branch: emacs-29
commit 1917c51fe6881847e5e373b81d2330aa86b5b7bb
Author: F. Jason Park <jp@neverwas.me>

    ; Prevent ERC-induced false positive in JUnit report
    
    * test/lisp/erc/erc-scenarios-internal.el: Mimic other test files,
    like perl-mode-tests.el, in setting `ert-load-file-name' globally.
    This file formerly caused a false positive in the error detection
    logic of `ert-write-junit-test-summary-report'.  It affected all
    scheduled pipelines, including those for the release branch, Emacs 29.
