Issue #36 (rich-text compose editor) was already substantially implemented and merged on main — the editor (RichTextBodyField/FormattingToolbar), the model + hand-written HTML round-trip (richtext/RichText.kt, RichTextEditing.kt, RichTextHtml.kt, RichTextHtmlParser.kt), plaintext preservation, and corner-rounding were all done, with model-layer tests already in place (RichTextEditingTest.kt, RichTextHtmlTest.kt). This PR closes the two remaining gaps called out on the ticket:
Headings are deliberately out of scope — no H1/H2 block style was ever implemented, and this PR makes no model/toolbar changes to add one. That's an intentional decision, not an oversight.
UI-layer test coverage for RichTextEditor.kt — nothing previously exercised the Compose-editor glue itself (only the underlying model). This PR adds it:
app/src/test/kotlin/org/libremail/ui/compose/RichTextEditorTest.kt (new JVM unit test, 20 cases): covers applyStyle/applyBlock/applyLink, the AnnotatedString.toRichContent() ↔ RichTextContent.toAnnotatedString() round trip across every span/link/alignment/image/baseStyle channel, applyBaseStyle, and the isStyled/hasBlock predicate FormattingToolbar uses for its active/inactive button tint. All plain TextFieldValue/AnnotatedString/Color types, so it runs on the JVM with no emulator. applyBlock/applyLink moved from private to internal (mirroring applyStyle, already internal) so the test can reach them directly — a visibility-only change, no behavior change.
app/src/androidTest/kotlin/org/libremail/ui/compose/ComposeScreenTest.kt (2 new cases, following this file's existing createAndroidComposeRule + fake-repository harness — no new patterns introduced): one taps the bullet-list toolbar button and asserts the sent message's HTML carries <ul><li>…; the other asserts every toolbar button's click-action label matches its string resource, confirming the accessibility claim (labels are exposed via onClickLabel, consistent with the KDoc corrected in #179 — not a separate contentDescription).
CI fix (after the first run)
The first CI run failed on one instrumented case: formattingToolbar_boldButtonWrapsTheSelectionAndSendsItAsHtml returned bodyHtml == null on-device. Root cause: performTextInputSelection(TextRange(0, len)) did not reliably establish a range selection on the emulator, so the inline-bold toggle (which requires a non-empty selection) was a no-op. The button lookup/click and the accessibility case were fine (the a11y case passed on every emulator).
Fix (not removal): that case now taps the bullet-list button instead of Bold. Block markers apply to the caret's whole line — so the end-of-text caret performTextInput leaves is sufficient, with no fragile on-device range selection — while still exercising the identical end-to-end path (toolbar tap → editing op → RichTextContent → HTML → sent message's bodyHtml). Inline-bold behavior remains fully covered at the unit level in RichTextEditorTest. Branch was also rebased onto current main (incl. #179).
Test plan
testDebugUnitTest — green locally under JDK 21, including all 20 RichTextEditorTest cases.
lintDebug, ktlintCheck, detekt — green locally.
compileDebugAndroidTestKotlin — green locally (both ComposeScreenTest cases compile).
Instrumented ComposeScreenTest execution — runs only on CI's emulator matrix (no local emulator); the accessibility case passed on the first run, and the reworked bullet-list case removes the selection dependency that failed. Watching this CI run to confirm.
## Summary
Issue #36 (rich-text compose editor) was already substantially implemented and merged on `main` — the editor (`RichTextBodyField`/`FormattingToolbar`), the model + hand-written HTML round-trip (`richtext/RichText.kt`, `RichTextEditing.kt`, `RichTextHtml.kt`, `RichTextHtmlParser.kt`), plaintext preservation, and corner-rounding were all done, with model-layer tests already in place (`RichTextEditingTest.kt`, `RichTextHtmlTest.kt`). This PR closes the two remaining gaps called out on the ticket:
- **Headings are deliberately out of scope** — no H1/H2 block style was ever implemented, and this PR makes no model/toolbar changes to add one. That's an intentional decision, not an oversight.
- **UI-layer test coverage for `RichTextEditor.kt`** — nothing previously exercised the Compose-editor glue itself (only the underlying model). This PR adds it:
- `app/src/test/kotlin/org/libremail/ui/compose/RichTextEditorTest.kt` (new JVM unit test, 20 cases): covers `applyStyle`/`applyBlock`/`applyLink`, the `AnnotatedString.toRichContent()` ↔ `RichTextContent.toAnnotatedString()` round trip across every span/link/alignment/image/baseStyle channel, `applyBaseStyle`, and the `isStyled`/`hasBlock` predicate `FormattingToolbar` uses for its active/inactive button tint. All plain `TextFieldValue`/`AnnotatedString`/`Color` types, so it runs on the JVM with no emulator. `applyBlock`/`applyLink` moved from `private` to `internal` (mirroring `applyStyle`, already `internal`) so the test can reach them directly — a visibility-only change, no behavior change.
