TEST_CASE("fibonacci")
{
auto fibonacci = []<typename T = int>() -> std::generator<int>
{
T j = 0;
T i = 1;
co_yield j;
for(;;) {
co_yield i;
T tmp = i;
i += j;
j = tmp;
}
};
CHECK_THAT(fibonacci() | std::views::take(7), Catch::Matchers::RangeEquals(std::array{0, 1, 1, 2, 3, 5, 9}));
}
Expected behavior
FAILED:
CHECK_THAT( fibonacci() | std::views::take(7), Catch::Matchers::RangeEquals(std::array{0, 1, 1, 2, 3, 5, 9}) )
with expansion:
{ 0, 1, 1, 2, 3, 5, 8 } elements are { 0, 1, 1, 2, 3, 5, 9 }
Actual behaviour
FAILED:
CHECK_THAT( fibonacci() | std::views::take(7), Catch::Matchers::RangeEquals(std::array{0, 1, 1, 2, 3, 5, 9}) )
with expansion:
{?} elements are { 0, 1, 1, 2, 3, 5, 9 }
