 # A JavaScript Testing Framework

 Jasmine is a Behavior Driven Development testing framework for JavaScript. It does not rely on browsers, DOM, or any JavaScript framework. Thus it's suited for websites, [Node.js](http://nodejs.org) projects, or anywhere that JavaScript can run.

 at the time of release. Other browsers, as well as older & newer versions of some supported browsers, are likely to work.

+# Jasmine Core 5.0.0-alpha.0 Release Notes
+
+## Summary
+
+This release primarily adds support for parallel execution via the `jasmine`
+package. Please see its release notes and the 
+[parallel documentation](https://jasmine.github.io/tutorials/running_specs_in_parallel)
+for more information. Additionally, this release cleans up a few outdated
+interfaces.
+
+This is a pre-release for a major version. It contains breaking changes, and
+there may be further breaking changes between this release and the final 5.0.0
+release.
+
+## Breaking changes
+
+* Use addEventListener in browsers rather than setting window.onerror
+
+  This simplifies error handling in browsers, makes Jasmine's own integration
+  tests easier to debug, and provides stack traces for more unhandled
+  exceptions. However, some browsers will provide less error information when
+  the error comes from a file:// URL. Additionally, Jasmine will no longer
+  override existing onerror handlers, and setting window.onerror will no longer
+  override Jasmine's global error handling. (Use `jasmine.spyOnGlobalErrors`
+  instead.)
+
+* Made Env#execute async
+* Env#execute no longer takes a callback
+* The `boot` function exported by the core module returns the same object
+  every time it's called.
+* Removed node_boot.js. Use the exported `boot` function instead.
+
+### Changes to supported environments
+
+The following previously supported environments are no longer supported:
+
+* Node <16.14
+* Safari 14
+* Firefox 91
+
+Although this release may still work in some of those environments, we no
+longer test against them and won't try to maintain compatibility with them in
+future releases.
+
+## New features
+
+* Support for parallel execution in Node.js using the `jasmine` package
+
+## Bug fixes
+
+* The global error handler is uninstalled at the end of env execution.
+
+## Supported environments
+
+jasmine-core 5.0.0-alpha.0 has been tested in the following environments.
+
+| Environment       | Supported versions |
+|-------------------|--------------------|
+| Node              | 16.14+,         18 |

+  an error rather than behaving unpredictably.

+
+## New features
+
+* Support for parallel execution in Node via the `jasmine` package
+  See the [parallel guide](https://jasmine.github.io/tutorials/running_specs_in_parallel)

+# Jasmine Core 5.0.1 Release Notes
+
+## Changes
+
+* Optionally restore the pre-5.0 behavior of boot() always creating a new instance
+
+  This is needed by jasmine-npm (and likely other tools like it) that may
+  need to create and use multiple envs in sequence.

+# Jasmine Core 5.1.0 Release Notes
+
+## Changes
+
+* Exclude inherited Error properties from stack trace
+
+* Fixed error when formatting Error object with non-Error cause property
+
+  Merges [#2013](https://github.com/jasmine/jasmine/pull/2013) from @angrycat9000.
+
+  Fixes [#2011](https://github.com/jasmine/jasmine/issues/2011).
+  
+* Added `throwUnless` and `throwUnlessAsync`
+
+  These are similar to `expect` and `expectAsync` except that they throw
+  exceptions rather than recording matcher failures as spec/suite failures.
+  They're intended to support using Jasmine matchers in [testing-library's](https://testing-library.com/)
+  `waitFor`, and also provide a way to integration-test custom matchers.
+
+  Fixes [#2003](https://github.com/jasmine/jasmine/issues/2003).
+
+  Fixes [#1980](https://github.com/jasmine/jasmine/issues/1980).

Moreover, Pivotal hasn't actually been the sole copyright owner since the first external contribution was merged.

Steve Gravrock	e56bd3918b	Added `throwUnless` and `throwUnlessAsync` These are similar to `expect` and `expectAsync` except that they throw exceptions rather than recording matcher failures as spec/suite failures. They're intended to support using Jasmine matchers in testing-library's `waitFor`, and also provide a way to integration-test custom matchers. These funtions are not equivalent to `expect` and `expectAsync` and should not be used in situations where you want a matcher failure to reliably fail the spec. Whether that happens depends on the structure of the surrounding code. In general, you should only use `throwUnless` when you expect something (which could be your own code or library code like `waitFor`) to catch the resulting exception. Fixes #2003. Fixes #1980.	2023-07-15 12:08:11 -07:00

I'm not willing to accept that kind of churn just becuse the Prettier devs changed their mind about what color the bikeshed should be.

Steve Gravrock	390cc45af2	Dropped support for Node 16 Node 16 will reach EOL no later than a few months after Jasmine 5 is released. Experience with Node 12 and Node 14 has shown that our dependencies, especially dev dependencies, move on from past-EOL Node versions fairly quickly. That can make it difficult to continue supporting them. Since long term support for past EOL Node versions is a non-goal and many users expect that Node versions will only be dropped in major releases, it's better to drop it in 5.0.	2023-04-27 19:32:18 -07:00

Steve Gravrock	e14d9c4be3	Parallel: forbid beforeAll/afterAll at the top level Either running these once total or running them once per process would be the wrong choice for a significant chunk of users, so do neither.
