@NiketaPopatChaudhari can you please add a validate for version 20 here:

• serverless-azure-functions/.github/workflows/validate.yml

  Line 11 in c9103a7

  version: [12, 14, 16, 18]

and integration for version 20 in 2 places:

• serverless-azure-functions/.github/workflows/integration.yml

  Line 13 in c9103a7

  node-version: [12, 14, 16, 18]

• serverless-azure-functions/.github/workflows/integration.yml

  Line 76 in c9103a7

  node-version: [12, 14, 16, 18]

[NiketaPopatChaudhari]

@NiketaPopatChaudhari looks like validate failed for node 20, can you please have a look, the failures can be found here https://github.com/serverless/serverless-azure-functions/actions/runs/8715495822/job/23909330268?pr=683

Looking into @gligorkot

[gligorkot]

@NiketaPopatChaudhari you can try run the tests locally

[NiketaPopatChaudhari]

yes @gligorkot i am testing it on local and working on it to fix UT

[NiketaPopatChaudhari]

@gligorkot have tested on local with master branch Observation as below

Node Version 18.20.2 without any changes on the master branch

Node Version 20.12.1 without any changes on the master branch

[gligorkot]

@NiketaPopatChaudhari make sure you have cleared node_modules and re-installed them when running with node 18.

When I run node 18.20.2, all tests pass on the master branch for me:

However when I run using node 20.12.2 some of them do fail - can you please investigate what fails and what we need to do to fix these?

Hey @gligorkot, @NiketaPopatChaudhari

I tried executing Tests (with Node Version: 20.12.2) in master branch (Without any changes) and it still fails in 27 cases.
After having some research I could find out that its the test case code which is creating the issue here:

Most/Almost All of the failed cases are related to Mock FS module. Mock FS is already having Open issue with Node 20.
Ref: tschaub/mock-fs#384

We can try to change MockFs to MemFs but it will take some time to make these changes.

[gligorkot]

Hey @yashGanatraHK, thank you for looking into this issue. I'd first look at if removing mock-fs altogether is a viable approach, and failing that, yes updating to memfs would be my second choice.

[NiketaPopatChaudhari]

@gligorkot Have replaced all mockFs with memfs and made some additional changes now fail test count as below

@gligorkot Have replaced all mockFs with memfs and made some additional changes now fail test count as below

Thanks for keeping me in the loop @NiketaPopatChaudhari. Could you please have a look at what else needs changing to fix the remaining tests?
