How to fix the ‘Jest did not exit one second after the test run has completed’ error with TypeScript?
To fix the ‘Jest did not exit one second after the test run has completed’ error with TypeScript, we should make sure we clean up when our test is done.
For instance, we write
beforeAll((done) => {
done();
});
//...
afterAll((done) => {
mongoose.connection.close();
done();
});
to call done after calling mongoose.connection.close(); to close the MongoDB connection after our test is done.
Then Jest knows that the test is done and ends the test.
Conclusion
To fix the ‘Jest did not exit one second after the test run has completed’ error with TypeScript, we should make sure we clean up when our test is done.
