Could this be a new method in Jest 18? We are currently shipping Jest 17.
An update with Jest 18 is coming within a few days.

Seems new in Jest 18. I can confirm it works on master and will work in [email protected] we're cutting very soon.

Awesome thanks @gaearon

Should be available on 0.9.0 we just released.

I'm getting this error with 0.9.3, even after nuking and reinstalling node_modules. Any ideas on what I'm missing?

[gaearon]

I can’t reproduce this. I added console.log(typeof expect.any) into src/App.test.js of a newly generated project, and it logs a function.

So if you still have issues, you’ll need to create a project reproducing this.

Figured it out. Somehow I ended up with react-scripts as a dependency as well as a devDependency, and when I upgraded from a previous version, only the devDependency upgraded. So I was actually using an older version of Jest, pre-expect.any. D'oh!

@dangerismycat you probably ran something like npm upgrade react-scripts --save-exact; anyway, glad you figured it out!
