run-tests: initial support for running tests with unittest
The unittest package in Python's standard library provides an almost
universal mechanism for defining and running tests. This patch starts
the process of making run-tests.py talk to it.
The main benefit of speaking unittest is that this will enable
Mercurial's tests to be more easily consumed by other testing tools,
like nose. This is useful for 3rd party extensions having their own
test infrastructure, for example.
Running tests in unittest mode will not result in completely sane
behavior until the unittest mode is made the default execution mode.
Expect things like double printing of output until support stabilizes.
Translations are optional:
$ "$TESTDIR/hghave" gettext || exit 80
#if no-outer-repo
Test that translations are compiled and installed correctly.
Default encoding in tests is "ascii" and the translation is encoded
using the "replace" error handler:
$ LANGUAGE=pt_BR hg tip
abortado: n?o foi encontrado um reposit?rio em '$TESTTMP' (.hg n?o encontrado)!
[255]
Using a more accommodating encoding:
$ HGENCODING=UTF-8 LANGUAGE=pt_BR hg tip
abortado: n\xc3\xa3o foi encontrado um reposit\xc3\xb3rio em '$TESTTMP' (.hg n\xc3\xa3o encontrado)! (esc)
[255]
Different encoding:
$ HGENCODING=Latin-1 LANGUAGE=pt_BR hg tip
abortado: n\xe3o foi encontrado um reposit\xf3rio em '$TESTTMP' (.hg n\xe3o encontrado)! (esc)
[255]
#endif
Test keyword search in translated help text:
$ HGENCODING=UTF-8 LANGUAGE=de hg help -k blättern

Check Mercurial specific translation problems in each *.po files, and
tool itself by doctest
$ cd "$TESTDIR"/../i18n
$ python check-translation.py *.po
$ python check-translation.py --doctest
$ cd $TESTTMP
