This ended up being a surprisingly large refactoring, motivated
by removing a `const_cast` from `Config`'s handling of reporter
streams, forced by previous commit.
This way it makes much more sense from logically-const point
of view, and also means that concrete implementations don't
have to always have a `mutable` keyword on the stream member.
This means that the CLI interface now uses the new key-value oriented
reporter spec, the common reporter base creates the colour implementation
based on the reporter-specific configuration, and it also stores the
custom configuration options for each reporter instance.
Closes#339 as it allows per-reporter forcing of ansi colour codes.
The new reporter spec generalizes key-value options that can be
passed to the reporter, looking like this
`reporterName[::key=value]*`. A key can be either Catch2-recognized,
which currently means either `out` or `colour`, or reporter-specific
which is anything prefixed with `X`, e.g. `Xfoo`.
Test case hashing includes tags and class name
As the hasher involves more code now, it was split out into its own file
and it got its own set of tests.
Closes#2304
This includes always compiling the ANSI and None colour
implementations, as they don't need to touch any platform
specific APIs, and removing their respective compile-time
configuration options.
Because the Win32 colour implementation requires Win32-specific
APIs, it is still hidden behind a compile-time toggle,
`CATCH_CONFIG_COLOUR_WIN32` (renamed from `..._COLOUR_WINDOWS`).
The commandline options for colours were also changed. The
option now uses different name, and allows to select between
different implementations, rather than changing whether
the compiled-in colour implementation is used through
"yes/no/default" options.
This also required splitting out Listener factory from
the reporter factory hierarchy. In return, the listener
factories only need to take in `IConfig const*`, which
opens up further refactorings down the road in the colour
selection and implementation.
- do not hardcode content of containers
- prefix members with m_
- add const and non-const iterators to `with_mocked_iterator_access`
- remove `m_touched` as it wasn't filled properly and isn't used anyway
This opens path to per-reporter colour output customization,
and fixes multiple issues with the old colour implementation.
Under the old implementation, using Win32-backed colouring
would always change the colour used by the console, even if the
actual output was written elsewhere, such as a file passed by
the `--out` flag. This will no longer happen, as the reporter's
colour impl will check that the reporter's stream is pointed
to console before trying to change the colours.
POSIX/ANSI colour implementation suffered a similar-ish issue,
in that it only wrote the colour escape codes into the default
output stream, even if the reporter asking for colouring was
actually writing to a completely different output stream.
This will become useful when reworking colour support, because
Win32 colour support requires checking whether the output is
stdout, which is done through the `IStream` wrapper.
Removed:
* NaN normalization
* INFINITY normalization
* errno normalization
* Completely unused duration regex
Tests using these macros should be tagged `[approvals]`
so they are not run as part of approval tests.
Also simplified regex for the test's executable filename,
and hidden some tests relying on nullptr normalization.
This avoids issues with Catch2's handler firing too early, on
structured exceptions that would be handled later. This issue
meant that the old attempts at structured exception handling
were incompatible with Windows's ASan, because it throws
continuable `C0000005` exception, which it then handles.
With the new handling, Catch2 is only notified if nothing else,
including the debugger, has handled the exception.

