They have a script (usually called test.lua) that exercises the module API using API calls and assert() calls to verify the results. It is also common practice in those modules to use print() to output information about the test progress and to use Lua comments to inform what is being tested to whoever reads the source.

Lua coercion rules are applied so that only nil and false all compare to false. assertNil (value) ¶ Aliases: assert_nil(), assertIsNil(), assert_is_nil() Assert that a given value is nil. assertNotNil (value) ¶ Aliases: assert_not_nil(), assertNotIsNil(), assert_not_is_nil() Lua is an extension programming language designed to support general procedural programming with data description facilities.

LuaUnit works with Lua 5.1, LuaJIT 2.0, LuaJIT 2.1 beta, Lua 5.2 and Lua 5.3 . It is tested on LuaUnit provides assertion for type testing (see Type assertions).

file = assert(io.open("no-file", "r")) --> stdin:1: no-file: No such file or directory Among many other things, a Lua-like assertmacro can be made that checks that a condition is true, and if it's not, an error is raised, in such a way that by just changing a definition, all assert's in the code can be instantly gone, resulting in no code generated for them. And if the assertion passes, the second parameter (the error message to local f = assert(io.open(filename, mode)) If the open fails, the error message goes as the second argument to assert, which then shows the message.

Send any issue to the Lua mailing list https://www.lua.org/lua-l.html lua_assert macro definition seems a bit confusing: In lua_lib.h: #if !defined(lua_assert) #define lua_assert(x) ((void)0) #endif But also in llimits.h /* internal assertions for in-house debugging */ #if defined(lua_assert) #define check_exp(c,e) (lua_assert(c), (e)) /* to avoid problems with conditions too long */ #define lua_longassert(c This technique can be used to register namespace-like functions and classes. It can be as deep as you want.

Lua performs run-time type checking on its built-in operations. For example, this code triggers a run-time error: > x = 5 + "ok" stdin:1: attempt to perform arithmetic on a string value However, unlike in languages like C, there is no built-in mechanism in Lua for type checking …

Its second argument, the message, is optional, so that if you do not want to say anything in the error message, you do not have to. Among many other things, a Lua-like assertmacro can be made that checks that a condition is true, and if it's not, an error is raised, in such a way that by just changing a definition, all assert's in the code can be instantly gone, resulting in no code generated for them. luassert extends Lua's built-in assertions to provide additional tests and the ability to create your own. You can modify chains of assertions with not. Check out busted for extended examples.
