MATLAB Programming Fundamentals - MathWorks

To explore the properties of this app prior to testing, create an instance of the app at the

command prompt.

app = ConfigurePlotAppExample;

This step is not necessary for the tests, but it is helpful to explore the properties used by

the app tests. For example, use app.UpdatePlotButton to access the Update Plot

button within the app object.

Create a test class that inherits from matlab.uitest.TestCase.

classdef testConfigurePlotAppExample < matlab.uitest.TestCase

methods (Test)

end

end

Create a test method test_SampleSize to test the sample size. The test method

modifies the sample size, updates the plot, and verifies that the surface uses the specified

sample size. The call to addTeardown deletes the app after the test is complete.

classdef testConfigurePlotAppExample < matlab.uitest.TestCase

methods (Test)

function test_SampleSize(testCase)

app = ConfigurePlotAppExample;

testCase.addTeardown(@delete,app);

testCase.type(app.SampleSizeEditField,12);

testCase.press(app.UpdatePlotButton);

ax = app.UIAxes;

surfaceObj = ax.Children;

testCase.verifySize(surfaceObj.ZData,[12 12]);

end

end

end

Create a second test method test_Colormap to test the colormap. The test method

selects a colormap, updates the plot, and verifies that the plot uses the specified

colormap. The full code is now as follows.
