cannot load such file -- pact/mock_service/request_handlers/base_administration_request_handler

[Christoph-Raab]

Software versions

• Windows 10.0.18362 Build 18362
• @pact-foundation/pact: 9.5.0
• jest: 24.9.0
• Node Version v10.15.3
• npm Version: 6.4.1

Expected behaviour

Contract tests run with jest

Actual behaviour

The project is setup like this:
https://github.com/pact-foundation/pact-js/tree/master/examples/jest

On running:
jest --runInBand --setupFiles ./pact/pactSetup.js --setupTestFrameworkScriptFile=./pact/pactTestWrapper.js

I get the error message (see detailed log below):
cannot load such file -- pact/mock_service/request_handlers/base_administration_request_handler (LoadError)

Afterwards the test suite fails because:
TypeError: Cannot read property 'writePact' of undefined

[INFO] 
[INFO]       3 | beforeAll(() => provider.setup())
[INFO]       4 | 
[INFO]     > 5 | afterAll(() => provider.finalize())
[INFO]         |                         ^
[INFO]       6 | 

I am aware of this issue:
#100,

but enabling long path did nothing.

Steps to reproduce

I am running the build inside the https://github.com/eirslett/frontend-maven-plugin and call the npm run test commant like this:

<execution>
    <id>npm build</id>
    <goals>
        <goal>npm</goal>
    </goals>
   <phase>generate-resources</phase>
  <configuration>
      <arguments>run test</arguments>
  </configuration>
</execution>

This works in principle, since I can run other tests with jest with this command. For testing, all other tests are disabled, I only run the contract test.

When I delete the node_modules folder and run within wsl2:

• npm install
• npm run test

This works. It's only inside the frontend-maven-plugin.
Inside the frontend-maven-plugin runs the npm install command, which downloads the binaries for win32:

Installing Pact Standalone Binary for win32.
[INFO] Downloading Pact Standalone Binary v1.72.2 for platform win32 from https://github.com/pact-foundation/pact-ruby-standalone/releases/download/v1.72.2/pact-1.72.2-win32.zip

When I browse to pact/mock_service/request_handlers inside node_module, there is a base_administration_request_handler.rb file

Any ideas?

Can you try building the project in a shallower path? (this will help confirm that it is indeed the long path issue).

[Christoph-Raab]

I set up a project in C:\testd, instead of now it works.

Also I counted letters of the original path, it is more than 263.

I also figured, that I might have to enable longPaths in the Admin Templates of Computer Configuration as mentioned here:
https://stackoverflow.com/questions/27680647/does-max-path-issue-still-exists-in-windows-10

I did that, but it still doesn't work.

Any other ideas?

If it is indeed the 'too long path' issue, we don't have a fix at the moment I'm afraid. We are working on an alternative to the pact-ruby-standalone, however, we don't have an expected finish date yet.

Use a Linux VM? Or Docker?

Ok, thanks, that's bad.

I would have to set this up and everyone in my team. Bit much overhead just to use a dependency.

But ok, than I guess I have to rethink and/or wait for the release of the new standalone

In my case the path of the project under windows was just too long. To solv this i had to copy the project to a directory which wasnt that much nested as before (i.e. C:\myproject).
