Test doesn't reload automatically

[lexuzieel]

Hey everyone, this is a follow-up to my question https://github.com/orgs/adonisjs/discussions/4910 where on further inspection I noticed that I also don't get automatic test reruns.

Context:

I run Japa tests using npm run test or node ace test --watch and expect tests to reload once I update the files, however this doesn't happen.

In particular, I've noticed that the process doesn't exit unless I press Ctrl+C or exit the terminal (so I guess it tries to watch the files?)

Here is the output I get:

[ info ] booting application to run tests...

unit / Project Model (tests/unit/project.spec.ts)
  ✔ create project with UUID (83.19ms)

 PASSED 

Tests  1 passed (1)
 Time  104ms

after running the following command:

cd <project-path> && npm run test -- --files "tests/unit/project.spec.ts" --tests "create project with UUID"

If I add --watch flag to the command I get slightly different output but it still doesn't watch for the updates:

[ info ] booting application to run tests...

unit / Project Model (tests/unit/project.spec.ts)
  ✔ create project with UUID (209.2ms)

 PASSED 

Tests  1 passed (1)
 Time  242ms
[ info ] watching file system for changes...

Any help will be highly appreciated because right now I'm stuck :(

Thanks in advance! ❤️

On further research I found that changing tests.forceExit to true in adonisrc.ts makes tests reload, suggesting that somehow my app gets stuck and doesn't teardown properly.

However as it currently stands I have no idea how to debug it. I have only 2 non-default providers enabled: lucid and my own.

I can disable my own, but it doesn't affect anything. Could it be because I somehow need to teardown lucid service?

I have figured this out on my own: the cause was that I was opening postgres connection in a module outside of the service container, which didn't provide any way to close said connection. This caused adonis to "hang" waiting for the connection.

Because of this neither test reloading, nor commands such as node ace migrate:run worked correctly - they were waiting for connection to close.

I have solved this issue by restructuring my project code and putting connection logic into service & bootstrapping it using service provider.
This way I was able to terminate the connection explicitly in the shutdown() container hook.
