I have a slight nitpick with the error message, but otherwise this LGTM.
'CallExpression': function(node) { | ||
const name = node.callee.name; | ||
if (isTimer(name) && node.arguments.length < 2) { | ||
context.report(node, `${name} must have exactly 2 arguments`); |

This error message seems a bit misleading to me, since setTimeout
and setInterval
can be called with more than 2 arguments. Maybe it would be better to use must have at least 2 arguments
instead.

Yes, you are right, I updated the rule to accommodate more arguments but did not update the message. Fixed.
module.exports = function(context) { | ||
return { | ||
'CallExpression': function(node) { | ||
const name = node.callee.name; |

I'm not sure if it matters, but name
will be undefined
for calls like foo.bar()
.

I think that's fine but would be happy to add a check for the situation if others feel differently.
I think this is unnecessary and we should probably not bother. |
Unless these are specifically testing |

There are several places in the code base where setTimeout() or setInterval() are called with just a callback and no duration/interval. The timers module will use a value of `1` in that situation. I find an unspecified duration or interval confusing. I always spend a moment wondering if it is a mistake. Did the original author simply forget to provide a value? Did they intend to use setImmediate() or even process.nextTick() instead of setTimeout()? And so on. This change provides a duration or interval of `1` to all calls in the codebase where it is missing. `parallel/test-timers.js` still tests the situation where `setTimeout()` and `setInterval()` are called with `undefined` and other non-numeric values for the duration/interval.
Add a custom ESLint rule to require that setTimeout() and setInterval() get called with at least two arguments. This prevents omitting the duration or interval.
