Running TASER with a mocha test suite

Hi TASER team!
I read your paper, really cool! I'm interested in trying to replicate running TASER with a mocha test suite (or some other javascript test suite as mentioned in the paper).

My current setup works just fine for the example.js shipped in this repo, but when I try to run it with a simple javascript project having nothing other than an empty test:

describe('Missing assertions', function() {
    it('cloneDeep directly from require', function() {

    })
})

And running it instrumenting the mocha executable which lives normally under node_modules/mocha/bin/mocha, with the following:

TASER_ROOT="..."
POLICY_FILE="$TASER_ROOT/src/DefaultPolicy.js" \
POLICY_OUT="model.json" \
LIBRARY_UNDER_TEST="lodash" \
bash -c "$TASER_ROOT/instrumented-node/node node_modules/mocha/bin/mocha"

I keep getting the following error:

Marked sink RegExp
Marked sink match
Marked sink search
Successfully loaded policy: /Users/thepalbi/Facultad/tesis/workspace/taser/src/DefaultPolicy.js
Successfully setup the analysis
`

  Missing assertions
    ✓ cloneDeep directly from require

I'm guessing my stacktrace doesn't help much, but wanted to ask if there was something special you did when running TASER alongside with javascript test suites? Almost certain that error occurs because of the instrumented NodeJS vm running the tests framework.
