Find element by link text in Selenium Python - Test Execution Trace

Test Overview

This test opens a web page and finds a link using its visible text. It then clicks the link and verifies the new page title to confirm navigation.

Test Code - Selenium

Selenium Python

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import unittest

class TestFindByLinkText(unittest.TestCase):
    def setUp(self):
        self.driver = webdriver.Chrome()
        self.driver.get('https://example.com')

    def test_click_link_by_text(self):
        driver = self.driver
        # Wait until the link with text 'More information...' is present
        link = WebDriverWait(driver, 10).until(
            EC.presence_of_element_located((By.LINK_TEXT, 'More information...'))
        )
        link.click()
        # Wait for the new page title to contain 'IANA'
        WebDriverWait(driver, 10).until(EC.title_contains('IANA'))
        self.assertIn('IANA', driver.title)

    def tearDown(self):
        self.driver.quit()

if __name__ == '__main__':
    unittest.main()

Execution Trace - 6 Steps

Step	Action	System State	Assertion	Result
1	Test starts and Chrome browser opens	Browser window opens at https://example.com homepage	—	PASS
2	Wait until link with text 'More information...' is present	Page loaded with visible link text 'More information...'	Check presence of link element by link text	PASS
3	Click the link found by link text	Browser navigates to linked page	—	PASS
4	Wait until page title contains 'IANA'	New page loaded with title containing 'IANA'	Verify page title contains 'IANA'	PASS
5	Assert that 'IANA' is in the page title	Page title is 'IANA — IANA-managed Reserved Domains' or similar	assertIn('IANA', driver.title)	PASS

Failure Scenario

Failing Condition: Link with text 'More information...' is not found within 10 seconds

Execution Trace Quiz - 3 Questions

What method is used to find the link element in this test?

A find_element(By.CLASS_NAME, 'More information...')

B find_element(By.LINK_TEXT, 'More information...')

C find_element(By.ID, 'More information...')

D find_element(By.CSS_SELECTOR, 'a[href]')

Key Result

Use explicit waits to find elements by visible link text to ensure the element is present before interacting, improving test reliability.

Practice

1. What does the Selenium method find_element_by_link_text do?

easy

A. It finds elements by their CSS class name.

B. It finds any element by its HTML tag name.

C. It finds a link on the page by its exact visible text.

D. It finds elements by their XPath expression.

Solution

1. Step 1: Understand the method purpose

   find_element_by_link_text specifically searches for anchor (<a>) elements by their visible text on the page.

2. Step 2: Compare with other locator types

   Other methods like finding by tag name, class name, or XPath do not focus on link text but on different attributes or structures.

3. Final Answer:

   It finds a link on the page by its exact visible text. -> Option C

4. Quick Check:

   find_element_by_link_text = exact link text match [OK]

Hint: Link text locator matches exact visible text only [OK]

Common Mistakes:

• Confusing link text with partial text
• Using it to find non-link elements
• Assuming it matches partial text automatically

2. Which of the following is the correct syntax to find a link with text "Home" using Selenium in Python?

easy

A. driver.find_element_link_text("Home")

B. driver.find_element_by_link("Home")

C. driver.find_element_by_text_link("Home")

D. driver.find_element_by_link_text("Home")

Solution

1. Step 1: Recall Selenium method naming

   The correct method to find a link by its exact text is find_element_by_link_text.

2. Step 2: Check method call syntax

   The method is called on the driver object with the link text as a string argument, e.g., driver.find_element_by_link_text("Home").

3. Final Answer:

   driver.find_element_by_link_text("Home") -> Option D

4. Quick Check:

   Correct method name and syntax = driver.find_element_by_link_text("Home") [OK]

Hint: Remember full method name: find_element_by_link_text [OK]

Common Mistakes:

• Using incomplete or incorrect method names
• Missing parentheses or quotes
• Confusing with other locator methods

3. What will be the output of the following code snippet if the page contains a link with text exactly "Contact Us"?

element = driver.find_element_by_link_text("Contact Us")
print(element.tag_name)

medium

A. a

B. div

C. span

D. NoSuchElementException

Solution

1. Step 1: Understand what find_element_by_link_text returns

   This method returns the anchor (<a>) element whose visible text matches exactly "Contact Us".

2. Step 2: Check the tag name of a link element

   Links in HTML are represented by the <a> tag, so element.tag_name will be "a".

3. Final Answer:

   a -> Option A

4. Quick Check:

   Link tag name = "a" [OK]

Hint: Link elements always have tag name 'a' [OK]

Common Mistakes:

• Assuming tag name is 'div' or 'span'
• Expecting text output instead of tag name
• Not handling exceptions if link missing

4. Given the code below, what is the error and how to fix it?

element = driver.find_element_by_link_text('About')
print(element.text)

Assume the link text on the page is "About Us".

medium

A. SyntaxError due to missing parentheses; fix by adding parentheses.

B. NoSuchElementException because link text does not match exactly; fix by using full text "About Us".

C. AttributeError because element has no text attribute; fix by using element.get_text().

D. No error; code works fine.

Solution

1. Step 1: Check link text matching requirement

   The method find_element_by_link_text requires exact visible text match. "About" does not match "About Us" exactly.

2. Step 2: Identify the error and fix

   Because of mismatch, Selenium raises NoSuchElementException. Fix is to use the exact link text: 'About Us'.

3. Final Answer:

   NoSuchElementException because link text does not match exactly; fix by using full text "About Us". -> Option B

4. Quick Check:

   Exact text match needed = NoSuchElementException because link text does not match exactly; fix by using full text "About Us". [OK]

Hint: Link text must match exactly, no partial matches [OK]

Common Mistakes:

• Using partial link text with find_element_by_link_text
• Confusing element.text with get_text()
• Ignoring exception when element not found

5. You want to click a link that has the visible text "Learn More" but sometimes the link text changes to "Learn More About Us". How can you reliably find and click this link using Selenium in Python?

hard

A. Use find_element_by_partial_link_text("Learn More") to match both variations.

B. Use find_element_by_link_text("Learn More") only and ignore other cases.

C. Use find_element_by_id("learnMoreLink") assuming the link has an id.

D. Use find_element_by_tag_name("a") and click the first link.

Solution

1. Step 1: Understand the problem with exact link text

   Since the link text changes between "Learn More" and "Learn More About Us", exact match with find_element_by_link_text will fail for one variation.

2. Step 2: Use partial link text locator

   find_element_by_partial_link_text("Learn More") matches any link containing "Learn More", covering both cases reliably.

3. Step 3: Consider other options

   Using id requires knowing the id attribute, which may not exist. Clicking the first <a> tag is unreliable and may click wrong link.

4. Final Answer:

   Use find_element_by_partial_link_text("Learn More") to match both variations. -> Option A

5. Quick Check:

   Partial link text matches multiple variations [OK]

Hint: Partial link text finds links with text containing given string [OK]

Common Mistakes:

• Using exact link text when text varies
• Assuming link has id without checking
• Clicking first link without filtering
