How to generate a Random Numeric String having 6 digits, in Gatling?
For example, I need to feed "123456" for an attribute in Gatling.
Thanks for the help.
You could start with what you've got and make the following change...
...filter(_.isDigit).take(6).mkString
...but I'd be more inclined toward the following.
(Random.nextInt(900000)+100000).toString
Note: For the 1st proposed solution, leading zeros are possible, "010203" for example. That's not the case for the 2nd. Not sure which is preferred.
Scala 2.13.x option:
util.Random.between(100000, 1000000)
//minimum (inclusive)--^ ^--maximum (exclusive)

NSArray from NSCharacterSet

When I'm trying
print(NSCharacterSet.URLQueryAllowedCharacterSet())
it prints
<__NSCFCharacterSet: 0x1759b900>
How do I make it more informative?
You can get a representation of the character set using bitmapRepresentation which could be queried. Or you could do basically the same thing with a loop over all characters and using characterIsMember:. The output is potentially big...
There isn't really a simple option or a generic concise output to what you're asking for. It isn't a common requirement.

How can I convert ereg expressions to preg in PHP?

eregi_replace('[0-9]+\.+[0-9]','',$cart['unit']);
How to change it to preg_replace?
I get an error: Warning: preg_replace() [function.preg-replace]: Unknown modifier '+' in ---
You can use your existing Regex almost unchanged in a preg_replace(). Just add delimiters and a case-insensitive modifier. You get
preg_replace('#[0-9]+\.+[0-9]#i','',$cart['unit']);
In fact, the case-sensitivity is irrelevant since your pattern only matches 0-9 and .
