How to test a function where the first arg is Data

[shinokada]

The first test works using Data and result().
But I'm not sure how to test the second one. The function insert_blank_above_a takes two arguments, input and a string.
How to test a function that takes more than one arguments?
I have functions with three, four arguments as well.

Can I use Data as a argument?

Describe 'Space editor'
  Data
    #|foo
    #|bar
    #|baz
  End

  Describe 'double_space'
    It 'outputs no more than one blank line between lines of text'
      result() {
        %text
        #|foo
        #|
        #|bar
        #|
        #|baz
      }

      When call double_space 
      The output should eq "$(result)"
    End
  End

  Describe 'insert_blank_above_a'
    It 'outputs no more than one blank line between lines of text'
      result() {
        %text
        #|foo
        #|bar
        #|
        #|baz
      }

      When call insert_blank_above_a Data bar
      The output should eq "$(result)"
    End
  End
End

You have used the Data directive in the wrong way.

As you can see from the docs the Data block MUST precede the When directive, so in your case it should be:

Data
  #|foo
  #|bar
  #|baz
End

When call insert_blank_above_a Data bar
The output should eq "$(result)"

However, i don't understand what you want to do...
The insert_blank_above_a needs 2 parameters that change every time?

Maybe you need the Parameters directive?

Data[:*] vs Parameters[:*]

The difference is:

• Data directives: Passes data through STDIN (i.e. awk, cat)
• Parameters directives: Data is available as a parameter ($1..$N)
