Test Runner

Calva provides commands that make running your Clojure tests easier.


Since the test commands utilize cider-nrepl, they only work with Clojure, not ClojureScript. See this issue for more details.

Test Commands

Command Shortcut Description
Run All Tests ctrl+alt+c shift+t Runs all tests
Run Failing Tests ctrl+alt+c ctrl+t Runs the tests that failed
Run Tests for Current Namespace ctrl+alt+c t Runs the tests for the current namespace. If not a -test namespace, tests for the current namespace plus its corresponding <current-namespace>-test namespace will be run.
Run Current Test ctrl+alt+c ctrl+alt+t Runs the test at the cursor. This includes a defn with a :test in its metadata, a defn defined in a with-test, and a deftest.

Test on Save

You can enable the Calva setting "Test on Save" to have tests for the current namespace run on file save.


Tests Are Not Found

If you have tests in a test directory separate from your source directory, and those tests are not being found by the test runner, make sure the test directory is included in your paths. This will not be the case by default with a tools.deps (deps.edn) project. If your project is a tools.deps project, you can create an alias in your deps.edn file with :extra-paths that includes "test" (or the name of your test directory).

{:aliases {:dev {:extra-paths ["test"]}}}

Having added the above to your deps.edn, when you jack-in, choose the :dev alias and the test directory will be added to your paths, which will allow tests located in the directory to be found by the test runner.
