$section Object that Runs a Group of Tests$$

$head Syntax$$
$codei%test_boolofvoid %Run%(%group%, %width%)
%$$
$icode%Run%(%test%, %name%)
%$$
$icode%ok% = %Run%.summary(%memory_ok%)%$$

$head Purpose$$
The object $icode Run$$ is used to run a group of tests functions
and report the results on standard output.

$head group$$
The argument has prototype
$codei%
	const std::string& %group%
%$$
It is the name for this group of tests.

$head width$$
The argument has prototype
$codei%
	size_t %width%
%$$
It is the number of columns used to display the name of each test.
It must be greater than the maximum number of characters in a test name.

$head test$$
The argument has prototype
$codei%
	bool %test%(void)
%$$
It is a function that returns true (when the test passes) and false
otherwise.

$head name$$
The argument has prototype
$codei%
	const std::string& %name%
%$$
It is the name for the corresponding $icode test$$.

$head memory_ok$$
The argument has prototype
$codei%
	bool %memory_ok%
%$$
It is false if a memory leak is detected (and true otherwise).

$head ok$$
This is true if all of the tests pass (including the memory leak test),
otherwise it is false.

$head Example$$
See any of the main programs in the example directory; e.g.,
$code example/ipopt_solve.cpp$$.
