[Wikitech-l] New phpunit tests eat ~1GB of memory

6 Feb 2010

Since the tests were ported from t/ to phpunit's
phase3/maintenance/tests/ in r61938 and other commits running the
tests on my machine takes up to 1GB of memory and grows as it runs
more tests. It seems that phpunit uses the same instance of the php
interpreter for running all the tests.
Is there some way around this? Perhaps phpunit.xml could be tweaked so
that it runs a new php for each test?
Furthermore when I run `make test' I get this:
Time: 03:35, Memory: 1849.25Mb
There were 2 failures:
1) LanguageConverterTest::testGetPreferredVariantUserOption
    Failed asserting that two strings are equal.
    --- Expected
    +++ Actual
    @@ @@
    -tg-latn
    +tg
/home/avar/src/mw/trunk/phase3/maintenance/tests/LanguageConverterTest.php:82
2) Warning
    No tests found in class "ParserUnitTest".
FAILURES!
    Tests: 686, Assertions: 3431, Failures: 2, Incomplete: 34
But when I run phpunit manually on the test then all tests pass:
$ phpunit LanguageConverterTest.php
    PHPUnit 3.4.5 by Sebastian Bergmann.
.........
Time: 23 seconds, Memory: 23.75Mb
OK (9 tests, 34 assertions)
Also after I get "Tests: 686, Assertions: 3431, Failures: 2,
Incomplete: 34" in the first output phpunit doesn't exit and continues
hugging my memory. Why is it still running? It has already run all the
tests.
