while find scenario asserts

Error message

while find scenario asserts: %w

What it means

GetScenariosCoverage globs <hubDir>/.tests/*/scenario.assert files; a malformed glob pattern aborts with 'while find scenario asserts: <err>'. Same ErrBadPattern failure mode as the parser coverage path, applied to scenario asserts.

Solutions

1. Remove or escape glob metacharacters in the hubDir path (filepath.Escape)
2. Rename the directory to one without '[', ']', '?', '*'
3. Pass a plain absolute literal path as hubDir

Example fix

// before
GetScenariosCoverage("/tmp/hub[test]", ...)
// after
GetScenariosCoverage(filepath.Escape("/tmp/hub[test]"), ...)

if strings.ContainsAny(hubDir, "[]*?") {
    hubDir = filepath.Escape(hubDir)
}
if _, err := filepath.Glob(filepath.Join(hubDir, ".tests", "*", "scenario.assert")); err != nil {
    return err
}

cov, err := hubtest.GetScenariosCoverage(hubDir, ...)
if err != nil {
    if strings.Contains(err.Error(), "syntax error in pattern") { /* sanitize hubDir and retry */ }
}

When it happens

Trigger: Calling GetScenariosCoverage(hubDir, ...) when hubDir (or the joined pattern) contains unbalanced glob metacharacters such as '[' causing filepath.Glob to return ErrBadPattern.

Common situations: Hub directory path containing bracketed or wildcard characters (sandbox/test dir names like 'dir[0]'); hubDir accidentally containing a glob expression instead of a literal path.

Understand the failure class

Background: "Invalid URL" errors: why new URL(), URI.parse, and reqwest::Url reject your string — missing scheme, whitespace, and bad path format — this error's family across 39 libraries.
