CMake 3.19 introduces new add_test() behavior guarded with the policy
CMP0110.
See: https://cmake.org/cmake/help/latest/policy/CMP0110.html
Update the helper script ParseAndAddCatchTests to consider the policy and
handle the test case name accordingly.
The problem was that Catch2 did not reliably include `<exception>`
before it checked for the feature test macro for
`std::uncaught_exceptions`. To avoid overhead of including
`<exception>` everywhere, the configuration check was split out
into a separate header.
Closes#2021
As far as I understand the standard, if there is a function called
`rng` in the global namespace, and a function argument called `rng`,
then the argument should shadow the function. This then means that
uses of `rng` inside the function should refer to the argument.
This is not the case for AppleClang 12.0.0. Luckily the workaround
is simple enough; just rename the argument. Given that the function
is 3 lines and uncomplicated, the change of the name doesn't really
affect readability.
Still, WTF AppleClang?
Closes#2030
* Change regex to allow parentheses inside the test macro for a type list
* Append a wildcard to the CTestName if the test case is a template
* Also change the regular expression so parentheses are allowed in names
(fixes#1848)
With CMake 3.18.0 the `add_test(NAME)` handling changed. The escaped
double quotes confuse the new call. Work around this upstream change.
fixes: https://github.com/catchorg/Catch2/issues/1984
TAP format requires all results to be reported.
Removed extraneous preferences function (handled by parent)
Incorporated fix from 3d9e7db2e0
Simplified total printing
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
A test runner already has a --durations option to print durations.
However, this isn't entirely satisfactory.
When there are many tests, this produces output spam which makes it hard
to find the test failure output. Nevertheless, it is helpful to be
informed of tests which are unusually slow.
Therefore, introduce a new option --min-duration that causes all
durations above a certain threshold to be printed. This allows slow
tests to be visible without mentioning every test.
There are some examples on issue #850 of using this feature, but they
are not easily found from the documentation. Adding them here as an
example makes them more findable and ensures they keep working if the
API changes.
