Jest Example fails on Windows聽#1454
Description
Activity
I suspect you need to copy jest.config.js to the output folder and then reference that copy.
See https://github.com/bazelbuild/rules_nodejs/blob/master/docs/Built-ins.md#copy_to_bin
Hello
I got the same error, on windows trying to run jest tests.
So I tried to add
copy_to_binas you suggested @alexeagle but after some digging I found that jest is executed inC:\users\$USER\_bazel_$USER\u3lrkeg4\execroot\<workspace-name>\bazel-out\x64_windows-fastbuild\bin\test.bat.runfiles\<workspace-name>which is empty.The directory
C:\users\$USER\_bazel_$USER\u3lrkeg4\execroot\<workspace-name>\bazel-out\x64_windows-fastbuild\bin\seems well populated.I found in the source, there is a comment about Windows
https://github.com/bazelbuild/rules_nodejs/blob/master/examples/jest/BUILD.bazel#L14
So I tried to add this argument and ran
bazel test test --enable_runfiles. Then I get another errorINFO: Invocation ID: edecd830-ef9a-4fca-adc0-a20e5c3f1b25 INFO: Analyzed target //:test (503 packages loaded, 10582 targets configured).

Reacted by Lukas Holzer@alexeagle When I go the folder
examples/jestin the rules_nodejs (stable branch) and runningbazel run :testit is working fine on macOS and Linux but on windows, it is failing with:
I think I found somehow the issue:
If I run
bazel run //:testit will fail with the above errorIf I rerun
bazel run //:test --enable_runfileswith the enable_runfiles flag It will fail differently with:ERROR: Manifest file c:\Users\ADMINI~1\_BAZEL~1\rgyky3dz\execroot\EXAMPL~1\bazel-out\x64_windows-fastbuild\bin\test.bat.runfiles\examples_jest\test.bat.runfiles_manifest does not exist.And When I run now the first command without the runfiles flag it will pass
bazel run //:test
After a
bazel cleanThe first issue withCan't find a root directory while resolving a config file path.occurs again.Addition:
When I run it with verbose logs you can see that in the failing case it uses the
module_mappings.jsonfrom a different location. This is the only difference I can see with--define=VERBOSE_LOGS=1Failing:
