At some point we moved over to catch2:catchorg (notice lowercase `c`)
instead of Catch2:catchorg, but we kept uploading the released
packages to the upper-cased repository... Time to fix this, and then
merge them again.
The naming scheme is simple, to include all matchers, include header
`catch2/matchers/catch_matchers_all.hpp`. To include **everything**,
include `catch2/catch_all.hpp`.
This describes the reality better, as it also links in the rest
of Catch2.
The on-disk name of the static library remains just `Catch2Main`,
as that is what it is -- single main function -- and on-disk artifacts
cannot describe link dependencies.
It is no longer used by v3, and contains obsolete versions of the
headers anyway. There are future plans for some sort of replacement,
but those are,
1) in the future
2) different than the single header model
so we can delete the folder completely.
Originally the tests were from #1912, but as it turned out, the issue
was somewhere else. Still, the inputs provided were interesting, so
they are now part of our test suite.
Catch assumes std::uncaught_exceptions is available whenever C++17 is
available, but for macOS versions older than 10.12 this is not the case.
Instead of checking the C++ version, use a macro to check whether the
feature is available.
Previously a random test ordering was obtained by applying std::shuffle
to the tests in declaration order. This has two problems:
- It depends on the declaration order, so the order in which the tests
will be run will be platform-specific.
- When trying to debug accidental inter-test dependencies, it is helpful
to be able to find a minimal subset of tests which exhibits the issue.
However, any change to the set of tests being run will completely
change the test ordering, making it difficult or impossible to reduce
the set of tests being run in any reasonably efficient manner.
Therefore, change the randomization approach to resolve both these
issues.
Generate a random value based on the user-provided RNG seed. Convert
every test case to an integer by hashing a combination of that value
with the test name. Sort the test cases by this integer.
The test names and RNG are platform-independent, so this should be
consistent across platforms. Also, removing one test does not change
the integer value associated with the remaining tests, so they remain in
the same order.
To hash, use the FNV-1a hash, except with the basis being our randomly
selected value rather than the fixed basis set in the algorithm. Cannot
use std::hash, because it is important that the result be
platform-independent.
It did not clear out all of its internal state when switching from
one pattern to another, so when it should've escaped `,`, it took
its position from its position in the original user-provided string,
rather than its position in the current pattern.
Fixes#1905
CATCH_INTERNAL_IGNORE_BUT_WARN() introduced with b7b346c triggers
clang-tidy warning 'cppcoreguidelines-pro-type-vararg' for every usage
of assertion macros like CHECK() and REQUIRE(). Silence it via NOLINT
in the '#if defined(__clang__)' block only, as clang-tidy honors those.
The old code caused warnings to fire under MSVC, and Clang <3.8.
I could not find a GCC version where it worked, but I assume that it
did at some point.
This new code causes all of MSVC, GCC, Clang, in current versions,
to emit signed/unsigned comparison warning in test like this:
```cpp
TEST_CASE() {
int32_t i = -1;
uint32_t j = 1;
REQUIRE(i != j);
}
```
Where previously only MSVC would emit the warning.
Fixes#1880