This requires a bunch of different changes across the reporter
subsystem.
* We need to handle multiple reporters and their differing
preferences in `ListeningReporter`, e.g. what to do when
we mix reporters that capture and don't capture stdout.
* We need to change how the reporter is given output and
how we parse reporter's output destination from CLI.
* Approval tests need to handle multireporter option
By not materializing the lower cased tags ahead of time, we
save allocations at the cost of worsened performance when comparing
two tags.
Since there are rarely many tags, and commonly they are not
compared even if present, this is almost always a win. The new
implementation also improves the robustness of the code
responsible for handling tags in a case-insensitive manner.
A new flag, `--allow-running-no-tests` was added to override this
behaviour if exit code of 0 was desired.
This change also made `-w NoTests` obsolete, and so it has been
removed.
Previously a lambda parser in Clara could only be invoked once,
even if it internally was ok with being invoked multiple times.
With this change, a lambda parser can mark itself as `accept_many`,
in which case it will be invoked multiple times if the appropriate
flag was supplied multiple times by the user.
This greatly simplifies running Catch2 tests in single binary
in parallel from external test runners. Instead of having to
shard the tests by tags/test names, an external test runner
can now just ask for test shard 2 (out of X), and execute that
in single process, without having to know what tests are actually
in the shard.
Note that sharding also applies to test listing, and happens after
tests were ordered according to the `--order` feature.
The problem came from the console reporter trying to provide a
fancy linebreaking (primarily for things like `SCENARIO` or the
BDD macros), so that new lines start with extra indentation if
the text being line broken starts as "{text}: ".
The console reporter did not properly take into account cases
where the ": " part would already be in a later line, in which
case it would ask for non-sensical level of indentation (larger
than single line length).
We fixed this by also enforcing that the special indentation case
only triggers if the ": " is found early enough in the line, so
that we also avoid degenerate cases like this:
```
blablabla: F
a
n
c
y
.
.
.
```

* Apply PR #2297 to devel branch
It turns out that Issue #2272 partially affected the devel branch. When
building tests with C++20, the compiler emits a warning that top-level
comma expressions in array subscripts are depricated. Warnings are
treated as errors, so this caused the build to fail.
This commit adds localized warning suppression
in accordance with this recommendation here:

* Fixed unknown pragma warning on old versions of gcc & clang
This commit fixes an unkwown pragma warning on older versions of GCC
and Clang. These older versions don't have a warning for depricated use
of the comma subscript. Because warning suppression is localized, and
only refers to the comma subscript warning, it doesn't affect compiler
warnings in other parts of the code.

The problem with the old name was that it collided with the
range matcher `Contains`, and it was not really possible to
disambiguate them just with argument types.
Closes#2131
This change also changes it so that test case macros using a
class name can have same name **and** tags as long as the
used class name differs.

This event listener performs basic consistency checks (akin to
matching braces) on events that are passed to the listeners
when the `SelfTest` test binary is run.
The current checks are about nesting events (e.g. `testCaseStarting`
cannot be received before `testRunStarting`, `sectionStarting`
can only be received when a test case is active, etc), and matching
up counts of starting/ended events.
The simplicity means that it could be confused by starting/ended
events matching up but being out of order, e.g.
```
* test case A starting
* test case B ended
* test case B starting
* test case A ended
```
would be accepted, even though it is wrong. However, doing full
order checking would be much more implementation work, for relatively
little benefit, so it is left out for now.
With these changes, all these benchmarks
```cpp
BENCHMARK("Empty benchmark") {};
BENCHMARK("Throwing benchmark") {
throw "just a plain literal, bleh";
};
BENCHMARK("Asserting benchmark") {
REQUIRE(1 == 2);
};
BENCHMARK("FAIL'd benchmark") {
FAIL("This benchmark only fails, nothing else");
};
```
report the respective failure and mark the outer `TEST_CASE` as
failed. Previously, the first two would not fail the `TEST_CASE`,
and the latter two would break xml reporter's formatting, because
`benchmarkFailed`, `benchmarkEnded` etc would not be be called
properly in failure cases.
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
More specifically, made the actual implementation of string-like
type handling take argument as `Catch::StringRef`, instead of
taking `std::string const&`.
This means that string-like types that are not `std::string` no
longer need to pay for an extra construction of `std::string`
(including the potential allocation), before they can be stringified.
The actual string stringification routine is now also better about
reserving sufficient space.
This test tends to be brittle on Mac CI machines, which are
heavily loaded and bursty. Since the tests are only run as part
of the "extra tests" test set, this increase should not have
a significant impact on the total duration of CI runs.
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.

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
The base was also renamed from `TestEventListenerBase` to
`EventListenerBase`, and modified to derive directly from the
reporter interface, rather than deriving from `StreamingReporterBase`.
