I want to know the answer to the following question:
What are 'friendlies' for charity usually called in the UK?
All the background I'm provided with is that "A one-off match for charitable fundraising, usually involving one or two all-star teams, or a match held in honor of a player for contribution to his/her club, may also be described as exhibition matches but they are normally referred to as charity matches and testimonial matches respectively.". Is that enough to answer the question?
Answer: yes
