Returning a Promise from "describe" is not supported. Tests must be defined synchronously

Question

Particular test passed but I am getting this.

    console.log node_modules/jest-jasmine2/build/jasmine/Env.js:502           ●   Test suite failed to run              Returning a Promise from "describe" is not supported. Tests must be defined synchronously.             Returning a value from "describe" will fail the test in a future version of Jest.          > 4 | describe('handlers.getSemesters', async () => { 

Here is complete test code

describe('handlers.getSemesters', async () => {       it('should return an array of Semesters', async () => {         academicCalendarRequest.request = jest.fn();         academicCalendarRequest.request.mockReturnValue([           {             description: 'Semester1',           }         ]);         const expected = [                 {             description: 'Semester1',           },         ];          const handlers = new Handlers();         const actual = await handlers.getSemesters();         expect(actual).toEqual(expected);       });     }); 

How can I fix it?

Answer 1

Change

describe('handlers.getSemesters', async () => { 

To

describe('handlers.getSemesters', () => { 

And then put asynchronous code inside of it block

it('should return an array of Semesters', async () => {   // ... })
