CasperJS counts each assertion as a Test... That's not right! How to group these?

Question

I'm writing integration tests with CasperJS, but the output has an issue, IMO: it counts each assertion as a test, instead of allowing for tests to have multiple assertions in them (like JUnit, Nunit, etc).

Is there a way to tell Casper that each assertion is actually not a test, but just an assertion?

For example:

casper.test.begin("This is my first test", 3, function(test) {
  test.assert(true);
  test.assert(true);
  test.assert(true);
  test.done();
});

casper.test.begin("This is my second test", 3, function(test) {
  test.assert(true);
  test.assert(true);
  test.assert(true);
  test.done();
});

This will yield this output:

# This is my first test
PASS Subject is strictly true
PASS Subject is strictly true
PASS Subject is strictly true
# This is my second test
PASS Subject is strictly true
PASS Subject is strictly true
PASS Subject is strictly true
PASS 6 tests executed in 0.028s, 6 passed, 0 failed, 0 dubious, 0 skipped.

When I report this on TeamCity, it shows 6 tests passed, which is not true. I have just two tests, not six. Each test makes 3 assertions.

Instead, I'd expect to see the following output:

PASS This is my first test
  - Subject is strictly true
  - Subject is strictly true
  - Subject is strictly true
PASS This is my second test
  - Subject is strictly true
  - Subject is strictly true
  - Subject is strictly true
PASS 2 tests executed in 0.028s, 2 passed, 0 failed, 0 dubious, 0 skipped.

Ideally tests would be grouped by suites according to the file they come from, and each test.begin would signify exactly that: a new test. Having each assertion counting as a test makes no sense at all.

Is there a way to accomplish this?
