The new scheme is that there is one protected member instance of
`ReporterPreferences` in the `IStreamingReporter` base class,
and derived classes can modify it to express their own preferences.
Retrieving the preferences is now a non-virtual operation, which
makes it much cheaper to read them frequently. Previously, we
avoided doing so by caching the preferences in another variable,
but we still read them at least once per test case run.
`catch_reporter_bases.hpp` turned out fairly expensive for parsing
when building the main library, and the significant amount of code
in headers likely doesn't help. Since the reason it is in the header
is legacy from CRTP reporter bases, moving as much of the
implementations to the .cpp file is free compilation perf.
With CMake 3.18.0 the `add_test(NAME)` handling changed. The escaped
double quotes confuse the new call. Work around this upstream change.

TAP format requires all results to be reported.
Removed extraneous preferences function (handled by parent)
Incorporated fix from 3d9e7db2e0
Simplified total printing
This means that code such as
```cpp
TEST_CASE() {
SECTION("first") { SUCCEED(); }
auto _ = GENERATE(1, 2);
SECTION("second") { SUCCEED(); }
}
```
will run and report 3 assertions, 1 from section "first" and 2
from section "second". This also applies for greater and potentially
more confusing nesting, but fundamentally it is up to the user to
avoid overly complex and confusing nestings, just as with `SECTION`s.
The old behaviour of `GENERATE` as first thing in a `TEST_CASE`,
`GENERATE` not followed by a `SECTION`, etc etc should be unchanged.
Closes#1938
A test runner already has a --durations option to print durations.
However, this isn't entirely satisfactory.
When there are many tests, this produces output spam which makes it hard
to find the test failure output. Nevertheless, it is helpful to be
informed of tests which are unusually slow.
Therefore, introduce a new option --min-duration that causes all
durations above a certain threshold to be printed. This allows slow
tests to be visible without mentioning every test.
There are some examples on issue #850 of using this feature, but they
are not easily found from the documentation. Adding them here as an
example makes them more findable and ensures they keep working if the
API changes.
Some notes on the configuration options chosen:
* We want `AllowShortEnumsOnASingleLine` set to `false`, but that
option is clang-format-11 and up, which is not out yet.
* `IndentPPDirectives` is currently inconsistent, but `AfterHash`
is the preferred style in new code.
* `NamespaceIndentation` is a mess, but `All` is closer to the effect
we want than `Inner`.
* `SpacesInParentheses` set to `true` is not ideal due to it also
introducing extra spaces in preprocessor expressions, but using it
is much closer to the current style than not.
All in all, using this setting globally would reformat pretty much
every line of code in the codebase, but it is as close as possible
to the bespoke style currently used. Still, it should only be used
on the diffs.
Closes#1182
On systems where the file system has excute permissions, this script was
not marked as executable in a clean git checkout and so could be run
without first changing the permissions. Fixed by setting the relevant
git flag.
Some compilers, e.g. the Green Hills C++ compiler, react badly to the
appearance of std::exception_ptr, std::current_exception,
std::rethrow_exception and std::uncaught_exception(s). To allow usage of
Catch2 with these compilers when exceptions are disabled, hide the usage
of std::exception_ptr etc. when compiling with
CATCH_CONFIG_DISABLE_EXCEPTIONS.
* Successive executions of the same `GENERATE` macro (e.g. because
of a for loop) no longer lead to multiple nested generators.
* The same line can now contain multiple `GENERATE` macros without
issues.
Fixes#1913
This brings our output inline with GTest's. We do not handle skipped
tests properly, but that should be currently less important than
having the attribute exist with proper value for non-skipped tests.
Thanks @joda-01.
Closes#1899
The issue is caused by deleted `std::__detail::begin` declared in `bits/iterator_concepts.h`. This would be found by ADL, and because it is deleted, compilation would fail. This change makes it so that we SFINAE on `begin(std::declval<T>())` and `end(std::declval<T>())` being well-formed.

D:\vcpkg\toolsrc\include\catch2\catch.hpp(11288): warning C6330: 'char' passed as _Param_(1) when 'unsigned char' is required in call to 'isspace'.
ISO/IEC 9899:2011:
"7.4 Character handling <ctype.h>"/1
[...] In all cases the argument is an int, the value of which shall be
representable as an unsigned char or shall equal the value of the macro
EOF. If the argument has any other value, the behavior is undefined.
This means if isspace was passed a character like ñ it could corrupt
memory without the static_cast to treat it as a positive value after
integral promotion (and C libraries commonly use the int index supplied
as a key into a table which result in out of bounds access if the
resulting int is negative).
Ideally, clang-tidy would be smart that if one alias of a warning
is suppressed, then the other one is suppressed as well, but as of
right now, it isn't. This means that for now we have to suppress
both aliases of this warning. Opened upstream issue to fix this:
https://bugs.llvm.org/show_bug.cgi?id=45859
Obviously, ideally clang-tidy would also not warn that we are calling
a vararg function when it is an unevaluated magic builtin, but that
also is not happening right now and I opened an issue for it:
