Why is PHPUnit creating the output “S” for a test that passes?

问题

I'm using PHPUnit in Eclipse IDE and this is the output when running my unit test:

PHPUnit 3.7.28 by Sebastian Bergmann.

.S.........

Time: 190 ms, Memory: 5.50Mb

OK (10 tests, 45 assertions)

The output has an S which suggests that a test is being skipped. However, there is no message "Skipped: 1".

According to the manual, the test output should look like this:

.S.........    
Time: 190 ms, Memory: 5.50Mb

1) UnitTest_Directory_Test::testBenthicCover
The MySQLi extension is not available.
/home/sb/DatabaseTest.php:9

OK, but incomplete or skipped tests!
OK (10 tests, 45 assertions, Skipped: 1)

Is the test actually passing, or is it being skipped?

Why do I not see Skipped: 1?

_{Environment: PHPUnit 3.7.28, Eclipse Java EE IDE, Version: Helios Service Release 2}

I've logged the test results in json format for debugging:
