Line 28:
A tactic, for dealing with older bugs, is to plan to run special extra test data to activate code areas, or show debug-display output, where new Lua script might be added, to provide a [[sanity check]] that the affected areas are functioning soundly, before adding too much new, detailed logic. In most cases, note: "''proofreading is the fastest form of testing"'' if having the patience, or mental memory power, to review the details of older source code. However, another tactic is to reserve specific test-data values to trigger debug-display code which dumps the values of all related data to the screen, or provides a call-tree list to ensure the logic flows into various function sections as expected. In many cases, human memory cannot cope with details beyond 5-9 variables, and so debug-display becomes an easier option, despite the extra time needed to write the debug-print statements into the Lua module. Be careful to proceed slowly, because once extensive amounts of new Lua script are added, then it can become a puzzling guessing game whether the problems were caused by "all the new stuff" rather than by pre-existing bugs in the older Lua script.
== Using
The English wikipedia has the [[mw:Extension:TemplateSandbox|Template Sandbox]] extension installed. There is a
=== How to use "Template Sandbox" to develop scribuntu module? ===
Let's take a practical example. for this example, assume your user name is "Lua Developer". Let's say you want to test a bug-fix or enhancement to the [[Module:String|String]] module. There are two reasons you can't do it directly: this module contains functions that are used by hundreds of templates, transcluded in milions of articles. Any bug will present a huge disruption to Wikipedia. The 2nd reason is more prosaic: because this module is so central, it is also protected, and our "Lua Developer" user does not have the required permissions to modify this module.
