// 020-TestCase-1.cpp
// In a Catch project with multiple files, dedicate one file to compile the
// source code of Catch itself and reuse the resulting object file for linking.
// Let Catch provide main():
#define CATCH_CONFIG_MAIN
#include <catch2/catch.hpp>
TEST_CASE( "1: All test cases reside in other .cpp files (empty)", "[multi-file:1]" ) {
}
// ^^^
// Normally no TEST_CASEs in this file.
// Here just to show there are two source files via option --list-tests.
// Compile & run:
// - g++ -std=c++11 -Wall -I$(CATCH_SINGLE_INCLUDE) -c 020-TestCase-1.cpp
// - g++ -std=c++11 -Wall -I$(CATCH_SINGLE_INCLUDE) -o 020-TestCase TestCase-1.o 020-TestCase-2.cpp && 020-TestCase --success
//
// - cl -EHsc -I%CATCH_SINGLE_INCLUDE% -c 020-TestCase-1.cpp
// - cl -EHsc -I%CATCH_SINGLE_INCLUDE% -Fe020-TestCase.exe 020-TestCase-1.obj 020-TestCase-2.cpp && 020-TestCase --success
// Expected test case listing:
//
// prompt> 020-TestCase --list-tests *
// Matching test cases:
// 1: All test cases reside in other .cpp files (empty)
// [multi-file:1]
// 2: Factorial of 0 is computed (fail)
// [multi-file:2]
// 2: Factorials of 1 and higher are computed (pass)
// [multi-file:2]
// 3 matching test cases
