Selenium automated Web-based testing

1. Download necessary tools and jar packages

1. Download and install Firefox

(1) download selenium ide

Http://release.seleniumhq.org/selenium-ide/1.9.0/selenium-ide-1.9.0.xpi

(2) download test suite batch Converter

Https://addons.mozilla.org/en-US/firefox/addon/test-suite-batch-converter-sel/

(3) install the Firefox plug-in

Drag the attachment to be installed to Firefox to install it.

2. Download The selenium-server-standalone-2.28.0.jar from the address below, which is used to publish commands to Firefox.

Http://seleniumhq.org/download/

Ii. Record the script and convert it into a Java Script

1. Recording script.

Open the Firefox browser and enable selenium ide such

By default, recording is enabled. Selenium records any operations on Firefox. For example, enter "www.baidu.com" in Firefox and search

"Selenium", such

Selenium ide Interface

Click the button selected in the red box to stop recording the script.

Click the files in selenium IDE and select export test case as --- Java JUnit 4/Web driver. Here I select the Java unit test script.

Save the name. The Code is as follows:

Package COM. example. tests; import Java. util. regEx. pattern; import Java. util. concurrent. timeunit; import Org. JUnit. *; import static Org. JUnit. assert. *; import static Org. hamcrest. corematchers. *; import Org. openqa. selenium. *; import Org. openqa. selenium. firefox. firefoxdriver; import Org. openqa. selenium. support. UI. select; public class test {private WebDriver driver; private string baseurl; private stringbuffer ve Riicationerrors = new stringbuffer (); @ beforepublic void setup () throws exception {driver = new firefoxdriver (); baseurl = "http://www.baidu.com/"; driver. manage (). timeouts (). implicitlywait (30, timeunit. seconds) ;}@ testpublic void test () throws exception {driver. get (baseurl + "/"); driver. findelement (. ID ("kW ")). clear (); driver. findelement (. ID ("kW ")). sendkeys ("Selenium"); driver. findelement (. ID ("Su ")). Click (); driver. findelement (. linktext ("Selenium _ Baidu Encyclopedia ")). click () ;}@ afterpublic void teardown () throws exception {driver. quit (); string verificationerrorstring = verificationerrors. tostring (); If (! "". Equals (verificationerrorstring) {fail (verificationerrorstring) ;}} private Boolean iselementpresent (by) {try {driver. findelement (by); Return true;} catch (nosuchelementexception e) {return false ;}}}

Create a new Java project, place the code in a new class, and then import the downloaded selenium-server-standalone-2.28.0.ja into the project. The final project structure is as follows:

In Testa. Java, right click --- run as and select JUnit to run.

The test results are as follows:

After the script runs, a Firefox window is automatically opened and then executed in the order of the previous operations.

There are two points to note.

(1) When importing the recorded script to a newly created Project, you need to import the Java JUnit package.

(2) unable to connect to host 127.0.0.1 on port7055 after
45000 MS, the specific error code is as follows

You only need to update the import to the latest selenium package in the Java project. This error occurs when I used 2.25.0, and then download the latest 2.28 on the official website.

How are you doing? It's easy. Come and try it.
