How to get coverage on multi-line strings

[aareman]

How to get kcov to pick up a multiline string. Very hard to get a sense of how good coverage is with gaps like this. I don't know if this is a shellspec or kcov issue.

Thank you for shellspec, I'm enjoying it immensely.

Unfortunately this is a kcov issue. You can measure coverage directly in kcov in the following way, but you will get the same results.

$ kcov ./cov ./test.sh

In the future I would like to eliminate the kcov dependency and replace it with own coverage tool shellcov, but this will not be done right away.

FYI: Coverage is generated from the following data internally. To fix this issue correctly, shell script parsing would be required.

$ cat -n test.sh
     1	#!/bin/bash
     2
     3	foo() {
     4	  var1="$1"
     5	  var2="$2"
     6	  date='{
     7	    "key": "value"
     8	  }'
     9	}
    10
    11	foo 1 2

$ PS4='$LINENO ' bash -x test.sh
11 foo 1 2
4 var1=1
5 var2=2
8 date='{
    "key": "value"
  }'

$ PS4='$LINENO ' ksh -x test.sh
11 foo 1 2
4 var1=1
5 var2=2
6 date=$'{\n    "key": "value"\n  }'

$ PS4='%I ' zsh -x test.sh
11 foo 1 2
4 var1=1
5 var2=2
6 date=$'{\n    "key": "value"\n  }'

Thank you for the detailed response. That makes a lot of sense. I'm looking forward to that.

BTW really liking shellspec. I wrote some DSL support for vim which I just published. It covers everything that I've run into so far: https://github.com/aareman/shellspec.vim
