Inform Johnny-Five that it must not create a repl instance if deployed to flash...

[rwaldron]

By setting:

this.repl = false;

In the Tessel constructor (before emitting "ready"), we can inform Johnny-Five that it must not create a repl instance.

The criteria is:

• If the cwd starts with /app/remote-script/

I took a couple of stabs at this, and am at an interesting spot:

First, I was looking at process.cwd() but it turns out, that doesn't return what I'd expect.

• Under t2 run index.js: /root
• Under t2 push index.js: /

Then, I switched to __dirname instead, which generally provides what I'd expect:

• Under t2 run index.js: /tmp/remote-script
• Under t2 push index.js: /app/remote-script

Under my current detection, under run the REPL will still be available (though in practice, I'm finding that it's not really usable), but under push it turns off, and I've verified this via my t2-rgb-led-rainbow repo as linked above.

However, I'm finding that authoring tests in this environment is difficult, as __dirname is per-module, so I can't easily mock it in any reasonable fashion.

• I can't just set __dirname since it's local to the test module
• If I set global.__dirname it still doesn't work, since __dirname appears to be a local variable

Still trying other things, but wanted to document steps thus far.

[rwaldron]

Make a function that returns __dirname and expose that function in the test environment, the you can stub that instead
