In this task you need to imagine that you — yes, YOU — have developed a problem on Cody for me to solve, and now you need to develop a Test Suite to check whether my submitted solutions meet your requirements or not.So the tables are turned! You are now in the role of Tester! I am in the role of Player!The problem you've set me is to:<ul><li>output the sine of an angle, when the angle is specified in degrees as a (scalar) <a href = "https://au.mathworks.com/help/matlab/ref/double.html"><tt>double</tt></a>, with no restriction in the domain.</li></ul>You provide me with the following example for the function defined as <tt>s = SINE(a)</tt>:<pre> % INPUT
 a = 45 % degrees
 % OUTPUT
 s = 1/sqrt(2)</pre>Now I have responded by submitting a large number of purported 'solutions', some of which are reasonably accurate, and others which are either too imprecise or else logically flawed.Your Test Suite (contained within your function <tt>testSuite</tt>) must address each of the elements of your problem specification:<ol><li>Check that my submitted code reliably returns sufficiently accurate values for sine of many different angles. Use the <a href = "https://au.mathworks.com/help/matlab/ref/assert.html"><tt>assert</tt></a> function.</li><li>Ensure that the returned data type is suitable.</li><li>You cannot use (or mention) the functions <tt>sind</tt>, <tt>sin</tt>, <tt>cscd</tt> or <tt>cosd</tt> in your Test Suite; any other functions are allowed. [ MOTIVATION: You shouldn't be exposing an efficient way of solving the problem within your Test Suite, otherwise I can just copy and paste your solution and submit it as my own! ]</li><li>Your <tt>assert</tt> (or other) function must throw <a href = "https://www.mathworks.com/matlabcentral/cody/problems/44357">errors/exceptions</a> with the following <tt>error message</tt> text contents.</li></ol><ul><li>'Incorrect value' if the output is too inaccurate.</li><li>'Incorrect data type' if the output is not appropriate.</li></ul>When creating a Test Suite for a Cody problem it is a good habit to try to anticipate the tactics that diverse Players might employ!See also:<ul><li><a href = "https://www.mathworks.com/matlabcentral/cody/problems/44631">Problem 44631</a> (part 0)</li><li><a href = "https://www.mathworks.com/matlabcentral/cody/problems/44617">Problem 44617</a> (part 1)</li><li><a href = "https://www.mathworks.com/matlabcentral/cody/problems/44521">Problem 44521</a> (part 3)</li></ul>
