IMO it's better to add #!/bin/sh to test.sh, chmod +x it and then add ./test.sh as a script because it's sh compatible and there is no need for bash per se.

[nickmessing]

Just as option, maybe it's worth considering replacing sh with shelljs just like vue?

[aladdin-add]

@nickmessing up to this. I encountered some questions when running test on windows 10. #748 (comment)

[nickmessing]

@aladdin-add, that is fixed by using shelljs which is cross-platform

[LinusBorg]

@nickmessing is this good to merge for you?

[nickmessing]

@LinusBorg, yes, I use only linux based operating systems but this solution will not work on windows. As long as nobody who works on this template uses windows it's fine but if there is requirement to support windows I'd highly recommend rewriting test.sh in .js with shelljs.

So it's your call, do you want to support windows or unix is okay? 😉

[aladdin-add]

ready to merge. 🚀
👍 to replace sh to shelljs, we can finish it in another PR. (I created a new issue #895)

[LinusBorg]

Leave have a look at #1218. I took a bit more ambitious approach to improve the testing story for the template.
