Alternate UserNameEnvironmentVariableFixture Class Definition

classdef UserNameEnvironmentVariableFixture < ...

matlab.unittest.fixtures.Fixture

properties (Access=private)

OriginalUser

end

properties (SetAccess=private)

UserName

end

methods

function fixture = UserNameEnvironmentVariableFixture(name)

validateattributes(name, {'char'}, {'row'}, '','UserName')

fixture.UserName = name;

fixture.SetupDescription = sprintf( ...

'Set the UserName environment variable to "%s".',...

fixture.UserName);

end

function setup(fixture)

fixture.OriginalUser = getenv('UserName');

fixture.assertNotEmpty(fixture.OriginalUser, ...

'An existing UserName environment variable must be defined.')

setenv('UserName', fixture.UserName)

end

function teardown(fixture)

fixture.TeardownDescription = sprintf(...

'Restored the UserName environment variable to "%s".',...

fixture.OriginalUser);

setenv('UserName', fixture.OriginalUser)

end

end

methods (Access=protected)

function bool = isCompatible(fixture, other)

bool = strcmp(fixture.UserName, other.UserName);

end

end

end

The setup method does not contain a call to addTeardown or a definition for

TeardownDescription. These tasks are relegated to the teardown method. The

alternative class definition contains an additional property, OriginalUser, which allows

the information to be passed between methods.
