Define Test Class and Test Method Setup Methods

Define the setup methods at the test class and test method level. These methods register

the initial random number generator state. After the framework runs the tests, the

methods restore the original state. The ClassSetup method defines the type of random

number generator, and the TestMethodSetup seeds the generator.

methods (TestClassSetup)

function ClassSetup(testCase, generator)

orig = rng;

testCase.addTeardown(@rng, orig)

rng(0, generator)

end

end

methods (TestMethodSetup)

function MethodSetup(testCase, seed)

orig = rng;

testCase.addTeardown(@rng, orig)

rng(seed)

end

end

Define Sequential Parameterized Test Methods

Define a methods block with the Test and ParameterCombination='sequential'

attributes. The test framework invokes these methods once for each corresponding

property value.

methods (Test, ParameterCombination='sequential')

function testSize(testCase,dim1,dim2,dim3)

testCase.verifySize(rand(dim1,dim2,dim3),[dim1 dim2 dim3])

end

end

The method tests the size of the output for each corresponding parameter in dim1, dim2,

and dim3. For example, to test all the 'medium' values use:

testCase.verifySize(rand(2,3,4),[2 3 4]);. For a given TestClassSetup and

TestMethodSetup parameterization, the framework calls the testSize method three

times—once each for the 'small', 'medium', and 'large' values.
