Schedule a function to be run the next time the clock is advanced by any ammount.
Schedule a function to be run when the clock advances each multiple
of n past the current point.
If multiple steps are advanced at once, for example doing
c.setInterval(fn, 1) ; c.advance(1000), then it will only call the
function once. This allows you to simulate clock jitter.
Only ms granularity.
Schedule a function to be run when the clock has advanced n ms beyond
the current point.
Only ms granularity.
Advance the clock by n ms. Use floats for smaller increments of time.
Clear an immediate timer created by the clock. (alias for Clock#clearTimeout)
Clear an interval created by the clock. (alias for Clock#clearTimeout)
Mocks all the things in the global space.
Returns exit function, for ease of doing t.teardown(c.enter()).
If entered, exit the clock, restoring the global state
Advance the clock in steps, awaiting a Promise at each step, so that actual asynchronous events can occur, as well as timers.
Mock of process.hrtime(), returning [seconds, nanoseconds] on the
clock.
Mock of process.hrtime.bigint(), returning BigInt representation of
current nanosecond time.
Returns the current ms time on the clock.
The promisified setImmediate, also available via
promisify(clock.setImmediate)
Optionalvalue: undefinedOptionaloptions: { reffed?: boolean; signal?: AbortSignal }promisified setInterval, also available via
promisify(clock.setImmediate)
Optionaln: numberOptionalvalue: undefinedOptionaloptions: { reffed?: boolean; signal?: AbortSignal }The promisified setTimeout, also available via
promisify(clock.setTimeout)
Optionaln: numberOptionalvalue: undefinedOptionaloptions: { reffed?: boolean; signal?: AbortSignal }Set the clock to a specific time. Will fire timers that you zoom past.
