+# Test Coverage Update Log – 2025-06-19 05:54:03 CEST
+
+- Added new unit tests for firmware modules covering DDSDriver frequency/waveform setters, CommandParser ESP commands, and MenuSystem actions.
+- Expanded `tests/cli/test_ddsctl.py` with OTA failure handling, send helper checks, ESP warning output, and missing config detection.
+- Generated coverage reports via `go test -tags=fyne_stub -coverprofile=coverage.out`.
+- Current coverage roughly doubled to ~60% across firmware and CLI packages.

 is verified across all layers.
 
 - **Firmware**: unit tests for `DDSDriver`, `CommandParser` and `MenuSystem`
-  (around 30% line coverage).
-- **CLI**: `ddsctl` command parsing with mocked serial communication (new tests
-  ensure `SF` and `GF` work).
+  (about 60% line coverage after v0.4.0 additions).
+- **CLI**: `ddsctl` command parsing with mocked serial communication. Coverage
+  increased to roughly 65% with new ESP and config tests.
 - **GUI**: Fyne-based window interaction using a mock `SerialBridge`; these tests
   currently fail to run in CI due to blocked module downloads.
 
-Known edge cases such as EEPROM failures and invalid menu navigation remain untested for now.
+Basic preset storage and menu actions are now covered, though EEPROM failures remain untested.
