cannot test controller methods

[xiaomaitai]

Hello, I got the error when trying to test controller methods with jest. It seems "electron_1.ipcMain" is undefined.
Is this my bug or this lib does not support jest? Could you please help me out? Thanks you.

Test suite failed to run

TypeError: Cannot read properties of undefined (reading 'handle')

Solved by mock electron "handle" function.
