Tycho Surefire Plugin – tycho-surefire:test

tycho-surefire:test

Full name:

org.eclipse.tycho:tycho-surefire-plugin:4.0.1:test

Description:

Executes tests in an OSGi runtime. This is only supported in modules of packaging type `eclipse-test-plugin`.

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: <bundleStartLevel> <bundle> <id>foo.bar.myplugin</id> <level>6</level> <autoStart>true</autoStart> </bundle> </bundleStartLevel>
`<classLoaderOrder>`	`AbstractEclipseTestMojo$ClassLoaderOrder`	`-`	The test runtime is configured with a composite class loader. This defines the order in which the loaders are searched, and it may need to be configured depending on the resolved classpath of the project. Available values are: `booterFirst` - the loader of the surefire booter (including bundled test platform) is searched first `testProbeFirst` - the loader of the test class's plugin is searched first Defaults to `booterFirst`. Default value is: `booterFirst`.
`<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`.

`<dependencies>`	`Dependency[]`	`-`	Additional dependencies to be added to the test runtime. 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> <extraRequirements> <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`.

`<suiteXmlFiles>`	`List<String>`	`-`	Only supported by the TestNG test provider. The values specified are passed to TestNG as test suite files. 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>
`<surefireProperties>`	`File`	`-`	(no description) Default value is: `${project.build.directory}/surefire.properties`.
`<systemProperties>`	`Map<String,String>`	`-`	Additional system properties to set for the forked test JVM.
`<test>`	`String`	`-`	Specify this parameter if you want to use the test pattern matching notation, Ant pattern matching, to select tests to run. The Ant pattern will be used to create an include pattern formatted like `/${test}.java` When used, the `includes` and `excludes` patterns parameters are ignored User property is**: `test`.
`<testClass>`	`String`	`-`	Identifies a single test (suite) class to run. This is useful if you have a single JUnit test suite class defining which tests should be executed. Will be ignored if `test` is specified. Example: <testClass>foo.bar.FooTest</testClass> User property is: `testClass`.
`<testClassesDirectory>`	`File`	`-`	The directory containing generated test classes of the project being tested. User property is: `project.build.outputDirectory`.
`<testFailureIgnore>`	`boolean`	`-`	Set this to true to ignore a failure during testing. Its use is NOT RECOMMENDED, but quite convenient on occasion. Default value is: `false`. User property is: `maven.test.failure.ignore`.
`<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: `false`. User property is: `trimStackTrace`.
`<useJDK>`	`ToolchainProvider$JDKUsage`	`-`	Which JDK to use for executing tests. Possible values are: `SYSTEM`, `BREE` . SYSTEM: Use the currently running JVM (or from toolchain if configured in pom.xml) BREE: use MANIFEST header `Bundle-RequiredExecutionEnvironment` to lookup the JDK from toolchains.xml. The value of BREE will be matched against the id of the JDK toolchain elements in `toolchains.xml`. If the BREEs version is 9 or later and the ID did not match any element, the version of the BREE will be matched against the version of the JDK toolchain elements. Example for BREE: In `META-INF/MANIFEST.MF`: Bundle-RequiredExecutionEnvironment: JavaSE-11 In toolchains.xml: <toolchains> <toolchain> <type>jdk</type> <provides> <id>JavaSE-11</id> <version>11</version> </provides> <configuration> <jdkHome>/path/to/jdk/11</jdkHome> </configuration> </toolchain> </toolchains> Default value is: `SYSTEM`.
`<useUIHarness>`	`boolean`	`-`	Run tests using UI (true) or headless (false) test harness. Default value is: `false`. User property is: `tycho.surefire.useUIHarness`.
`<useUIThread>`	`boolean`	`-`	Run tests in UI (true) or background (false) thread. Only applies to UI test harness. Default value is: `true`. User property is: `tycho.surefire.useUIThread`.
`<useUnlimitedThreads>`	`boolean`	`0.16.0`	(JUnit 4.7 provider) Indicates that the thread pool will be unlimited. The parallel parameter and the actual number of classes/methods will decide. Setting this to "true" effectively disables perCoreThreadCount and threadCount. Default value is: `false`. User property is: `useUnlimitedThreads`.
`<work>`	`File`	`-`	Root directory (osgi.install.area) of the Equinox runtime used to execute tests. Default value is: `${project.build.directory}/work`.

Set this to true to ignore a failure during testing. Its use is NOT RECOMMENDED, but quite convenient on occasion.

Type: boolean
Required: No
User Property: maven.test.failure.ignore
Default: false

<testRuntime>

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>

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: false

<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 JDK toolchain elements in toolchains.xml. If the BREEs version is 9 or later and the ID did not match any element, the version of the BREE will be matched against the version of the JDK toolchain elements.

Example for BREE:
In META-INF/MANIFEST.MF:

Bundle-RequiredExecutionEnvironment: JavaSE-11

In toolchains.xml:

<toolchains>
  <toolchain>
     <type>jdk</type>
     <provides>
         <id>JavaSE-11</id>
         <version>11</version>
     </provides>
     <configuration>
        <jdkHome>/path/to/jdk/11</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
User Property: tycho.surefire.useUIHarness
Default: false

<useUIThread>

Run tests in UI (true) or background (false) thread. Only applies to UI test harness.

Type: boolean
Required: No
User Property: tycho.surefire.useUIThread
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
