What it reads

The viewer reads JUnit style XML from Maven Surefire, Gradle, pytest, jest-junit and similar runners, including nested testsuite elements and Surefire rerun elements, plus xunit.net v2 XML. Each test case gets one status: error, failed, skipped or passed, in that order of priority.

How totals are counted

Totals are counted from the test cases themselves, not from the tests and failures attributes on the suite, because those attributes are sometimes stale. The pass rate leaves skipped tests out. Times that are not plain decimal seconds are counted as invalid and left out of the total time.

Limits

Reports declaring custom XML entities are rejected. Very large system-out blocks count toward the character limit. The tool does not run tests; it only reads the report you supply.
