I am writing unit test cases and I have sequelize.transaction in my function. How to I mock the sequelize.transaction function.
My function looks like
create = async (req: Request) => {
await sequelize.transaction(async (t) => {
// Lock Test Balance Row
const testBalance = await this.testBalanceDAL.findByTestTypeAndUserIdForUpdate(
testTypeId,
userId,
t
);.....`
const sequelize = require('sequelize');
jest.mock('sequelize', () => ({
transaction: jest.fn(() => Promise.resolve()),
}));
describe('...', () => {
it('should ...', () => {
sequelize.transaction.mockImplementation(() => { ... });
expect(sequelize.transaction).toBeCalled();
});
});
