Can't run tests in namespaces defined with underscores

[ikappaki]

Hi,

I can't seem to be able to run tests whose namespace is in camecase

To reproduce

1. create the following test structure in the basilisp codebase

.
└── test1
        ├── __init__.py
        └── issue
                ├── __init__.py
                └── a_test.lpy   

2. In a_test.lpy, create a namespace matching the filename in camel case (which is valid)

(ns test1.issue.a_test
  (:require [basilisp.test :refer [deftest is]]))

(deftest abc-test
  (is (= 5 6)))

3. Run the test in that directory, no tests are either detected or ran

> basilisp test test1
================================================================== test session starts ===================================================================

The same works as expected if you switch the _ with -, i.e. from test1.issue.a_test to test1.issue.a-test:

(ns test1.issue.a-test
  (:require [basilisp.test :refer [deftest is]]))

(deftest abc-test
  (is (= 5 6)))

> basilisp test test1

test1\issue\a_test.lpy F                                                                                                                            [100%]

FAIL in (abc-test) (a_test.lpy:5)
    Test failure: (= 5 6)

    expected: 5
      actual: 6

The same also works in Clojure.

Thanks
