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.
They now take `StringRef` as the argument, and are virtual only
in the basic interface.
Also cleaned out the various reporters and their overrides
of these members which were often empty or delegating up.
This means that e.g. for `TEST_CASE` with two sibling `SECTION`s
the event will fire twice, because the `TEST_CASE` will be entered
twice.
Closes#2107 (the event mentioned there already exists, but this
is its counterpart that we also want to provide to users)
This means that it can no longer be safely made ahead of time,
but nothing in our existing code used it like that. Normally it
is constructed and used in the same expression, which is now
more efficient.
Using the `CATCH_MOVE` and `CATCH_FORWARD` macros instead of the
`std::move` and `std::forward<T>` utility functions can improve
compilation times and debug build's performance, and thus will
be preferred going forward.
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.
