Re: [ANN]: Matcha, a library for composable test assertions with human readable error messages
This looks pretty cool! One thing I wonder, though, why am I seeing all
these \n values rather than actual newlines in the actual value, which
would make the output so much easier to read? Is there any way to configure
or use it differently that would avoid this issue? (This is with lein test
right after adding the dependency to my project.clj and changing one test
to use matcha). Also, the expected message looks a little broken, should
it not instead say something like expected: a map with entry :status that
equals 201? (there is no word between that and 201):
FAIL in (starting-and-stopping-production-server-works-as-expected)
(httpkit_test.clj:17)
start-production-server causes HttpKit and Hazelcast to start
expected: a map with entry :status that 201

Matcha lets you write flexible, composable test assertions with human

library.
As a quick example, you might build up a matcher that says this map has 5
elements, and the :foo key must be greater than 10 like so:
```
(require '[matcha :as m])
(deftest my-map-test
(m/is (m/and (m/has-entry-that :foo (m/ 10)) (m/has-count 5))
my-map))
```
If that ever returns false, you'll get an *excellently* readable error
message, detailing exactly why it failed.
Matcha is completely test framework independent, though it does ship with
clojure.test support out of the box. Wiring it up to your test framework of
choice should take only a few minutes.

Oh, sorry, here is my actual test: (m/is (m/has-entry-that :status (m/= 200)) (http/get http://localhost:12081/idp/status;)) -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: [ANN]: Matcha, a library for composable test assertions with human readable error messages
The API docs need a little love too... It seems that the examples for has-nth are actually for has-count; the second example for both has-denominator and has-numerator are actually about nil?, the examples for has-key appear to actually be testing the values, not the keys, the examples for not are reversed... Actually, rather than make you wade through and figure out what I mean, I will just submit a pull request, and suggest some improved wording and more disambiguation while I am at it. Someone will need to double check the examples I came up with for has-nth because I came up with them by inspecting the code, and I am new to this package. Also, for clarity, I proposed adding the following example for matcha/every? (matcha/run-match (matcha/every? (matcha/= 1)) []) ; = passes Is this true? An empty sequence does not have any items which fail, so I would expect so. I am not sure if the isa? documentation is correct. It looks backwards to me, but I may just not understand what isa? is trying to test. Which suggests it could and should be clarified, at least! Anyway, please take my suggestions and questions in the spirit in which I intend them: Excitement about this new package, and a desire to help it get even better! -James On Monday, May 25, 2015 at 3:27:13 PM UTC-5, tcrayford wrote: Matcha lets you write flexible, composable test assertions with human friendly error messages.
