+
+1. copy `phpunit.xml.dist` file into `phpunit.xml` file
+2. in the `phpunit.xml` file:
+ * uncomment part, where `LIVE_TEST_ENDPOINT`, `LIVE_TEST_USERNAME` and `LIVE_TEST_PASSWORD` environment variables are defined
+ * populate them with the corresponding values
+3. write the desired LIVE test in the `ApiTest::testLive` method (e.g. `$api->addWorklog('JRA-12', '12m');`)
+4. run it using `vendor/bin/phpunit --filter testLive` command
