Sinon.js, a popular JavaScript testing library for spies, stubs, and mocks, has released version 19.0.3, succeeding the previous stable version 19.0.2. While both versions share the same core functionality and licensing under BSD-3-Clause, several noteworthy changes enhance the developer experience. The primary difference lies in dependency updates, specifically within the dependencies section. Version 19.0.3 upgrades @sinonjs/fake-timers from version 13.0.2 to 13.0.5. This likely includes bug fixes and improvements within the fake timers functionality, crucial for controlling time-dependent behavior in tests.
Beyond this, there are no direct, noticeable differences in the other dependencies. However, developers should note the release date, with version 19.0.3 pushed on March 19th, 2025, whereas version 19.0.2 was released on September 13th, 2024 meaning that the latest version contains all the improvements and fixes that were incorporated on the last 7 months.
For developers already using Sinon.js, upgrading to 19.0.3 is generally recommended, assuming compatibility with existing projects. The updated @sinonjs/fake-timers package enhances reliability, mainly for time management. New users benefit from starting with the newest version, taking advantage of these improvements without encountering older bugs or incompatibilities. The library remains committed to its core mission of simplifying JavaScript testing through helpful utilities. As always, thorough testing is advised when upgrading any dependency.
