MATLAB Programming Fundamentals - MathWorks

The following steps show how to create specific tests. Put these tests inside the methods

block with the (Test) attribute.

Create Test Method for Real Solutions

Create a test method, testRealSolution, to verify that quadraticSolver returns the

right value for real solutions. For example, the equation has real

solutions and. This method calls quadraticSolver with the inputs of this

equation. The solution, expSolution, is [2,1].

Use the matlab.unittest.TestCase method, verifyEqual to compare the output of

the function, actSolution, to the desired output, expSolution. If the qualification

fails, the test continues execution.

function testRealSolution(testCase)

actSolution = quadraticSolver(1,-3,2);

expSolution = [2,1];

testCase.verifyEqual(actSolution,expSolution)

end

Add this function inside the methods (Test) block.

Create Test Method for Imaginary Solutions

Create a test to verify that quadraticSolver returns the right value for imaginary

solutions. For example, the equation has imaginary solutions

and. Add this function, testImaginarySolution, inside the

methods (Test) block.

function testImaginarySolution(testCase)

actSolution = quadraticSolver(1,2,10);
