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
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 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
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
.
.
.
```
Fixes#2309
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 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 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`
This means that code such as
```cpp
TEST_CASE() {
SECTION("first") { SUCCEED(); }
auto _ = GENERATE(1, 2);
SECTION("second") { SUCCEED(); }
}
```
will run and report 3 assertions, 1 from section "first" and 2
from section "second". This also applies for greater and potentially
more confusing nesting, but fundamentally it is up to the user to
avoid overly complex and confusing nestings, just as with `SECTION`s.
The old behaviour of `GENERATE` as first thing in a `TEST_CASE`,
`GENERATE` not followed by a `SECTION`, etc etc should be unchanged.
Closes#1938
* 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
This simplified variant supports only a subset of the functionality
in `std::unique_ptr<T>`. `Catch::Detail::unique_ptr<T>` only supports
single element pointer (no array support) with default deleter.
By removing the support for custom deleters, we also avoid requiring
significant machinery to support EBO, speeding up instantiations of
`unique_ptr<T>` significantly. Catch2 also currently does not need
to support `unique_ptr<T[]>`, so that is not supported either.
