Situation

Usually you run tox like this:

tox -e py36

That works, all fine. However, it runs the complete test suite. If you work on a single test function, it is currently not possible to run this alone. You always have to run the complete test suite.

Proposed Solution

I would propose the following small patch to introduce the posargs argument:

diff --git c/tox.ini i/tox.ini
index e172f8a..f7b1b2e 100644
--- c/tox.ini
+++ i/tox.ini
@@ -5,7 +5,7 @@ envlist =
     pypy
 
 [testenv]
-commands = py.test
+commands = py.test {posargs:}

This makes it possible to run tox only for the test function test_should_bump_major:

tox -e py36 test_semver.py::test_should_bump_major

With this single patch, it is even possible to use it for the setup.py script:

python3 setup.py test -a "-e py36 test_semver.py::test_should_bump_major"

Without the posargs argument tox has to run the
*complete* test suite. With this patch, you can
pass a test file and a test function. That allows tox
to only run this specific test function. For example:

$ tox -e py36 test_semver.py::test_should_bump_major

Fix #146: improve tox.ini/.travis.yml

* Changes in tox.ini:
  * add posargs for pytest. This allows to run only a single test function.
  * Rename py.test -> pytest as the old spelling py.test will be deprecated in the future.

* Changes in .travis.yml:
  * Add cache for pip to speed up things a little bit
  * Add tox as a installation requirement
  * Replace setup.py with tox as it discouraged in https://tox.readthedocs.io/en/latest/example/basic.html#integration-with-setup-py-test-command
