The assertions are grouped into classes and each class contains a set of methods for the assertions. The assertions are named in a way that makes them easy to read and understand. For example, assertThat() is the method that is used to start an assertion. The next part of the assertion is the object to be tested, and the last part is the method that performs the assertion.
