This also introduces Catch::clog() method to allow embedded targets
to override std::clog usage with their own stream (presumably null-sink),
similarly to how Catch::cout() and Catch::cerr() are used.
Fixes#989
This is not thread safe, but I think that was already true of Catch.
The construction/destruction of the std::ostringstream is where the
vast majority of time is spent per assertion. A simple test of
100000000 CHECK()s is reduced from around 60s to 7.4s
By using char const * instead of std::string we avoid significant
copying per assertion. In a simple loop with 10000000 CHECKS on
my system, this reduces the run time from 9.8s to 6s.
This prevents Catch from disabling `Wpadded` for Clang inside test files
(files that do not define either `CATCH_CONFIG_MAIN` or
`CATCH_CONFIG_RUNNER`).
catch_suppress_warnings.h and catch_reenable_warnings.h should be
included only once*, so that the stitching script includes them as the
first and last header respectively, since it only includes each header
once. This caused a bug, where the first one was included properly, but
the second one was included prematurely, from catch_xmlwriter.hpp, and
thus was guarded by `CATCH_IMPL`.
* At least until the stitching script is changed to accomodate common
warning disabling header.
Fixes#871
Types which are truthy, but have more information than the truthiness in their string conversion were showing up as 'true' or 'false' instead of showing the underlying type's string value.
Previously, this would not print out any messages for the last CHECK
```cpp
TEST_CASE("Foo") {
INFO("Test case start");
for (int i = 0; i < 2; ++i) {
INFO("The number is " << i);
CHECK(i == 0);
}
CHECK(false);
}
```
now it does.
- typedefs long long for MSVC
- typedefs uint64_t otherwise
Should probably do finer grained compiler checking - but this should at least be better than what was there before
When using C++11, comparison operators are already templated to take
anything that can be explicitly converted to double, but constructor
took only doubles. This lead to warnings when an `Approx` was
constructed from floats, which was problematic for some users.
Since just adding float constructor would be a large breaking change, as
suddenly `Approx( 1 )` would become ambiguous, I added a templated
constructor that will take anything that is explicitly convertible to
double. This has the added benefit of allowing constructing `Approx`
instances from instances of strong typedefs, ie allowing
`calculated_temp == Approx( known_temp)`.
Closes#873
