+# Terminal Integration Test Suite
2
+
3
+Comprehensive test suite for fortsh terminal standardization features.
4
+
5
+## Overview
6
+
7
+This test suite validates all 6 phases of terminal standardization implemented in fortsh:
8
+
9
+- **Phase 1**: Window Size Detection & SIGWINCH
10
+- **Phase 2**: Bracketed Paste Mode
11
+- **Phase 3**: Prompt Width Calculation
12
+- **Phase 4**: Job Specs & Terminal Title
13
+- **Phase 5**: Terminal Type Adaptation
14
+- **Phase 6**: Polish & Optional Features (UTF-8, True Color)
15
+
16
+## Test Files
17
+
18
+### `terminal_integration_tests.sh`
19
+**Automated tests** that can run in CI/CD environments.
20
+
21
+```bash
22
+# Run all automated tests
23
+./tests/terminal_integration_tests.sh
24
+
25
+# Set custom fortsh binary
26
+FORTSH=./bin/fortsh ./tests/terminal_integration_tests.sh
27
+```
28
+
29
+**What it tests:**
30
+- ✅ Environment variables (`$COLUMNS`, `$LINES`)
31
+- ✅ Terminal type detection (`TERM=dumb`, `TERM=xterm`, etc.)
32
+- ✅ UTF-8 character handling
33
+- ✅ True color pass-through
34
+- ✅ Integration across phases
35
+
36
+**Limitations:**
37
+- Cannot test interactive features (paste, job control, resize)
38
+- Cannot verify visual output (colors, cursor positioning)
39
+- Runs in non-interactive mode (`-c` flag)
40
+
41
+### `terminal_interactive_tests.sh`
42
+**Manual tests** requiring user interaction.
43
+
44
+```bash
45
+# Run interactive test menu
46
+./tests/terminal_interactive_tests.sh
47
+
48
+# Run all tests sequentially
49
+./tests/terminal_interactive_tests.sh --all
50
+```
51
+
52
+**What it tests:**
53
+- ✅ Bracketed paste mode (multi-line paste behavior)
54
+- ✅ Window resize (SIGWINCH) handling
55
+- ✅ Colored prompts & cursor positioning
56
+- ✅ Job control & job specs (`%%`, `%-`, `%1`, `%?string`)
57
+- ✅ Terminal title updates
58
+- ✅ UTF-8 wide character cursor positioning
59
+
60
+**Menu Options:**
61
+1. Bracketed Paste Mode
62
+2. Window Resize (SIGWINCH)
63
+3. Colored Prompts & Cursor Positioning
64
+4. Job Control & Job Specs
65
+5. Terminal Title Updates
66
+6. UTF-8 Wide Characters
67
+7. Run ALL tests
68
+0. Exit

145
+## Test Results Interpretation
146
+
147
+### Automated Tests
148
+
149
+**PASS**: Feature working correctly
150
+- Green ✓ checkmark
151
+- Increments pass counter
152
+
153
+**FAIL**: Feature not working
154
+- Red ✗ mark with error message
155
+- Increments fail counter
156
+- Test suite exits with code 1
157
+
158
+**SKIP**: Test cannot run in current environment
159
+- Yellow ⊘ mark with reason
160
+- Increments skip counter
161
+- Examples: interactive features, terminal-specific tests
162
+
163
+### Interactive Tests
164
+
165
+User manually verifies behavior and responds with `y/N`:
166
+- `y` = Test passed (feature works)
167
+- `N` = Test failed (feature broken)
168
+
169
+## CI/CD Integration
170
+
171
+### GitHub Actions Example
172
+
173
+```yaml
174
+name: Terminal Tests
175
+
176
+on: [push, pull_request]
177
+
178
+jobs:
179
+  terminal-tests:
180
+    runs-on: ubuntu-latest
181
+    steps:
182
+      - uses: actions/checkout@v3
183
+      - name: Build fortsh
184
+        run: make
185
+      - name: Run terminal integration tests
186
+        run: ./tests/terminal_integration_tests.sh
187
+```
188
+
189
+### Expected Results in CI
190
+
191
+In CI environments (non-interactive), many tests will **SKIP**:
192
+- Bracketed paste (requires terminal)
193
+- SIGWINCH (requires resize event)
194
+- Job control (requires interactive mode)
195
+- Terminal title (requires real terminal)
196
+
197
+This is **normal and expected**. The automated tests focus on:
198
+- Environment variable correctness
199
+- Terminal type detection logic
200
+- UTF-8 handling
201
+- Output correctness
202
+
203
+## Troubleshooting
204
+
205
+### "fortsh binary not found"
206
+
207
+```bash
208
+# Build fortsh first
209
+make clean && make
210
+
211
+# Or specify path
212
+FORTSH=/path/to/fortsh ./tests/terminal_integration_tests.sh
213
+```
214
+
215
+### "Test skipped: Requires interactive mode"
216
+
217
+This is normal for automated tests. Run interactive tests instead:
218
+
219
+```bash
220
+./tests/terminal_interactive_tests.sh
221
+```
222
+
223
+### Interactive tests don't work
224
+
225
+Ensure you're in a real terminal (not CI):
226
+```bash
227
+# Check if terminal
228
+if [[ -t 0 ]]; then echo "Terminal"; else echo "Not a terminal"; fi
229
+```
230
+
231
+### Colors not showing in output
232
+
233
+Check `$TERM`:
234
+```bash
235
+echo $TERM  # Should be xterm-256color or similar
236
+```
237
+
238
+If `TERM=dumb`, colors are intentionally disabled (this is correct behavior).
239
+
240
+## Adding New Tests
241
+
242
+### Automated Test Template
243
+
244
+```bash
245
+test_start "My new feature"
246
+output=$(run_fortsh 'echo "test"')
247
+if assert_equals "test" "$output"; then
248
+    test_pass
249
+else
250
+    test_fail "Feature broken"
251
+fi
252
+```
253
+
254
+### Interactive Test Template
255
+
256
+```bash
257
+test_my_feature() {
258
+    test_section "Test: My Feature"
259
+
260
+    cat <<EOF
261
+${BOLD}This test verifies my feature.${RESET}
262
+
263
+Instructions:
264
+1. Do something
265
+2. Verify behavior
266
+3. Type 'exit'
267
+EOF
268
+
269
+    prompt_user "Ready to test?"
270
+    FORTSH_RC_FILE=/dev/null "$FORTSH"
271
+
272
+    read -p "Did it work? [y/N] " response
273
+    if [[ "$response" =~ ^[Yy]$ ]]; then
274
+        echo -e "${GREEN}✓ Test PASSED${RESET}"
275
+    else
276
+        echo -e "${RED}✗ Test FAILED${RESET}"
277
+    fi
278
+}
279
+```
280
+
281
+## Test Development Guidelines
282
+
283
+1. **Keep automated tests fast** - No sleep, no timeouts
284
+2. **Make interactive tests clear** - Explicit instructions
285
+3. **Test one thing at a time** - Focused, isolated tests
286
+4. **Document expected behavior** - What should happen
287
+5. **Handle both pass and fail** - Don't assume success
