test.jest.setTimerTickMode

config: { mode: 'manual' | 'nextAsync' } | { delta: number; mode: 'interval' }
): typeof jest;

Choose how the fake clock moves when the test doesn't move it.

  • manual: it doesn't move. This is the default.
  • nextAsync: each turn of the real event loop runs the next timer.
  • interval: it advances by delta milliseconds (default 20) every delta real milliseconds.
