Anyone know how to generate random letter or number in watir?

[Dms]

I think it would be very useful for test where need to save different
login each time when run test.
If anyone know, share your ideas, please.
Thanks, Dmitry.

For random generation of letters and numbers the following method
should work for you.
Typically for logins, i would just timestamp the login name i.e.
"qatest_#{Time.now.strftime("%m%d%Y%H%M%S")}@foo.com"

#------------------------------------------------------------------------------
# Method: random_alphanumeric
# In: string size
# Return: get a random string that is num characters long
#------------------------------------------------------------------------------
def String.random_alphanumeric(size=16)
s = ""
size.times { s << (i = Kernel.rand(62); i += ((i < 10) ? 48 : ((i
< 36) ? 55 : 61 ))).chr }
return s
end

Hi,

If you need unique values, why don't you use the current date\time

require 'date'
date_and_time = Time.now.asctime

Ruby allows you to do lots with random numbers/letters

Rand(10)

will return a random number (like 1, 2)

rand() returns a random decimal (like 0.6891121414121)

rand(9999) returns random digits (like 3212)

pick a random item in an array

myarray = ['dog','cat','orange']

myarray[rand(myarray.length)]

output like 'cat'

google search yielded this nice for generating random lowercase letters

Array.new(6) { (rand(122-97) + 97).chr }.join

Output like "aydshg"

Hope that helps.

Hi Dmitry,
You've already got lots of answers, but if it would help, I could send you our modules that do random characters and random names.

Thanks a lot to everyone. Array.new(6) { (rand(122-97) +
97).chr }.join that solution was great for me.

for random test data i use the gem randomdata and faker both are good
for building random data.
