Title: Bitcoin Core Functional Tests Fail When Running on WSL2 on Windows 10
Introduction:
Bitcoin tests have become increasingly important as they allow developers to thoroughly test and validate new versions of the cryptocurrency before deploying them to the mainnet. However, running functional tests for Bitcoin Core can be difficult for a variety of reasons, including resource constraints (e.g. disk space), compatibility issues with different operating systems (Windows 10), and specific test setup requirements.
Problem:
The article reports that a user is experiencing a crash when running Bitcoin core functional tests using the Windows Subsystem for Linux (WSL2) environment on Windows 10. Specifically, they mention that the following tests are failing:
feature_fee_estimation.py
...(other test files)
Symptoms:
The symptoms reported by the user indicate that the Bitcoin core functional tests are failing, with some of them even triggering an error message.
Possible Causes:
There could be several reasons why the tests are failing:
- Insufficient Disk Space: The 4GB hard drive mounted in /mnt/tmp may not have enough disk space for testing purposes.
- WSL2 Compatibility Issues:
The user may be using a different version of WSL2 or have specific issues with the environment that prevent the tests from running successfully.
- Test File Dependencies: Some test files may require specific versions or configurations that have not yet been implemented in Bitcoin Core.
Potential Workarounds:
To resolve these issues, consider the following potential workarounds:
- Increase Disk Space: Make sure there is enough space on the mounted 4GB temporary hard drive by mounting more drives or using an external storage device.
- Update WSL2 and Bitcoin Core: Check for WSL2 and Bitcoin Core version updates to ensure you are using the latest and most compatible versions.
- Verify Test File Dependencies: Review the test files to identify any dependencies that may not yet be implemented in Bitcoin Core, and consider updating or modifying them as needed.
Conclusion:
Running functional tests of Bitcoin Core can be difficult in WSL2 on Windows 10 for a variety of reasons. By increasing disk space, updating software, and verifying test file dependencies, users can resolve these issues and run tests successfully.
