Grails 2.0集成测试污染？

Question

所以我有一个小的集成测试，总共包含5个测试。运行该测试只会导致所有通过的测试。然而，运行我的整个测试套件会导致5中的4次测试失败。

我最近刚从1.3.7升级到grails-2.0，并从hsqldb切换到h2。

为了解决这个(测试污染)问题，我应该往哪个方向看呢？

集成测试：

class SeriesIntegrationTests extends GrailsUnitTestCase {
    Series series
    Episode episode

    protected void setUp() {
        super.setUp()
        series = new Series(ttdbId: 2348);
        episode = new Episode(ttdbId: 2983, season: 0, episodeNumber: 0, series: series);
    }

    protected void tearDown() {
        super.tearDown()
    }

    void testCreateSeries() {
        series.save()
        assertFalse("should not have validation errors : $series.errors", series.hasErrors())
        assertEquals("should be one series stored in db", 1, Series.count())
    }

    void testCreateEpisode() {
        series.save()
        episode.save()
        assertFalse("should not have validation errors : $episode.errors", episode.hasErrors())
        assertEquals("should be one episode stored in db", 1, Episode.count())
    }

    void testCreateSeriesAndAddEpisode() {
        series.addToEpisodes(episode)
        series.save(flush: true)
        series.refresh()
        assertEquals("series should contain one episode", 1, series.episodes.size())
    }

    void testDeleteSeriesAndCascadeToEpisode() {
        series.addToEpisodes(episode)
        series.save(flush: true)
        series.delete(flush: true)
        assertEquals(0, Episode.count())
        assertEquals(0, Series.count())

    }

    void testDeleteSeriesAndCascadeToBackdropImage() {
        series.backdrop = new Image();
        series.backdrop.binaryData = new byte[0]
        series.save(flush: true)

        assertFalse(series.hasErrors())
        assertEquals(1, Image.count())

        series.delete(flush: true)
        assertEquals(0, Image.count())
    }
}

我的解决方案是将所有单元测试升级为Grails2.0进行测试的方法。当这件事完成后，所有的测试都通过了。因此，单元测试似乎以某种方式污染了集成测试。但只适用于特定的硬件配置。
