What steps will reproduce the bug?

$ ./configure
$ make -j4 test

will get below warning:
[----------] 19 tests from EnvironmentTest
[ RUN ] EnvironmentTest.EnvironmentWithESMLoader
(node:15120) ExperimentalWarning: VM Modules is an experimental feature. This feature could change at any time
(Use node --trace-warnings ... to show where the warning was created)

$ node --trace-warnings ...
node:internal/modules/cjs/loader:988
throw err;
^

How often does it reproduce? Is there a required condition?

Always

What is the expected behavior?

I think you're interpreting node --trace-warnings ... a bit too literally. :-)

What exactly are you trying to do? cctest is part of node's test suite, it's not something you normally run standalone.

[ArchanaWind]

I am trying to run Nodejs test suite

$make -s cctest

[bnoordhuis]

Ah, okay. Just ignore the ExperimentalWarning, it's harmless.

cctest basically contains an embedded copy of node and node of course prints a warning when you use any of the --experimental-* flags.

[ArchanaWind]

Thank you very much

[bnoordhuis]

No problem. I'll go ahead and close the issue.

Hi Ben,

make -j4 test is just building the tests, Can you please tell where I can find the executable to run tests
Thanks in advance

[bnoordhuis]

make test definitely runs the test suite, unless you have build errors.

[ArchanaWind]

I could not able to see test results for "$make -s build-addons", can you please suggest where I can find test results for build-addons

[bnoordhuis]

Try make test-addons

[ArchanaWind]

Hi Ben,

To build the tests, is node binary is required?

Thanks in advance

[bnoordhuis]

addon-tests yes, cctests no. With the exception of cctests you're going to need node to actually run any tests though.

[ArchanaWind]

Thank you for quick response
As I know to run tests, package binaries are required, My requirement is I just want to build tests not to run.
To do only build tests, Is Nodejs binary is required?

$make -j4 test -> will it do both build and run tests or will it do only build tests
my requirement is build tests on host machine and copy test binary to target and run on target

Short description on my task:
I am working on adding ptest support for Nodejs on Yocto environment
ptest is nothing but package test, I think you are aware of Yocto framework
Yocto framework is used to build customized linux distribution

The usual process ptest follows is build tests on host and run test binaries on target

[bnoordhuis]

Tests from tests/addons, test/js-native-api and test/node-api need node-gyp to build and node-gyp in turn needs node.

Rule of thumb: needs node if it has a binding.gyp file.

Got it, Thank you
