From what I found out in legal correspondence and deeds, it appears that “will” is used far more often than “testament“. Is one more formal than the other? If not, what is the difference between the two?
The full name of the document is Last Will and Testament. One definition:
A document in which a person specifies the method to be applied in the management and distribution of his estate after his death.
Will is a common term to refer to this document. I wouldn’t call it informal; I think it’s what people use most of the time. In a legal context you’re probably better off using the full name, though.
