Title: Bitcoin Core Functional Tests Failing Running 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 mainnet. However, running functional tests for Bitcoin core can be challenging due to various reasons such as limited resources (e.g., disk space), compatibility issues with different operating systems (Windows 10), and specific test setup requirements.
The Issue:
The article reports that a user is experiencing failures when running Bitcoin core functional tests using the WSL2 (Windows Subsystem for Linux) environment on Windows 10. Specifically, they mention that the following tests are failing:
feature_fee_estimation.py
...(the remaining test files)
Symptoms:
The symptoms reported by the user indicate that the Bitcoin core functional tests are not passing, and some of them are even causing an error message.
Possible Causes:
There could be several reasons why the tests are failing:
- Insufficient disk space: The 4GB temp HD mounted on /mnt/tmp might not have enough available disk space for testing purposes.
- Compatibility issues with WSL2: The user might be using a different version of WSL2 or experiencing specific issues with the environment that prevent the tests from running successfully.
- Test file dependencies: Some test files might require specific versions or configurations that are not yet implemented in Bitcoin core.
Potential Solutions:
To resolve these issues, here are some potential solutions to consider:
- Increase disk space: Ensure that there is sufficient available disk space on the 4GB temp HD mounted by mounting more disks or using an external storage device.
- Update WSL2 and Bitcoin core:
Check for updates to the WSL2 and Bitcoin core versions to ensure you are running the latest and most compatible versions.
- Verify test file dependencies: Review the test files to identify any dependencies that might not be yet implemented in Bitcoin core, and consider updating or modifying them as needed.
Conclusion:
Running functional tests for Bitcoin core can be challenging on WSL2 on Windows 10 due to various reasons. By increasing disk space, updating software, and verifying test file dependencies, users can help resolve these issues and successfully run their tests.
