Sinon.JS is a popular JavaScript library providing powerful tools for test spies, stubs, and mocks, enhancing the capabilities of unit testing. Examining versions 1.4.0 and 1.3.4 reveals key differences that highlight the library's evolution. Version 1.4.0 introduces a dependency on "buster-format" (~0.5), suggesting enhanced output formatting or reporting features which could improve the readability of test results. While both versions share the same core functionality as test spies/stubs/mocks, enabling the isolation of code units during testing, version 1.4.0 also includes several development dependencies like "buster-core" (~0.6), "buster-test" (~0.5), "http-server" (*), "buster-assertions" (~0.10), and "buster-evented-logger" (~0.4). These indicate improvements or upgrades to the testing infrastructure used during Sinon.JS's development. This means faster releases and more quality. The release date difference is also substantial with only ~3 months between the releases, making the jump to 1.4.0 substantial for developers who used older versions.
