What is Minitest?
Minitest is a testing framework for Ruby that provides a complete suite of testing facilities. It is quick to run and supports TDD, BDD, mocking, and benchmarking.
Here is a script using Ruby, Selenium WebDriver and Minitest to assert that the ‘page title’ for the Restful Booker Platform is equal to “Restful-booker-platform demo”.
require 'rubygems'
require "selenium-webdriver"
require 'minitest/autorun'
class Test < Minitest::Test
def test_page_title
#Chrome browser instantiation
driver = Selenium::WebDriver.for :chrome
# maximize the browser window.
driver.manage.window.maximize
#Loading the Restful Booker URL
driver.navigate.to "https://automationintesting.online/#/admin"
# create a wait with a timeout of 15
wait = Selenium::WebDriver::Wait.new(timeout: 15)
# dismiss dropdown
button = wait.until {
element = driver.find_element(:xpath, "//button[text()='Let me hack!']")
element if element.displayed?
}
button.click()
#Populate username
input = wait.until {
element = driver.find_element(:id, "username")
element if element.displayed?
}
input.send_keys("admin")
#Populate password
input = wait.until {
element = driver.find_element(:id, "password")
element if element.displayed?
}
input.send_keys("password")
# click login button
button = wait.until {
element = driver.find_element(:id, "doLogin")
element if element.displayed?
}
button.click()
# assert page title
assert_equal(driver.title, "russmorley.net")
driver.quit
end
end
Result
The test has failed. From the test output below. We can see that the actual page title is “Restful-booker-platform demo”
The assertion made was against “russmorley.net”. The test correctly failed.
Let’s update the assertion in our script to “Restful-booker-platform demo”
require 'rubygems'
require "selenium-webdriver"
require 'minitest/autorun'
class Test < Minitest::Test
def test_page_title
#Chrome browser instantiation
driver = Selenium::WebDriver.for :chrome
# maximize the browser window.
driver.manage.window.maximize
#Loading the Restful Booker URL
driver.navigate.to "https://automationintesting.online/#/admin"
# create a wait with a timeout of 15
wait = Selenium::WebDriver::Wait.new(timeout: 15)
# dismiss dropdown
button = wait.until {
element = driver.find_element(:xpath, "//button[text()='Let me hack!']")
element if element.displayed?
}
button.click()
#Populate username
input = wait.until {
element = driver.find_element(:id, "username")
element if element.displayed?
}
input.send_keys("admin")
#Populate password
input = wait.until {
element = driver.find_element(:id, "password")
element if element.displayed?
}
input.send_keys("password")
# click login button
button = wait.until {
element = driver.find_element(:id, "doLogin")
element if element.displayed?
}
button.click()
# assert page title
assert_equal(driver.title, "Restful-booker-platform demo")
driver.quit
end
end
Result
Success! The test has passed. From the test output below. We can see that the assertion has been made correctly without any failures.
