Sinon 3.0.0 represents an incremental update to the popular JavaScript testing library, building upon the foundation laid by version 2.4.1. Both versions share the core functionality of providing spies, stubs, and mocks for robust unit testing. A key difference lies in the updated dependencies: Sinon 3.0.0 introduces nise and updates lolex to 2.1.2, potentially bringing improved fake server/XHR capabilities and clock manipulation features, respectively. This can offer developers more precise control over testing asynchronous code and network interactions. In contrast, version 2.4.1 relies on an older version of lolex (1.6.0) and lacks the nise dependency.
The developer experience is further enhanced in 3.0.0 with the inclusion of proxyquire and npm-run-all in its set of tools. proxyquire-universal is also present, whereas 2.4.1 does not make use of these tools. While the core testing methodologies remain consistent between versions, upgrading to 3.0.0 may provide access to these streamlined testing utilities that improve the development workflow. Also note, though both versions use a similar tech stack for development and testing, including Mocha, ESLint, and Browserify, these additional utilities could bring performance or reliability improvements.
Both versions are licensed under the BSD-3-Clause license and are available on npm. Developers considering an upgrade from 2.4.1 to 3.0.0 should evaluate the new dependencies and tooling. The updated lolex version and the addition of nise, proxyquire, npm-run-all and proxyquire-universal could introduce breaking changes in specific testing scenarios while bringing additional improvements to the overall stability of tests when upgrading.
