Run tests by tasks

[reify-raman-adlakha]

Not an issue but a suggestion.

Exercism Clojure track tests have metadata :task attached with values from 1 to n, each representing a task in the exercise. While working through tasks sequentially, I prefer running tests specific to the current task. Running these tests using :only (like lein test :only ns/test_function) is tedious since I must execute each test individually. I wanted a way to run all tests associated with a task at once.

After studying how test selectors work, I added a test-selector in project.clj. Now I can run all tests for a specific task—for example, task 2 —using lein test :task 2

Add the :task test-selector in any project that has tests defined with ^{:task 1} type markers.

I hope you find it useful.

                     ;; lein test :task n ;; where n is the task number
                     :task (fn [m task]
                             (when-let [task-value (get m :task)]
                               (= task task-value)))})

I like the idea. @tasxatzial what about you?

[tasxatzial]

Yes, they posted this on discord and I redirected them here.

We can also do something similar for practice exercises. Run by function, for instance.

Great idea.
