## 2. UI5 Control Type Knowledge

### 2.1 Top 20 Controls (Typed Proxy Priority)

These are the most-used controls in SAP Fiori apps. Each gets a typed proxy in `src/proxy/typed/` (note: this directory exists but is empty in v1.0 — typed proxies are planned for v1.1):

| #   | Control                             | Key Methods                            | Key Properties                                              | Events                    |
| --- | ----------------------------------- | -------------------------------------- | ----------------------------------------------------------- | ------------------------- |
| 1   | `sap.m.Button`                      | `press()`                              | `text`, `icon`, `enabled`, `type`                           | `press`                   |

| 17  | `sap.m.MultiInput`                  | `addToken()`, `getTokens()`            | `tokens`, `value`                                           | `tokenUpdate`             |
| 18  | `sap.f.DynamicPage`                 | N/A                                    | `headerExpanded`, `showFooter`                              | —                         |
| 19  | `sap.m.OverflowToolbar`             | `getContent()`                         | `content` (aggregation)                                     | —                         |
| 20  | `sap.ui.comp.smarttable.SmartTable` | `rebindTable()`                        | `entitySet`, `tableType`                                    | `dataReceived`            |

### 2.2 Control Hierarchy

```text
sap.ui.core.Element
└── sap.ui.core.Control
    ├── sap.m.Button
    ├── sap.m.InputBase
    │   ├── sap.m.Input
    │   ├── sap.m.TextArea
    │   ├── sap.m.DatePicker
    │   ├── sap.m.ComboBox
    │   ├── sap.m.MultiInput
    │   └── sap.m.SearchField
    ├── sap.m.ListBase
    │   ├── sap.m.List
    │   └── sap.m.Table
    ├── sap.m.Select

    ├── sap.f.DynamicPage
    ├── sap.ui.table.Table (different from sap.m.Table!)
    └── sap.ui.comp.smarttable.SmartTable
```

### 2.3 Control Resolution Strategies

```text
Strategy 1: ElementRegistry (UI5 ≥ 1.108) — PREFERRED
  sap.ui.require(['sap/ui/core/ElementRegistry'], (Reg) => Reg.get(id))

Strategy 2: Core.byId (all versions)
  sap.ui.getCore().byId(id)

Strategy 3: Element.getElementById (deprecated, fallback)
  sap.ui.core.Element.getElementById(id)

Strategy 4: RecordReplay (property-based, no ID needed)
  sap.ui.test.RecordReplay.findDOMElementByControlSelector({
    controlType: 'sap.m.Button',
    properties: { text: 'Save' }
  })
```

---

## 3. RecordReplay API Knowledge

### 3.1 What It Is

RecordReplay is SAP's official automation API (`sap.ui.test.RecordReplay`). It provides:

- `findDOMElementByControlSelector()` — find DOM element by UI5 control properties
- `interactWithControl()` — interact using SAP's recommended interaction method
- `findAllDOMElementsByControlSelector()` — find multiple matches

### 3.2 Selector Format (SAP RecordReplay)

```javascript
// RecordReplay selector — this is what gets passed to findDOMElementByControlSelector
const selector = {
  controlType: 'sap.m.Button',
  properties: {
    text: 'Save',
  },
  ancestor: {
    controlType: 'sap.m.Dialog',
    properties: { title: 'Create Purchase Order' },
  },
  interaction: {
    idSuffix: 'inner', // Target specific DOM element within the control
  },
};
```

### 3.3 Interaction via RecordReplay

```javascript
// OPA5-style interaction (used by OPA5 interaction strategy)
sap.ui.test.RecordReplay.interactWithControl({
  selector: {
    controlType: 'sap.m.Button',
    properties: { text: 'Save' },
  },
  interactionType: 'Press',
});

// Interaction types: 'Press', 'EnterText', 'Scroll'
```

### 3.4 RecordReplay Limitations

| Limitation                            | Workaround                                              |
| ------------------------------------- | ------------------------------------------------------- |
| Cannot interact with non-UI5 elements | Use Playwright native for non-UI5 DOM                   |
| No support for drag-and-drop          | Use Playwright's `page.mouse` API                       |
| Limited to visible controls           | Set `preferVisibleControls: true` (D25)                 |
| Performance overhead on large pages   | Cache control handles, batch operations                 |
| No Web Component support              | Use Playwright's shadow DOM locators (`>>>` combinator) |

