Hi thanks for the PR, but I'm not sure I'm seeing the issue. Can you describe what problem you're having?

Hi.
User problem: I can not navigate to the next failing test case inside of the summary if test cases of multiple files are displayed and the next failing test case is in the last displayed file.

Code issue:
The issue is that the while loop uses len(s:test_line_map) and uses index like an index of a list.
But test_line_map is a dictionary.
If you have test cases in the summary from multiple files (separated by empty lines) the keys of test_line_map represent the actual line number in the summary where the test is printed.
let s:test_line_map[len(a:group_state.lines)] = [a:test.file, a:test.id]
But because of the empty lines the last keys of the dict are not accessible if one uses len(s:test_line_map) as the max index.

My idea was to go through the summary buffer line by line and check each line for a failing test case.

Ah that makes sense thanks for the PR!
