The previous approach was based on the observation that some Prow jobs use the
--report-dir parameter instead of the E2E_REPORT_DIR env variable. Parsing the
command line was necessary to use the --json-report and --junit-report
parameters.
But that is complex and can be avoided by triggering the creation of complete
reports in the E2E test suite. The paths are hard-coded and relative to the
report directory to keep the code simple.
There was a report that k8s-triage started processing more data after
6db4b741dd was merged. It's unclear whether
that was because of the new <report-dir>/ginkgo_report.xml file. To avoid
this potential problem, the reports are now in a "ginkgo" sub-directory.
While at it, error checking gets enhanced:
- Create directories at the start of
the suite and bail out early if that fails.
- *All* e2e suites using the framework do this, not just test/e2e.
- Added missing error checking of truncated JUnit report writing.
