11 Console16bit.prototype = Object.create ( GameConsole.prototype) ;

A developer has the following array of student test grades:

Let arr = [ 7, 8, 5, 8, 9 ];

The Teacher wants to double each score and then see an array of the students

who scored more than 15 points.

How should the developer implement the request?

A test has a dependency on database.query. During the test the dependency is replaced

with an object called database with the method, query, that returns an array. The

developer needs to verify how many times the method was called and the arguments

used each time.

Which two test approaches describe the requirement?
