Hi,

I use Ruby and Watir

I have a method:

def does_the_html_include(target)
puts "HTML text of #{target} is being verified"
if target.kind_of? String
return $browser.text.include?(target)
elsif target.kind_of? Regexp
return $browser.text.match(target)
end
end


I wrap this up in a logger

def test_results(result, *msg)
#make true explicit, everything else I am seeing as a failure
if result == true
test_status = @test.add_element 'teststatus'
test_status.text = 'PASS'
else
fail = @test.add_element 'teststatus'
fail.text = 'FAIL'
fail_msg = @test.add_element 'failmessage'
fail_msg.text = msg
end
end


However, when I don't want HTML text to appear, eg: an error. I want
to do something better than this

boolean = does_the_html_include('You appear to have an active
account')
$test.test_results(!boolean, 'already have registered account')

Any ideas?

Cheers

Aidy

This is a very bad idea, as only false and nil are false. Your code
above will especially break with the test because the regexp match will
either return nil or a MatchData object - which both will make "result
== true" false.

I am not sure what exactly it is that you want to improve. Do you
dislike the local variable?

def test_results(msg)
if yield
# test ok
else
# not ok
end
end

test_results "foo" { does_the_html_include('You appear to have an active
account') }

Cheers

Yes. I am writing two lines when I should be writing one.

Could you give a brief explanation of this code please?

Well, if that's all that bothers you - you can easily inline it:

$test.test_results(!does_the_html_include('You..') , 'already have
registered account')

The method invokes the block and uses the result to determine what to
do (if or else).

Does that help?

Kind regards

Surely does. Thanks Robert, your a linguist.

Hm, not sure whether that was irony or not.

Maybe this helps:

irb(main):001:0> def test(yes,no)
irb(main):002:1> if yield
irb(main):003:2> puts yes
irb(main):004:2> else
irb(main):005:2* puts no
irb(main):006:2> end
irb(main):007:1> end
=> nil
irb(main):008:0> test("ok", "not ok") { 1 > 2 }
not ok
=> nil
irb(main):009:0> test("ok", "not ok") { 1 < 2 }
ok
=> nil
irb(main):010:0> test("ok", "not ok")
LocalJumpError: no block given
from (irb):2:in `test'
from (irb):10
from :0
irb(main):011:0>

Kind regards

Wasn't ironic Robert, I studied #yield and blocks when you mentioned
them. It was exactly what I was looking for. Probably one of the most
powerful assets of Ruby and I missed it.

Ah! I'm glad I could help. And, yes, blocks (anonymous functions) are
one of the best features in Ruby - totally agree.

Kind regards
