For migrating test dependencies from nbproject/project.properties to nbproject/project.xml was implemented fix-test-dependencies ant task in NetBeans module project. You can do it from command line:
cd your_nbm_project_dir ant fix-test-dependencies
GUI for adding/removing test dependencies has not yet been implemented. I hope it will be available early. It can by done only manually by editing project.xml file. The tags for test dependencies (defined in xml schema) are described below:
<test-dependencies>
<! -- Dependencies for a source root with tests: -->
<test-type>
<!--
Name of test type. Normally you will use 'unit'.
netbeans.org modules also support 'qa-functional' test-type.
-->
<name>unit</name>
<!-- A dependency on a module or its tests: -->
<test-dependency>
<!-- Identification of module our tests depend upon: -->
<code-name-base>org.netbeans.modules.java.project</code-name-base>
<!-- Include also transitive module dependencies of that module: -->
<recursive/>
<!-- Always available when running, but to include at compile time also: -->
<compile-dependency/>
<!-- To request the tests of that module, rather than itself: -->
<test/>
</test-dependency>
</test-type>
</test-dependencies>
Source root for a test type: {project.dir}/test/${test-type.name}/src {project.dir}/test/unit/src - source root for unit test
For example you have three modules with code name bases A,B,C. A depends on B, B depends on C. You want to add test dependencies to unit test type of module D:
Use case 1: Runtime dependency on module.
<test-type>
<name>unit</name>
<test-dependency>
<code-name-base>A</code-name-base>
</test-dependency>
</testtype>
Use case 2: Runtime dependency on a module and its recursive runtime classpath.
<test-type>
<name>unit</name>
<test-dependency>
<code-name-base>A</code-name-base>
<recursive/>
</test-dependency>
</test-type>
Use case 3: Compile and runtime dependency on a module its recursive runtime classpath.
<test-type>
<name>unit</name>
<test-dependency>
<code-name-base>A</code-name-base>
<compile-dependency/>
<recursive/>
</test-dependency>
</test-type>
Use case 4: Compile and runtime dependency on a module, its recursive runtime classpath and tests.
<test-type>
<name>unit</name>
<test-dependency>
<code-name-base>A</code-name-base>
<compile-dependency/>
<recursive/>
<test/>
</test-dependency>
</test-type>
External testing libraries (are not NetBeans modules) can be specified in nbproject/project.properties file. For unit test are defined two properties
