How to: :clap: Doing It Right Example: The test highlights what is the cause of the test result
```javascript

test("When no credit, then the transfer is declined ", async() => {
      // Arrange
      const transferRequest = testHelpers.factorMoneyTransfer({userCredit:100, transferAmount:200}) //obviously there is lack of credit
      const transferServiceUnderTest = new TransferService({disallowOvercharge:true});

      // Act
      const transferResponse = await transferServiceUnderTest.transfer(transferRequest);

      // Assert
      expect(transferResponse.status).toBe(409); // Obviously if the user has no credit it should fail
    });
  ```
