我正在使用Arquillian和嵌入式玻璃鱼在新项目中进行测试。我写了7个测试类。如果我单独测试它们，它们都会通过。我用gradle。这是我如何测试一个单独的类：
./gradlew test -Dtest.single=SomeClassTest
我使用重构技巧来避免在每个单独的测试类中创建@Deployment存档，即将@Deployment包装到抽象类中，并且每个测试类都扩展此类。抽象基类看起来像这样：
@RunWith( Arquillian.class )
public abstract class ArquillianJUnitWar {
@Deployment
public static WebArchive createDeployment() {
WebArchive war = ShrinkWrap.create( WebArchive.class, "test.war" )
.addPackages( true, Filters.exclude( ".*Test.*" ),
"project.package", "arquillian.stub", "arquillian.util" )
.addClasses( Foo.class )
.addAsWebInfResource( "beans-test.xml", "beans.xml" )
.addAsWebInfResource( "web-test.xml", "web.xml" )
.addAsResource( "persistence-test.xml", "META-INF/persistence.xml" );
return war;
}
}
测试类看起来像这样：
public class SomeClassTest extends ArquillianJUnitWar {
@Test
public void testSomeMethod() {
// do something
}
}
我在之前的项目中使用过这个技巧，我使用Arquillian和嵌入式焊接进行测试。它工作得很好。
然而，这次我得到随机失败，我不确定这个重构技巧是否与失败有关。在任何情况下，当我使用
进行干净的完整测试时./gradlew clean test
我的测试将随机失败。如前所述，它们都通过了单独的测试运行。
随机失败的堆栈跟踪之一如下所示：
