@Peefy When I run make test on the main branch of the project, I see the following test failures:

failures:
    completion::tests::complete_unimport_schemas
    completion::tests::import_external_pkg_test
    completion::tests::var_completion_test
    hover::tests::assignment_ty_in_lambda_hover

    tests::test_lsp_with_kcl_mod_in_order

test result: FAILED. 157 passed; 23 failed; 0 ignored; 0 measured; 0 filtered out; finished in 15.02s

Even after running the tests on the branch with my changes, these tests are still failing, and the new test I added also fails. Could this be an issue with my setup, or is there another reason for these failures? Any guidance would be greatly appreciated!

I see that one of the tests in the CI failed. When I run the tests in my local machine, several of them are still failing (most of them are bench mark tests and failing because of that) including the one which failed here. The output for the konfig_hover_test_main when I run it individually is:

running 1 test
test tests::konfig_hover_test_main ... FAILED

I looked at the CI's output for the failed test and added the missing Examples doc to the test and still got the same output I attached above.
Also, I couldn't locate the main.k file for the test, is is generated via code?

Hello @Siddhi-agg This is a git submodule. You can update the submodule to get test cases.

@Peefy @zong-zhe @He1pa PTAL
Would you like me to add something more to this?
