It's my first time building proper selenium tests (I've touched on IDE before). I'm using Selenium with NodeJS, WebdriverIO, Mocha framework, wdio-spec-reporter and wdio-browserstack-service.
I have managed to create my tests, suites specified in conf.js , hooked into browserstack (so when i run in command line, it creates a text log and video in browserstack).
Now I've been asked to do something so that when a test/suite is run it will automatically save the text logs as a text file. 

My thoughts are either building an additional function and hooking into the spec reporter or retrieving them from browserstack. I've spent a bit of time googling it, but apart from using the allure reporter (looks like it can do this?), I am struggling to find any information. Is this possible? If so, how & which way?

Thanks for your help
