I'm using WSL on Windows 10. I'm able to build from source and run the unit tests. Integration tests are failing for me when I run test/functional/test_runner.py --extended with error AssertionError: [node 0] Error: no RPC connection
I'm guessing bitcoind has to be running. If that's the case, do I have to sync it just to run the tests?
Full error:
Temporary test directory at /tmp/test_runner_₿_????_20220504_123152

`\ The test framework starts its own bitcoind instances, you don't need to have bitcoind separately.
This error is an indication that a bitcoind is failing to start when test framework tries to start it. If you look at the full output, you'll see that it is actually a combination of multiple errors. The line that actually matters is
test_framework.test_node.FailedToStartError: [node 0] bitcoind exited with status 3 during initialization
It is not clear why it isn't starting, but a good place to start looking is in the test datadir located at /tmp/test_runner_₿_????_20220504_123152/cache.
