+Testing
+-------
+
+::
+
+    pyenv 3.7.3 2.7.18
+    python3 -m venv venv
+    . venv/bin/activate
+    npm install
+    python -m pip install tox
+    tox
+
+If you don't have the Java runtime installed, you will receive a nasty message::
+
+    No Java runtime present, requesting install.
+
+And you will be presented a system dialog to "No Java runtime present, requesting install."
+
+If you would rather not do this, you enable an environment variable to skip tests
+requiring the Java runtime like this::
+
+    PIPELINE_SKIP_JAVA=1 tox
+
+Or, just export so you don't have to add that before each tox invocation::
+
+    export PIPELINE_SKIP_JAVA=1
+    tox -e py37-django20
+
