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 (debian/nodejs/extlinks)
• if additional modules were copies during build, they will be copied into
node_module (debian/nodejs/extcopies)
• 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 "require('.')". 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 /usr/share/nodejs/<module-name>/package.json):
• 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 @types/<foo> modules)
• else it simply launches a nodejs -e "require('$moduleName')"
Since version 0.10.0, pkg-js-autopkgtest does the same test for all other
modules installed in nodejs root directories (components installed by
dh-sequence-nodejs using debian/nodejs/root_modules 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.
