeto]

🎯 Task Overview

Set up automated testing in GitHub Actions to run cargo test --all-features on every pull request and push to main branches.

📝 Description

Currently, tests need to be run manually. We need automated CI/CD to:

• Catch regressions early
• Ensure code quality before merging
• Validate all features work together
• Run on multiple Rust versions

🛠️ Implementation Plan

1. Create GitHub Actions Workflow

File: .github/workflows/test.yml

name: Tests

on:
  push:
    branches: [ main, develop ]
  pull_request:
    branches: [ main, develop ]

env:
  CARGO_TERM_COLOR: always

jobs:
  test:
    name: Test Suite
    runs-on: ubuntu-latest
    strategy:
      matrix:
        rust: [stable, beta, nightly]
    steps:
      - uses: actions/checkout@v4
      
      - name: Install Rust
        uses: dtolnay/rust-toolchain@master
        with:
          toolchain: ${{ matrix.rust }}
      
      - name: Cache cargo registry
        uses: actions/cache@v4
        with:
          path: ~/.cargo/registry
          key: ${{ runner.os }}-cargo-registry-${{ hashFiles('**/Cargo.lock') }}
      
      - name: Cache cargo index
        uses: actions/cache@v4
        with:
          path: ~/.cargo/git
          key: ${{ runner.os }}-cargo-git-${{ hashFiles('**/Cargo.lock') }}
      
      - name: Cache target directory
        uses: actions/cache@v4
        with:
          path: target
          key: ${{ runner.os }}-target-${{ matrix.rust }}-${{ hashFiles('**/Cargo.lock') }}
      
      - name: Run tests (all features)
        run: cargo test --all-features --verbose
      
      - name: Run doctests
        run: cargo test --doc --all-features

  fmt:
    name: Rustfmt
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: dtolnay/rust-toolchain@stable
        with:
          components: rustfmt
      - run: cargo fmt --all -- --check

  clippy:
    name: Clippy
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: dtolnay/rust-toolchain@stable
        with:
          components: clippy
      - run: cargo clippy --all-features -- -D warnings

2. Add Status Badges to README

[![Tests](https://github.com/ElioNeto/ApexStore/workflows/Tests/badge.svg)](https://github.com/ElioNeto/ApexStore/actions)
[![Clippy](https://github.com/ElioNeto/ApexStore/workflows/Clippy/badge.svg)](https://github.com/ElioNeto/ApexStore/actions)

3. Branch Protection Rules

Enable on main and develop branches:

• Require PR reviews before merging
• Require status checks to pass (Tests, Clippy)
• Require branches to be up to date

✅ Acceptance Criteria

• GitHub Actions workflow created
• Tests run on push to main/develop
• Tests run on all PRs
• Multiple Rust versions tested (stable, beta, nightly)
• Clippy checks enabled
• Rustfmt checks enabled
• Status badges in README
• Branch protection enabled

📊 Expected Benefits

• Automated regression detection
• Consistent code formatting
• Early warning of breaking changes
• Confidence in PR merges
• Professional project presentation
