Unreleased

0.1.0 - 2026-09-22

Initial release of lein-junit-xml.

Reporting

• lein junit-xml runs the project's tests and writes JUnit legacy XML. One TEST-<namespace>.xml file per test namespace, matching the element and attribute set JUnit 6.2.0's own report writer emits.
• Suite-level <system-out> and <system-err> capture, covering output from :once and :each fixtures as well as test bodies.
• Selector-excluded tests are reported as <skipped> rather than silently vanishing, so CI totals stay honest.
• A throwing :once fixture is reported as an initializationError case instead of producing an empty, green suite.

Correctness

• One character policy for every string entering a document. Characters outside XML 1.0's Char production (including ANSI escapes, control bytes, non-characters, and unpaired surrogates) are replaced; ]]> inside CDATA is split; attribute whitespace is escaped numerically.
• Documents are rendered whole and written once, so no failure mid-run can leave a truncated file with an unclosed root element.
• Reporting errors never change the outcome of a test run. Every entry point catches and reports rather than propagating.
• time is formatted with Locale/ROOT, so a comma-decimal default locale cannot be misread by Jenkins as a thousand separator.
• timestamp is an explicit UTC instant, deviating from JUnit's zone-less local time, which Jenkins misinterprets as UTC.

Compatibility

• lein test is left intact. The task delegates to leiningen.test/test, so selectors, :test-paths, exit codes and .lein-failures (and therefore lein retest) keep working.
• Custom clojure.test/report methods keep working, because the plugin adds delegating methods rather than replacing the multimethod.
• Verified against jenkins-junit.xsd in CI, and against the Jenkins JUnit plugin 1428.vef95b_fa_89508 parser.
• Requires Leiningen 2.10.0+, Clojure 1.9+ and Java 8+. These are measured rather than assumed: every floor was established by running the plugin, and CI exercises the oldest Clojure on the oldest Java. See the reference for the evidence, including why the advertised Leiningen floor is higher than the oldest version observed to work.

Configuration

• :junit-xml {:output-dir "target/junit-xml"}. Unknown keys are rejected rather than ignored.

Dependencies

• None. Clojure and the JDK only.
