A modern, C++-native, test framework for unit-tests, TDD and BDD - using C++14, C++17 and later (C++11 support is in v2.x branch, and C++03 on the Catch1.x branch)
0354d50278
When using C++11, comparison operators are already templated to take anything that can be explicitly converted to double, but constructor took only doubles. This lead to warnings when an `Approx` was constructed from floats, which was problematic for some users. Since just adding float constructor would be a large breaking change, as suddenly `Approx( 1 )` would become ambiguous, I added a templated constructor that will take anything that is explicitly convertible to double. This has the added benefit of allowing constructing `Approx` instances from instances of strong typedefs, ie allowing `calculated_temp == Approx( known_temp)`. Closes #873 |

What's the Catch?
Catch stands for C++ Automated Test Cases in Headers and is a multi-paradigm automated test framework for C++ and Objective-C (and, maybe, C). It is implemented entirely in a set of header files, but is packaged up as a single header for extra convenience.
