using_xtd_tunit_assert_without_tunit_app.cpp

Shows how to use xtd.tunit assert methods like xtd::tunit::assert in a xtd.console or xtd.forms application.

#include <xtd/xtd>
 
class program {
public:
  static auto main() {
    auto items = array {10, 20, 30};
    
    tunit::assert::is_greater_or_equal(items.count(), 4, "The items count is less than 4");
    // Same as two following lines
    //diagnostics::debug::cassert(items.count() >= 4, "The items count is less than 4");
    //assert_(items.count() >= 4, "The items count is less than 4");
    println(items[3]);
  }
};
 
startup_(program::main);