## 4. SAP Authentication Flows

### 4.1 BTP SAML (Most Common)

```text
Browser → BTP Login Page (SAP IAS / Azure AD / custom IDP)
  → POST credentials
  → SAML assertion → redirect to FLP
  → Session cookie stored in storageState
```

```typescript
// auth.setup.ts — produces storageState for downstream tests (D28)
import { test as setup } from '@playwright/test';

setup('SAP BTP SAML Authentication', async ({ page }) => {
  // 1. Navigate to SAP system
  await page.goto(process.env.SAP_CLOUD_BASE_URL!);

  // 2. Wait for login page
  await page.waitForSelector('#j_username, #USERNAME_FIELD, input[name="loginfmt"]');

  // 3. Fill credentials
  await page.fill('#j_username', process.env.SAP_CLOUD_USERNAME!);
  await page.fill('#j_password', process.env.SAP_CLOUD_PASSWORD!);

  // 4. Submit
  await page.click('#logOnFormSubmit, #LOGIN_LINK');

  // 5. Wait for FLP shell
  await page.waitForSelector('.sapUshellShellHead', { timeout: 30_000 });

  // 6. Save session
  await page.context().storageState({ path: '.auth/sap-session.json' });
});
```

### 4.2 Authentication in Praman

Praman v1.0 handles authentication via `SAPAuthHandler` from `playwright-praman/auth`,
configured through `AuthConfig` in the Praman config. Authentication is performed in
seed/setup scripts (not in test bodies) and session state is persisted via Playwright's
`storageState` mechanism. See `skills-sap-fiori-consultant.md` Section 4 for detailed
auth patterns.

---

## 5. FLP Navigation Patterns

### 5.1 Tile Navigation

```typescript
// FLP tile click — navigate by tile header text
async openTileByTitle(page: Page, title: string): Promise<void> {
  // Find tile using RecordReplay
  const tile = await page.evaluate(
    ({ tileTitle }) => {
      return sap.ui.test.RecordReplay.findDOMElementByControlSelector({
        controlType: 'sap.m.GenericTile',
        properties: { header: tileTitle },
      });
    },
    { tileTitle: title },
  );

  // Click the tile
  await page.locator(`#${tile.id}`).click();

  // Wait for app to load
  await waitForUI5Stable(page);
}
```

### 5.2 Intent Navigation

```typescript
// Navigate by semantic object + action (SAP intent-based navigation)
// URL format: #SemanticObject-action?param=value
async navigateByIntent(
  page: Page,
  semanticObject: string,
  action: string,
  params?: Record<string, string>,
): Promise<void> {
  const hash = `#${semanticObject}-${action}`;
  const queryString = params
    ? '?' + new URLSearchParams(params).toString()
    : '';

  await page.evaluate(
    ({ intent }) => {
      sap.ushell.Container.getServiceAsync('CrossApplicationNavigation')
        .then(service => service.toExternal({ target: { shellHash: intent } }));
    },
    { intent: hash + queryString },
  );

  await waitForUI5Stable(page);
}
```

## 6. OData Knowledge

### 6.1 V2 vs V4 Differences

| Aspect      | OData V2                                        | OData V4                                   |
| ----------- | ----------------------------------------------- | ------------------------------------------ |
| Model class | `sap.ui.model.odata.v2.ODataModel`              | `sap.ui.model.odata.v4.ODataModel`         |
| Read        | `model.read(path, { success, error })`          | `binding.requestObject()` → Promise        |
| Create      | `model.create(path, data, { success, error })`  | `listBinding.create(data)` → Promise       |
| Batch       | `model.setDeferredGroups()` + `submitChanges()` | Automatic batching with `$auto` group      |
| CSRF        | `model.refreshSecurityToken()`                  | Handled automatically                      |
| Metadata    | `model.getMetaModel().getObject(path)`          | `model.getMetaModel().requestObject(path)` |

### 6.2 OData Fixture API

Praman v1.0 provides OData operations through the `ui5.odata.*` fixture methods:

| Method               | Signature                                                     | Purpose                 |
| -------------------- | ------------------------------------------------------------- | ----------------------- |
| `getModelData`       | `getModelData(path, opts?)`                                   | Read model data at path |
| `getModelProperty`   | `getModelProperty(path, opts?)`                               | Read a single property  |
| `queryEntities`      | `queryEntities(serviceUrl, entitySet, opts?)`                 | Query entity set        |
| `createEntity`       | `createEntity(serviceUrl, entitySet, data, opts?)`            | Create entity           |
| `updateEntity`       | `updateEntity(serviceUrl, entitySet, key, data, opts?)`       | Update entity           |
| `deleteEntity`       | `deleteEntity(serviceUrl, entitySet, key, opts?)`             | Delete entity           |
| `callFunctionImport` | `callFunctionImport(serviceUrl, fn, params?, method?, opts?)` | Call function import    |

