也许有人可以帮助我,我试图写我的第一个gwt单元测试,但这是问题,当我运行我的测试与maven我得到这个错误：
> java.lang.NoClassDefFoundError: com/google/gwt/dev/cfg/Condition at > com.google.gwt.junit.client.GWTTestCase.createStrategy(GWTTestCase.java:340) > at > com.google.gwt.junit.client.GWTTestCase.getStrategy(GWTTestCase.java:257) > at > com.google.gwt.junit.client.GWTTestCase.getSyntheticModuleName(GWTTestCase.java:275) > at > com.google.gwt.junit.client.GWTTestCase.setName(GWTTestCase.java:321) > at junit.framework.TestSuite.createTest(TestSuite.java:63) at > junit.framework.TestSuite.addTestMethod(TestSuite.java:283) at > junit.framework.TestSuite.<init>(TestSuite.java:146) at > org.junit.internal.runners.JUnit38ClassRunner.<init>(JUnit38ClassRunner.java:71) > at > org.junit.internal.builders.JUnit3Builder.runnerForClass(JUnit3Builder.java:14) > at > org.junit.runners.model.RunnerBuilder.safeRunnerForClass(RunnerBuilder.java:57) > at > org.junit.internal.builders.AllDefaultPossibilitiesBuilder.runnerForClass(AllDefaultPossibilitiesBuilder.java:29) > at > org.junit.runners.model.RunnerBuilder.safeRunnerForClass(RunnerBuilder.java:57) > at > org.junit.internal.requests.ClassRequest.getRunner(ClassRequest.java:24) > at > org.apache.maven.surefire.junit4.JUnit4TestSet.<init>(JUnit4TestSet.java:45) > at > org.apache.maven.surefire.junit4.JUnit4DirectoryTestSuite.createTestSet(JUnit4DirectoryTestSuite.java:56) > at > org.apache.maven.surefire.suite.AbstractDirectoryTestSuite.locateTestSets(AbstractDirectoryTestSuite.java:96) > at > org.apache.maven.surefire.Surefire.createSuiteFromDefinition(Surefire.java:209) > at org.apache.maven.surefire.Surefire.run(Surefire.java:156) at > sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at > sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) > at > sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) > at java.lang.reflect.Method.invoke(Method.java:601) at > org.apache.maven.surefire.booter.SurefireBooter.runSuitesInProcess(SurefireBooter.java:345) > at > org.apache.maven.surefire.booter.SurefireBooter.main(SurefireBooter.java:1009) > Caused by: java.lang.ClassNotFoundException: > com.google.gwt.dev.cfg.Condition at > java.net.URLClassLoader$1.run(URLClassLoader.java:366) at > java.net.URLClassLoader$1.run(URLClassLoader.java:355) at > java.security.AccessController.doPrivileged(Native Method) at > java.net.URLClassLoader.findClass(URLClassLoader.java:354) at > java.lang.ClassLoader.loadClass(ClassLoader.java:423) at > sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at > java.lang.ClassLoader.loadClass(ClassLoader.java:356)
这是我的testCase：
public class TelekanalServiceImplTest extends GWTTestCase {
@Override
public String getModuleName() {
// TODO Auto-generated method stub
return "com.karq.tvkava.tvkavaJUnit";
}
public void testTelekanalService(){
// Create the service that we will test.
TelekanalServiceAsync telekanalService = GWT.create(TelekanalService.class);
ServiceDefTarget target = (ServiceDefTarget) telekanalService;
target.setServiceEntryPoint(GWT.getModuleBaseURL() + "tvkava/telekanalService");
// Since RPC calls are asynchronous,we will need to wait for a response
// after this test method returns. This line tells the test runner to wait
// up to 10 seconds before timing out.
delayTestFinish(10000);
//Test data
Telekanal telekanal = new Telekanal();
telekanal.setNimetus("test");
telekanal.setKirjeldus("see on test");
// Send a request to the server.
telekanalService.saveOrUpdateTelekanal(telekanal,new AsyncCallback<Void>() {
public void onFailure(Throwable caught) {
// The request resulted in an unexpected error.
fail("Request failure: " + caught.getMessage());
}
public void onSuccess(Void result) {
// Verify that the response is correct.
boolean isSaved = true;
assertTrue(isSaved);
// Now that we have received a response,we need to tell the test runner
// that the test is complete. You must call finishTest() after an
// asynchronous test finishes successfully,or the test will time out.
finishTest();
}
});
}
}
在com.karq.tvkava中,我有一个名为tvKavaJUnit.gwt.xml的模块文件
<?xml version="1.0" encoding="UTF-8"?> <module> <!-- Inherit our applications main module. --> <inherits name='com.karq.tvkava.tvkava'/> <!-- Specify the path to any remote services. --> <servlet path="/tvkava/telekanalService" class="com.karq.tvkava.server.services.TelekanalServiceImpl" /> </module>
而且我的主要模块在com.karq.tvkava和它的名为tvkava.gwt.xml
<?xml version="1.0" encoding="UTF-8"?> <module rename-to='tvkava'> <!-- Inherit the core Web Toolkit stuff. --> <inherits name='com.google.gwt.user.User'/> <!-- Inherit the default GWT style sheet. You can change --> <!-- the theme of your GWT application by uncommenting --> <!-- any one of the following lines. --> <inherits name='com.google.gwt.user.theme.standard.Standard'/> <!-- <inherits name='com.google.gwt.user.theme.chrome.Chrome'/> --> <!-- <inherits name='com.google.gwt.user.theme.dark.Dark'/> --> <!-- Other module inherits --> <inherits name='net.sf.gilead.Gilead4Gwt'/> <source path='client/service' /> <source path='shared'/> <!-- Specify the app entry point class. --> <entry-point class='com.karq.tvkava.client.tvkava'/> <!-- Specify the paths for translatable code --> <source path='client'/> <source path='shared'/> </module>
解决方法
我设法使Surefire与我的GWT测试无缝工作,输出正确的结果,并在出现测试失败时失败.在我的POM中,我已经设置了Surefire：
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.12</version>
<configuration>
<additionalClasspathElements>
<additionalClasspathElement>${project.build.sourceDirectory}</additionalClasspathElement>
<additionalClasspathElement>${project.build.testSourceDirectory}</additionalClasspathElement>
</additionalClasspathElements>
<useSystemClassLoader>true</useSystemClassLoader>
<useManifestOnlyJar>false</useManifestOnlyJar>
<forkMode>always</forkMode>
<systemProperties>
<property>
<name>gwt.args</name>
<value>-out www-test</value>
</property>
</systemProperties>
</configuration>
</plugin>
您需要定义变量project.build.sourceDirectory和project.build.testSourceDirectory.对我而言,它们类似于< project-name> / src / main / java和< project-name> / src / test / java.
我也不得不添加依赖于gwt-dev：
<dependency>
<groupId>com.google.gwt</groupId>
<artifactId>gwt-dev</artifactId>
<version>2.4.0</version>
<scope>provided</scope>
</dependency>
