I just released version 1.1 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 Marmalade and 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 1.0
- Buttercup now sports a full reporter interface, in case you want to write your own reporter. By default, there is a batch and an interactive reporter.
- Reporters now display failed tests properly at the end of the test run, together with a properly-formatted backtrace.
- Pending specs and disabled suites as in Jasmine are now supported.
- Emacs 24.5 is now officially supported.
- There’s now a buttercup script to run the most common command line.
- Test runners are now autoloaded.
- Test discovery now ignores dot files and dot directories.
- Buttercup tests can now be instrumented with Edebug.
