Built by Maven

tycho-surefire:integration-test

Full name:

org.eclipse.tycho:tycho-surefire-plugin:3.0.4:integration-test

Description:

Executes integration-tests in an OSGi runtime.

The goal launches an OSGi runtime and executes the project's integration-tests (default patterns are PluginTest*.class, *IT.class) 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.

This goal adopts the maven-failsafe paradigm, that works in the following way:

  1. pre-integration-test phase could be used to prepare any prerequisite (e.g. starting web-server, files, ...)
  2. integration-test phase does not fail the build if there are test failures but a summary file is written
  3. post-integration-test could be used to cleanup/tear down any resources from the pre-integration-test phase
  4. test outcome is checked in the verify phase that might fail the build if there are test failures

summary files are generated according to the default maven-surefire-plugin for integration with tools that already work with maven-surefire-plugin (e.g. CI servers)

Attributes:

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

Required Parameters

Name Type Since Description
<reportDirectory> File - (no description)
Default value is: ${project.build.directory}/failsafe-reports.
<summaryFile> File - (no description)
Default value is: ${project.build.directory}/failsafe-reports/failsafe-summary.xml.

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>
               <type>eclipse-feature</type>
               <id>example.project.feature</id>
               <versionRange>0.0.0</versionRange>
            </requirement>
         </extraRequirements>
      </dependency-resolution>
   </configuration>
</plugin>
The dependencies specified as extraRequirements are – together with the dependencies specified in the MANIFEST.MF of the project – transitively resolved against the target platform. The resulting set of bundles is included in the test runtime.
<enableAssertions> boolean 1.5.0 By default, Tycho Surefire disables JVM assertions for the execution of your test cases. To enable the assertions, set this flag to "true".
Default value is: false.
User property is: enableAssertions.
<environmentVariables> Map<String,String> - Additional environments to set for the forked test JVM.
<excludedGroups> String - (junit47 provider with JUnit4.8+ only) Excluded groups/categories (comma-separated). Any methods/classes/etc with one of the groups/categories specified in this list will specifically not be run. For JUnit, this parameter forces the use of the junit47 provider

<providerHint> String 0.16.0 Normally tycho will automatically determine the test framework provider based on the test project's classpath. Use this to force using a test framework provider implementation with the given role hint. Tycho comes with providers "junit3","junit4","junit47","junit5". Note that when specifying a providerHint, you have to make sure the provider is actually available in the dependencies of tycho-surefire-plugin.
<providerProperties> Properties 0.16.0 Use this to specify surefire provider-specific properties.
<reactorConcurrencyLevel> int - Configures the overall concurrency level. Important Note: If there are multiple mojo configurations this will choose the lowest configured number! So for example if in the same reactor there is one configuration with a concurrency level of 5 and one with a concurrency level of 3 then then only three parallel runs will be possible!

The suite files will overwrite the includes and excludes patterns. The path to the suite file(s) could be relative (test bundle classpath) or an absolute path to xml files outside the test bundle. 
<configuration>
  <suiteXmlFiles>
    <suiteXmlFile>myTestSuite.xml</suiteXmlFile>
  </suiteXmlFiles>
</configuration>

User property is: testClass.
<testClassesDirectory> File - The directory containing generated test classes of the project being tested.
User property is: project.build.testOutputDirectory.
<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.

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>
  • Type: java.lang.String
  • Since: 0.19.0
  • Required: No
  • Default: default

<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
  • Since: 1.3.0
  • 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>
  • Type: org.eclipse.tycho.core.maven.ToolchainProvider$JDKUsage
  • Required: No
  • Default: SYSTEM

<useUIHarness>

Run tests using UI (true) or headless (false) test harness.
  • Type: boolean
  • Required: No
  • Default: false

<useUIThread>

Run tests in UI (true) or background (false) thread. Only applies to UI test harness.
  • Type: boolean
  • Required: No
  • Default: true

<useUnlimitedThreads>

(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.
  • Type: boolean
  • Since: 0.16.0
  • Required: No
  • User Property: useUnlimitedThreads
  • Default: false

<work>

Root directory (osgi.install.area) of the Equinox runtime used to execute tests.
  • Type: java.io.File
  • Required: No
  • Default: ${project.build.directory}/work
