Template tests: added TEMPLATE_PRODUCT_TEST_CASE support for generating test cases based on multiple template template types combined with template arguments for each of the template template types specified e.g. ``` TEMPLATE_PRODUCT_TEST_CASE("template product","[template]", (std::tuple, std::pair, std::map), ((int,float),(char,double),(int,char))) ``` will effectively create 9 test cases with types: std::tuple<int,float> std::tuple<char,double> std::tuple<int,char> std::pair<int,float> std::pair<char, double> std::pair<int,char> std::map<int,float> std::map<char,double> std::map<int,char> Tested type is accessible in test case body as TestType Unique name is created by appending ` - <index>` to test name since preprocessor has some limitations in recursions Closes #1454 2018-12-06 19:27:33 +01:00			`/*`

Add nice error messages for unsupported && and \|\| As explained in issue #1273, `operator&&` and `operator\|\|` should give a proper compile time error on use instead of the compiler complaining about them not being defined. This commit adds an `always_false` type in `catch_meta.hpp` used for implementing a nice `static_assert` for both of the abovementioned operators.

Namespace our type traits in catch_meta Previously they could conflict with user-defined type traits that were in the global namespace. Fixes #1548 2019-02-23 21:06:16 +01:00			`namespace Catch {`
Nttp support Closes #1531 2019-04-17 20:23:24 +02:00			`template<typename T>`
