+# Target Child ID Tests Documentation
+
+## Overview
+
+The **TargetChildID** test suite contains automated end-to-end tests for the Target Child Information and Birth Outcomes (TCID) form. This multi-tab form collects comprehensive information about the target child (newborn) including birth outcomes, health insurance, medical provider information, PHQ-9 depression screening, and MIECHV-specific data.
+
+## What is Target Child ID (TCID)?
+

+
+**Purpose**:
+- Document birth outcomes and vital statistics
+- Track health insurance and medical provider information
+- Conduct PHQ-9 depression screening for caregivers
+- Collect MIECHV-required data elements
+- Record additional optional items (parity, delivery type, breastfeeding)
+
+**Workflow**:
+```
+Navigate to Forms Tab
+    ↓
+Click "Target Child Information and Birth Outcomes" link

+
+## Important Concepts
+
+### 1. Multi-Tab Form Structure
+
+**5 Tabs**:
+- Target Child (birth info)
+- Health Insurance (Medicaid, insurance, medical provider)
+- Additional Items (parity, delivery, breastfeeding)
+- PHQ-9 (depression screening)
+- MIECHV (MIECHV-specific data)
+
+**Navigation Pattern**: Use `SwitchToTab()` helper between tabs
+
+**Submission**: Submit button is in panel footer, visible on all tabs
+
+**Validation**: Validation summary appears on all tabs, shows errors from all tabs
+
+---
+
+### 2. Progressive Validation
+
+**Pattern**: Submit form multiple times, filling one required field at a time.
+
+**Flow**:
+```
+Submit empty → 4 validations
+Fill Birth Term → 3 validations
+Fill First Name → 2 validations
+Fill Last Name → 1 validation
+Fill Parity → 0 validations for these fields, new validation for Gestational Age
+Fill Gestational Age → 0 validations
+```
+
+**Purpose**: Demonstrates real-time validation feedback and field dependencies
+
+---
+
+### 3. Medicaid Conditional Logic
+
+**Rule**: If Medicaid = "Yes", all health insurance checkboxes are **disabled**.
+
+**Logic**:
+```
+IF Medicaid = "Yes" (value "1")
+THEN
+    Health insurance checkboxes → Disabled
+    Medicaid case number input → Visible
+ELSE IF Medicaid = "No" (value "0") OR "Unknown" (value "9")
+THEN
+    Health insurance checkboxes → Enabled
+    Medicaid case number input → Hidden (for "No")
+```
+
+**Test Coverage**: Test 6 validates this logic thoroughly
+
+---
+
+### 4. Medical Provider Question (Q19) Conditional Logic
+
+**Rule**: Question 20 (medical provider/facility dropdowns) is controlled by Question 19.
+
+**Logic**:
+```
+IF Q19 = "No" (value "0")
+THEN
+    Medical provider dropdown → Disabled
+    Medical facility dropdown → Disabled
+    "Not in List" doctor link → Disabled class
+    "Not in List" facility link → Disabled class
+ELSE IF Q19 = "Yes" (value "1")
+THEN
+    Medical provider dropdown → Enabled
+    Medical facility dropdown → Enabled
+    "Not in List" doctor link → Enabled
+    "Not in List" facility link → Enabled
+```
+
+---
+
+### 5. Medical Provider/Facility Modals
+
+**"Not in List" Pattern**: When medical provider/facility is not in dropdown, click "Not in List" link to open modal and add new entry.
