Trailing empty lines are ignored by design?

[kai2nenobu]

I wrote following examples to test a trailing empty line.

Describe "Demo"
  trailing_empty_line() {
    printf "1\n2\n\n"
  }

  It "Last empty line is not counted"
    When call trailing_empty_line
    The lines of output should eq 3
  End
  It "Last empty line is not set"
    When call trailing_empty_line
    The 3rd line of output should eq ""
  End
End

However, these examples failed as below.

$ shellspec --format tap
1..2
not ok 1 - Demo Last empty line is not counted # FAILED
# (in specfile spec/sample_spec.sh, line 8)
# When call trailing_empty_line
# The lines of output should eq 3
# 
#   expected: 3
#        got: 2
# 
not ok 2 - Demo Last empty line is not set # FAILED
# (in specfile spec/sample_spec.sh, line 12)
# When call trailing_empty_line
# The 3rd line of output should eq 
# 
#   expected: ""
#        got: <unset>
# 

This shellspec behavior is intended one? Can I test trailing empty lines by shellspec?

Strange...

Seems like testing the output instead works as expected:

#shellcheck shell=sh

Describe "Demo"
  trailing_empty_line() {
    printf "1\n2\n\n"
  }

  It "Last empty line is not counted"
    When call trailing_empty_line
    The lines of output should eq 3
  End

  It "Last empty line is not counted"
    When call trailing_empty_line
    The output should eq "$(trailing_empty_line)"
  End
  
  It "Last empty line is not set"
    When call trailing_empty_line
    The 3rd line of output should eq ""
  End
End

Output

$ shellspec ./test.test.sh
Running: /usr/bin/bash [bash 4.4.12(3)-release] {--jobs 3}
F.F

Examples:
  1) Demo Last empty line is not counted
     When call trailing_empty_line

     1.1) The lines of output should eq 3

            expected: 3
                 got: 2

          # ./test.test.sh:10

  2) Demo Last empty line is not set
     When call trailing_empty_line

     2.1) The 3rd line of output should eq

            expected: ""
                 got: <unset>

          # ./test.test.sh:20
