Cake O'Clock Project - Unit Testing

I am rather confused as to why I’m encountering the error here, when I have used the video walkthrough as a guide throughout the project to ensure I was doing it right!

The code below is supposedly the error, due to an ‘unexpected string’ (apologies I’m not able to format this in code)

And below, is a screenshot of the code that I’m required to put in for that appropriate step. Worth noting that at the final stage of the project (where I got to), the walkthrough video had compiled, whereas mine hadn’t, but I had completed it in exactly the same way.

Thank you,
