Well it was a fight but got the code coverage working with VS Code \/ Java and Coverage Gutters extension. Doing this for an exercise under preparation for the next Fall course on Data Structures and Algorithms. Probably this is just a demo or something students may take a look at, not a required task.<\/p>\n\n\n\n

Code coverage visible, YEAH!!<\/figcaption><\/figure>\n\n\n\n

What I have in the Maven pom.xml<\/code> currently is <\/p>\n\n\n\n

<argLine>-Xmx2048m<\/argLine><\/pre>\n\n\n\n
within the properties<\/code> struct, and in the build\/plugins<\/code>:<\/p>\n\n\n\n
<plugin>\n   <artifactId>maven-failsafe-plugin<\/artifactId>  \n   <version>2.22.2<\/version>\n      <configuration>\n        <argLine>${argLine} -Xmx4096m -XX:MaxPermSize=512M ${itCoverageAgent}<\/argLine>\n      <\/configuration>\n<\/plugin><\/code><\/pre>\n\n\n\n
and the whole jacoco plugin structure is here, under the build\/plugins<\/code> structure (with some commented out sections):<\/p>\n\n\n\n
<plugin>\n    <groupId>org.jacoco<\/groupId>\n    <artifactId>jacoco-maven-plugin<\/artifactId>\n    <version>0.8.8<\/version>\n    <executions>\n        <execution>\n            <id>pre-unit-test<\/id>\n            <goals>\n                <goal>prepare-agent<\/goal>\n            <\/goals>\n            <configuration>\n                <!-- Sets the path to the file which contains the execution data. -->\n                <dataFile>${project.build.directory}\/jacoco.exec<\/dataFile>\n                <outputDirectory>${project.reporting.outputDirectory}\/jacoco<\/outputDirectory>\n                <propertyName>surefireArgLine<\/propertyName>\n            <\/configuration>\n        <\/execution>\n        <!-- Ensures that the code coverage report for unit tests is created \n              after unit tests have been run. -->\n        <execution>\n            <id>post-unit-test<\/id>\n            <phase>test<\/phase>\n            <goals>\n                <goal>report<\/goal>\n            <\/goals>\n            <configuration>\n                <!-- Sets the path to the file which contains the execution data. -->\n                <dataFile>${sonar.jacoco.reportPath}<\/dataFile>\n                <!-- Sets the output directory for the code coverage report. -->\n                <outputDirectory>${jacoco.path}<\/outputDirectory>\n            <\/configuration>\n        <\/execution>\n        <execution>\n            <id>default-report<\/id>\n            <goals><\/goals>\n            <configuration>\n                <dataFile>${project.build.directory}\/jacoco.xml<\/dataFile>\n                <outputDirectory>${project.reporting.outputDirectory}\/jacoco<\/outputDirectory>\n            <\/configuration>\n        <\/execution>\n        <execution>\n            <id>jacoco-check<\/id>\n            <goals>\n                <goal>check<\/goal>\n            <\/goals>\n            <configuration>\n                <rules>\n                    <rule>\n                        <element>PACKAGE<\/element>\n                        <limits>\n                            <limit>\n                                <counter>LINE<\/counter>\n                                <value>COVEREDRATIO<\/value>\n                                <minimum>0.0<\/minimum>\n                            <\/limit>\n                        <\/limits>\n                    <\/rule>\n                <\/rules>\n            <\/configuration>\n        <\/execution>\n    <\/executions>\n<\/plugin><\/code><\/pre>\n\n\n\n
and finally, you need to build from the command line with this Maven command:<\/p>\n\n\n\n
mvn jacoco:prepare-agent package jacoco:report<\/code><\/pre>\n\n\n\n
So when viewing the code then, you can see the code coverage colors in the code editor sidebar on the left.<\/p>\n","protected":false},"excerpt":{"rendered":"
