Proof is the action and effect of testing (take an exam or experiment on the qualities of someone or something). The tests, therefore, are the essays that are made to know how something will turn out in its final form, or the arguments and means that seek to prove the truth or falsity of something.

The tests are signs, signs or indications of something : "A hair found at the crime scene was the proof that allowed us to discover the identity of the murderer", "Pereira affirms that he is in a position to exercise his position efficiently, although he has to give proof of this".
A test can also be a evaluation or an exam that is done for someone to demonstrate their knowledge and skills about a certain matter : “My son got an eight in the science test”, “I have to give the driving test to renew my license”, "This weekend I will not be able to leave: on Monday I have chemistry test and I need to study to pass".
