@mnaumanali94 I was having trouble fixing the commit message issues so I reopened a new PR instead. Sorry for the confusion. I've addressed the lint issues, but I'm having trouble getting all tests to work as well as adding appropriate tests of my own. Would love some help if you have time as I haven't worked with test-harness before and can't seem to get them to run locally in dev-container.

@rudfoss-rr So to run harness tests you first need to build the binaries. For that cd into the package/cli folder and run yarn build.binary and then at the root level run yarn test.harness. Let us know if you run into issues!

Thanks! I've updated tests and attempted to add a few scenarios of my own, but was unable to completely rebuild the scenario tests using either test.harness, build or build.binary so I wasn't able to properly verify all scenarios locally. I'm guessing there is just some script I'm missing.

I now see that I've broken a few other tests, but I'm not sure exactly why. If you could have a look and point me in the right direction that would be great!
