Use of selenium tools for automated testing

1. The premise of automated testing

1.1 What is automation?

• Reduce labor costs
• Do a lot of repetitive work
• Improve test efficiency
• Ensure consistency of work and increase trust
• Complete work that cannot be done by hand

1.2 Is it suitable for automation?

• Time (long project cycle)
• People (familiar with automation)
• System (the main body of the project is stable)
• Leadership (leadership supports recommended use of automation)

1.3 Under what circumstances do automation

• unit test?
• Integration Testing?
• interface test?
• UI testing

1.4 What kind of projects need to be automated

• Demand changes slowly
• long cycle
• Scripts can be reused

1.5 Selection of automation tools and frameworks

• Selenium Webdriver
• FireBug
• FirePath

2. Introduction to Selenium

2.1 History of Selenium

• A colleague Jason Huggins developed through the js code base to reduce testing work

2.2 Selenium family members

• Selenium RC
• Selenium IDE (automated script recording tool)
• Selenium Webdriver
• Selenium Grid (running scripts in different browsers, etc.)

2.3 How Selenium works

3. Essential tools for automated testing

• Select the Firefox browser, and the version generally chooses between version 27-32
• Install FireBug, FirePath

Installation and use of Selenium IDE

• Install

  

• to record

打开--浏览器顶部-工具-selenium IDE-打开
录制按钮-红色的时候是录用状态
URL
Test Case
操作区域：command操作-target元素-value值

4. Introduction to Selenium IDE installation and use

5. Automated framework environment construction

6. Common browser startup

• firefox start

driver = new FirefoxDriver()
System.setProperty("webdriver.firefox.bin", "E:/Firefox/firefox.exe")

• Chrome starts

driver = new ChromeDriver();
System.setProperty("webdriver.chrome.driver", "E:/webdriver/chromedriver/chromedriver.exe")

• IE starts
  • Need to download the driver

• driver = new InterExplorerDriver();
  System.setProperty("webdriver.ie.driver", "E:/webdriver/iedriverserver/IEDriverServer.exe")
  

Webdriver common element positioning

1. By.id
2. By.name
3. By.tagName
4. By.tagName
5. By.className
6. By.linkText
7. By.partialLinkText
8. By.xpath
9. By.css
10. table

Common API modules:

1. Open URL API.

   • Driver.get()
   • Driver.navigate.to()

2. Manipulating the browser API

   • Driver.navigate().refresh Refresh
   • Driver.navigate().forward
   • Driver.navigate().back backwards
   • Driver.getTitle() prints the title
   • Driver.getCurrentUrl() Get the current URL address
   • Driver.manage().window().maximize()Browser size - - - - - Driver.quit Exit and close the browser without closing the process
   • Driver.close() closes the browser, closes the process, operates the scroll bar through Js, operates the browser cookie) 

3. Input box operation API

   • Send Keys()
   • Clear()
   • getText()
   • Click()

4. Select Box Handling

   • Single box
   • check box
   • drop down box
   • iframe window handling
   • Pop-up processing

5. Handling of page elements

   • waiting to load
   • Obtain the css attribute of the object by obtaining the element value according to the attribute
   • Obtain object status: whether the page displays isdisplay
   • Whether the element exists find_element
   • Whether the element is selected isSelected()
   • Whether it is in grayed state idEnabled
   • Special operation explanation:
     • The error is saved as a screenshot
     • Simulate right mouse button
     • mouseover
     • upload files
     • Date Control Handling
     • Browser scroll bar operation
