Java + Selenium automated testing study (three) - assertion

1, modified Login class added assertions;

　　Assertion: Check our operating results pages get is consistent with the results we expected.

2, using the xml file to run all the test classes;

Login class two test write:

package com.test;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.Assert;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.Test;

public class Login  {
    Driver the WebDriver = null ;
     // call the method of positioning elements 
    ElementLocation elementLocation =   new new ElementLocation ();
     // run before running a method 
    @BeforeMethod
     public  void before () {
        System.setProperty("webdriver.chrome.driver", "E:\\selenium\\chromedriver.exe");
        driver = new ChromeDriver();
        String url = "http://xadev.alsolife.com/";
        driver.manage().window().maximize();
        driver.get(url);
    }
    /**
     * Positioning login interface elements
     * 1. Enter the correct phone number
     * 2. Enter the correct password
     * 3. Log success
     */
//    @Test
//    public void test_login1(){
//        elementLocation.findElementByCssClearSendkeys("input[type='text']","15211111111",driver);
//        elementLocation.findElementByCssClearSendkeys("input[type='password']","123456",driver);
//        elementLocation.findElementByCssClick("button[type='button']",driver);
//        System.out.println("登录成功,跳转到首页");
//    }

    // enter the wrong user name 
    @Test
     public  void test_login2 () {
        String phone = "153";
        elementLocation.findElementByCssClearSendkeys("input[type='text']",phone,driver);
        elementLocation.findElementByCssClick("button[type='button']",driver);
　　　　　//加入断言
        try{
            Assert.assertEquals(phone,"15211111111");
        }catch(AssertionError e){
           System.out.println ( "incorrect phone number format:" + e.getMessage ());
        }
    }
    // do not enter the phone number 
    @Test
     public  void test_login3 () {
        Phone String = "" ;
         // enter the phone number 
        elementLocation.findElementByCssClearSendkeys ( "the INPUT [of the type = 'text']", Phone , Driver);
         // Click Login 
        elementLocation.findElementByCssClick ( "the Button [of the type = 'the Button']" , Driver);
         the try {
            Assert.assertEquals(phone,"15211111111");
        }catch (AssertionError e){
            System.out.println ( "phone number can not be empty" + e.getMessage ());
        }
    }
    // run after completion of a method of operating 
    @AfterMethod
     public  void After () {
         the try {
            Thread thread = new Thread();
            thread.sleep(5000);
        }catch (InterruptedException e){
           e.printStackTrace ();
        }
        driver.quit();
    }
}

TestSuit.xml create a file (name easily play):

<suite name="TestSuite Demo">
    <test name="TestSuite Demo Test">
        <classes>
            <! - execute test case class -> 
　　　　　　　<- name:! Encased executive class 
　　　　　　　　　　<class> have more ->
            <class name="com.test.Login"></class>
        </classes>
    </test>
</suite>

Run directly TestSuit.xml a file, the Login class.

Results are as follows:

 

 

 content:

1, TestNG assert methods commonly used:

　　assertEquals (String actual, String expected) // determine the true value of the expected values ​​are equal, if not equal the test fails will throw an exception

       assertEqual (Actual String, String expected, Stringmessage)  // check if two strings are equal, if not equal, the test failed, and throw in the third message parameter information we provide exceptions to print out

　　assertTrue (boolean condition) // if the value is true, by the use cases, or throw an exception AssertionError

　　assertFalse(boolean condition)

2, the order of execution of the test cases, Login class two test cases: test_login2, test_login3

　　Generally based on character ordering, if the same character in digital sort.

 

Talk about the previous question:

1, before the date, success has not been saved, because the button element positioned the wrong way:

          Before writing: driver.findElement (By.ByXPath.xpath ( " (// Button [@ type = 'Button']) [. 1]") ) .click ();

　　  改正之后：    driver.findElement(By.ByXPath.xpath("//button[contains(@class,'submit-infor')]")).click();

Always I thought it was the wrong date positioned elements have been modified, and finally found the button is positioned incorrectly, but there are doubts: other content can not successfully saved to date.
