PKG-JS-AUTOPKGTEST(7)

NAME
pkg-js-autopkgtest - autopkgtest runner to automatically test Node.js packages

SYNOPSIS

    •   in debian/control, insert "Testsuite: autopkgtest-pkg-nodejs"

    •   write upstream test in debian/tests/pkg-js/test (will be launched by
        sh -e)

    •   if some other files than "test*" and "debian/tests/test_modules/*"
        and installed files are needed, write a "debian/tests/pkg-js/files" with
        all needed directories/files

That's all, other debian/tests files will be written on-the-fly by
autodep8 during autopkgtest

If you want to launch the same test during build, simply add
dh-sequence-nodejs in build dependencies

HOW IT WORKS

    •   if directory debian/tests/test_modules exists, NODE_PATH will be set
        to NODE_PATH=debian/tests/test_modules:node_modules

    •   if additional modules were linked during build, they will be linked into
        node_module (\fBdebian/nodejs/extlinks\fP)

    •   if additional modules were copies during build, they will be copied into
        node_module (\fBdebian/nodejs/extcopies\fP)

    •   if package contains some other components, they will be linked into
        node_module

    •   autopkgtest will launch 2 tests:

        •   a "require" test (see below)

        •   the test defined in debian/tests/pkg-js/test in a temporary dir (it
            links installed files)

    •   if dh-sequence-nodejs is a build dependency, dh_auto_test will
        launch the same test (debian/tests/pkg\-js/test) if exists, else just a
        node -e &quot;require(&#39;.&#39;)&quot;. Note that you can override test during build
        using debian/nodejs/test

    •   if file debian/tests/pkg-js/require-name exists, its content will be used
        as module name in "require" test (instead of using package\.json value)

FULL EXAMPLE

    •   debian/control
    ...
    Testsuite: autopkgtest-pkg-nodejs
    Build-Depends: dh-sequence-nodejs
    ...

    •   debian/tests/pkg-js/test
    mocha -R spec

ADDITIONAL TEST PACKAGES OR TEST RESTRICTIONS

autodep8 allows one to add additional packages during autopkgtest (and/or
additional restrictions) by using a debian/tests/autopkgtest-pkg-nodejs.conf
file:
    extra_depends=mocha, npm
    extra-restrictions=needs-internet

ENABLE proto

Since version 0.15.0, pkg-js-autopkgtest launches Node.js with
--disable-proto=throw. This causes tests to fail if
Object.prototype.__proto__ property is used.

If a package can use this feature without security hole (for test for example),
it is possible to disable this nodejs option by creating an empty
debian/tests/pkg-js/enable_proto file, until Debian's Node.js enables this
feature by default.

THE REQUIRE TEST

  How it works

First, pkg\-js\-autopkgtest searches the module name.

    •   if debian/tests/pkg-js/require-name exists, its content will be used as
        module name

    •   else if looks at package.json "name" field:

        •   if debian/nodejs/main exists, like dh\-sequence\-nodejs, it uses the
            package.json from this directory

        •   else it uses ./package.json

Then pkg\-js\-autopkgtest looks at package.json fields, not using the file
mentioned above, but using the file installed by the Debian package to test
(ie \fB/usr/share/nodejs/<module\-name>/package\.json\fP):

    •   if type equals module, then:

        •   it builds a node_modules directory with all available dependencies of
            the module

        •   it builds a test.mjs file that tries to import the module to test and
            launch it

    •   if main isn't defined and index.js doesn't exist, it skip the test
        (this avoids to try to test \fB@types/<foo>\fP modules)

    •   else it simply launches a nodejs -e &quot;require(&#39;$moduleName&#39;)&quot;

Since version 0.10.0, pkg\-js\-autopkgtest does the same test for all other
modules installed in nodejs root directories (components installed by .br dh\-sequence\-nodejs using \fBdebian/nodejs/root_modules\fP file). If one fail, the
whole test is marked as failed.

Returned values:

    •   0 if all tests succeed (even if some secondary modules are skipped)

    •   77 if all tests succeed but the main module test was skipped. This value
        is used by autopkgtest to report a SKIP instead of a failure.

    •   else, the number of failure. Then autopkgtest considers the test as FAIL

  Customize require test

If you want to skip some secondary module tests, simply list them in
debian/tests/pkg-js/require-SKIP (one module per line).

If you want to skip the whole "require" test, use this:
    echo require > debian/tests/pkg-js/SKIP

THE MAIN TEST

pkg\-js\-autopkgtest uses the same test than dh\-sequence\-nodejs: it
launches sh -ex debian/tests/pkg-js/test but using the files installed by
the Debian package.

  How main test works

pkg\-js\-autopkgtest search for module name using the same way than "require"
test. Then it prepares the test environment:

    •   it creates a temporary directory

    •   it links all files installed in the directory corresponding to module name
        /usr/share/nodejs/<module-name>

    •   it creates a node_modules directory and links into it:

        •   all modules listed in debian/nodejs/extlinks

        •   all modules present in debian/build_modules and debian/tests/test_modules

        •   all other modules installed by the Debian package in nodejs root directories
            debian/nodejs/root_modules

    •   it copies in node_modules directory all modules listed in
        debian/nodejs/extcopies

    •   if looks at debian/tests/pkg-js/files

        •   if it exists, it copies all files/directories listed in it from source
            directory to temporary one

        •   else it copies from source directory to temporary one:

            •   all test* files

            •   all Makefile like files (rollup\.config\.js, gulpfile\.js,\.\.\. )

Then it changes its directory to the temporary one launches the test using
sh -ex debian/tests/pkg-js/test.
