Title: Bitcoin Core Functional Tests Not Working on WSL2 on Windows 10
Introduction:
Bitcoin testing has become increasingly important as it allows developers to thoroughly test and validate new versions of the cryptocurrency before deploying them to the mainnet. However, performing functional tests on Bitcoin Core can be challenging for a variety of reasons, such as limited resources (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 failures when running Bitcoin core functional tests using WSL2 (Windows Subsystem for Linux) on Windows 10. Specifically, the following tests are reported to be failing:
feature_fee_estimation.py
- “…” (other test files)
Symptoms:
The symptoms reported by the user indicate that Bitcoin core functional tests are failing, with some even generating an error message.
Possible Causes:
There could be several reasons why the tests are failing:
- Insufficient Disk Space: The 4GB temp HD mounted in /mnt/tmp may not have enough free disk space for testing purposes.
- WSL2 Compatibility Issues: The user may be using a different version of WSL2 or may be experiencing specific environmental issues that are preventing it from running successfully.
- Test File Dependencies: Some test files may require specific versions or configurations that are not yet implemented in Bitcoin core.
Potential Solutions:
There are a few potential solutions to consider to resolve these issues.
- Increase Disk Space: Ensure that the 4GB temp HD mounted has enough space by adding more disks or using an external storage device.
- Update WSL2 and Bitcoin Core: Check for updates to WSL2 and Bitcoin core versions to ensure you are using the latest and most compatible versions.
- Check Test File Dependencies:
Review the test files to identify dependencies that may not yet be implemented in Bitcoin core, and consider updating or modifying them as needed.
Conclusion:
Performing functional tests for the Bitcoin core can be challenging on WSL2 on Windows 10 for a variety of reasons. By increasing disk space, updating software, and checking test file dependencies, users can help resolve these issues and successfully run tests.
