The type alias (`using` or `typedef`) is necessary for the `TYPED_TEST_SUITE`
|
||||
macro to parse correctly.
|
||||
|
||||
The optional third argument *`NameGenerator`* allows specifying a class that
|
||||
exposes a templated static function `GetName(int)`. For example:
|
||||
|
||||
```cpp
|
||||
class NameGenerator {
|
||||
public:
|
||||
template <typename T>
|
||||
static std::string GetName(int) {
|
||||
if constexpr (std::is_same_v<T, char>) return "char";
|
||||
if constexpr (std::is_same_v<T, int>) return "int";
|
||||
if constexpr (std::is_same_v<T, unsigned int>) return "unsignedInt";
|
||||
}
|
||||
};
|
||||
TYPED_TEST_SUITE(MyFixture, MyTypes, NameGenerator);
|
||||
```
