[bind10-dev] having fail tests in gtest

[JINMEI Tatuya / 神明達哉]

According to today's meeting I've (re)checked the googletest manual
page and found how to have failing tests without 'if 0' them:
http://code.google.com/p/googletest/wiki/GoogleTestAdvancedGuide#Temporarily_Disabling_Tests

I adopted this in r1798 for one test that currently fails.

This test case is now built, but 'make check' simply ignores it:
...
[----------] Global test environment tear-down
[==========] 240 tests from 35 test cases ran. (306 ms total)
[  PASSED  ] 240 tests.

  YOU HAVE 1 DISABLED TEST

But you can manually force it to be tested (which would fail, of
course):

% ./run_unittests --gtest_also_run_disabled_tests
...
[----------] Global test environment tear-down
[==========] 241 tests from 35 test cases ran. (304 ms total)
[  PASSED  ] 240 tests.
[  FAILED  ] 1 test, listed below:
[  FAILED  ] Rdata_DS_Test.DISABLED_badText_DS

 1 FAILED TEST
