On systems where std::chrono::steady_clock::period is not std::nano, benchmark tests fail to compile due to trying to convert analysis.samples from a vector of duration<double, clock::period> to a vector of std::chrono::duration<double, std::nano>.
Previously, each warning suppression was self-contained, with its
own pair of `SUPPRESS_X_WARNING` and `UNSUPPRESS_X_WARNING` macros.
This had the obvious advantage of being self-containing, but it
also meant that if we needed to suppress more than one warning
in a single place, then we would manipulate the compiler's warning
state multiple times, even though logically we would only need one
layer.
The new way of suppressing warnings in macros is to push compiler's
warning state with `CATCH_INTERNAL_START_WARNINGS_SUPPRESSION` macro,
then disable whatever macros we need with the
`CATCH_INTERNAL_SUPPRESS_X_WARNINGS` macro, and then return to the
previous state using `CATCH_INTERNAL_STOP_WARNINGS_SUPPRESSION`.
The JUnit report is improved in that:
* The message shows the testing condition, not the result
* The actual message has similar output than the console one
Now it no longer tries to be this weird hybrid between an owning
and non-owning reference, and is only ever non-owning. This is also
reflected in its interface, for example `StringRef::isNullTerminated`
is now public, and `StringRef::c_str()` has the precondition that it
is true.
Overview of the changes:
* The `StringRef::m_data` member has been completely removed, as it
had no more uses.
* `StringRef::isSubstring()` has been made public and renamed to
`StringRef::isNullTerminated()`, so that the name reflects what the
method actually does.
* `StringRef::currentData()` has been renamed to `StringRef::data()`,
to be in line with common C++ containers and container-alikes.
* `StringRef::c_str()` will no longer silently make copies. It instead
has a precondition that `isNullTerminated()` is true.
* If the user needs a null-terminated string, they should use the
`std::string` conversion operator and call `c_str()` on the resulting
`std::string`.
* Some small optimizations in various places.
* Basic functionality is now `constexpr`.
This should now properly handle small numbers which would previously
output something like `[0.00000000000000019, 0.00000000000000019]`,
which does not allow user to read the numbers properly.
Closes#1760
this warning was introduced by rework to support NTTPs
since we have implementation macro for NTTPs and normal template test cases
warning is going to be suppressed
Fixes#1762
Only works for exceptions that publicly derive from `std::exception`
and the matching is done exactly, including case and whitespace.

It checks Knuth's _close enough with tolerance_ relationship, that
is `|lhs - rhs| <= epsilon * max(|lhs|, |rhs|)`, rather then the
_very close with tolerance_ relationship that can be written down as
`|lhs - rhs| <= epsilon * min(|lhs|, |rhs|)`.
This is because it is the more common model around the internet, and
as such is likely to be less surprising to the users. In the future
we might want to provide the other model as well.
Closes#1746
This means that if you nest multiple random generators inside one
test case, they will not return the same sequence of numbers.
Idea taken from #1736 by Amit Herman.
Closes#1736Closes#1734
In the future, we will also want to introduce our own
`uniform_int_distribution` and `uniform_real_distribution` to get
repeatable test runs across different platforms.
Wrong nesting of namespaces resulted in the `Catch` namespace
being ambigous between `::Catch` and `::{anon}::Catch` namespaces.
This should fix it.
Closes#1761
It was used in checking that types in TEMPLATE_TEST_CASE and friends
were unique, but this was removed for v2.8.0 (#1628). Since there
are no further uses of this trait, the simplest thing to do is to
just remove it.
Fixes#1757
The leading/trailing whitespace is problematic because of e.g.
`WHEN` macro having preceeding whitespace for alignment, and it is
generally messy.
Credits to Phil who did lot of the original work.
Closes#1708
This way it is explicit when there is a `StringRef` -> `std::string`
conversion and makes it easier to look for allocations that could
be avoided.
Doing this has already removed one allocation per registered test
case, as there was a completely pointless `StringRef` -> `std::string`
conversion when parsing tags of a test case.
The old code was a left-over from the times when the
`capturedExpression` member was a `const char*`, which could always
be indexed. With the change to use `StringRef`, blindly indexing 0th
element is invalid, as it is not indexable part of a StringRef.
