Hi all,
New coverage implementation using Jacoco has been committed to master
branch of carbon-platform-integration. I tried my best to adhere to
existing Emma based design and reuse same instrumentation and filters text
files. Note that this new coverage implementation was done to support for
JDK 1.7 and 1.8. We need to test the new implementation thoroughly before
the release.
I've done initial testing with AS and everything seems to work. Automation
team will start verifying coverage with products already migrated JDK 1.7.
Specially products with multiple test modules (ESB, G-Reg & BPS)
Lets focus on testing following scenarios before the release.
Test Scenarios for coverage :
1. Coverage generation with patches applied.
2. Merge coverage reports in multiple test modules.
3. WebApp class coverage.
4. Coverage generation after restart and impact to coverage numbers.
To get started with Jacoco coverage :
1. Edit your test module pom and replace emma copy dependency execution
configuration with below.
<execution>
<id>copy-emma-dependencies</id>
<phase>compile</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>${project.build.directory}/emma</outputDirectory>
<includeTypes>jar</includeTypes>
<includeArtifactIds>emma
</includeArtifactIds>
</configuration>
</execution>
2. Include jacoco argent as a dependency to root pom.
<dependency>
<groupId>org.jacoco</groupId>
<artifactId>org.jacoco.agent</artifactId>
<version>${jacoco.agent.version}</version>
</dependency>
<jacoco.agent.version>0.7.4.201502262128</jacoco.agent.version>
3. Remove following system properties from surefire plugin.
<emma.home>${basedir}/target/emma</emma.home>
<emma.output>${basedir}/target/emma</emma.output>
You will find following log entries in console with required details to
view the report once coverage generation completed. Available report
formats are XML, HTML and CSV
