=== Example 2: Using Lua ===
We can also write tests using Lua. (Example by WS, 3/2011.)
<context mode="mkiv" source="yes">
\starttextstartTEXpage
\ctxlua{test = true}
Test is \ctxlua{commands.testcasedoifelse(test)}{True}{False}.
\ctxlua{test = false}
Test is \ctxlua{commands.testcasedoifelse(test)}{True}{False}.\stoptextstopTEXpage
</context>
