All reports of pkg-js-tools-test-is-missing for the archive. The extended description of this tag is:
The debian/rules file for this package uses --with nodejs which attempts to execute the specified file when running autopkgtests.
When this file is missing, only a simple node require(".") is launched which may be insufficient to really test this nodejs module.
Please specify the upstream testsuite (or a custom one) in debian/tests/pkg-js/test (see /usr/share/doc/pkg-js-tools/README.md.gz).
This tag has not been emitted in any package tested by Lintian.
