-- Test director_exception for Lua
-- Tests exception handling with directors

require("director_exception")

-- Use the SWIG-provided helper function for cleaner code
-- swig_override(obj, methodName, func) - sets a method override

--print("=== Test 1: Director method that throws an error ===")
local foo1 = director_exception.Foo()
swig_override(foo1, "ping", function(self)
	error("MyFoo::ping() EXCEPTION")
end)

local laundered1 = director_exception.launder(foo1)
local ok, err = pcall(function()
	laundered1:pong()
end)
assert(not ok, "Exception should have been thrown")
--print("Caught expected exception: " .. tostring(err))
assert(string.find(tostring(err), "EXCEPTION") ~= nil, "Exception message should contain 'EXCEPTION'")

--print("\n=== Test 2: Director method that returns wrong type ===")
local foo2 = director_exception.Foo()
swig_override(foo2, "ping", function(self)
	return 12345 -- Wrong type: number instead of string
end)

local laundered2 = director_exception.launder(foo2)
local ok2, err2 = pcall(function()
	laundered2:pong()
end)
-- This might or might not throw depending on how strict the type checking is
--[[if not ok2 then
	print("Caught type mismatch error (expected): " .. tostring(err2))
else
	print("No error thrown for type mismatch (might be ok if auto-conversion happens)")
end]]

--print("\n=== Test 3: Normal director method call ===")
