Lua scripts support

Reason

Default test has simple count of right answers (one error in 1toN will be 0). User can create own logic of results calculating.

Examples

Default alghorithm of question (type 'one answer')

in fact it counts inside ruby because of performance but I want to show principle of counting

local result = 0

for key, _ in pairs(USER_ANSWERS) do
    if TRUE_ANSWERS[key] == 'true' then
        result = 1
    end
end

return result

Limited question (user answer points will be decrease over time)

local result = 0

for key, _ in pairs(user_answers) do
    if true_answers[key] == 'true' then
        result = 1
    end
end

if compare_dates(DATE_NOW, '05/08/2021') == -1 then
    return result/2
else
    if compare_dates(DATE_NOW, '05/08/2021') == 1 then
        return result/3
    end
end

return result

In the future, it will be possible to create your own profile variables and use from instead of inline values

Examples was used global varibales (G_DATE_NOW, G_TRUE_ANSWERS, G_ALL_USER_ANSWERS) and helper functions (to_date). More about them in testlance-script
