For code:
```c++
#include <compare>
struct foo {
char value;
friend auto operator<=>(foo, foo) = default;
};
int main() {
auto a1 = foo{0} <=> foo{1};
auto a2 = foo{1} <=> foo{0};
auto a3 = foo{0} <=> foo{0};
}
```
There shouldn't be any missing branch. But some `false` path is never taken. This makes 100% test-coverage impossible.
```
1| |#include <compare>
2| |
3| |struct foo {
4| | char value;
5| 15| friend auto operator<=>(foo, foo) = default;
------------------
| Branch (5:45): [True: 100.00%, False: 0.00%]
------------------
6| |};
7| |
8| 1|int main() {
9| 1| auto a1 = foo{0} <=> foo{1};
10| 1| auto a2 = foo{1} <=> foo{0};
11| 1| auto a3 = foo{0} <=> foo{0};
12| 1|}
```
This happens to other types I tried even `std::string`
![]()
