Provide dependency globally?

[PatrikBird]

Hey guys! I started playing around with Vitest and I really like it so far, thanks for creating such an amazing tool!

I'm currently migrating a Project that uses msal-browser for authentication.
This dependency relies on crypto APIs which are not available while running the tests, hence I need to provide them.

Using Jest, I could do this globally as shown here.

Is there an equivalent in Vitest to this? Or should I use the globalSetup?

Cheers! Patrik

Don't think globalSetup will work, since it is run in the main thread, and not in tests
You can just import crypto in setupFiles and assign it to globalThis:

import crypto from 'crypto'
globalThis.crypto = crypto

thanks for your quick response. I’ll test this tonight

@sheremet-va Thank you 🙏🏻
This worked for a similar issue I was having! lifesaver.

Sorry for my late reply. With

globalThis.crypto = crypto

in my setupFile.ts, I'm getting the following type error:
Type 'typeof import("crypto")' is missing the following properties from type 'Crypto': subtle, getRandomValuests(2739)

If I just ignore it, the tests still fail with the same crypto_nonexistent error as before.

Edit: I don't expect to get the solution served on a silver platter. Just FYI 😄

It worked with

globalThis.window.crypto = crypto;

Just the type error remains, which is no biggie. Thank you!

Add the following using setupFiles:

import crypto from 'crypto'
globalThis.window.crypto = crypto;
