💬 suggestion: ‏add a comment to explain why you need this

[BenoitZugmeyer]

🥜 nitpick: ‏ ‏it could be simpler to pass the configuration object to getExpiredState

[BenoitZugmeyer]

💬 suggestion: ‏I don't think the anonymous id value is tested in this test. Maybe remove this line?

[BenoitZugmeyer]

💬 suggestion: ‏

Suggested change

	const EXPIRED_SESSION: SessionState = { isExpired: '1', anonymousId: '0' }
	const EXPIRED_SESSION: SessionState = { isExpired: '1', anonymousId: jasmine.any(String) as string }

[BenoitZugmeyer]

💬 suggestion: ‏remove this line, use jasmine.any(String)
