Testing Report

Date: 2026-05-08

What Was Tested

• BinaryWriter and BinaryReader primitive reads and writes, strings, magic bytes, versions, primitive arrays, bounds checks, and round trips.
• Endianness behavior and explicit byte-order handling.
• MappedBinaryReader behavior for memory-mapped file reads.
• Rinha-shaped synthetic dataset reading and writing.
• Optional full Rinha dataset tests were discovered but skipped because RINHA_DATASET_DIR was not set.
• Project sanity checks for Java 17 compilation, jar/source/javadoc artifacts, Javadocs, zero compile-scope production dependencies, and benchmark profile wiring.

Commands Run

mvn -B clean verify
mvn -B test jacoco:report
mvn -B javadoc:javadoc
mvn -B dependency:list -DincludeScope=compile
mvn -B -Pspotbugs -DskipTests verify
mvn -B -Pdependency-check -Ddependency-check.skip=true -DskipTests verify
mvn -B -Pbenchmarks test-compile
mvn -B -Prinha-benchmark test-compile

Results:

• mvn -B clean verify: passing, 120 tests, 0 failures, 0 errors, 6 skipped full-dataset tests.
• mvn -B test jacoco:report: passing; reports generated at target/site/jacoco/jacoco.xml and target/site/jacoco/index.html.
• mvn -B javadoc:javadoc: passing.
• mvn -B dependency:list -DincludeScope=compile: passing, no compile-scope production dependencies beyond the project artifact.
• mvn -B -Pspotbugs -DskipTests verify: passing profile validation.
• mvn -B -Pdependency-check -Ddependency-check.skip=true -DskipTests verify: passing profile validation with Dependency-Check database scanning intentionally skipped.
• mvn -B -Pbenchmarks test-compile: passing.
• mvn -B -Prinha-benchmark test-compile: passing.

Known Limits

• Full Rinha dataset validation requires setting RINHA_DATASET_DIR to a local dataset path.
• Benchmark profiles were compile-checked only; long JMH benchmark runs were not executed during this pass.
• The report records automated verification only and does not replace the release workflow.

Future Tests Recommended

• Run full Rinha dataset verification with a pinned dataset revision.
• Record fresh JMH results with hardware, JDK, warmup, and dataset details.
• Add more corrupted-header and truncated-file fixtures.
