You must name the setup and teardown functions of a file test fixture setupOnce and

teardownOnce, respectively. These functions take a single input argument, testCase,

into which the test framework automatically passes a function test case object. This test

case object contains a TestData structure that allows data to pass between setup, test,

and teardown functions. In this example, the TestData structure uses assigned fields to

store the original path, the temporary folder name, and the figure file name.

Create the setup and teardown functions as a local functions to axesPropertiesTest.

function setupOnce(testCase)

% create and change to temporary folder

testCase.TestData.origPath = pwd;

testCase.TestData.tmpFolder = ['tmpFolder' datestr(now,30)];

mkdir(testCase.TestData.tmpFolder)

cd(testCase.TestData.tmpFolder)

% create and save a figure

testCase.TestData.figName = 'tmpFig.fig';

aFig = createFigure;

saveas(aFig,testCase.TestData.figName,'fig')

close(aFig)

end

function teardownOnce(testCase)

delete(testCase.TestData.figName)

cd(testCase.TestData.origPath)

rmdir(testCase.TestData.tmpFolder)
