nREPL middleware to interact with Midje

The goal of midje-nrepl is to provide a better support for interacting with Midje from Clojure tools such as Cider. It offers a set of features for running Midje tests, getting report information and formatting facilities to be used within a nREPL session.


With Cider and Emidje

If you are using Cider and Emidje within Emacs, just call cider-jack-in and the appropriate midje-nrepl's version will be injected in the REPL automatically.

If you are connecting to an already running REPL process, midje-nrepl should be added explicitly. Add the following, either in your project's project.clj, or in the :user profile found at ~/.lein/profiles.clj:

:plugins [[cider/cider-nrepl "0.18.0"]
[nubank/midje-nrepl "1.0.0"]]

Notice that currently only Leiningen is supported.

Available features

  • Inhibit Midje facts from being run on certain nREPL operations such as eval, load-file, refresh, refresh-all and warm-ast-cache (when refactor-nrepl) is available on the project's classpath. This is useful specially on large projects with slow and heavy tests, where those run inadvertently as a side effect of the aforementioned operations.
  • Provide a set of operations for dealing with Midje tests: to run a given fact, a set of facts in a given namespace, all facts defined in the project, allow re-running non-passing tests, etc.
  • Provide information about project's test paths and test namespaces declared within those paths.
  • Support auto-formatting tabular facts.


An extensive changelog is available here.


Type make test to run unit tests (those under the test directory). Type make test-integration to run integration tests (those under the integration directory). They are useful for exercising a real communication with a nREPL server running within a fake project. If you are working interactively on a REPL and want to run integration tests, type make setup-integration to set-up the needed stuff. Type make test-all to run both kinds of tests.
