Oops, looks like "Benedict Cumberbatch" just broke your unrealistic design specs and spotlights your non-inclusive cognitive bias, designer. Maybe stop using "John Smith" as mock design data for users' names and design things for real people.

Developers should not be paying down your design debts. Fix this!

Sincerely, the UI developer doing your job

How would you create a mock for an Aggregator Microservice (stateless) which makes requests to other services for each request, transforms the data and then responds to the user?
I want to create a mock service where I don't t have to run the other services but it should create kinda realistic responses.
Have you had to create something like this?
I'd use it for testing another microservice that uses the aggregator.
