The most difficult part to test is the WebUI. This part of an application only manually tested. With Selenium you are able to test WebUIs on a simple way. In this article we shows you how to automating the test process.

2. Webtest? Tools Setup & Run

3. Pitfalls
Automatic Tests

4. Only manual Tests
Click-Through Testing
Different Browser?
Only new/changed pages
will be tested

5. Execute Test „anywhere and
anytime“
Repeatable Tests
Avoid the factor „Forgotten“
Old Feature are always tested
Non-breakable Features

7. Usable for direct testing of Web-UIs
Selenium RemoteControl starts the
commands direct in the browser
No Java-Implementation of a
Browser-Engine
Create tests with the Selenium-IDE
Export the Testskripts with
JavaScript in any target language

9. Dynamic language for the
Java-Platform
Seamless Integration with
jUnit and TestNG
Powerful Syntax
Easy Learning
Toolsupport (Eclipse, Maven,
Ant, …)

10. Testframework for
Integrationstesting
Annotation-based
Configuration
Parameterized Tests
Datasource-Support for
creation of testdata
Toolsupport (Eclipse, Maven,
Ant, …)

11. Buildtool
Supports automatically
testing
Integration of Testframeworks
Deklarative
Toolsupport(Eclipse,
Netbeans, IntelliJ, Konsole)

12. Architecture
Usecases
Projectsetup
Execution of Tests
Extensions

13. Tomcat
petclinic.war
HSQL
DB
Selenium

15. Run Tests
Start
Selenium
Deploy
Webapp
Start
Tomcat
Compile

16. Usecase-driven Tests
Definition of every User-Action
Definition of Inputdata
Definition of Return Values
Recording with Selenium-IDE

24. testsuite.xml
Grouping of Tests
• Packages
• Groups
• Include/Excludes
Definition of Parameter

25. Parameter
<suite name=„webtest-reloadedquot;>
<test name=„firefox-testsquot; annotations=quot;JDKquot;>
<parameter name=quot;browserquot; value=quot;firefoxquot;/>
<groups>

26. Export of Testcases
PHP, C#, Java
JavaScript for Export
Language
Any Target Language is
supported

28. function assertTrue(expression) {
return
quot;AssertJUnit.assertTrue(quot; + expression.toString() + quot;)quot;;
}
function assignToVariable(type, variable, expression) {
return type + quot; quot; + variable + (expression)? quot; = quot;
+ expression.toString(): quot;quot;;
}

29. public class NewTest {
Selenium selenium
String baseUrl = quot;ENTER_BASEURL_HEREquot;
@BeforeClass(groups=[quot;it-testquot;])
public void beforeClass(){…}
@BeforeMethod(groups=[quot;it-testquot;])
public void startSelenium(){…}
@AfterMethod(groups=[quot;it-testquot;])
public void stopSelenium(){…}
@Test(groups=[quot;it-testquot;])
public void executeIntegrationTest {
…
}
}

30. Maven Surefire-Plugin
• Deactivate Lifecycle test
• Activate Lifecycle integration-test
• Integrate TestNG‘s testsuite.xml

31. Deactivate
Lifecycle test
<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<skip>true</skip>
</configuration> Activate
<executions> Lifecycle integration-test
<execution>
<phase>integration-test</phase>

<suiteXmlFiles>
<suiteXmlFile>src/test/config/it-suite.xm</suiteXmlFile>
</suiteXmlFiles>
</configuration>
</execution> Integrate
</executions> testsuite
</plugin>

32. pre-integration-test
Deploy
Start Tomcat Webapp
post-integration-test
Undeploy Stop Tomcat

33. <<Sourcecode too long…
please see the sample project>>

34. pre-integration-test
Optional:
start-server Prepare
Firexox profile
post-integration-test
stop-server

35. Start
