How to set different timeout dynamically for every test suite?

[gladykov]

Hi,

We are running multiple test suites in parallel, with delayed execution meaning A.test.ts and B.test.ts will start together, and A.test.ts will execute step immediately, but B.test.ts will sleep() 30 seconds, before executing steps (this is how you test cloud apps, in env you don't have control over, which does not like bots).

So timeout for test suite A is 60 seconds, and for test suite B is 60 + 30 seconds. We have many test suites, so we calculate timeout dynamically.

We are in a process of migrating from Jest to Vitest 🤡 and we used to use this jest.setTimeout() to dynamically set timeout inside test suite.

helper.ts

export function getDelayPerFile(testPath: string) {
   // calculations
	return seconds: Number;
}

A.test.ts

import {...}

 jest.setTimeout(200000 + getDelayPerFile(testPath) * 1000);

beforeAll(async () => {
    await sleepWithoutCount(getDelayPerFile(expect.getState().testPath) * 1000);
(...)

But now things start to get tricky:

1. I didn't find such method to set timeout dynamically for Vitest
2. I guess getting file path is not possible outside of Vitest methods. Fine with me as we can still use beforeAll(ctx)

So any ideas for solution here, which would allow us manipulate timeout for every single test suite? I think actually we need to manipulate hookTimeout , since wait will happen inside beforeAll. Once tests will run, it will run normally, without delay.

Did you check https://vitest.dev/api/vi.html#vi-setconfig?

This might work:

-  jest.setTimeout(200000 + getDelayPerFile(testPath) * 1000);
+  vi.setConfig({ testTimeout: 200000 + getDelayPerFile(testPath) * 1000 });

Makes sense! Will test and report back 🙂
