-(<i>The Selenium plugin, ``--with-selenium``, is enabled by default when using pytest to run test classes that inherit the [BaseCase](#seleniumbase_basic_usage) class, thanks to [pytest.ini](https://github.com/seleniumbase/SeleniumBase/blob/master/pytest.ini). You can do the same for nosetests by adding ``with-selenium=1`` under ``[nosetests]`` in a [setup.cfg](https://github.com/seleniumbase/SeleniumBase/blob/master/examples/setup.cfg) file located in the folder where you call nosetests.</i>)

-(NOTE: You can interchange **nosetests** with **pytest**.)

-```bash
-cd examples/

-nosetests my_first_test.py --with-selenium --browser=chrome
+nosetests my_first_test.py --browser=firefox
 
-nosetests my_first_test.py --with-selenium --browser=firefox
+pytest my_first_test.py --demo_mode --browser=chrome
 
-nosetests my_first_test.py --with-selenium --browser=phantomjs
+nosetests my_test_suite.py --with-testing_base -s
 ```
-After the test completes, in the console output you'll see a dot (``.``) on a new line, representing a passing test. (On test failures you'll see an ``F`` instead, and on test errors you'll see an ``E``). It looks more like a moving progress bar when you're running a ton of unit tests side by side. This is part of nosetests. After all tests complete (in this case there is only one), you'll see the "``Ran 1 test in ...``" line, followed by an "``OK``" if all nosetests passed. The ``--with-selenium`` option is required for running GUI tests with nosetests (not needed when using pytest). If no browser is specified, Chrome will become the default. The ``-s`` option is optional, and that makes sure that any standard output is printed immediately on the command line when tests have print statements in them, which makes debugging much easier.
