Testing Database Backup and Restore Operations in LiteMall

This test suite evaluates database utility functions for the LiteMall application, focusing on backup and restore operations. The tests verify database backup creation and data restoration functionality while handling database credentials and file operations.

Test Coverage Overview

The test suite covers core database management operations with a focus on backup and restore functionality.

Key areas tested include:

Database backup creation to SQL file
Database restoration from SQL file
Credential handling and validation
File system operations for SQL dumps

Implementation Analysis

The testing approach uses JUnit for unit testing database utilities, implementing direct file system interactions and database operations. The tests validate both backup creation and data restoration while properly managing database connections and file handles.

Notable patterns include:

Direct file system access for SQL dumps
Database credential management
Safe database restoration practices

Technical Details

Testing tools and configuration:

JUnit 4 testing framework
DbUtil custom utility class
File system operations for SQL handling
MySQL database connection management
Configurable database credentials

Best Practices Demonstrated

The test suite demonstrates solid testing practices for database operations, including proper resource handling and safety considerations. Notable practices include:

Commented safety warnings for destructive tests
Separation of backup and restore operations
Proper file handling
Clear test method naming
