Using the default counter and checking the current requests count:

const inflightRequests = require('inflight-requests');

assert(inflight.requestsCount() === 0);

Passing a context to record the inflightRequests property:

const inflightRequests = require('inflight-requests');

app.use(inflightRequests(app.locals));
assert(app.locals.inflightRequests === 0);