+
+**Modal Workflow**:
+```
+Click "Not in List" link
+    ↓
+Modal opens
+    ↓
+Fill required fields (Last Name for provider, Name for facility)
+    ↓
+Submit modal
+    ↓
+Modal closes
+    ↓
+New entry appears in dropdown
+    ↓
+New entry is auto-selected
+```
+
+**Validation**: Both modals validate required fields before allowing submission
+
+**Test Coverage**: Test 6 validates both provider and facility modals
+
+---
+
+### 6. PHQ-9 Scoring System
+
+**9 Questions**: Each scored 0-3 (Not at all, Several days, More than half the days, Nearly every day)
+
+**Total Score**: Sum of 9 questions (0-27)
+
+**Result Calculation**:
+- **Score < 10**: Negative
+- **Score >= 10**: Positive
+
+**Validity**:
+- **All 9 answered**: Valid
+- **Any blank**: Invalid, shows "N/A"
+
+**Real-Time Calculation**: Score, Result, and Validity update immediately as user answers questions
+
+**Labels**:
+- `lblPHQ9Score`: Displays total score (0-27) or "N/A"
+- `lblPHQ9Result`: Displays "Positive" or "Negative" or "N/A"
+- `lblPHQ9ScoreValidity`: Displays "Valid" or "Invalid"
+
+**Test Coverage**: Test 8 validates scoring logic with incomplete and complete scenarios
+
+---
+
+### 7. Birth Weight Validation
+
+**Validation Rules**:
+- **Pounds**: Must be < 17
+- **Ounces**: Must be < 16
+
+**Both Rules Enforced**: Both validations can appear simultaneously
+
+**Test Scenarios**:
+- (-1, -2): Both fail
+- (20, 20): Both fail
+- (17, 16): Both fail (boundary)
+- (0-16, 0-15): Pass
+
+**Test Coverage**: Test 5 validates all scenarios
+
+---
+
+### 8. Date Validations
+
+**Prenatal Care Date**:
+- Must be **before** Target Child DOB
+- Validation: "Date Began Receiving Prenatal Care can not start after the birth of the child"
+
+**PHQ-9 Date**:
+- Must be **on or after** Target Child DOB
+- Must be **on or after** Intake Date
+- Validation: "[PHQ-9] The PHQ date administered must be on or after the TC's date of birth!"
+
+**Date Formats Accepted**: `MM/dd/yy` or `MM/dd/yyyy`
+
+---
+
+### 9. Conditional "Other Specify" Fields
+
+**Pattern**: When "Other" option is selected, a "specify" text input appears.
+
+**3 Instances in Form**:
+
+1. **Health Insurance → Other**:
+   - Checkbox: `input[id$='chkTCHIOther']`
+   - Specify: `input[id$='txtTCHIOtherSpecify']`
+
+2. **PHQ-9 → Participant = Other**:
+   - Dropdown: `select[id$='ddlPHQ9Participant']` (value "04")
+   - Specify: `input[id$='txtPHQ9ParticipantSpecify']`
+
+3. **MIECHV → Medical Care Source = Other**:
+   - Dropdown: `select[id$='ddlTCMedicalCareSource']` (value "06")
+   - Specify: `input[id$='txtTCMedicalCareSourceOtherSpecify']`
+
+**Test Coverage**:
+- Test 6: Health Insurance Other
+- Test 8: PHQ-9 Participant Other
+- Test 9: MIECHV Medical Care Source Other
+
+---
+
+### 10. Tooltip Icons
+
+**Location**: Additional Items tab
+
+**Icon**: `span.glyphicon.glyphicon-question-sign`
+
+**Tooltip Display**: `.tooltip-inner`
+
+**Purpose**: Provide helpful explanations for optional fields
+
+**Test Coverage**: Test 7 validates tooltip functionality
+
+---
+
+## What to Keep in Mind
+
+### When Modifying Tests
+
+1. **Test Order Matters**: Tests 4-9 require existing TCID entries created by manual setup or previous test runs.
+
+2. **Multi-Tab Form**: Always switch to correct tab before interacting with fields.
+
+3. **Submit Button Location**: Submit button is in panel footer, visible from all tabs.
+
+4. **Validation Appears on All Tabs**: Validation summary shows errors from all tabs, regardless of which tab you're on.
+
+5. **Partial Class Pattern**: Changes to helper methods in one file affect all test files.
+
+6. **Selector Constants**: All selectors defined as constants at top of TargetChildIDTests.cs.
+
+---
+
+### When Adding New Tests
+
+1. **Assign Priority**: Add `[TestPriority(N)]` with number > 9.
+
+2. **Use Parameterization**: Add `[Theory]` and `[MemberData(nameof(GetTestPc1Ids))]`.
+
+3. **Start with Navigation**: Use `NavigateToTargetChildPage()` and `OpenExistingTcidEntry()` or `OpenNewTcidForm()`.
+
+4. **Use Tab Helpers**: Use `SwitchToTab()` to navigate between tabs.
