 **Do not run these tests on installations with important data, because you might lose it.**
 Since these tests were written with this expectation, all the VMs with a name starting with `test-` on the installation are removed during the process, and all the tests are recklessly started from dom0, even when testing VM components.

+Most of the tests are stored in the [core-admin repository](https://github.com/QubesOS/qubes-core-admin/tree/master/qubes/tests) in the `qubes/tests` directory. 
 To start them you can use standard python unittest runner:
-    python -m unittest -v qubes.tests
+    python3 -m unittest -v qubes.tests
 Or our custom one:
-    python -m qubes.tests.run -v
+    python3 -m qubes.tests.run -v
 
 Our test runner runs mostly the same as the standard one, but it has some nice additional features like color output and not needing the "qubes.test" prefix. 
 It also has the ability to run lone selected template tests.

 ### Adding a new test to core-admin
-After adding a new unit test to [core-admin/tests](https://github.com/QubesOS/qubes-core-admin/tree/master/tests) you'll have to make sure of two things:
-
-1. That the test will be added to the RPM file created by [QubesBuilder](/doc/qubes-builder/). For this you need to edit the [core-admin/tests/Makefile](https://github.com/QubesOS/qubes-core-admin/tree/master/tests/Makefile)
-2. That the test will be loaded by [core-admin/tests/\_\_init\_\_.py](https://github.com/QubesOS/qubes-core-admin/tree/master/tests/__init__.py)
-
-#### Editing the Makefile
-To add your tests, you must append these two lines to the end of the makefile, which will copy your test and its compiled version to the right directory in the RPM file. 
-If your test is `example.py`, the appended lines would be:
-
-    cp example.py $(DESTDIR)$(PYTHON_TESTSPATH)
-    cp example.py[co] $(DESTDIR)$(PYTHON_TESTSPATH)
+After adding a new unit test to [core-admin/qubes/tests](https://github.com/QubesOS/qubes-core-admin/tree/master/qubes/tests) you'll have to include it in [core-admin/qubes/tests/\_\_init\_\_.py](https://github.com/QubesOS/qubes-core-admin/tree/master/qubes/tests/__init__.py)
