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.
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.
`print` version of the logging functions supports `printf`-like
formatting, which we do not use and given our current debug print
internals, will never use. This should be slightly more efficient
and expresses the intent better.
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`.
Noticed that the code was originally concatenating strings just to
then append the result to another string. Now it does not create
temporaries and also preallocates the string buffer.
* 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.
This keeps it out of the main include path when benchmarking is
enabled, somewhat reducing the compilation-time penalty.
Also moved some other functions into the .cpp file, especially
helpers that could be given internal linkage, and concretized some
iterator-templated code that only ever used
`std::vector<double>::iterator`.
This allows us to move <stdexcept> out of the common path, and replace
it with just <exception>. The difference between these two headers is
~13k lines after preprocessing on libstdc++ (16k vs 3k) and ~17k lines
for MS's STL(33k vs 16k).
Note that this is only beneficial if no other stdlib header we use
includes <stdexcept>. AFAIK this is true for the newest MS's STL,
but I have no idea of the applicability for libstdc++ and libc++.
* 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)
Previously we had them to avoid including <algorithm> in the vector
matchers, but
* we included it anyway, even though we did not use it
* we use <algorithm> anyways in the generators
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 adds UNSCOPED_INFO macro, creating a log message that is stored
until the end of next assertion or the end of test case, whichever comes
first. These messages are not scoped locally, unlike messages created by
INFO macro.
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
7f229b4f caused the output file to get opened twice, while
some types of files (e.g. named pipes) can be only opened once.
After this change Session::applyCommandLine opens the output file
only when there is an error to print.
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.
The REQUIRE_THROWS and CATCH_REQUIRE_THROWS macros have
a subtle inconsistency in their implementation which can
cause a warning if [-Wunused-value] is used.
This commit changes CATCH_REQUIRE_THROWS so it has the
same implementation as REQUIRE_THROWS
It looks like REQUIRE_THROWS was change in commit
fae0fa4ec but not CATCH_REQUIRE_THROWS.
Similar changes for CATCH_CHECK_THROWS
The clock estimator has a potential division by zero.
Using `iteration + 1` seems also more logical to me for
an average.
Found with coverity in a downstream project.
The ostream passed as reference to `hexEscapeChar` is manipulated
and its original state not restored. This fixes it.

As explained in issue #1273, `operator&&` and `operator||` should give
a proper compile time error on use instead of the compiler complaining
about them not being defined. This commit adds an `always_false` type in
`catch_meta.hpp` used for implementing a nice `static_assert` for both
of the abovementioned operators.
Closes#1273
This doesn't cause trouble with GCC/Clang and libstdc++, but IAR
and its stdlib apparently doesn't compile when you use `fno-exceptions`
and `std::current_exception`/`std::rethrow_exception`.
Fixes#1462
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.
This is a temporarily workaround until we can nuke the current
verbosities system from the orbit and replace it with something
actually sane.
Fixes#1426
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*>.
simple code with provided main function which just returns 0
leaks memory due to fact that singletons are not cleaned up
running valgrind on such simple application reports that 752 bytes
are still available in 11 blocks
this commit adds destructor to Catch::LeakDetector which calls
Catch::cleanUp()
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
* Session::applyCommandLine overload on wchar_t
This allows users on Windows to use Catch::Session::applyCommandLine
with wchar_t * arguments of application.
With this change Session::run became templated so both char and wchar_t
version have the same implementation.
Xml result of reported will now contain value of rng-seed in case it
is not zero.
The value will be stored in element Randomness and it's attribute seed.

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.
This means
* Adding new configuration toggle `CATCH_CONFIG_DISABLE_EXCEPTIONS`
and a best-guess configuration auto-checking for it.
* Adding new set of internal macros, `CATCH_TRY`, `CATCH_CATCH_ALL`
and `CATCH_CATCH_ANON` that can be used in place of regular `try`,
`catch(...)` and `catch(T const&)` respectively, while disappearing
when `CATCH_CONFIG_DISABLE_EXCEPTIONS` is enabled.
* Replacing all uses of `throw` with calls to `Catch::throw_exception`
customization point.
* Providing a default implementation for the above customization point
when `CATCH_CONFIG_DISABLE_EXCEPTIONS` is set.
* Letting users override this implementation with their own.
* Some minor changes and ifdefs all around to support the above
issue #1360
It is possible to have multple given contexts in a single BDD scenario;
if you have to type 'and' in the GIVEN description; it's very likely you
need an AND.
A generic AND is not possible, thus a AND_GIVEN is added to complement
the AND_WHEN and AND_THEN.
Can be used without needing to increase indent:
SCENARIO("...") {
GIVEN("...")
AND_GIVEN("...") {
WHEN("...") {
THEN("...") {
// ...
}
}
}
}
would correctly output, when requested/needed:
Given: ...
And given: ...
When: ...
Then: ...
The padding had to be increased by a character in the output message, to
continue to be uniform.
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.

In case of 2 instances of SourceLineInfo constructed in the same
file, they will have the same `file` pointer (even at O0). Thus, we
can check if they are equal before calling potentially pointless
`strcmp`.
In theory the copy is cheap (couple of pointers change), but tests
are usually compiled in Debug mode/with minimal optimizations, which
means that most users will still have to pay the cost for those
function calls.
Because the macro name is compile-time constant, we do not have to
worry about lifetimes and will avoid allocation in case of missing
SSO or long macro name.
By opting the JUnit and XML reporters into it, we no longer run
into problem where they underreport the results without `-s` flag.

- seems the #ifdef was necessary after all, because of the difference in the way the cpp files are included in the full project vs the single include
- in the OC project I moved the #include of catch_tostring.cpp first. That solves the project for now, but is a brittle solution
