# 🔍 smart-locators-playwright

**A smart, resilient way to locate elements in Playwright for Python — reduce flakiness, simplify locators, and write cleaner test code. - Now with self-healing capabilities**

[![PyPI version](https://badge.fury.io/py/smart-locators-playwright.svg)](https://pypi.org/project/smart-locators-playwright/)

## 🚀 What is it?

`smart-locators-playwright` is a utility wrapper around Playwright’s native locator system. It allows you to define **multiple locator strategies at once**, and it will **automatically try each until one succeeds** — no more writing fallback logic or suffering flaky tests due to minor DOM changes.

## Why Smart Locators?

Element location is often the most brittle part of web automation. Web UIs change frequently, and a single broken locator can cascade failures across your entire test suite. Smart Locators solves this by providing:

- **Unified API**: One simple `find()` method instead of chaining multiple Playwright methods
- **Automatic Fallback Strategy**: Tries multiple locators in sequence until one succeeds — your tests survive minor DOM changes
- **Custom Attribute Support**: Locate elements by any HTML attribute (data attributes, custom attributes, etc.) automatically converted to XPath
- **Reduced Maintenance**: When UI changes occur, your tests can still pass using fallback locators instead of requiring immediate refactoring
- **Both Sync & Async Support**: Works seamlessly with both `playwright.sync_api` and `playwright.async_api`
## Installation

Install smart-locators-playwright with pip

```bash
  pip install smart-locators-playwright
```
    

## ✅ Key Features

### 1. 🔗 Unified Element Location API

Instead of writing multiple locator calls and chaining methods:

```python
# Traditional Playwright approach (brittle)
element = page.get_by_role("button") ## Find an element by role
element_2 = page.locator("//button[@id='submit_btn']") ## Find an element using xpath
```

Use a single, intuitive `find()` method that accepts multiple strategies:

```python
# Smart Locators approach (resilient)
element = smart.find(id="submit", text="Submit", role="button")
```

This is cleaner, more readable, and handles all the fallback logic internally.

---

### 2. 🧩 Multiple Location Strategies

The `find()` method supports all standard Playwright locators, plus custom strategies:

#### ✅ Built-in Playwright Strategies:
- `id`: Element ID attribute
- `text`: Text content
- `role`: ARIA role
- `label`: Associated label text
- `placeholder`: Placeholder text
- `alt`: Alt text (for images)
- `title`: Title attribute

#### 🛠️ Additional Custom Strategies:
- `name`: Name attribute
- `css`: CSS selector
- `xpath`: XPath expression
- `any other attribute`: Will be auto-converted to XPath

---

### 3. 🔄 Automatic Fallback Strategy

Locators are tried sequentially until one succeeds. This makes your tests **resilient to DOM changes** without requiring test refactoring:

```python
# Will try: id → name → text (in that order)
element = smart.find(id="loginBtn", name="submitLogin", text="Login")
```

If the element's `id` changes or is removed, the library automatically falls back to the `name` attribute, then the text content. Your test remains stable despite UI modifications.

---

### 4. 👥 Support for Multiple Elements

By default, `find()` returns the first matching element. Set `first_match=False` to retrieve all matching elements:

```python
# Get the first matching button (default)
button = smart.find(role="button", first_match=True)
button.click()

# Get all matching buttons as a Locator collection
all_buttons = smart.find(role="button", first_match=False)

# Iterate through all buttons
for button in all_buttons.all():
    print(button.text_content())
```

---

### 5. 🔧 Self-Healing Locators

Smart Locators can automatically **extract and store element attributes** after finding them. This enables a self-healing mechanism where you can maintain a centralized locator repository and easily update locators when your application changes.

```python
# Enable self-healing: automatically save element attributes to a JSON file
element = smart.find(
    id="submit-btn",
    name="submit",
    text="Submit",
    first_match=True,
    locator_update=True,  # Enable locator extraction
    element_name="submit_button",  # Name for the locator entry
    locators_file="./locators/app_locators.json"  # Where to save the locators
)

element.click()
```

When `locator_update=True`, the found element's HTML attributes are automatically extracted and saved to the specified JSON file. This creates a reusable locator repository that can be updated over time, reducing maintenance overhead when your application's UI evolves.

When the generated locator JSON file is reused as the locator source in subsequent test runs, the stored attributes act as fallback locator variables, enabling a self-healing mechanism when primary locators change.

**Generated JSON file example:**
```json
{
  "submit_button": {
    "id": "submit-btn",
    "class": "btn btn-primary",
    "type": "button",
    "data-testid": "submit-button",
    "aria-label": "Submit form"
  }
}
```

This feature is particularly useful for:
- Maintaining a centralized locator library
- Documenting all available attributes for each element
- Making updates quick and painless when the UI changes
- Sharing locators across multiple test files

## Usage/Examples

```python
## Finding single element

from playwright.sync_api import sync_playwright
from smart_locators_playwright import SmartLocators

with sync_playwright() as p:
    browser = p.chromium.launch()
    page = browser.new_page()
    page.goto("https://example.com")

    smart = SmartLocators(page)

    # Try locating using multiple strategies
    element = smart.find(
        id="submit-btn",
        name="submit",
        text="Submit",
        role="button",
        first_match=True  # Stop at the first successful match
    )

    element.click()
    browser.close()

```


```python
## Finding multiple element

# Return all matching elements instead of just the first
buttons = smart.find(
    role="button",
    first_match=False
)

# Iterate through elements
for button in buttons:
    print(button.text_content())
```

```python
## Custom Attributes

# Find by data attributes or any custom attribute
element = smart.find(
    data_testid="submit-button",  # Converted to XPath
    data_cy="login"               # Converted to XPath
)
```

```python
## Combining with Playwright's Chain API
## The returned object is a standard Playwright Locator that can be further refined:

# Find a button inside a specific container
button = smart.find(role="button", text="Submit").filter(has_text="Submit")
```

```python
# Find all rows in a table
rows = smart.find(
    css="table#users tr",
    first_match=False
)

# Process each row
for row in rows.all():
    username = row.locator("td").nth(0).text_content()
    email = row.locator("td").nth(1).text_content()
    print(f"User: {username}, Email: {email}")
```
