This is a simplification of the fix proposed in #2152, with the
critical function split out so that it can be tested directly,
without having to go through the ULP matcher.
Closes#2152
This includes
* Testing both positive and negative path through the matchers
* Testing them with types whose `begin` and `end` member functions
require ADL
* Testing them with types that return different types from `begin`
and `end`
The old name was a legacy of v2 era, where all headers were stitched
into one. With v3 using separate headers, it is better when they have
proper name.
The problem was that under specific circumstances, namely that none
of their children progressed, `GeneratorTracker` will not progress.
This was changed recently, to allow for code like this, where a
`SECTION` follows a `GENERATE` at the same level:
```cpp
SECTION("A") {}
auto a = GENERATE(1, 2);
SECTION("B") {}
```
However, this interacted badly with `SECTION` filters (`-c foo`),
as they could deactivate all `SECTION`s below a generator, and thus
stop it from progressing forever. This commit makes GeneratorTracker
check whether there are any filters active, and if they are, it checks
whether its section-children can ever run.
Fixes#2025
Most of the changes are completely pointless renaming of constructor
arguments so that they do not use the same name as the type members,
but 🤷Closes#2015
* Added some missing `noexcept`s on custom destructors.
* Fixed `std::move` being called on a const-reference.
* Initialized `ScopedMessage::m_moved` in class definition, instead
of doing so in constructors explicitly.
* Turned some `enum`s into `enum class`es.
* Initialized `StreamingReporterBase::currentTestCaseInfo` in class
definition.
* Some cleanups in SelfTest code.
* Successive executions of the same `GENERATE` macro (e.g. because
of a for loop) no longer lead to multiple nested generators.
* The same line can now contain multiple `GENERATE` macros without
issues.
Fixes#1913
Doing some benchmarking with ClangBuildAnalyzer suggests that
compiling Catch2's `SelfTest` spends 10% of the time instantiating
`std::unique_ptr` for some interface types required for registering
and running tests.
The lesser compilation overhead of `Catch::Detail::unique_ptr` should
significantly reduce that time.
The compiled implementation was also changed to use the custom impl,
to avoid having to convert between using `std::unique_ptr` and
`Catch::Detail::unique_ptr`. This will likely also improve the compile
times of the implementation, but that is less important than improving
compilation times of the user's TUs with tests.
As far as I know, only a few users actually use it, but these changes
allow us to avoid including a surprising amount of code in the main
compilation path.
The old code caused warnings to fire under MSVC, and Clang <3.8.
I could not find a GCC version where it worked, but I assume that it
did at some point.
This new code causes all of MSVC, GCC, Clang, in current versions,
to emit signed/unsigned comparison warning in test like this:
```cpp
TEST_CASE() {
int32_t i = -1;
uint32_t j = 1;
REQUIRE(i != j);
}
```
Where previously only MSVC would emit the warning.
Fixes#1880
These files are not included by the default
`#include <catch2/catch_test_macros.hpp>` path, so that users do
not have to pay for them if they do not use them. Follow up is to
split out the small part of `catch_preprocessor.hpp` used by the
default test macros (AFAIK, it is just `INTERNAL_CATCH_REMOVE_PARENS`
macro), so that it is not included by the default path either.
Also fixes#1892 by providing the missing macros.
This is both a really big and a really small commit. It is small in
that it only contains renaming, moving and modification of include
directives caused by this.
It is really big in the obvious way of touching something like 200
files.
The new rules for naming files is simple: headers use the `.hpp`
extension. The rules for physical file layout is still kinda in
progress, but the basics are also simple:
* Significant parts of functionality get their own subfolder
* Benchmarking is in `catch2/benchmark`
* Matchers are in `catch2/matchers`
* Generators are in `catch2/generators`
* Reporters are in `catch2/reporters`
* Baseline testing facilities are in `catch2/`
* Various top level folders also contain `internal` subfolder,
with files that users probably do not want to include directly,
at least not until they have to write something like their own
reporter.
* The exact files in these subfolders is likely to change later
on
Note that while some includes were cleaned up in this commit, it
is only the low hanging fruit and further cleanup using automatic
tooling will happen later.
Also note that various include guards, copyright notices and file
headers will also be standardized later, rather than in this commit.
This was an old "include all" header, that we no longer want to be
usable, to make the include differences in new versions explicit.
We will introduce new "include all" headers later, in the form of
`catch_all.hpp`, `catch_matchers_all.hpp` and so on...
The two changes are
`catch_matchers_templates` -> `catch_matchers_templated` and
`catch_matchers_generic` -> `catch_matchers_predicate`. The former
is mostly cosmetic, but the second was previously significantly
misleading, and as the library is now to be consumed by including
specific headers, this needed to be fixed.
`SizeIs` can accept both `size_t` and a matcher. In the first case,
it checks whether the size of the range is equal to specified size.
In the second case, it checks whether the provided matcher accepts
the size of the range.
In the future we can expect many more matchers, so let's give them
a place to live.
Also moved matcher-related internal files to `internal` subfolder.
Ideally we should sort out all of our source code, but that will
have to come later.
This commit also forbids composing lvalues of composed matchers, as
per previous deprecation notice. I do not expect this to be contentious
in practice, because there was a bug in that usage for years, and
nobody complained.
Given that in the 2 or so years that matchers are thing nobody complained,
it seems that people do not actually write this sort of code, and the
possibility will be removed in v3. However, to avoid correctness bugs,
we will have to support this weird code in v2.
- Overrides added
- usages of push_back() replaced with emplace_back()
- Loop variable made const-refernce
- NULL replaced with nullptr
- Names used in the declaration and definition unified
- size() replaced with empty
- Identical cases merged
This commit extends the Matchers feature with the ability to have type-independent (e.g. templated) matchers. This is done by adding a new base type that Matchers can extend, `MatcherGenericBase`, and overloads of operators `!`, `&&` and `||` that handle matchers extending `MatcherGenericBase` in a special manner.
These new matchers can also take their arguments as values and non-const references.

Now that Catch2 is a proper library, we can always build the full
library (comparatively minor slowdown) and the user can avoid
including benchmarking headers to avoid the compilation slowdown.
Now that the recommended distribution and usage method is proper
library, users can just avoid including the matcher headers to get
basically the same effect.
