hi, fellows

I'd like to intruduce a new unit test framework for C++
freely available at:

http://unit--.sourceforge.net/

It does not need bothering test registration, here is an example

// --- begin code ---
#include "unit--.h"

testSuite(MySuite);

testCase(CompareCase, MySuite)
{
int x = 1;
int y = x + 2;
assertTrue(x < y);
}
// --- end code ---

besides, unit-- is implemented entirely in std C++, thus is portable
across different platforms and compilers

Righteous. CppUnit mires itself in endless test registration issues, instead
of simply using macros to achieve the Test Collector pattern.

}

Suppose I had two suites and wanted to run the same case over both suites?

Suppose a test case uses std::basic_string<>. How would I run the test case
twice, once with char and again with wchar_t?

Contrarily, at error time, your editor should present the option to navigate
to a failure, the same as syntax errors.

That one always squicks me out.

Specifically, it relies on excessive test registration calls, and doesn't
use any Test Collector, despite otherwise freely abusing macros...

we might consider that they are different test cases,

but they have code in common.

"extract method"
(http://www.refactoring.com/catalog/extractMethod.html)
could work for this scenario.
assertTrue() can effect in functions invoked by a testCase

here is an example:

// --- begin code ---
#include <vector>
#include <numeric>
#include <algorithm>
#include "../unit--.h"

testSuite(TemplateSuite)

template <typename T>
void testAlgorithms()
{
using namespace std;
using namespace unit_minus;
vector<T> ve(100, 1);
partial_sum(ve.begin(), ve.end(), ve.begin());

assertTrue(ve.size() > 0);
assertTrue(1 == ve[0]);
for (unsigned i = 1; i < ve.size(); ++i) {
assertTrue(ve[i - 1] + 1 < ve[i]);
}
}

namespace {
testCase(IntCase, TemplateSuite)
{
testAlgorithms<int>();
}

testCase(UnsignedCase, TemplateSuite)
{
testAlgorithms<unsigned>();
}

} // namespace
// --- end code ---

Thanks!

One use of AbstractTest is to turn a cases' setUp() and tearDown() into an
abstract factory. setUp() will create a different type, so a common case
body can work across a range of types. Your code doesn't need this effect
because your assertions are not members of the basic TestCase class.

(Assertions are typically macros, so I mean macros are members when they use
member variables inside them.)
