TTS_NO_THROW

#define TTS_NO_THROW	(		EXPR,
			... )

#include <tts/test/exceptions.hpp>

Checks if a given expression throws no exception.

Parameters

EXPR	Expression to evaluate.
...	Optional tag. If equals to REQUIRED, this test will stop the program if it fails.

Example

#define TTS_MAIN // No need for main()
#include <tts/tts.hpp>
 
void bar()
{
  // This function is marked as noexcept, so it should not throw any exceptions.
  // If it does, the test framework should detect this and report it as a failure.
  // In this case, we are not throwing anything, so the test should pass.
}
 
TTS_CASE("Check that nothrow function are detected as such")
{
  TTS_NO_THROW(bar());
};

TTS_THROW

#define TTS_THROW	(		EXPR,
			EXCEPTION,
			... )

#include <tts/test/exceptions.hpp>

Checks if a given expression throws an exception of a given type.

Parameters

EXPR	Expression to evaluate.
EXCEPTION	Expected exception type to be thrown.
...	Optional tag. If equals to REQUIRED, this test will stop the program if it fails.

Example

#define TTS_MAIN // No need for main()
#include <tts/tts.hpp>
 
struct some_exception_type
{
};
 
void foo()
{
  throw some_exception_type();
}
 
TTS_CASE("Check that we can capture thrown exceptions")
{
  TTS_THROW(foo(), some_exception_type);
};
