 Instead of setting the environment by the os (or `os.environ` as well) you can use the :mod:`pwb`
 wrapper script to set it::
 
-    pwb PYWIKIBOT_TEST_AUTORUN=1 script_tests -v TestScriptSimulate.test_archivebot
+    pwb PYWIKIBOT_TEST_WRITE=1 script_tests -v TestScriptSimulate.test_archivebot
 
 The assignment can be omitted and defaults to 1. The following is equal to the line above::
 
-    pwb PYWIKIBOT_TEST_AUTORUN script_tests -v TestScriptSimulate.test_archivebot
+    pwb PYWIKIBOT_TEST_WRITE script_tests -v TestScriptSimulate.test_archivebot
