Create Optional Fixture Functions

Setup and teardown code, also referred to as test fixture functions, set up the pretest

state of the system and return it to the original state after running the test. There are two

types of these functions: file fixture functions that run once per test file, and fresh fixture

functions that run before and after each local test function. These functions are not

required to generate tests. In general, it is preferable to use fresh fixtures over file

fixtures to increase unit test encapsulation.

A function test case object, testCase, must be the only input to file fixture and fresh

fixture functions. The Unit Test Framework automatically generates this object. The

TestCase object is a means to pass information between setup functions, test functions,

and teardown functions. Its TestData property is, by default, a struct, which allows

easy addition of fields and data. Typical uses for this test data include paths and graphics

handles. For an example using the TestData property, see “Write Test Using Setup and

Teardown Functions” on page 33-35.

File Fixture Functions

Use file fixture functions to share setup and teardown functions across all the tests in a

file. The names for the file fixture functions must be setupOnce and teardownOnce,

respectively. These functions execute a single time for each file. You can use file fixtures

to set a path before testing, and then reset it to the original path after testing. This is a

typical example of skeletal file fixture setup and teardown code.

function setupOnce(testCase) % do not change function name

% set a new path, for example

end

function teardownOnce(testCase) % do not change function name

% change back to original path, for example

end
