 **Important**: Always quote glob patterns to prevent shell expansion. Without quotes, the shell will expand the pattern and only pass the first matching file to tstest.
 
-### Automatic Logging
+### Enhanced Test Logging
+
+The `--logfile` option provides intelligent test logging with automatic organization:
 
-Use `--logfile` to automatically save test output:
 ```bash
 tstest test/ --logfile
 ```
 
-This creates detailed logs in `.nogit/testlogs/[testname].log` for each test file.
+**Log Organization:**
+- **Current Run**: `.nogit/testlogs/[testname].log`
+- **Previous Run**: `.nogit/testlogs/previous/[testname].log`
+- **Failed Tests**: `.nogit/testlogs/00err/[testname].log`
+- **Changed Output**: `.nogit/testlogs/00diff/[testname].log`
+
+**Features:**
+- Previous logs are automatically moved to the `previous/` folder
+- Failed tests create copies in `00err/` for quick identification
+- Tests with changed output create diff reports in `00diff/`
+- The `00err/` and `00diff/` folders are cleared on each run
+
+**Example Diff Report:**
+```
+DIFF REPORT: test__api__integration.log
+Generated: 2025-05-24T01:29:13.847Z

+

+### Test Timeout Protection
+
+Prevent runaway tests with the `--timeout` option:
+
+```bash
+# Timeout any test file that runs longer than 60 seconds
+tstest test/ --timeout 60
+
+# Shorter timeout for unit tests
+tstest test/unit/ --timeout 10
+```
+
+When a test exceeds the timeout:
+- The test process is terminated (SIGTERM)
+- The test is marked as failed
+- An error log is created in `.nogit/testlogs/00err/`
+- Clear error message shows the timeout duration
+
+### Test File Range Control
+
+Run specific ranges of test files using `--startFrom` and `--stopAt`:
+
+```bash
+# Run tests starting from the 5th file
+tstest test/ --startFrom 5
+
+# Run only files 5 through 10
+tstest test/ --startFrom 5 --stopAt 10
+
+# Run only the first 3 test files
+tstest test/ --stopAt 3
+```
+
+This is particularly useful for:
+- Debugging specific test failures in large test suites
+- Running tests in chunks on different CI runners
+- Quickly testing changes to specific test files
+
+The output shows which files are skipped:
+```
+⏭️  test/auth.test.ts (1/10)
+   Skipped: before start range (5)
+⏭️  test/user.test.ts (2/10)
+   Skipped: before start range (5)
+▶️  test/api.test.ts (5/10)
+   Runtime: node.js
+   ✅ api endpoints work (145ms)
+```
