Unique Filename Generator Service

A service that generates unique temporary filenames for various application modules, each with specific naming requirements.

Capabilities

Generate filenames with custom patterns

• When generating a filename with prefix 'logs-' and postfix '.txt', returns a unique path ending with '.txt' and starting with the configured prefix @test
• When generating a filename with template '/tmp/myapp-XXXXXX', returns a path matching the template pattern with XXXXXX replaced by random characters @test

Generate filenames for multiple modules

• When generating filenames for a 'cache' module (prefix 'cache-', postfix '.dat') and a 'session' module (prefix 'session-', postfix '.json'), each generated filename has its respective prefix and postfix @test

Validate generated filenames

• Generated filenames are strings and contain a path separator character @test
