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
Instead, let it be installed as a dependency of `conan-package-tools`
to avoid trouble with the fact that pip is really bad at version
resolution, and that up-to-date version of the `conan` package is not
supported by up-to-date version of the `conan-package-tools` package.
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.