## 7. Browser Script Expertise

### 7.1 Scripts You Must Help Write

| Script                     | Purpose                                          | File                      |
| -------------------------- | ------------------------------------------------ | ------------------------- |
| `inject-ui5.ts`            | Set up `window.__praman_*` bridge globals        | `bridge/browser-scripts/` |
| `find-control.ts`          | 3-tier control lookup with RecordReplay fallback | `bridge/browser-scripts/` |
| `find-control-fn.ts`       | Function-based control finder                    | `bridge/browser-scripts/` |
| `find-control-matchers.ts` | Control matching utilities                       | `bridge/browser-scripts/` |
| `execute-method.ts`        | Control method execution                         | `bridge/browser-scripts/` |
| `execute-method-fn.ts`     | Function-based method execution                  | `bridge/browser-scripts/` |
| `inspect-control.ts`       | Control property inspection                      | `bridge/browser-scripts/` |
| `get-version.ts`           | Detect UI5 version and rendering mode            | `bridge/browser-scripts/` |
| `get-selector.ts`          | Reverse-engineer selector from DOM element       | `bridge/browser-scripts/` |
| `object-map.ts`            | Browser-side UUID→object storage with cleanup    | `bridge/browser-scripts/` |

### 7.2 Browser Script Rules

```javascript
// ✅ CORRECT: Self-contained, no Node.js imports
function __praman_getById(id) {
  // Tier 1: ElementRegistry (UI5 1.108+)
  try {
    const ElementRegistry = sap.ui.require('sap/ui/core/ElementRegistry');
    if (ElementRegistry) return ElementRegistry.get(id);
  } catch (e) {
    /* fall through */
  }

  // Tier 2: Core.byId
  try {
    return sap.ui.getCore().byId(id);
  } catch (e) {
    /* fall through */
  }

  // Tier 3: Element.getElementById (deprecated)
  try {
    return sap.ui.core.Element.getElementById(id);
  } catch (e) {
    /* fall through */
  }

  return undefined;
}
```

### 7.3 waitForUI5Stable Pattern

```javascript
// Browser-side: check if UI5 is done rendering
function __praman_isUI5Stable() {
  try {
    // Check 1: UI5 Core is initialized
    if (!sap?.ui?.getCore) return false;

    // Check 2: No pending async operations
    const core = sap.ui.getCore();
    if (core.getUIDirty?.()) return false;

    // Check 3: No pending XHR requests (OData)
    if (typeof sap.ui.test?.RecordReplay?.waitForUI5 === 'function') {
      await sap.ui.test.RecordReplay.waitForUI5();
      return true; // UI5 is idle
    }

    // Check 4: No pending timeouts from UI5
    return true;
  } catch (e) {
    return false;
  }
}
```

---

## 8. Web Component Knowledge (Hybrid Apps)

### 8.1 Interaction Strategy by Control Type

Praman uses a single interaction strategy with smart routing — no adapter abstraction.
Classic UI5 controls use RecordReplay selectors. Web Components use Playwright's
shadow DOM locators.

```text
Classic UI5: sap.m.*, sap.ui.core.*, sap.ui.table.* → RecordReplay selectors
Web Components: ui5-button, ui5-input, ui5-table → Playwright shadow DOM locators
Hybrid: Mix of both (e.g., FLP shell is classic, embedded app is WC) → smart routing
```

### 8.2 Web Component Interaction

```typescript
// Web Components use Shadow DOM — cannot use regular selectors
// Use Playwright's built-in shadow DOM support:
await page.locator('ui5-button[text="Save"]').click();
await page.locator('ui5-input').fill('value');

// For custom Web Components with deep shadow:
await page.locator('ui5-table').locator('>>> ui5-table-row').first();
```

## 9. SAP-Specific Anti-Patterns

| Anti-Pattern                                 | Why It's Wrong                          | Correct Pattern                            |
| -------------------------------------------- | --------------------------------------- | ------------------------------------------ |
| `sap.ui.getCore().byId()` in bridge scripts  | Not version-safe, duplicated            | Use `__praman_getById()` (D19)             |
| Hardcoded control IDs (`__button0`)          | IDs are generated, change between views | Use `controlType` + `properties` selectors |
| `page.waitForTimeout(5000)` after navigation | Flaky, wastes time                      | Use `waitForUI5Stable()`                   |
| Direct DOM manipulation                      | Bypasses UI5 framework                  | Use `fireEvent()` or RecordReplay          |
| `document.querySelector('.sapMBtn')`         | CSS class names are internal            | Use RecordReplay or control properties     |
| `eval()` in browser scripts                  | Security violation                      | Use `page.evaluate()` with typed functions |
