Previously registration was case preserving, but lookup used
lowercased reporter name, so a reporter whose name contained
upper case character could not be requested by the user.
The base was also renamed from `TestEventListenerBase` to
`EventListenerBase`, and modified to derive directly from the
reporter interface, rather than deriving from `StreamingReporterBase`.
`SizeIs` can accept both `size_t` and a matcher. In the first case,
it checks whether the size of the range is equal to specified size.
In the second case, it checks whether the provided matcher accepts
the size of the range.
In general, for Catch2 v3 we are making virtual types `final`,
unless they were explicitly designed to be derived-from.
`ListeningReporter` is definitely not designed to be derived-from.
This commit also forbids composing lvalues of composed matchers, as
per previous deprecation notice. I do not expect this to be contentious
in practice, because there was a bug in that usage for years, and
nobody complained.
Now that the recommended distribution and usage method is proper
library, users can just avoid including the matcher headers to get
basically the same effect.
Users can still write a description for their sections, but it will
no longer be saved as part of the `SectionInfo` struct. This ability
has also been added to the documentation.
Closes#1319
This also required some refactoring of how the pattern matching
works. This means that the concepts of include and exclude patterns
are no longer unified, with exclusion patterns working as just
negation of an inclusion patterns (which led to including hidden
tags by default, as they did not match the exclusion), but rather
both include and exclude patterns are handled separately.
The new logic is that given a filter and a test case, the test
case must match _all_ include patterns and _no_ exclude patterns
to be included by the filter. Furthermore, if the test case is
hidden, then the filter must have at least one include pattern
for the test case to be used.
Closes#1184
Previously it returned the sum of listed things because ???. This
was completely useless and in many ways actively counterproductive
because of the success/failure conventions around exit codes.
Closes#1410
