Parameters:

info - contains information about the assertion.

actual - the given Throwable.

Throws:

AssertionError - if the actual Throwable is null.

AssertionError - if the actual Throwable has a cause.

Asserts that the message of the actual Throwable starts with the given description.

Parameters:

info - contains information about the assertion.

actual - the given Throwable.

description - the description expected to start the actual Throwable's message.

Throws:

AssertionError - if the actual Throwable is null.

Parameters:

info - contains information about the assertion.

actual - the given Throwable.

description - the description expected to be contained in the actual Throwable's message.

Throws:

AssertionError - if the actual Throwable is null.

AssertionError - if the message of the actual Throwable does not contain the given description.
