BOOST_TEST
: details on expressionsOnce a test case has been declared, the body of this test should be written. A test case is a sequence of operations in which assertions are inserted. Those assertions evaluate statements that implement the expectation being validated, and report failures and/or information in a uniform manner, depending on the log level.
The Unit Test Framework's supplies a toolbox of assertions
to ease the creation and maintenance of test cases and provide a uniform error
reporting mechanism. The toolbox supplied is in most part in a form of macro
declarations. An (almost) unique interface to all of them implemented by the
macro BOOST_TEST
.
