Jasmine Core 5.10.0 Release Notes

New Features

• Optionally detect promise rejections that are handled after an initial unhandled promise rejection event and don't report them as errors. This is off by default because it comes with a performance cost. It can be enabled by setting the detectLateRejectionHandling config property to true.

• Add getSpecProperty to retrieve data that was set with setSpecProperty.

  • Merges #2072 from @bonkevin

• Show spec duration in the HTML reporter.

  • Merges #2073 from @bonkevin

• Protect GlobalErrors against monkey patching.

  All currently shipped versions of zone.js contain a monkey patch that fails to pass constructor arguments on to GlobalErrors. This patch normally has no effect because zone.js is normally installed after GlobalErrors is instantiated, but it would crash Jasmine if it was applied early enough.

Deprecations

• Issue a deprecation warning if the suite/spec order passed as a parameter to Env#execute causes a suite to be re-entered.

Changes to supported environments

• Added Firefox 140 (current ESR) to supported environments
• Demoted Firefox 128 (previous ESR) to best-effort support

Internal improvements

• Core suite/spec execution flow has been significantly simplified.
