Inconsistent indentation using spaces instead of tabs for the runtime import.
Impact: gofmt will fail and code won't pass formatting checks.

Pull request overview
This PR aims to make the Go test suite more Windows-compatible by avoiding OS-specific error-string mismatches and skipping tests that rely on Unix-only filesystem semantics (permissions, symlinks, filename wildcards, and some watcher/timing behavior).
Changes:
- Added a
testutils.NormalizeErrorMessagehelper to normalize Windows error strings for cross-platform assertions. - Relaxed/normalized several error-message assertions to be less OS-dependent.
- Added Windows-specific skips for tests that currently behave differently or are unreliable on Windows (timing, file watchers, symlinks, chmod semantics).

Skipping these tests on Windows due to error message differences conflicts with the PR goal of OS-agnostic error assertions. Since this file already imports internal/testutils, consider normalizing error strings (or using errors.Is with os.ErrNotExist) so the tests can still run on Windows.

These tests are written to exercise Jaeger's internal error paths, not stdlib. The simple solution is to ensure that the error paths are wrapping the original error with a custom message and to assert only on that custom message, not on the error from stdlib (which is not stable).

"The process cannot access the file because it is being used by another process." indicates a sharing/locking error, not a missing-file error. Normalizing it to "no such file or directory" can hide real failures (tests may pass even when the issue is file locking). Consider leaving this message unchanged or mapping it to a closer Unix equivalent (e.g., "resource busy"), and keep ENOENT normalization limited to the "cannot find" cases.

- These files are created via string concatenation (tempDir + "test-file-1"), which places them outside the TempDir directory (and therefore outside Go’s automatic cleanup). Use filepath.Join(tempDir, ...) (or create inside a subdir) so the files are actually under tempDir and reliably cleaned up across platforms.
tempDir := t.TempDir()
testFile1, err := os.Create(tempDir + "test-file-1")
require.NoError(t, err)
defer testFile1.Close()
testFile2, err := os.Create(tempDir + "test-file-2")
require.NoError(t, err)
internal/storage/v1/elasticsearch/mappings/command_test.go:30
- This test is skipped on Windows due to using os.Create with a literal '' in the filename. Instead of skipping, create the temp file with os.CreateTemp(t.TempDir(), "command-output-.txt") (which expands '*' safely) and ensure the file is closed (e.g., defer tempFile.Close()) so the test can run on Windows too.
func TestCommandExecute(t *testing.T) {
if runtime.GOOS == "windows" {
t.Skip("Wildcard * in filenames not supported on Windows")
}
cmd := Command()

require.NoError(t, err)
cmd/jaeger/internal/extension/jaegerquery/internal/static_handler_test.go:42
- Rather than skipping on Windows, this assertion can likely be made portable by normalizing the OS-specific error string (e.g., using testutils.NormalizeErrorMessage(err.Error())) before comparing/containing. Skipping here drops coverage for logic that should be OS-agnostic.
func TestNotExistingUiConfig(t *testing.T) {
if runtime.GOOS == "windows" {
t.Skip("Windows path error messages differ")
}
handler, err := NewStaticAssetsHandler("/foo/bar", StaticAssetsHandlerOptions{
Logger: zap.NewNop(),
})
require.ErrorContains(t, err, "no such file or directory")
assert.Nil(t, handler)
cmd/jaeger/internal/extension/jaegerquery/internal/static_handler_test.go:66
- Instead of skipping on Windows, consider normalizing the logged error message before asserting (e.g., normalize buf.String() or normalize the error string that is logged). This keeps coverage while still allowing OS-specific error text differences.
func TestRegisterStaticHandlerPanic(t *testing.T) {
if runtime.GOOS == "windows" {
t.Skip("Windows path error messages differ")
}
logger, buf := testutils.NewLogger()
assert.Panics(t, func() {
closer := RegisterStaticHandler(
http.NewServeMux(),
logger,
&QueryOptions{
UIConfig: UIConfig{
AssetsPath: "/foo/bar",
},
},
querysvc.StorageCapabilities{ArchiveStorage: false},
)
defer closer.Close()
})
assert.Contains(t, buf.String(), "Could not create static assets handler")
assert.Contains(t, buf.String(), "no such file or directory")
}
cmd/jaeger/internal/extension/jaegerquery/internal/static_handler_test.go:261
- This test is skipped on Windows due to exact error string matching. It should be possible to keep the test running cross-platform by comparing against a normalized error message (testutils.NormalizeErrorMessage(err.Error())) or by using ErrorContains on a stable substring instead of require.EqualError with OS-specific text.
func TestLoadUIConfig(t *testing.T) {
if runtime.GOOS == "windows" {
t.Skip("Windows path error messages differ")
}
type testCase struct {
configFile string
expected *loadedConfig
expectedError string

config, err := loadUIConfig(testCase.configFile)
if testCase.expectedError != "" {
