Is there a way to mock a class from a route using Jest in TypeScript? I came across the "when" method in the mockito framework, but I'm wondering if Jest has something similar for this purpose.

Unfortunately, there is no default feature within jest that achieves this specific functionality. However, you can achieve a similar outcome using alternative methods:
const spy = jest
.spyOn(myObject, 'do')
.mockImplementation((someNumber) => someNumber > 1 ? true : false)
const = jest
.spyOn(myObject, 'do')
.mockReturnValue(true)
.mockReturnValueOnce(false)
.mockReturnValueOnce(true);
