macOS zsh: sourcing ./shunit2 throws an error: _shunit_fatal:1: command not found: echo -e

Hi Kate,

Just discovered your GIT repo. Great work! Until now I always tested shell scripts manually.
Trying to write few tests with your unit test framework.

Having a problem to run it on zsh shell though. I traced it down to ./shunit2 line 40-44.
when sourcing the the lib with ". ./shunit2" it throws an error: _shunit_fatal:1: command not found: echo -e

I am running on macOS BigSur 11.5.2, zsh version 5.8. Here are the details:
$ uname -mprsv
Darwin 20.6.0 Darwin Kernel Version 20.6.0: Wed Jun 23 00:26:31 PDT 2021; root:xnu-7195.141.2~5/RELEASE_X86_64 x86_64 i386

shell name: zsh
shell version: 5.8

--- Executing the 'sbxCommon' test suite ---
_shunit_fatal:1: command not found: echo -e

the bash and sh is running fine though

Can you provide some sample code that demonstrates the problem? Feel free to only share enough to demonstrate the issue.

Also, shUnit2 is tested using 'set -u' and 'set -e'. Are there other options set in your environment?

To note, this is what I get when running a quick test on my local machine running macOS Monterey 12.0.1.

OK

Obviously this isn't testing your setup…

Actually, this is the issue that can be fixed by setting the shwordsplit option for zsh, see here.
