Java Question

Functional tests (Jellytools) don't start on netbeans platform

I'm trying to add some functional tests on existing netbeans application.

Info about application: packaged by maven, used netbeans platform 7.3.1.
I've added dependencies how described in this article but got 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)


Does anybody know why it happend? And how to fix it?
Thanks in advance.

UPD1 test class:

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.");
}
}

Answer

I would like to share results of my investigation. I noticed when application was started as usual i saw in output window:

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

but when application was started via nbjubit/jellytool i saw only:

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

so i decided to expand this values and investigated source code. Let's consider a few interesting methods in NbModuleSuite.java :

    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()));
        }


....
        }

As you can see we can set path values in cluster.path.final or all.clusters and use ; : as delimeters. I spent some time to play with this constants and realised that settings didn't set up in pom.xml:

<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>

but this work well:

<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>

I don't know why it happens but I would recommend to use maven section properties to set systemPropertyVariables of maven-surefire-plugin. Good luck!
