java - 功能测试 (Jellytools) 不在 netbeans 平台上启动

Question

我正尝试在现有的 netbeans 应用程序上添加一些功能测试。
应用信息:maven打包，使用netbeans platform 7.3.1。我添加了此 article 中描述的依赖项但有异常(exception):

Running qa.FuncTest
Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0.067 sec <<< FAILURE! - in qa.FuncTest
org.netbeans.junit.NbModuleSuite$S@67ad77a7(org.netbeans.junit.NbModuleSuite$S)  Time elapsed: 0.066 sec  <<< ERROR!

    at org.netbeans.junit.NbModuleSuite$S.access$100(NbModuleSuite.java:667)

有人知道为什么会这样吗？以及如何解决？提前致谢。

UPD 来自 application/pom.xml 的依赖部分

UPD1测试类:

package qa;

import junit.framework.Test;
import org.netbeans.jellytools.JellyTestCase;
import org.netbeans.jellytools.OptionsOperator;
import org.netbeans.junit.NbModuleSuite;
import org.openide.windows.TopComponent;

public class FuncTest extends JellyTestCase {

    public static Test suite() {
        return NbModuleSuite.allModules(FuncTest.class);
    }

    public FuncTest(String n) {
        super(n);
    }

    public void testWhatever() throws Exception {
        TopComponent tc = new TopComponent();
        tc.setName("label");
        tc.open();
        OptionsOperator.invoke().selectMiscellaneous();
        Thread.sleep(5000);
        System.err.println("OK.");
    }
}

我想分享我的调查结果。我注意到应用程序何时像往常一样启动，我在输出窗口中看到:

  Installation            =.../application/target/application/extra
                           .../application/target/application/java
                           .../application/target/application/kws
                           .../application/target/application/platform

但是当通过 nbjubit/jellytool 启动应用程序时，我只看到:

  Installation            =.../application/target/application/platform

所以我决定扩展这个值并研究源代码。让我们考虑 NbModuleSuite.java 中的一些有趣的方法:

    private static String[] tokenizePath(String path) {
        List<String> l = new ArrayList<String>();
        StringTokenizer tok = new StringTokenizer(path, ":;", true); // NOI18N


    .....
        }

static File findPlatform() {
        String clusterPath = System.getProperty("cluster.path.final"); // NOI18N
        if (clusterPath != null) {
            for (String piece : tokenizePath(clusterPath)) {
                File d = new File(piece);
                if (d.getName().matches("platform\\d*")) {
                    return d;
                }
            }
        }
        String allClusters = System.getProperty("all.clusters"); // #194794
        if (allClusters != null) {
            File d = new File(allClusters, "platform"); // do not bother with old numbered variants
            if (d.isDirectory()) {
                return d;
            }
        }


    ....
        }

static void findClusters(Collection<File> clusters, List<String> regExps) throws IOException {
        File plat = findPlatform().getCanonicalFile();
        String selectiveClusters = System.getProperty("cluster.path.final"); // NOI18N
        Set<File> path;
        if (selectiveClusters != null) {
            path = new TreeSet<File>();
            for (String p : tokenizePath(selectiveClusters)) {
                File f = new File(p);
                path.add(f.getCanonicalFile());
            }
        } else {
            File parent;
            String allClusters = System.getProperty("all.clusters"); // #194794
            if (allClusters != null) {
                parent = new File(allClusters);
            } else {
                parent = plat.getParentFile();
            }
            path = new TreeSet<File>(Arrays.asList(parent.listFiles()));
        }


....
        }

如您所见，我们可以在 cluster.path.final 或 all.clusters 中设置路径值并使用 ; : 作为分隔符。我花了一些时间来研究这个常量，并意识到设置没有在 pom.xml 中设置:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>${software.maven-surefire-plugin}</version>
    <configuration>
        <skipTests>false</skipTests>
        <systemPropertyVariables>
            <branding.token>${brandingToken}</branding.token>
            <!--problem part start-->
            <property>
                <name>cluster.path.final</name>
                <value>${project.build.directory}/${brandingToken}/platform:${project.build.directory}/${brandingToken}/java:...etc</value>
            </property>
            <!--problem part end-->
        </systemPropertyVariables>
    </configuration>
</plugin>

但这很好用:

<properties>
    <cluster.path.final>${project.build.directory}/${brandingToken}/platform:${project.build.directory}/${brandingToken}/java:...etc</cluster.path.final>
</properties>
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>${software.maven-surefire-plugin}</version>
    <configuration>
        <skipTests>false</skipTests>
        <systemPropertyVariables>
            <branding.token>${brandingToken}</branding.token>
            <cluster.path.final>${cluster.path.final}</cluster.path.final>
        </systemPropertyVariables>
    </configuration>
</plugin>

我不知道为什么会这样，但我建议使用 Maven 部分 properties 来设置 maven-surefire-plugin 的 systemPropertyVariables。祝你好运!
