[shivani1309]

Below is the scenario i want to read the data from Csv

Scenario Outline: successful signup
Given I'm on "https://github.com/join" page
When I type "" in the "<username_field>" input field
When I type "" in the "<email_field>" email field
When I type "" in the "<password_field>" password field
When I type "<conf_pass>" in the "<confpass_field>" confirm field
When I will click on "<ok_field>" button
Then I should see "Welcome to GitHub" in label "<welcome_msg_field>"
Examples:
|username|username_field | email |email_field |password|password_field|conf_pass|confpass_field|ok_field|welcome_msg_field|
|file:testdata/SignUpData.csv|.//[@id='user_login']|cwmsy117@gmail.com117|.//[@id='user_email']|Cwms123456|.//[@id='user_password']|Cwms123456|.//[@id='user_password_confirmation']|signup_button|.//*[@id='site-container']/div/div[1]/h1|
