I just released version 1.5 of Buttercup, the Behavior-Driven Emacs Lisp Testing framework.
Buttercup is a behavior-driven development framework for testing Emacs Lisp code. It is heavily inspired by Jasmine.
Installation and Use
Buttercup is available from MELPA Stable.
Example test suite:
(describe "A suite" (it "contains a spec with an expectation" (expect t :to-be t)))
Suites group tests, and suites can be nested. Contrary to ERT, suites can share set-up and tear-down code for tests, and Buttercup comes with built-in support for mocks in the form of spies. See the package homepage above for a full description of the syntax for test suites and specs.
Buttercup comes with a shell script to run the default discover runner. If used together with cask, cask exec buttercup will find, load and run test suites in your project.
Changes Since 1.4
- The new
assumeform makes it easier to skip tests when certain assumptions do not hold (thanks to Sebastian Wiesner for the patch!)
- Buttercup is now available in Debian 9 and Ubuntu 16.10 or later:
apt-get install elpa-buttercup(thanks to Sean Whitton!)
describeform now also takes a
:varargument to make variables available in the body, removing one level of nesting compared to a
- Pending specs are now tracked separately, making test run reports more easily readable
- And a number bug fixes
