Bug 142579

Is this going to be implemented for 6.5? Is there a corresponding issue for apisupport/project? Seems misleading for
issue #72080 to be marked FIXED when in fact you cannot use it yet.

Partially implemented - for the case that "Compile on Save" is enabled.

It is going to be implemented. I just filed an issue for apisupport/project: #142763.

Integrated into 'main-golden', available in build *200808041401* on http://bits.netbeans.org/dev/nightly/
Changeset: http://hg.netbeans.org/main/rev/bf6e5ac3b136
User: Marian Petras <mpetras@netbeans.org>
Log: Partially implemented support for execution/debugging of a single test method (task #142579) - for "compile on save" only for now.

Marian: It seems that "methodname" is now a permitted parameter for ProjectRunner.QUICK_TEST{,_DEBUG} yet this fact is
not documented. It needs to be.

Marian: while Run Again seems to work, Debug runs all the tests in the suite in the debugger.

FYI: adding comparable support to automatic projects, in contrib #8523feba7521.

I just found the cause of the issue when debugging. The problem is in the classpath. When a test is to be debugged, it
is started with the following command (template):

        <java classname="org.apache.tools.ant.taskdefs.optional.junit.JUnitTestRunner" fork="true"
                                                                                       dir="${work.dir}"
                                                                                       jvm="${platform.java}">
            <classpath>
                <path path="${ant.home}/lib/ant.jar:${ant.home}/lib/ant-junit.jar"/>
                <path path="${classpath-translated}"/>
            </classpath>
                    ...
                </java>

The substantial thing is that the classpath does not contain the Ant patch that modifies the JUnitTestRunner such that
it accepts (and uses) command-line argument "methods=...". The fix is to put the .jar containing the patch to the
classpath such that it is before "ant-junit.jar". To make it working also with other Ant patches, I will put it to the
beginning of the classpath:

            <classpath>
                <fileset dir="${ant.home}" includes="patches/*.jar"/>
                <path path="${ant.home}/lib/ant.jar:${ant.home}/lib/ant-junit.jar"/>
                <path path="${classpath-translated}"/>
            </classpath>

<fileset dir="${ant.home}" includes="patches/*.jar"/> sounds good to me. I guess I should have opened a separate issue.

Separate issue against which module? I looked at the Ant build script and an ideal solution would be to define a
classpath for Ant and assign it a specific Id (<path id="...">). This path would contain ${ant.home}/lib/ant.jar and all
Ant patches. All the tasks could then use this path using <path refid="...">). But I do not know whether it is
acceptable as almost any change of Ant script is also an API change.

Oh, you are talking about running/debugging a single test method from the regular Ant script. I did not even realize
there was any plan to support that. I was talking about Quick Run/Debug on tests, which seems more useful and is anyway
much simpler to implement: to make Debug work from the JUnit Results Window you need only change

java.source.ant/src/org/netbeans/modules/java/source/ant/resources/junit-debug-snippet.xml

to include ant/patches/*.jar in the classpath.

I have already committed (but not pushed yet) the fix in junit-debug-snippet.xml.

I pushed the fix of junit-debug-snippet.xml:

http://hg.netbeans.org/main/rev/c9208633ed4e

I can confirm that #c9208633ed4e enables debug single test method for Google Guice dev sources opened as an automatic
project.

Already works with CoS enabled; just need it to be made to work also with CoS off (i.e. using build-impl.xml).
