Built by Maven

tycho-surefire:test

Full name:

org.eclipse.tycho:tycho-surefire-plugin:2.7.5:test

Description:

Executes tests in an OSGi runtime.

The goal launches an OSGi runtime and executes the project's tests in that runtime. The "test runtime" consists of the bundle built in this project and its transitive dependencies, plus some Equinox and test harness bundles. The bundles are resolved from the target platform of the project. Note that the test runtime does typically not contain the entire target platform. If there are implicitly required bundles (e.g. org.apache.felix.scr to make declarative services work), they need to be added manually through an extraRequirements configuration on the target-platform-configuration plugin.

Attributes:

  • Requires a Maven project to be executed.
  • Requires dependency resolution of artifacts in scope: runtime.
  • The goal is thread-safe and supports parallel builds.
  • Binds by default to the lifecycle phase: integration-test.

Optional Parameters

Name Type Since Description
<appArgLine> String - Arbitrary applications arguments to set on the command line.
<application> String - Eclipse application to be run. If not specified, default application org.eclipse.ui.ide.workbench will be used. Application runnable will be invoked from test harness, not directly from Eclipse. Note that you need to ensure that the bundle which defines the configured application is included in the test runtime.
<argLine> String - Arbitrary JVM options to set on the command line.
User property is: tycho.testArgLine.
<bundleStartLevel> BundleStartLevel[] - Bundle start level and auto start configuration used by the test runtime. Ignored if testRuntime is p2Installed. Example:

  <bundle>
    <id>foo.bar.myplugin</id>
    <level>6</level>
    <autoStart>true</autoStart>
  </bundle>
</bundleStartLevel>

<debugOptions> String - if set to a non-null value, the platform is put in debug mode. If the value is a non-empty string it is interpreted as the location of the .options file. This file indicates what debug points are available for a plug-in and whether or not they are enabled. for a list of available options see https://git.eclipse.org/c/equinox/rt.equinox.framework.git/plain/bundles/org.eclipse.osgi/.options
User property is: osgi.debug.
<debugPort> int - Set this parameter to suspend the test JVM waiting for a client to open a remote debug session on the specified port. If further customization of JVM debug parameters is required then argLine can be used instead.
User property is: debugPort.
<defaultStartLevel> BundleStartLevel - The default bundle start level and auto start configuration used by the test runtime for bundles where the start level/auto start is not configured in bundleStartLevel. Ignored if testRuntime is p2Installed. Example:

    <level>6</level>
    <autoStart>true</autoStart>
  </defaultStartLevel>

<deleteOsgiDataDirectory> boolean - Whether to recursively delete the directory osgiDataDirectory before running the tests.
Default value is: true.
<dependencies> Dependency[] - Additional dependencies to be added to the test runtime. Ignored if testRuntime is p2Installed. Note: This parameter has only limited support for dependencies to artifacts within the reactor. Therefore it is recommended to specify extraRequirements on the target-platform-configuration plugin instead. Example: 
<plugin>
   <groupId>org.eclipse.tycho</groupId>
   <artifactId>target-platform-configuration</artifactId>
   <version>${tycho-version}</version>
   <configuration>
      <dependency-resolution>

            </requirement>
         </extraRequirements>
      </dependency-resolution>

<testRuntime> String 0.19.0 How to create the OSGi test runtime. Allowed values are default and p2Installed. Mode p2Installed is EXPERIMENTAL - only works when installing products under test (see below).
  • In default mode, all necessary files to define the test runtime like config.ini are generated by tycho. This installation mode has the advantage that the test runtime is minimal (defined by the transitive dependencies of the test bundle plus and the test harness) and existing bundle jars are referenced rather than copied for the installation
  • In p2Installed mode, use p2 director to install test bundle, test harness bundles and respective dependencies. This installation mode can be used for integration tests that require a fully p2-provisioned installation. To install a product IU, add it as extra requirement to the test bundle (see example below). Note that this installation mode comes with a certain performance overhead for executing the provisioning operations otherwise not required.
Example configuration which will install product IU under test "example.product.id" using p2: 
<plugin>
   <groupId>org.eclipse.tycho</groupId>
   <artifactId>tycho-surefire-plugin</artifactId>
   <version>${tycho-version}</version>
   <configuration>
      <testRuntime>p2Installed</testRuntime>
   </configuration>
</plugin>
<plugin>
   <groupId>org.eclipse.tycho</groupId>
   <artifactId>target-platform-configuration</artifactId>
   <version>${tycho-version}</version>
   <configuration>
      <dependency-resolution>
         <extraRequirements>
            <!-- product IU under test -->
            <requirement>
               <type>p2-installable-unit</type>
               <id>example.product.id</id>
               <versionRange>0.0.0</versionRange>
            </requirement>
         </extraRequirements>
      </dependency-resolution>
   </configuration>
</plugin>

