How to call Function argument into another ruby script

ruby-talk
1

Consider I have a ruby file called library.rb.

In which i defined a function like this :

def Name(testcase, result)
pdf = PDF::Writer.new
testcase= $testcase
pdf.text $testcase, :font_size => 72, :justification => :center
result= $result
pdf.text $result, :font_size => 72, :justification => :center
end

now i have another ruby file named web.rb which calls thus library.rb.

My Problem is I need to pass these arguments separately.

Means , I need to call Testcase argument firstly and then after many
conditions I need to pass result as Pass or fail.

The Testcase is like I am doing a web automation and the library.rb is
the report part where From the web.rb I need to pass the testcase name
and then at the end I need to pass end result.

Please help me to do this.

You could create a class in library.rb that receives a testcase in the
constructor, and has a method report which receives the result and
does what you are doing in the above method. Then in your web.rb you
will create an instance of that class passing the testcase, then you
do your thing, and at the end you call the report method. Something
like:

#library.rb
class Report
  def initialize testcase
    @testcase = testcase
  end

  def report result
    pdf = PDF::Writer.new
    pdf.text @testcase, :font_size => 72, :justification => :center
    pdf.text result, :font_size => 72, :justification => :center
  end
end

#web.rb
require 'library'

report = Report.new testcase
#... your testing stuff
report.report result

Just a minor nitpick: the file should not be called "library.rb"
because that is way too unspecific. In your example it could be
called "report.rb" or "report_test.rb" or "test-report.rb".

Hi Jesus,

When I run I am getting an error "undefined local variable or method
`testcase' for main:Object (NameError)"

I will share u my both scripts :

#testcase_lib.rb

require 'rubygems'
require 'pdf/writer'
require 'pdf/simpletable'

class Report
  def initialize testcase
    @testcase = testcase
  end

  def report result
    pdf = PDF::Writer.new
    pdf.select_font "Times-Roman"
    pdf.text @testcase, :font_size => 72, :justification => :center
    pdf.text result, :font_size => 72, :justification => :center
    pdf.save_as("Report.pdf")
  end
end

#testcase.rb

require 'rubygems'
require 'pdf/writer'
require "testcase_lib"

report = Report.new testcase

@testcase = "Login Test";

report.report result
result = "PASS"

What I was trying to do is, when i run I want to pass the testcase name
to testcase_lib.rb, which will be saved to PDF, after running the
testcase, the result Pass or Fail will be passed as result. I tried for
2 days but no matter what its not working. Please help

Looks like you are trying to use variables before they are defined.

Try this;

#testcase.rb

require 'rubygems'
require 'pdf/writer'
require "testcase_lib"

testcase = "Login Test";
report = Report.new testcase

result = "PASS"
report.report result

If I understand that correctly, what you're looking for is actually textbook partial application or currying/schönfinkeling. If you're using Ruby 1.9 you can use Proc#curry directly like so:

# unbind the method and convert it to Proc to use #curry
report = method(:Name).to_proc.curry[testcase]

# and later apply the second argument
report[result]

Alternatively, you can also implement partial application like this:

# define a lambda that that captures your test case in a closure so you can pass the result later
report = lambda { |result| Name(testcase, result) }

# later, execute the lambda with your result
report[result]

Note that in your case it is probably better to follow the advice posted by Jesus and Robert for a cleaner solution. It's just that functional programming is fun, and your question really seemed to call for partial application!

Hi Jesus,

   pdf.save_as("Report.pdf")
end
end

#testcase.rb

require 'rubygems'
require 'pdf/writer'
require "testcase_lib"

Here you're passing the variable 'testcase' which you have not defined before.

report = Report.new testcase

@testcase = "Login Test";

You probably want something like this:

report = Report.new "Login Test"

Or else:

testcase = "Login Test"
report = Report.new testcase

Here you will run into the same error; always define your variables before you use them!

Wow...thanks a lot it worked. So my another doubt arises. This was for 2
variables, similarly if i have for eg :

#testcase_lib.rb

def Name(testcase, module1, module2, final_result)
pdf = PDF::Writer.new
testcase= $testcase
pdf.text $testcase, :font_size => 72, :justification => :center
module1= $module1
pdf.text $module1, :font_size => 72, :justification => :center
module2= $module2
pdf.text $module2, :font_size => 72, :justification => :center
final_result1= $final_result1
pdf.text $final_result1, :font_size => 72, :justification => :center
pdf.save_as("chunky.pdf")
end

Firstly I need to print the Testcase name. Then module 1 will be run and
needs to print the module1 result then module2 result and then finally
the final result.

I have got experience in WATIR but I never used these classes and all in
WATIR, It was a real help from u guys and please help me to solve this
issue also.

This is my entire script

pdf.move_pointer(90)

    tab4.shade_color = Color::RGB.new(0,220,0)

    if $login_result == "PASS" && $checkout_result == "PASS" &&
$signout_result == "PASS"
    $result = "PASS"
    tab4.shade_color = Color::RGB.new(0,220,0)
    else
    $result = "FAIL"
    tab4.shade_color = Color::RGB.new(220,0,0)

        data = [

          ]
        tab4.data.replace data
        tab4.render_on(pdf)
end
pdf.save_as("Report.pdf")

and these are the variables i need to pass from the testcase

variables = $tc_name, $version, $tester, $login_result,
$checkout_result, $signout_result

<snip/>

Please use a public pastebin or a Gist for such a lengthy piece of
code. That makes it much easier to read. On first glance there seems
to be a lot of repetitive patterns in there so you may be able to
shrink this considerably.

Kind regards
