Answer 1

I had the same issue, and as Cody mentioned, by increasing the "testTimeout" in my Jest config file, I managed to overcome this error.

Hope this helps other people encountering this error, thank you very much

My config file:

{
  "moduleFileExtensions": ["js", "json", "ts"],
  "rootDir": ".",
  "testEnvironment": "node",
  "testRegex": ".e2e-spec.ts$",
  "transform": {
    "^.+\\.(t|j)s$": "ts-jest"
  },
  "verbose": true,
  "testTimeout": 1000000
}

The timeout is referring to the the test taking longer than 5000 ms.

You can set the test timeout programmatically although I don't think this can be done within a test (as you've shown above) it would need to be done in a global setup file like jest.setup.js

Alternateively, I would suggest setting the timeout in your jest.config.js

example:

{
  "name": "my-project",
  "jest": {
    "verbose": true,
    "testTimeout": 5000
  }
}