Default value is: default.
<threadCount> int 0.16.0 (JUnit 4.7 provider) The attribute thread-count allows you to specify how many threads should be allocated for this execution. Only makes sense to use in conjunction with the parallel parameter.
User property is: threadCount.
<trimStackTrace> boolean 1.3.0 When true, stack traces are trimmed to only show lines within the test.
Default value is: true.
User property is: trimStackTrace.
<useJDK> ToolchainProvider$JDKUsage - Which JDK to use for executing tests. Possible values are: SYSTEM, BREE .
  • SYSTEM: Use the currently running JVM (or from toolchain if configured in pom.xml)
  • BREE: use MANIFEST header Bundle-RequiredExecutionEnvironment to lookup the JDK from toolchains.xml. The value of BREE will be matched against the id of the toolchain elements in toolchains.xml.
Example for BREE:
In META-INF/MANIFEST.MF: 
Bundle-RequiredExecutionEnvironment: JavaSE-1.7
In toolchains.xml: 
<toolchains>
   <toolchain>
      <type>jdk</type>
      <provides>
         <id>JavaSE-1.7</id>
      </provides>
      <configuration>
         <jdkHome>/path/to/jdk/1.7</jdkHome>
      </configuration>
   </toolchain>
</toolchains>

Default value is: SYSTEM.
<useUIHarness> boolean - Run tests using UI (true) or headless (false) test harness.
Default value is: false.
<useUIThread> boolean - Run tests in UI (true) or background (false) thread. Only applies to UI test harness.
Default value is: true.
<useUnlimitedThreads> boolean 0.16.0 (JUnit 4.7 provider) Indicates that the thread pool will be unlimited. The parallel parameter and the actual number of classes/methods will decide. Setting this to "true" effectively disables perCoreThreadCount and threadCount.
Default value is: false.
User property is: useUnlimitedThreads.
<work> File - Root directory (osgi.install.area) of the Equinox runtime used to execute tests.
Default value is: ${project.build.directory}/work.

<threadCount>

(JUnit 4.7 provider) The attribute thread-count allows you to specify how many threads should be allocated for this execution. Only makes sense to use in conjunction with the parallel parameter.
  • Type: int
  • Since: 0.16.0
  • Required: No
  • User Property: threadCount

<trimStackTrace>

When true, stack traces are trimmed to only show lines within the test.
  • Type: boolean

  • Required: No
  • User Property: trimStackTrace
  • Default: true

<useJDK>

Which JDK to use for executing tests. Possible values are: SYSTEM, BREE .
  • SYSTEM: Use the currently running JVM (or from toolchain if configured in pom.xml)
  • BREE: use MANIFEST header Bundle-RequiredExecutionEnvironment to lookup the JDK from toolchains.xml. The value of BREE will be matched against the id of the toolchain elements in toolchains.xml.
Example for BREE:
In META-INF/MANIFEST.MF: 
Bundle-RequiredExecutionEnvironment: JavaSE-1.7
In toolchains.xml: 
<toolchains>
   <toolchain>
      <type>jdk</type>
      <provides>
         <id>JavaSE-1.7</id>
      </provides>
      <configuration>
         <jdkHome>/path/to/jdk/1.7</jdkHome>
      </configuration>
   </toolchain>
</toolchains>
