All reports of pkg-js-autopkgtest-test-is-missing for the archive. The extended description of this tag is:
The Testsuite: field for this package points to autopkgtest-pkg-nodejs which attempts to execute the specified file during autopkgtests.
When this file is missing, only a simple node require("<module name>") is launched. This may be insufficient to really test this nodejs module (see /usr/share/doc/pkg-js-autopkgtest/README.md).
This tag has not been emitted in any package tested by Lintian.
