How do I throw a new Error with Object containing Error details in typeScript?
I am using jest for testing typescript code and I want to throw new Error as shown below:
mock.spyOn(AppUtils,'util_plane').mockImplementation(() => {
throw new Error("Error Message",{status:403})
})
when I do this, the compiler complains saying:
Expected 0-1 arguments, but got 2.ts(2554)
Error constructor doesn't expect {status: number} to be passed to it. You can create and use custom error class:
class CustomError extends Error {
status: number;
constructor(message: string, { status }: { status: number }) {
super(message);
this.status = status
}
}
// ...
throw new CustomError('Error Message', { status: 403 })
Or you could assign status property to the error after creation:
throw Object.assign(new Error('Error Message'), { status: 403 })
