-first loading of test files (@giltayar)Mocha is going ESM-first! This means that it will now use ESM
import(test_file)
to load the test files, instead of the CommonJSrequire(test_file)
. This is not a problem, asimport
can also load most files thatrequire
does. In the rare cases where this fails, it will fallback torequire(...)
. This ESM-first approach is the next step in Mocha's ESM migration, and allows ESM loaders to load and transform the test file.#4636: Remove deprecated

v8.2.0
Compare Source
The major feature added in v8.2.0 is addition of support for global fixtures.
While Mocha has always had the ability to run setup and teardown via a hook (e.g., a
before()
at the top level of a test file) when running tests in serial, Mocha v8.0.0 added support for parallel runs. Parallel runs are incompatible with this strategy; e.g., a top-levelbefore()
would only run for the file in which it was defined.With global fixtures, Mocha can now perform user-defined setup and teardown regardless of mode, and these fixtures are guaranteed to run once and only once. This holds for parallel mode, serial mode, and even "watch" mode (the teardown will run once you hit Ctrl-C, just before Mocha finally exits). Tasks such as starting and stopping servers are well-suited to global fixtures, but not sharing resources--global fixtures do not share context with your test files (but they do share context with each other).
Here's a short example of usage:
Fixtures are loaded with
--require
, e.g.,mocha --require fixtures.js
.For detailed information, please see the documentation and this handy-dandy flowchart to help understand the differences between hooks, root hook plugins, and global fixtures (and when you should use each).

🐛 Fixes
v8.1.0
Compare Source
In this release, Mocha now builds its browser bundle with Rollup and Babel, which will provide the project's codebase more flexibility and consistency.
While we've been diligent about backwards compatibility, it's possible consumers of the browser bundle will encounter differences (other than an increase in the bundle size). If you do encounter an issue with the build, please report it here.
This release does not drop support for IE11.

💥 Breaking Changes
#4164: Mocha v8.0.0 now requires Node.js v10.12.0 or newer. Mocha no longer supports the Node.js v8.x line ("Carbon"), which entered End-of-Life at the end of 2019 (@UlisesGascon)
#4175: Having been deprecated with a warning since v7.0.0,
mocha.opts
is no longer supported (@juergba)✨ WORKAROUND: Replace
mocha.opts
with a configuration file.#4260: Remove
enableTimeout()
(this.enableTimeout()
) from the context object (@craigtaub)✨ WORKAROUND: Replace usage of
this.enableTimeout(false)
in your tests withthis.timeout(0)
.#4315: The
spec
option no longer supports a comma-delimited list of files (@juergba)✨ WORKAROUND: Use an array instead (e.g.,
"spec": "foo.js,bar.js"
becomes"spec": ["foo.js", "bar.js"]
).#4309: Drop support for Node.js v13.x line, which is now End-of-Life (@juergba)
#4282:
--forbid-only
will throw an error even if exclusive tests are avoided via--grep
or other means (@arvidOtt)#4223: The context object's
skip()
(this.skip()
) in a "before all" (before()
) hook will no longer execute subsequent sibling hooks, in addition to hooks in child suites (@juergba)#4178: Remove previously soft-deprecated APIs (@wnghdcjfe):
