Assumption failures produce filtered tests. In the matlab.unittest.TestResult class,

such a test is marked Incomplete.

Since filtering test content through the use of assumptions does not produce test failures,

it has the possibility of creating dead test code. Avoiding this requires monitoring of

filtered tests.

Test Methods

If an assumption failure is encountered inside of a TestCase method with the Test

attribute, the entire method is marked as filtered, but MATLAB runs the subsequent Test

methods.

The following class contains an assumption failure in one of the methods in the Test

block.

classdef ExampleTest < matlab.unittest.TestCase

methods(Test)

function testA(testCase)

testCase.verifyTrue(true)

end

function testB(testCase)

testCase.assumeEqual(0,1)

% remaining test code is not exercised

end

function testC(testCase)

testCase.verifyFalse(true)

end

end

end

Since the testB method contains an assumption failure, when you run the test, the

testing framework filters that test and marks it as incomplete. After the assumption
