Class: matlab.unittest.qualifications.Assertable
Package: matlab.unittest.qualifications
Assert string matches specified regular expression
assertMatches(assertable,actual,expression)
assertMatches(assertable,actual,expression,diagnostic)
assertMatches( asserts
that assertable,actual,expression)actual is a string scalar or character
vector that matches the regular expression defined by expression.
assertMatches( also displays the diagnostic information in assertable,actual,expression,diagnostic)diagnostic upon
a failure.

This method is functionally equivalent to:
import matlab.unittest.constraints.Matches; assertable.assertThat(actual, Matches(expression));
There exists more functionality when using the Matches constraint
directly via assertThat.
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. 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 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.
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.
