I have class Person constructor(state, uid). State can only have two values "active" and "inactive". this is how setState function looks like
setState(value) {
if (value === "active" || "inactive") {
this._state = value
} else {
throw new Error("error")
}
}
and Jest is throwing error
Error: expect(received).toThrow()
Received function did not throw
this is the line where error occurs
expect(() => p1.setState("bla")).toThrow();
How can I rewrite setState function, so that Jest registers the error.
You made an error in the if statement expression. This is how it should be:
if (value === 'active' || value === 'inactive') {
In your code, the right side of the or operator is a string constant, which will always evaluate to true.
