How can I troubleshoot and resolve the issue of “the import org.openqa cannot be resolved”?

In the context of selenium, here is the example given of how you can design and implement the test cases by using the selenium library in the robot framework for testing a login functionality:-

Test cases for successful login:-

*** Test Cases ***

Successful Login Test

    Open Browser    https://yourwebsite.com    chrome

    Input Text    username_field    ${valid_username}

    Input Password    password_field    ${valid_password}

    Click Button    login_button

    Wait Until Page Contains Element    welcome_message

    Page Should Contain    Welcome, ${valid_username}

    Close Browser

Test cases for invalid credentials

*** Test Cases ***

Invalid Credentials Test

    Open Browser    https://yourwebsite.com    chrome

    Input Text    username_field    ${invalid_username}

    Input Password    password_field    ${invalid_password}

    Click Button    login_button

    Page Should Contain Invalid username or password

    Close Browser

Test cases for empty username

*** Test Cases ***

Empty Username Test

    Input Password    password_field    ${valid_password}

    Click Button    login_button

    Page Should Contain Please enter your username

    Close Browser

Test cases for empty password

*** Test Cases ***

Empty Password Test

    Open Browser https://yourwebsite.com chrome

    Input Text    username_field    ${valid_username}

    Click Button    login_button

    Page Should Contain    Please enter your password

    Close Browser

Test cases for forgot password link

*** Test Cases ***

Forgot Password Link Test

    Open Browser    https://yourwebsite.com    chrome

    Click Link    forgot_password_link

    Page Should Contain Forgot Password Page

    Close Browser

Here is the example given of how you can write Python coding by using the Selenium library for automation of the testing the login functionality of a web-based application:-

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

# Initialize the Chrome driver

Driver = webdriver.Chrome()

# Navigate to the login page

Driver.get(https://yourwebsite.com)

# Define valid and invalid credentials

Valid_username = “valid_user”

Valid_password = “valid_pass”

Invalid_username = “invalid_user”

Invalid_password = “invalid_pass”

# Test case for successful login

Def test_successful_login():

    Username_field = driver.find_element_by_id(“username_field”)

    Password_field = driver.find_element_by_id(“password_field”)

    Login_button = driver.find_element_by_id(“login_button”)

    Username_field.send_keys(valid_username)

    Password_field.send_keys(valid_password)

    Login_button.click()

    WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.ID, “welcome_message”)))

    Assert “Welcome, “ + valid_username in driver.page_source

# Test case for invalid credentials

Def test_invalid_credentials():

    Username_field = driver.find_element_by_id(“username_field”)

    Password_field = driver.find_element_by_id(“password_field”)

    Login_button = driver.find_element_by_id(“login_button”)

    Username_field.send_keys(invalid_username)

    Password_field.send_keys(invalid_password)

    Login_button.click()

    Assert “Invalid username or password” in driver.page_source

# Test case for empty username

Def test_empty_username():

    Password_field = driver.find_element_by_id(“password_field”)

    Login_button = driver.find_element_by_id(“login_button”)

    Password_field.send_keys(valid_password)

    Login_button.click()

    Assert “Please enter your username” in driver.page_source

# Test case for empty password

Def test_empty_password():

    Username_field = driver.find_element_by_id(“username_field”)

    Login_button = driver.find_element_by_id(“login_button”)

    Username_field.send_keys(valid_username)

    Login_button.click()

    Assert “Please enter your password” in driver.page_source

# Test case for forgot password link

Def test_forgot_password_link():

    Forgot_password_link = driver.find_element_by_link_text(“Forgot Password?”)

    Forgot_password_link.click()

    Assert “Forgot Password Page” in driver.page_source

# Run the test cases

Test_successful_login()

Test_invalid_credentials()

Test_empty_username()

Test_empty_password()

Test_forgot_password_link()

# Close the browser

Driver.quit()
