The parameter given to `convert` may not be copyable therefore it has to be
captured by const reference. For example an `std::tuple` that contains a
non-copyable type is itself non-copyable.
The NonDefaultConstructible test-case was reduced by one example type
because it did not add any value.
They lead to stringification of file (which is ok) and file line
(not ok) to the approvals, which makes them exceedingly brittle
and not worth approval testing. Instead we just run them as part
of the base test run.
This PR ultimately does 3 things
* Separately tracks matched tests per each filter part (that is, a set of filters separated by an OR (`,`)), which allows Catch2 to report each of the alternative filters that don't match any tests.
* Fixes `-w NoTests` to return non-zero in the process
* Adds tests for `-w NoTests`.
* Fix non-default-constructible type lists used in TEMPLATE_LIST_TEST_CASE
std::tuple is not default constructible when the first type is not
default-constuctible. Therefore it can not be instantiated.
to circumvent this, we have to use std::declval in the unevaluate decltype
context.
* Units from <ratio> are no longer redeclared in our own namespace
* The default clock is `steady_clock`, not `high_resolution_clock`,
because, as HH says "high_resolution_clock is useless. If you want
measure the passing of time, use steady_clock. If you want user
friendly time, use system_clock".
* Benchmarking support is opt-in, not opt-out, to avoid the large
(~10%) compile time penalty.
* Benchmarking-related options in CLI are always present, to decrease
the amount of code that is only compiled conditionally and making
the whole shebang more maintainble.
Changes done to Nonius:
* Moved things into "Catch::Benchmark" namespace
* Benchmarks were integrated with `TEST_CASE`/`SECTION`/`GENERATE` macros
* Removed Nonius's parameters for benchmarks, Generators should be used instead
* Added relevant methods to the reporter interface (default-implemented, to avoid
breaking existing 3rd party reporters)
* Async processing is guarded with `_REENTRANT` macro for GCC/Clang, used by default
on MSVC
* Added a macro `CATCH_CONFIG_DISABLE_BENCHMARKING` that removes all traces of
benchmarking from Catch
This fixes an issue where a self-assignment of a StringRef copy would point into internally (and now dangling) data.
(now self-assignment check is no longer needed)
Eventually this needs to be fixed in the textflow project by Phil,
but he has not done so in the half a year this bug has been known
to be there, so...
Closes#1470Closes#1455
* Deduce map return type implicitly
Giving the first template argument to map generator function to deduce
return type is now optional even if the return type is different from
the type generated by mapped generator.
This avoids the problem where writes to stderr/stdout stop being
line-buffered when stderr/stdout is redirected to a file, which led
to different order of outputs between Linux and Windows in our tests.
This generator collects values from the underlying generator until it
has a specified amount of them, and then returns them in one "chunk".
In case the underlying generator does not have enough elements for
a specific chunk, the left-over elements are discarded.
Closes#1538
Previously, for a TEMPLATE_PRODUCT_TEST_CASE("Test" ..., T, (P1, P2)),
the generated test case names were
Test - 0
Test - 1
With this commit, the correct typename is used:
Test - T<P1>
Test - T<P2>

MSVC needs another indirection to evaluate INTERNAL_CATCH_STRINGIZE
and also inserts a space before theINTERNAL_CATCH_STRINGIZE_WITHOUT_PARENS
parameter, which we can get rid of by pointer arithmetic.
By using non-trivially copyable types, we force libstdc++-9's variant to
properly enter the valueless-by-exception state for our stringification
test.
Related to #1511
support for generating test cases based on multiple template template
types combined with template arguments for each of the template template
types specified
e.g.
```
TEMPLATE_PRODUCT_TEST_CASE("template product","[template]",
(std::tuple, std::pair, std::map),
((int,float),(char,double),(int,char)))
```
will effectively create 9 test cases with types:
std::tuple<int,float>
std::tuple<char,double>
std::tuple<int,char>
std::pair<int,float>
std::pair<char, double>
std::pair<int,char>
std::map<int,float>
std::map<char,double>
std::map<int,char>
Tested type is accessible in test case body as TestType
Unique name is created by appending ` - <index>` to test name
since preprocessor has some limitations in recursions
Closes#1454
The previous implemetation was just plain broken for most of
possible uses, the new one should work (even though it is ugly
as all hell, and should be improved ASAP).
Fixes#1436
This adds support for templated tests and test methods via
`TEMPLATE_TEST_CASE` and `TEMPLATE_TEST_CASE_METHOD` macros. These
work mostly just like their regular counterparts*, but take an
unlimited** number of types as their last arguments.
* Unlike the plain `TEST_CASE*` macros, the `TEMPLATE*` variants
require a tag string.
** In practice there is limit of about 300 types.
No matcher actually uses it, and there is no good reason for it,
as the best it can do for user is removing a single indirection
when using the pointer inside the matcher. Given the overhead of
other code that will be running during such time, it is completely
meaningless.
This also fixes compilation for PredicateMatcher<const char*>.
This fixes 3 problems:
* Relative paths on Windows are now supported
* Out-of-tree (paths starting with ../) builds are now supported
* Path separator normalization no longer affects non-path components of input (problem with Compact reporter)

By default, it expands into a `static_assert` + `SUCCEED` pair, but
it can also be deferred to runtime by defining
`CATCH_CONFIG_RUNTIME_STATIC_REQUIRE`, which causes it to expand
into plain old `REQUIRE`.
Closes#1362Closes#1356
Previously a mismatched prefix would be skipped before the actual
comparison would be performed. Obviously, it is supposed to be
_matching_ prefix that is skipped.
The StringMaker is off by default and can be enabled by a new macro `CATCH_CONFIG_ENABLE_VARIANT_STRINGMAKER`, to avoid increasing the footprint of stringification machinery by default.
The support is to be considered experimental, that is, the interfaces,
the first party generators and helper functions can change or be removed
at any point in time.

Happening when using clang and templated operators, clang cannot decide
between the operator provided by ReusableStringStream and the one provided
by the value value as both are templates. This is easily solved by calling
the operator<< through the member syntax.
Fixes#1285
This support is based on overriden `std::exception::what` method, so
if an exception does not do so meaningfully, the message is still
pointless.
This is only used as a fallback, both `StringMaker` specialization and
`operator<<` overload have priority..
