95% | [data-testid="submit-btn"] |
| 2nd | data-cy |
90% | [data-cy="login-form"] |
| 3rd | aria-label |
85% | [aria-label="Close dialog"] |
| 4th | role |
80% | [role="button"] |
| 5th | name |
75% | [name="email"] |
| 6th | id |
70% | #username |
| 7th | text |
60% | text="Sign In" |
📱 Mobile Selector Priority

Traditional Approach vs. Best Locator
See why traditional selector generators fail and how Best Locator solves it for both web and mobile
Traditional Generators
The broken approach: Immediate capture on static pages with unreliable selectors
# Typical output from traditional tools
# Web:
await page.locator('#user-name-input-field-123')
await page.locator('.MuiButton-containedPrimary-456')
await page.locator('div:nth-child(3) > input:nth-child(2)')
# Mobile:
driver.find_element(By.XPATH, "//android.widget.Button[1]")
driver.find_element(By.CLASS_NAME, "android.widget.EditText")
❌ Forced immediate capture - No time to navigate or authenticate
❌ Static snapshots - Can't handle login flows or dynamic content
❌ CSS-dependent selectors - Break when styling changes
❌ Generated IDs - Change with every deployment
❌ Brittle XPath - Fragile to DOM/view hierarchy changes
❌ No cross-platform support - Separate tools for web and mobile
❌ No context awareness - Elements captured without proper state
Best Locator
The professional approach: Organic navigation with testing-specific attributes
# Professional output from Best Locator
# Web:
await page.locator('[data-test="username"]')
await page.locator('[data-testid="login-button"]')
await page.locator('[aria-label="Submit form"]')
# Mobile:
driver.find_element(AppiumBy.ID, "com.app:id/username")
driver.find_element(AppiumBy.ACCESSIBILITY_ID, "Submit")
✅ Organic navigation - Browse naturally, login, navigate multiple pages/screens
✅ Cross-platform support - Web (toggle mode) and Mobile (visual inspector)
✅ AI-powered optimization - OpenAI & Ollama integration for intelligent suggestions
✅ Testing-first selectors - Platform-specific stable attributes
✅ 95% confidence rating - Industry-leading reliability
✅ Multi-page/screen sessions - Capture from different views in one session
✅ Context-aware capture - Elements captured in their proper state
✅ Universal framework support - Web + Mobile with all major languages
