If the value is a null value, VarToStr returns an empty string.
Hi,
What scripting language your test project is based on?
Alex,
I am using Keywords tests but project are Javascript based
in the KW test I have if the on-screen object Equals "" Or Equals null but this doesn't work
I was looking to avoid writing another code snippet but the JS code would be something like
if (!var) {
//do this
}
Hi,
I am not an expert with JavaScript, but to my understanding when a variable is assigned empty string or null value then this means that it is not empty.
You may consider aqObject.EmptyVariant or classic check like
if ('undefined' == typeof(<parameter>))
P.S.
if ('undefined' == typeof(<parameter>)) ' condition will not be met for null and empty string and will meet if parameter is missed at all
if (!var) ' this will work for null but not for empty string if I am not mistaken
I.e. the former check should be used when null is acceptable value for the parameter and the latter when it is not.
sonya_m this answer was helpful is so much as it confirmed what I was thinking
The issue I have here is there the DDT loop should be intelligent enough to expect an empty or null string input and not throw an exception, furthermore, we should be given easier ways to test for this in KW rather than resorting to code or wondering why a string vs a string is a type mismatch
but thanks for your input guys...
