Fatally assert value is true
The value to test.

This method passes if and only if the actual value is a scalar logical with a value of true. Therefore, entities such as true valued arrays and nonzero doubles produce qualification failures when used in this method, despite these entities exhibiting "true-like" behavior such as triggering the execution of code inside of "if" statements.
This method is functionally equivalent to:
import matlab.unittest.constraints.IsTrue; fatalAssertable.fatalAssertThat(actual, IsTrue());
There exists more functionality when using the
However, this method is optimized for performance and does not
construct a new
IsTrue constraint for each call.
Sometimes such use can come at the expense of less diagnostic information.
fatalAssertReturnsTrue method for a similar
approach which may provide better diagnostic information.
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. Alternatively,
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
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
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
