selectors for tests

[nha]

From lein help test:

Run the project's tests.

Marking deftest or ns forms with metadata allows you to pick selectors to
specify a subset of your test suite to run:

   (deftest ^:integration network-heavy-test
     (is (= [1 2 3] (:numbers (network-operation)))))

Write the selectors in project.clj:

   :test-selectors {:default (complement :integration)
                    :integration :integration}

Arguments to this task will be considered test selectors if they are keywords,
otherwise arguments must be test namespaces or files to run. With no
arguments the :default test selector is used if present, otherwise all
tests are run. Test selector arguments must come after the list of namespaces.

A default :only test-selector is available to run select tests. For example,
`lein test :only leiningen.test.test/test-default-selector` only runs the
specified test. A default :all test-selector is available to run all tests.

Arguments: ([& tests])

It would be nice to have a :test-selector parameter in boot test as well (it allows filtering namespaces at the moment, but not individual tests as far as I know).

any plans on this?

Hi, i found that i can emulate such feature by using "filters" configuration option.

(deftask integration-test
  "Runs integration tests"
  []
  (comp (environ :env 
                 {:http-port "9000"
                  :database-url "jdbc:postgresql://localhost:32768/test?user=postgres&password=postgres"})
        (test :filters #{'(-> % (meta) (:integration))})))

That interesting, now i am not sure should this functionality be in core or not. Because it is so easy to implement different strategies of what tests/namespaces you want to run tests on.

I think the filters option actually filters functions, not namespaces. I was just trying to use it to exclude namespaces and while debugging noticed that it gets evaluated for every symbol in every namespace. Returning false doesn't stop the evaluation, and even if you return false for every symbol in a namespace it still prints "Testing namespace.foo".

Perhaps the documentation should be improved to make it clear that this doesn't filter namespaces, but rather functions?
