Class: matlab.unittest.qualifications.Assumable
Package: matlab.unittest.qualifications
Assume value is not equal to specified value
assumeNotEqual(assumable,actual,notExpected)
assumeNotEqual(assumable,actual,notExpected,diagnostic)
assumeNotEqual( assumes
that assumable,actual,notExpected)actual is not equal to notExpected.
assumeNotEqual( also displays the diagnostic information in assumable,actual,notExpected,diagnostic)diagnostic upon
a failure.

Diagnostic information related to the qualification, specified as one of the following:
Diagnostic values can be nonscalar. For more information, see |

and replace calls to verifyNotEqual with assumeNotEqual.
This method is functionally equivalent to:
import matlab.unittest.constraints.IsEqualTo; assumable.assumeThat(actual, ~IsEqualTo(notExpected));
There exists more functionality when using the IsEqualTo constraint
directly via assumeThat.
Use assumption qualifications to ensure that the test environment
meets preconditions that otherwise do not result in a test failure.
Assumption failures result in filtered tests, and the testing framework
marks the tests as Incomplete. Alternatively,
Use verification qualifications to produce and record failures without throwing an exception. Since verifications do not throw exceptions, all test content runs to completion even when verification failures occur. Typically verifications are the primary qualification for a unit test since they typically do not require an early exit from the test. Use other qualification types to test for violation of preconditions or incorrect test setup. For more information, see matlab.unittest.qualifications.Verifiable.
Use assertion qualifications when the failure condition
invalidates the remainder of the current test content, but does not
prevent proper execution of subsequent test methods. A failure at
the assertion point renders the current test method as failed and
incomplete. For more information, see matlab.unittest.qualifications.Assertable.
Use fatal assertion qualifications to abort the test
session upon failure. These qualifications are useful when the failure
mode is so fundamental that there is no point in continuing testing.
These qualifications are also useful when fixture teardown does not
restore the MATLAB® state correctly and it is preferable to abort
testing and start a fresh session. For more information, see matlab.unittest.qualifications.FatalAssertable.
