Test Scenarios

Clean System Installation

  1. Fresh OS Installation

    • Minimal OS installation
    • No development tools pre-installed
    • Default package repositories only

  2. Container Testing

    • Docker containers with base OS images
    • Podman compatibility
    • Multi-stage builds

  3. CI/CD Environments

    • GitHub Actions
    • GitLab CI
    • Jenkins
    • Azure DevOps

Development Environment Testing

  1. Existing Development Environment

    • System with build tools already installed
    • Conflicting package versions
    • Custom library paths

  2. Minimal Development Environment

    • Basic compiler only
    • Missing optional dependencies
    • Limited disk space

Automated Testing Framework

Test Scripts Validation

1. Dependency Checker (check-deps.sh)

# Test all platforms
for platform in ubuntu debian arch fedora; do
    echo "Testing on $platform..."
    docker run --rm -v $(pwd):/mem $platform:latest /mem/scripts/check-deps.sh
done

# Test dependency auto-installation
./scripts/check-deps.sh --auto-install --dry-run

# Test missing dependencies
# (temporarily rename dependency to simulate missing)
mv /usr/bin/cmake /usr/bin/cmake.bak
./scripts/check-deps.sh
mv /usr/bin/cmake.bak /usr/bin/cmake

Expected Results:

  • ✅ Correct platform detection on all systems
  • ✅ Accurate dependency status reporting
  • ✅ Proper package installation commands for each platform
  • ✅ Graceful handling of missing dependencies

2. Installation Script (install.sh)

# Test installation modes
./scripts/install.sh --dry-run
./scripts/install.sh --skip-deps --dry-run
./scripts/install.sh --prefix=/tmp/test-install

# Test error handling
./scripts/install.sh --prefix=/invalid/path

# Test force installation
./scripts/install.sh --force --prefix=/tmp/test-install

Expected Results:

  • ✅ Successful build and installation on all platforms
  • ✅ Proper PREFIX handling
  • ✅ Correct dependency installation for each platform
  • ✅ Graceful error handling for invalid paths
  • ✅ Force reinstallation works correctly

3. Rapala Detection (detect-rapala.sh)

# Test detection
./scripts/detect-rapala.sh detect

# Test with no rapala
mv ~/.rapala ~/.rapala.bak 2>/dev/null || true
./scripts/detect-rapala.sh detect
mv ~/.rapala.bak ~/.rapala 2>/dev/null || true

# Test installation
./scripts/detect-rapala.sh install --dry-run

# Test verification
./scripts/detect-rapala.sh verify

Expected Results:

  • ✅ Accurate detection of rapala installations
  • ✅ Proper handling when no rapala found
  • ✅ Successful hook installation
  • ✅ Verification works correctly

4. Verification Script (verify-install.sh)

# Full verification
./scripts/verify-install.sh --verbose

# Test with missing components
rm /usr/local/bin/mem
./scripts/verify-install.sh

# Test auto-fix
./scripts/verify-install.sh --fix-issues

Expected Results:

  • ✅ Comprehensive system validation
  • ✅ Accurate problem detection
  • ✅ Useful troubleshooting information
  • ✅ Auto-fix functionality works

5. Template Application (apply-templates.sh)

# Test in clean directory
mkdir /tmp/test-project && cd /tmp/test-project
git init
/path/to/mem/templates/apply-templates.sh --dry-run

# Test overwrite protection
echo "existing" > .gitignore
/path/to/mem/templates/apply-templates.sh

# Test force overwrite
/path/to/mem/templates/apply-templates.sh --force

Expected Results:

  • ✅ Templates applied correctly
  • ✅ Existing files protected
  • ✅ Force mode works
  • ✅ Git repository detection works

6. Uninstallation Script (uninstall.sh)

# Test dry run
./scripts/uninstall.sh --dry-run

# Test selective removal
./scripts/uninstall.sh --keep-hooks

# Test complete removal
./scripts/uninstall.sh --remove-data --force

Expected Results:

  • ✅ Accurate removal detection
  • ✅ Selective removal options work
  • ✅ Complete removal works
  • ✅ No broken systems after uninstall

Cross-Platform Compatibility Tests

Container-Based Testing

# Ubuntu test
FROM ubuntu:22.04
RUN apt update && apt install -y git
COPY . /mem
WORKDIR /mem
RUN ./scripts/install.sh
RUN ./scripts/verify-install.sh

# Arch test
FROM archlinux:latest
RUN pacman -Sy --noconfirm git
COPY . /mem
WORKDIR /mem
RUN ./scripts/install.sh
RUN ./scripts/verify-install.sh

# Alpine test
FROM alpine:latest
RUN apk add --no-cache git bash
COPY . /mem
WORKDIR /mem
RUN ./scripts/install.sh
RUN ./scripts/verify-install.sh

Virtual Machine Testing

# Test script for VM environments
#!/bin/bash
set -e

# Create VM snapshots for each platform
for platform in ubuntu-22.04 debian-12 fedora-39; do
    echo "Testing on $platform..."

    # Restore clean snapshot
    vm restore $platform-clean
    vm start $platform

    # Copy mem source
    scp -r . vm-$platform:/tmp/mem

    # Run installation
    vm ssh $platform "cd /tmp/mem && ./scripts/install.sh"

    # Run verification
    vm ssh $platform "cd /tmp/mem && ./scripts/verify-install.sh"

    # Test functionality
    vm ssh $platform "mem init test && cd test && echo hello | mem hash-object --stdin --write"

    vm stop $platform
done

Performance Testing

Installation Performance

# Measure installation time
time ./scripts/install.sh
