Cursor Test Fails: In - From Output Connection

Introduction

In this article, we will be discussing a cursor test that fails due to a specific issue with the focus manager changes in a line cursor. The test in question is the "In - From output connection" test, which is used to verify the functionality of the cursor in a specific scenario. We will delve into the details of the issue, its proximate cause, and the necessary updates to resolve the problem.

Description of the Issue

The test fails after the focus manager changes to the line cursor. The test is designed to verify that the cursor can be placed on an output connection and then moved in to reach the field block node. However, the proximate cause of the failure is that output connections are not given highlight paths in drawer.updateConnectionHighlights because they live at the block level instead of in the rows.

Understanding the Proximate Cause

The issue lies in the way output connections are handled in the drawer.updateConnectionHighlights function. Currently, this function only provides highlight paths for input connections, not output connections. This is because output connections are located at the block level, rather than in the rows. As a result, when the cursor is placed on an output connection, the updateConnectionHighlights function is not able to provide the necessary highlight paths, leading to the test failure.

Keyboard Experimentation Plugin

The keyboard experimentation plugin is another area where the issue arises. In this plugin, the cursor is sometimes (or always) placed on the block's node or the parent input connection's node, rather than on an output connection. This is because the plugin is designed to work with input connections, not output connections.

Possible Solutions

There are two possible solutions to this issue:

1. Update updateConnectionHighlights: The first solution is to update the updateConnectionHighlights function to provide highlight paths for output connections. This would require modifying the function to take into account the location of output connections at the block level.
2. Throw an error when placing cursor on output connection: The second solution is to throw an error when the cursor is placed on an output connection. This would ensure that the test fails immediately, rather than later on when the cursor is moved in.

Local Test Updates

To make the test useful again, the initial cursor location can be set to block A's first input connection. This would allow the test to verify that the cursor can be placed on an input connection and then moved in to reach the field block node.

Introduction

In our previous article, we discussed the issue with the cursor test failing due to a specific problem with the focus manager changes in a line cursor. In this article, we will provide a Q&A section to address some of the common questions related to this issue.

Q: What is the proximate cause of the cursor test failure?

A: The proximate cause of the cursor test failure is that output connections are not given highlight paths in drawer.updateConnectionHighlights because they live at the block level instead of in the rows.

Q: Why are output connections not given highlight paths?

A: Output connections are not given highlight paths because they live at the block level, rather than in the rows. This makes it difficult for the updateConnectionHighlights function to provide the necessary highlight paths.

Q: What is the keyboard experimentation plugin, and how does it relate to the issue?

A: The keyboard experimentation plugin is a feature that allows users to experiment with keyboard shortcuts. In this plugin, the cursor is sometimes (or always) placed on the block's node or the parent input connection's node, rather than on an output connection. This is because the plugin is designed to work with input connections, not output connections.

Q: What are the possible solutions to this issue?

A: There are two possible solutions to this issue:

1. Update updateConnectionHighlights: The first solution is to update the updateConnectionHighlights function to provide highlight paths for output connections.
2. Throw an error when placing cursor on output connection: The second solution is to throw an error when the cursor is placed on an output connection.

Q: How can I make the test useful again?

A: To make the test useful again, you can set the initial cursor location to block A's first input connection. This will allow the test to verify that the cursor can be placed on an input connection and then moved in to reach the field block node.

Q: What are the reproduction steps to reproduce the issue?

A: To reproduce the issue, follow these steps:

Q: What is the stack trace for this issue?

A: The stack trace for this issue is:

# No stack trace provided

Q: Are there any screenshots or browser information available for this issue?

A: No, there are no screenshots or browser information available for this issue.

Q: How can I resolve this issue?

A: To resolve this issue, you can either update the updateConnectionHighlights function to provide highlight paths for output connections or throw an error when the cursor is placed on an output connection.

Conclusion

In conclusion, the cursor test fails due to a specific issue with the focus manager changes in a line cursor. The proximate cause of the failure is that output connections are not given highlight paths in drawer.updateConnectionHighlights because they live at the block level instead of in the rows. By understanding the issue the possible solutions, you can resolve this issue and make the test useful again.
