I'm getting the error Unexpected token var for this code when running with -c flag:

In file test.js:

// require('lab') and other code deleted for clarity

In file fail.js

'use strict';
var actions=[1,2,3]
var rm={}
for (var action of actions) {
    rm[action] = true

If declaration of action is moved outside the for-loop it works

var action
for (action of actions) {

Looks like && node.parent.type !== 'ForOfStatement' needs to be added to to get:

if (trackedTypes.indexOf(node.type) !== -1 &&
    (node.type !== 'VariableDeclaration' || (node.parent.type !== 'ForStatement' && node.parent.type !== 'ForInStatement' && node.parent.type !== 'ForOfStatement')) &&
    (node.type !== 'ExpressionStatement' || node.expression.value !== 'use strict') &&
    node.parent.type !== 'LabeledStatement') {

    node.set('global.__$$labCov._line(\'' + filename + '\',' + node.loc.start.line + ');' + node.source());

Found in lab version 6.2.0

…e for-of

I got numbers in test/coverage.js (percent, sloc & hits) by first adding
another for-in loop into partial.js below the existing one:
    for (var o in j) {

When the test worked and 100% code coverage was achieved, the loop was
changed to for (var o of j)

This occurs when this is true:
node.type == "VariableDeclaration"
node.parent.type == "ForOfStatement"
