This tarball contains the official test scripts for Lua 5.1.
|
||||
Unlike Lua itself, these tests do not aim portability, small footprint,
|
||||
or easy of use. (Their main goal is to try to crash Lua.) They are not
|
||||
intended for general use. You are wellcome to use them, but expect to
|
||||
have to "dirt your hands".
|
||||
|
||||
The tarball should expand in the following contents:
|
||||
- several .lua scripts with the tests
|
||||
- a main "all.lua" Lua script that invokes all the other scripts
|
||||
- a subdirectory "libs" with an empty subdirectory "libs/P1",
|
||||
to be used by the scripts
|
||||
- a subdirectory "etc" with some extra files
|
||||
|
||||
To run the tests, do as follows:
|
||||
|
||||
- go to the test directory
|
||||
|
||||
- set LUA_PATH to "?;./?.lua" (or, better yet, set LUA_PATH to "./?.lua;;"
|
||||
and LUA_INIT to "package.path = '?;'..package.path")
|
||||
|
||||
- run "lua all.lua"
|
||||
|
||||
|
||||
--------------------------------------------
|
||||
Internal tests
|
||||
--------------------------------------------
|
||||
|
||||
Some tests need a special library, "testC", that gives access to
|
||||
several internal structures in Lua.
|
||||
This library is only available when Lua is compiled in debug mode.
|
||||
The scripts automatically detect its absence and skip those tests.
|
||||
|
||||
If you want to run these tests, move etc/ltests.c and etc/ltests.h to
|
||||
the directory with the source Lua files, and recompile Lua with
|
||||
the option -DLUA_USER_H='"ltests.h"' (or its equivalent to define
|
||||
LUA_USER_H as the string "ltests.h", including the quotes). This
|
||||
option not only adds the testC library, but it adds several other
|
||||
internal tests as well. After the recompilation, run the tests
|
||||
as before.
