Many modules' utests currently don't support enabling all
tests at once. Furthermore, some modules' tests are complex,
for example due to their numerous dependencies on other
modules. This makes it nearly impossible to enable all
tests with a single global switch. Consequently, the
previously defined `RT_UTEST_USING_ALL_CASES` has lost
its original meaning.
We recommend deprecating this configuration switch. If a
module needs to enable a group of functional tests through
its own configuration, this local enable all switch should
be implemented by the module itself, and a global RTT enable
switch will no longer be provided.
If such a requirement arises in the future, we recommend
careful design, especially considering how to ensure that
turning on a single switch enables all dependencies for
all involved modules for ease of use.
