Method Invocation

'pairwise' Methods are invoked for every pair of parameter values at

least once. While the test framework guarantees that tests are

created for every pair of values at least once, you should not

rely on that size, ordering, or specific set of test suite

elements.

For example, use the combined methods attribute TestMethodSetup,
ParameterCombination='sequential' to specify sequential combination of the
method setup-level parameters defined in the MethodSetupParameter properties block.

For this example, class setup-level parameterization defines the type of random number
generator. The method setup-level parameterization defines the seed for the random
number generator, and the test-level parameterization defines the data type and size of
the random number output.

Create TestRand Test Class

In a file in your working folder, create a class that inherits from
matlab.unittest.TestCase. This class tests various aspects of random number
generation.

classdef TestRand < matlab.unittest.TestCase

Define properties Blocks

Define the properties used for parameterized testing. Each properties block
corresponds to parameterization at a particular level.

properties (ClassSetupParameter)
generator = {'twister','combRecursive','multFibonacci'};
end

properties (MethodSetupParameter)
seed = {0, 123, 4294967295};
end

properties (TestParameter)
dim1 = struct('small', 1,'medium', 2, 'large', 3);
dim2 = struct('small', 2,'medium', 3, 'large', 4);
dim3 = struct('small', 3,'medium', 4, 'large', 5);
