v2.6 ERT test failures on wiki-link-rules and wiki-link-search-under-project with Emacs 29.1

I cannot reproduce the issue. I think this could be your environment issue. So please ignore the results.

• org-roam/org-roam#1364

It looks like I can reproduce the test failure using both Emacs 28.2 from Debian Bookworm (stable) or Emacs 29.1 from Debian Sid (unstable). May I ask what your environment setting is like?

Also regarding the org-roam issue, the tests is done directly using emacs without any daemon mode involved, so I think it's probably unrelated.

I tested following Emacs on Desktop Ubuntu and Server Ubuntu but I cannot reproduce this issue on every Emacs

• Ubuntu Emacs 29.1 package
• non GUI Emacs built from source with ./configure --with-modules --with-json --with-sqlite3 --without-x --with-tree-sitter
• GUI Emacs built from source with ./configure --with-json --with-modules --with-tree-sitter

After some debugging, it turns out that default-directory may become empty during the run which broke the tests that relies on its value for project root detection. Setting project-current-directory-override at the beginning of the ERT tests works around this issue (the fix is at [1] if anyone is interested).

As this issue is specific to the build environment and a workaround exists, I'm closing this.
