About Jacoco Advanced Training.
Understand where Jacoco fits in modern software delivery, what this level covers, and how the program builds practical confidence step by step.
Program overview
Jacoco is taught as a practical technical skill for modern engineering, operations and platform teams. The course explains where the tool fits, how it is used in real delivery environments, and how learners can apply it through guided practice.
This DevOpsSchool Jacoco program is built for working professionals who want usable skills instead of only conceptual exposure. The training emphasizes live examples, workflow clarity, operational controls and progressive skill depth from Foundation to Advanced.
Private Jacoco training for delivery teams, platform groups and engineering organizations.
DevOpsSchool provides corporate Jacoco training for teams that need faster adoption, workflow standardization, administrative control, integration guidance and governance-ready rollout. Private batches can be aligned to development practice, release workflow, access model, maturity level and internal tooling.
- Private online or classroom delivery for engineering teams
- Aligned to Jacoco usage maturity, admin depth and collaboration patterns
- Useful for rollout, migration, governance and workflow consistency goals
- Can be tailored for developers, administrators, DevOps teams and leadership stakeholders
Why teams use DevOpsSchool
DevOpsSchool combines live demonstration, practical workflow discussion, implementation-oriented examples, and strong post-session learning support. That makes the training more usable for real teams than generic slide-led courses.

Why Jacoco matters
- Jacoco helps teams standardize a critical part of their software delivery, infrastructure, automation or operations workflow.
- It gives learners a repeatable way to move from basic usage to confident execution in team and enterprise environments.
- For DevOps and platform teams, Jacoco becomes more valuable when connected with automation, governance, monitoring and delivery practices.
- Teams using Jacoco effectively reduce ad-hoc execution and move toward consistent engineering standards.
Objectives
- Understand Jacoco concepts, architecture, terminology and operational usage patterns.
- Learn practical configuration, workflow design, access controls, team usage and quality practices.
- Apply Jacoco in real delivery workflows using automation, integrations, traceability and governance patterns.
- Build practical confidence to use Jacoco for individual, team and organizational use cases.
Pre-requisites
- Basic computer literacy and familiarity with software development workflows.
- Helpful but not mandatory: introductory DevOps, cloud, automation or software delivery awareness.
- No deep programming background is required for the Foundation and Essential levels.
Who this course is for
- Developers, administrators and engineers who need practical Jacoco usage skills.
- DevOps engineers, release engineers, SREs and platform teams managing delivery standards.
- Engineering leads and technical managers responsible for workflow quality, access controls and governance.
- Corporate teams migrating to or standardizing on Jacoco.

This page shows the learning flow from Foundation through Advanced. Each level adds to the previous one, and the agenda stops at the current page level. Day counts are for corporate (day-wise) delivery; live online batches cover the same agenda in max 8 to 10 hours.
Foundation Level: Coverage concepts, JVM internals and installationDay 1
- Code coverage concepts: what coverage measures, what it cannot prove, and where it fits in a Java CI pipeline
- The rise of the virtual machine: the JVM, class files and bytecode, and why JaCoCo instruments bytecode
- Containers vs VMs for Java test runs: what containers are and how a JVM behaves inside them
- Under the hood: container isolation for the JVM, and JaCoCo probes that record executed bytecode
- JaCoCo overview: origins with EclEmma, supported Java versions, agent, command line and report components
- Coverage counters: instructions, branches, cyclomatic complexity, lines, methods and classes
- The future of JaCoCo and containers: support for new Java releases, Kotlin and containerised builds
- Installing and updating JaCoCo: latest stable 0.8.x distribution, jacocoagent.jar, jacococli.jar, plugin coordinates
- Installing JaCoCo on Ubuntu: OpenJDK, Maven and Ant setup, unpacking the distribution and verifying the CLI
- Installing JaCoCo on CentOS and RHEL-family hosts: JDK via dnf, JAVA_HOME and build tool setup
- First coverage report: run JUnit 5 tests with the agent attached and generate an HTML report
- Reading the HTML report: package, class and source views, red, yellow and green line and branch markers
Essential Level = Foundation + Agent configuration, remote collection and report formatsDay 2 · 2 days cumulative
- Updating JaCoCo: upgrading agent and plugin versions together, JDK compatibility and execution data format checks
- Granting control to non-root users: running the agent and CLI as a build user with writable output paths
- Configuring JaCoCo to communicate over the network: agent output modes file, tcpserver and tcpclient, address and port
- Dumping coverage remotely: jacococli dump against a running JVM, the reset option and session IDs
- Playing around with a first JaCoCo container: attaching the agent through JAVA_TOOL_OPTIONS in a Docker image
- Agent includes and excludes: limiting instrumentation to your own packages and skipping generated code
- Report formats: HTML for people, XML for tools such as SonarQube, CSV for scripts and spreadsheets
- Matching classes and sources: pointing reports at the exact compiled classes and source folders
- Gradle jacoco plugin: the jacocoTestReport task, report formats and test task configuration
- Unit and integration coverage: separate execution data files for Surefire and Failsafe test runs
- Filtering report noise: Lombok and other @Generated code, synthetic methods and build-level class excludes
- Hands-on session: measure a multi-class service running in a container and review coverage gaps as a team
Intermediate Level = Essential + Build tool, CI and quality gate integrationsDay 3 · 3 days cumulative
- Integrations provided by the JaCoCo project: Java API, command line, Apache Ant and Apache Maven
- Java API: ExecFileLoader, Analyzer, CoverageBuilder and report formatters for custom coverage tooling
- Command line interface: jacococli.jar commands report, merge, dump, instrument, classinfo and execinfo
- Apache Ant integration: adding the JaCoCo antlib, the taskdef namespace and wiring coverage into build.xml
