This pull request adds a comprehensive set of new unit tests across several core modules, focusing on improving coverage for collections, conversion, file I/O, and JSON handling. The new tests verify immutability, edge cases, error handling, and correct fallback behaviors, as well as introduce a new test class for the
StringToIterableConverter. These changes help ensure the robustness and reliability of the library's core utilities.Collections:
ofList,ofSet, andofMapmethods inListsTest,SetsTest, andMapsTest, ensuring that attempts to modify returned collections throwUnsupportedOperationException. [1] [2] [3]AbstractDequeTest, includingremoveFirstOccurrence, offer/poll sequences, and push/pop operations.Conversion:
StringToIterableConverterTestthat covers acceptance, conversion, fallback, and priority logic forStringToIterableConverterandStringToCollectionConverter.AbstractConverterTestwith tests forhashCode,resolvePriority, and additional equality scenarios.File I/O and Filtering:
StandardFileWatchServiceto cover starting, stopping, closing, and handling multiple listeners.FileExtensionFilterTestwith cases for dot-prefixed extensions and filename filter acceptance.JSON Handling:
JSONArrayTestandJSONObjectTestfor invalid double values, fallback behaviors foroptBoolean,optDouble,optInt,optLong, andoptString, as well as write operations and exception handling. [1] [2]Classloading:
AbstractURLClassPathHandleTestwith a test for setting and restoring priority.