+
+5. **Log Actions**: Use `_output.WriteLine()` for all significant actions.
+
+6. **Wait After Tab Switch**: Use `WaitForReady()` and `Thread.Sleep()` after tab switches.
+
+7. **Verify with Toast**: Success should show jQuery toast - use `WebElementHelper.GetToastMessage()`.
+
+---
+
+### Common Pitfalls
+
+1. **Tab Not Active**: Forgot to switch to correct tab before interacting with field.
+   - **Solution**: Always use `SwitchToTab()` before finding elements.
+
+2. **Validation Summary Not Found**: Validation redirected to different tab.
+   - **Solution**: Validation summary exists on all tabs - don't switch tabs to find it.
+
+3. **Medicaid Checkbox Enabled When Should Be Disabled**: Medicaid dropdown not set to "Yes".
+   - **Solution**: Ensure Medicaid dropdown selection completes before checking checkboxes.
+
+4. **Modal Not Closing**: Modal close animation takes time.
+   - **Solution**: Use `WaitForElementToDisappear()` with sufficient timeout.
+
+5. **PHQ Score Not Updating**: JavaScript calculation not triggered.
+   - **Solution**: Wait with `WaitForReady()` and `Thread.Sleep()` after setting scores.
+
+6. **Provider/Facility Not Auto-Selected**: Dropdown not refreshed after modal close.
+   - **Solution**: Switch back to Health Insurance tab after modal closes.
+
+7. **Prenatal Date Validation Not Appearing**: Date is actually valid (before birth).
+   - **Solution**: Verify Target Child DOB before setting test date.
+
+8. **Birth Weight Validation Not Clearing**: Values still out of range.
+   - **Solution**: Ensure values are strictly less than limits (< 17 lbs, < 16 oz).
+
+---
+
+## Test Data Requirements
+
+### Prerequisites
+- Test user with DataEntry role
+- Valid PC1 IDs in `appsettings.json` under `TestPc1Ids`
+- Cases must have:
+  - At least one existing TCID entry (for Tests 4-9)
+  - Target Child DOB and Intake Date visible on form
+
+### Test Creates
+- New TCID entries (Test 2, Test 3)
+- Medical providers via modal (Test 6)
+- Medical facilities via modal (Test 6)
+
+### Test Modifies
+- Existing TCID entries (Tests 4-9)
+- PHQ-9 scores
+- Additional Items selections
+
+### Test Deletes
+- None
+
+**Net Impact**: Some TCID entries created, some modified.
+
+---
+

+```
+
+---
+
+## Troubleshooting
+
+### Test Fails: "Target Child Information link was not found"
+- **Issue**: Link not in Forms pane or selector changed
+- **Solution**: Verify Forms tab loaded, check link selector
+
+### Test Fails: "TCID grid was not found"
+- **Issue**: Page didn't load or no TCID entries exist
+- **Solution**: Verify case has at least one TCID entry, check grid selector
+
+### Test Fails: Birth weight validation doesn't appear
+- **Issue**: Values are actually within valid range
+- **Solution**: Verify test values are >= 17 lbs or >= 16 oz
+
+### Test Fails: Health insurance checkboxes not disabled
+- **Issue**: Medicaid dropdown selection didn't trigger update
+- **Solution**: Increase wait time after Medicaid selection, verify page refresh
+
+### Test Fails: Medical provider modal validation not appearing
+- **Issue**: Validation logic changed or selector incorrect
+- **Solution**: Verify modal validation selector, check required fields
+
+### Test Fails: PHQ scores not calculating
+- **Issue**: JavaScript not running or scores not set correctly
+- **Solution**: Verify all 9 dropdowns set, increase wait time for calculation
+
+### Test Fails: Prenatal care date validation appears unexpectedly
+- **Issue**: Target Child DOB changed or test date is actually after birth
+- **Solution**: Verify Target Child DOB, adjust test dates accordingly
+
+### Test Fails: Tab switch doesn't work
+- **Issue**: Tab selector changed or JavaScript not loaded
+- **Solution**: Verify tab selectors, check for JavaScript errors
+
+### Test Fails: "Other specify" input not visible
+- **Issue**: "Other" option not triggering show/hide logic
+- **Solution**: Verify "Other" value is correct, increase wait time after selection
