Creating a Session ID

Before running the build scan and tests, you need to create a session ID. The session ID is provided to each step in order to link them together as one complete cycle.

Generating a session ID in Java is done using the Java Build scanner with the -config flag. This command can be executed as an ANT Java task.

In the following sample, we have used a timestamp for the build name but any environment variable can be used according to your organization’s naming convention.

Code Block
languagexml
<tstamp>
     <format property="time.stamp" pattern="yyyyMMdd-HHmm"/>
</tstamp>

<target name="sealights_config">
	<java jar="${sealights.dir}/sl-build-scanner.jar" fork="true">
		<arg value="-config"/>
		<arg value="-tokenfile"/>
		<arg value="${sealights.dir}/sltoken.txt"/>
		<arg value="-appname"/>
		<arg value="myApp"/>
		<arg value="-branchname"/>
		<arg value="master"/>
		<arg value="-buildname"/>
		<arg value="${time.stamp}"/>
		<arg value="-pi"/>
		<arg value="*com.company.*"/>
	</java>
</target>

In the sample code above, we have used a timestamp for the build name but any environment variable can be used according to your organization’s naming convention.

In order to capture code coverage information from tests run with JUnit, you need to run it with our test listener as a Java agent:.

JUnit 4.x

  • The listener needs to be passed using the jvmarg attribute -javaagent parameter together with its required parameters.

JUnit 4.x

...

  • .

Code Block
languagexml
<junit fork="yes">
  <jvmarg value="-javaagent:${sealights.dir}/sl-test-listener.jar"/>
  <jvmarg value="-Dsl.tokenFile=${sealights.dir}/sltoken.txt"/>
  <jvmarg value="-Dsl.buildSessionIdFile=buildSessionId.txt"/>
  <jvmarg value="-Dsl.testStage=Unit Tests"/>
</junit>

JUnit 5.x

  1. When tests are running in the same process, the listener needs to be passed using the jvmarg attribute -javaagent parameter with Sealights' Anonymous Execution mode deactivated.

  2. When tests are running in a different process (via a fork), we need to add the start and end commands before and after tests execution

Same process (not forked)

Different process (forked)
