This library does two things:
- Test output is pretty printed.
- Equality assertions are also diffed.
Version 0.8.0 and later of humane-test-output requires Clojure 1.8.0 or later.
This test output formatting works great with Emacs and cider 0.10 or lower, and when running Leiningen in a console. However, some IDEs are also bashing in their own versions of test formatting.
I do not recommend using this with cider 0.11.0 or greater or with Cursive, or LightTable, or any other IDE.
To activate it you will need to call pjstadig.humane-test-output/activate!
.
The preferred way to do this with Leiningen is to use an injection in
the :user profile in your ~/.lein/profiles.clj:
{:user {:dependencies [[pjstadig/humane-test-output "0.8.1"]] :injections [(require 'pjstadig.humane-test-output) (pjstadig.humane-test-output/activate!)]}}
If you are on a mixed team and some members need to disable humane test
output, they can define the INHUMANE_TEST_OUTPUT
environment variable,
though again it’s better for each user to enable it in their own
~/.lein/profiles.clj.
Once humane-test-output is activated, instead of this:
FAIL in (a-test) (humane_test_output_test.clj:7) FIXME, I fail. expected: (= {:foo :bar, :baz :quux, :something "a long string?", :another-key "and another value"} {:fo :bar, :baz :quux, :something "a long string?", :another-key "and another value"}) actual: (not (= {:another-key "and another value", :foo :bar, :something "a long string?", :baz :quux} {:another-key "and another value", :something "a long string?", :fo :bar, :baz :quux})) FAIL in (a-test) (humane_test_output_test.clj:11) FIXME, I fail. expected: (= {:foo :bar, :baz :quux} {:foo :bar, :baz :quux} {:fo :bar, :baz :quux}) actual: (not (= {:foo :bar, :baz :quux} {:foo :bar, :baz :quux} {:fo :bar, :baz :quux})) FAIL in (a-test) (humane_test_output_test.clj:14) FIXME, I fail. expected: (list? foo) actual: (not (list? {:another-key "and another value", :foo :bar, :something "a long string?", :baz :quux}))
You get this:
FAIL in (a-test) (humane_test_output_test.clj:7) FIXME, I fail. expected: {:another-key "and another value", :foo :bar, :something "a long string?", :baz :quux} actual: {:fo :bar} diff: - {:baz :quux, :something "a long string?", :foo :bar, :another-key "and another value"} + {:fo :bar} FAIL in (a-test) (humane_test_output_test.clj:10) FIXME, I fail. expected: {:foo :bar, :baz :quux} actual: {:fo :bar, :baz :quux} diff: - {:foo :bar} + {:fo :bar} FAIL in (a-test) (humane_test_output_test.clj:13) FIXME, I fail. expected: (list? foo) actual: (not (list? {:another-key "and another value", :foo :bar, :something "a long string?", :baz :quux}))
BONUS FEATURE
A test containing (is (= oops-i-only-gave-one-argument))
will throw an
exception.
It is not necessary to activate humane-test-output with ClojureScript, but the behavior should be much the same as with Clojure.
