Cursor Tests Fail Because Focus Manager Is Not Reset Correctly
Introduction
Cursor tests in cursor_test.js within the Movement suite are failing due to an issue with the focus manager not being reset correctly. This problem is causing the tests to fail with error messages indicating that no highlight SVG is found corresponding to the connection. In this article, we will delve into the root cause of the issue, provide a solution, and discuss the implications of this problem.
The Root Cause
The root cause of the issue is that the focus manager state is not correctly cleared during teardown between tests. The focus manager still holds a location and attempts to set passive focus on it, but fails because there is no corresponding SVG element to update. This is a critical issue that needs to be addressed to ensure the tests run smoothly and accurately.
The Impact
The impact of this issue is significant, as it affects the accuracy and reliability of the cursor tests. When the focus manager is not reset correctly, it can lead to incorrect test results, which can have far-reaching consequences. It is essential to identify and resolve this issue to ensure that the tests are running correctly and providing valuable insights into the functionality of the cursor.
The Solution
The solution to this issue is to add a reset function in the focus manager and use it during teardown. This can be achieved by adding the following code:
export function resetFocusManager() {
focusManager = null;
}
This reset function will clear the focus manager state, ensuring that it is reset to its initial state before each test. By using this function during teardown, we can prevent the focus manager from holding a location and attempting to set passive focus on it, which is causing the tests to fail.
The Implications
The implications of this issue are significant, as it highlights a critical problem with the focus manager cleanup. The fact that the focus manager is not being reset correctly suggests that there is an issue with the teardown process. This is a critical area that needs to be investigated and resolved to ensure that the tests are running accurately and providing valuable insights into the functionality of the cursor.
Investigation
The investigation into this issue will involve a thorough analysis of the focus manager cleanup process. This will involve reviewing the code, identifying the root cause of the issue, and implementing a solution to resolve the problem. The investigation will also involve testing the solution to ensure that it is effective and does not introduce any new issues.
Conclusion
In conclusion, the cursor tests in cursor_test.js within the Movement suite are failing due to an issue with the focus manager not being reset correctly. The root cause of the issue is that the focus manager state is not correctly cleared during teardown between tests. The solution to this issue is to add a reset function in the focus manager and use it during teardown. This will ensure that the focus manager is reset to its initial state before each test, preventing the tests from failing due to the focus manager holding a location and attempting to set passive focus on it.
Recommendations
Based on the investigation and analysis of the issue, the following recommendations are made:
- Add a reset function in the focus manager to clear focus manager state during teardown.
- Use the reset function during teardown to ensure that the focus manager is reset to its initial state before each test.
- Investigate the focus manager cleanup process to identify the root cause of the issue and implement a solution to resolve the problem.
Future Work
The future work on this issue will involve continuing to investigate the focus manager cleanup process to identify the root cause of the issue and implement a solution to resolve the problem. This will involve reviewing the code, testing the solution, and ensuring that it is effective and does not introduce any new issues.
