Running mozharness on a local system is actually documented [1],
although I think that makes it sound harder than it actually is. I have
a run.sh script in the root of my mozharness checkout that looks like

#!/bin/bash

cd scripts

CONFIG_FILE=../configs/web_platform_tests/test_config.py
BUILD_ROOT=/home/jgraham/develop/gecko-dev/obj-x86_64-unknown-linux-gnu/dist
INSTALLER_URL=file://$BUILD_ROOT/firefox-34.0a1.en-US.linux-x86_64.tar.bz2
TEST_URL=file://$BUILD_ROOT/firefox-34.0a1.en-US.linux-x86_64.tests.zip

./web_platform_tests.py --no-read-buildbot-config --config-file
$CONFIG_FILE --installer-url $INSTALLER_URL --test-url $TEST_URL

Obviously for different testsuites you need different config files or
command lines, e.g. mochitest-plain would have something like

CONFIG_FILE=../configs/unittests/linux_unittest.py

and a final command like:

./desktop_unittest.py --no-read-buildbot-config --mochitest-suite plain
--config-file $CONFIG_FILE --installer-url $INSTALLER_URL --test-url
$TEST_URL --download-symbols true
