Slice & Dice

Automation and the “3 layer cake”
TestKitGen (TKG)
Test Results Summary Service (TRSS)
CI System (Jenkins / Tekton / AzDO / Github Actions, etc.)
Responsibilities:
- Categorize logically, Generates test targets based on playlist (level/platform/version/impl specific)
- Execute tests via common command line / make target patterns
- Test addition via auto-discovered directories, Standardize exclusion
- Parameters: BUILD_LIST, EXTRA_OPTIONS, JVM_OPTIONS, TEST_FLAG, ITERATION
- Generate dynamic test playlists based on input (smart parallelization)
Responsibilities:
- Schedule regular builds
- Multiplex tests across multiple nodes of all platforms
- Basic GUI view of test results
- Basic forms of parallelization
Responsibilities:
- Monitor multiple CI servers
- Graphical, Aggregate summary, Deep history
- Search/sort/filter
- Pluggable parsers
- Basis for deeper analytics and deep learning services
Layer 1: Standalone
- Standardized test execution, exclusion, reporting (TAP)
- Overlay additional tests
- Single code base for multi-version
- Reproducibility
- Parallel modes
Layer 2: Requires L1
- Multiplex across more nodes/platforms
- Scheduling
- Basic GUI
- Enhanced granularity for test results in JUnit format
Layer 3: Requires L1 & L2
- Database queries
- Search/sort/filter/analyze across DB entries
- Monitor anything
- Basis for extras

Layer 1: TKG
• Demo - Basic local execution • Fetch test definitions & materials
• git clone aqa-tests
• get.sh (to fetch materials)
• Tell TKG what to compile & test
• export BUILD_LIST=openjdk,system
• export TEST_JDK_HOME=$SUT
• Compile test material
• make compile
• Run tests
• make _test_target

Layer 2: CI with Jenkins
• Grinder
• Grinder PARALLEL=Dynamic

Layer 2: CI with Github Actions
• Demo
• setup-java
• install-jdk
• build-jdk
• build-openj9
• run-aqa

• Test Category:
• openjdk, functional, external, system, etc
• Test JDK:
• JDK built by GitHub action: build-jdk, build-openj9
• Installed JDK: Adoptium EA, GA, zulu Openjdk, https

Layer 3: TRSS
• Demo - API, Grid view
• Demo - Triage helpers, “the Big Four”
• Across platforms
• Deep history
• Possible issues
• Raise an issue
• Release Triage report
• Performance views

2021 AQAvit Program Plan
• AQAvit quality mark & Adoptium marketplace
• Enhancements
• External tests (Tweetest)
• Performance benchmarks
• ML on results (Deep AQAtik)
