Test Build Result Utility

The `test-build-result` package provides a utility for comparing the output of a build process against a set of expected files or directories. This is crucial for integration testing, ensuring that build tools, compilers, or bundlers produce consistent and correct artifacts over time. It offers features for specifying actual and expected file paths, handling file content comparisons, and reporting discrepancies. As of version 1.1.2, the package has been updated with features like `testExists` to verify the presence of specific files and the ability to automatically generate expected directories if they do not exist, streamlining the setup for initial tests. The package maintains an active release cadence, with several minor updates recently, indicating ongoing maintenance and responsiveness to user needs. Its primary differentiator lies in its focused approach to asserting the correctness of filesystem-based build outputs, contrasting with more general-purpose assertion libraries.
