How can I assert against an object where some values are dynamic?

THE BEST ONE. Love it. metricValue: expect.any(Number),

metricValue: 23 <- will pass

BEST combo right here. Works well with floats too.

matchObject({
  num: expect.any(Number),
});

Other options...

expect({test: 1, test2: 2, test3: 3}).toMatchObject({test:1}); This will pass

More complex example...

const firstEmitCall = obs.emit.mock?.calls[0];

// need to assemble assertions like this to avoid asserting on the dynamic timing values (will be different on CI)
// assert on each of the 3 args passed to obs.emit()

expect(firstEmitCall[0]).toEqual("cpl_timer_testing-timer-end");
expect(firstEmitCall[1]).toEqual("info");
expect(firstEmitCall[2]).toMatchObject(expectedEmitPayload);
