- [section:obsolete_init_func The obsolete initialization function]
- For backwards compatibility, the __UTF__ also allows the customization of an initialization function of a different type.
- This is called the ['obsolete initialization function]. Its signature is:
- ```
- boost::unit_test::test_suite* init_unit_test_suite(int argc, char* argv[]);
- ```
- The original design of the __UTF__ required of the programmer to implement it. It was intended to initialize and return
- the __master_test_suite__. No [link ref_BOOST_AUTO_TEST_CASE automatic test case registration] was available at that
- time. The null-pointer value was considered an initialization error.
- In the header-only usage variant, you fall back to the obsolete initialization function signature by omitting the
- definition of macro __BOOST_TEST_ALTERNATIVE_INIT_API__ in test module code.
- [bt_example custom_obsolete_init..using obsolete initialization function..run-fail]
- In the static-library usage variant, you need to omit the definition of macro __BOOST_TEST_ALTERNATIVE_INIT_API__ in test
- module and compile the __UTF__ static library without the compilation flag __BOOST_TEST_ALTERNATIVE_INIT_API__ (this is
- the default).
- In the shared-library usage variant, it is not possible to use the obsolete initialization function.
- Even if you decide to us the obsolete initialization function, it is recommended that:
- # You always return a null-pointer value and install the master test suite via
- [memberref boost::unit_test::test_suite::add `test_suite::add`] as illustrated
- [link ref_BOOST_TEST_CASE here]. The current framework does no longer treat the
- null-pointer value as failure.
- # You signal the failure by throwing [classref boost::unit_test::framework::setup_error] exception.
- # You access the command-line arguments through the interface of the __master_test_suite__,
- and ignore the function's arguments `argc` and `argv`.
- [caution The obsolete initialization function is deprecated as its name indicates. It is recommended to migrate
- to the new API, and rely on the automated test unit registration and [link boost_test.tests_organization.fixtures
- fixtures] (including [link boost_test.tests_organization.fixtures.global global fixtures]) for other set-up. ]
