Webtests Reloaded - Webtest with Selenium, TestNG, Groovy and Maven

  1. 1. Thorsten Kamann Software-Architekt, Coach 25.05.2009
  2. 2. Webtest? Tools Setup & Run
  3. 3. Pitfalls Automatic Tests
  4. 4. Only manual Tests Click-Through Testing Different Browser? Only new/changed pages will be tested
  5. 5. Execute Test „anywhere and anytime“ Repeatable Tests Avoid the factor „Forgotten“ Old Feature are always tested Non-breakable Features
  6. 6. 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
  7. 7. Dynamic language for the Java-Platform Seamless Integration with jUnit and TestNG Powerful Syntax Easy Learning Toolsupport (Eclipse, Maven, Ant, …)
  8. 8. Testframework for Integrationstesting Annotation-based Configuration Parameterized Tests Datasource-Support for creation of testdata Toolsupport (Eclipse, Maven, Ant, …)
  9. 9. Buildtool Supports automatically testing Integration of Testframeworks Deklarative Toolsupport(Eclipse, Netbeans, IntelliJ, Konsole)
  10. 10. Architecture Usecases Projectsetup Execution of Tests Extensions
  11. 11. Tomcat petclinic.war HSQL DB Selenium
  12. 12. Run Tests Start Selenium Deploy Webapp Start Tomcat Compile
  13. 13. Usecase-driven Tests Definition of every User-Action Definition of Inputdata Definition of Return Values Recording with Selenium-IDE
  14. 14. m2Eclipse GroovyIDE TestNG
  15. 15. Java-Project Maven DM Groovy
  16. 16. DM: Groovy DM: TestNG
  17. 17. Groovy <dependency> <groupId>org.codehaus.groovy</groupId> <artifactId>groovy-all</artifactId> <version>1.5.6</version> </dependency> <dependency> <groupId>org.testng</groupId> <artifactId>testng</artifactId> <version>5.5</version> <classifier>jdk15</classifier> <optional>true</optional> <scope>test</scope> </dependency> TestNG with JDK5 Annotation-Support
  18. 18. testsuite.xml Grouping of Tests • Packages • Groups • Include/Excludes Definition of Parameter
  19. 19. Parameter <suite name=„webtest-reloadedquot;> <test name=„firefox-testsquot; annotations=quot;JDKquot;> <parameter name=quot;browserquot; value=quot;firefoxquot;/> <groups> <run> <include name=quot;it-testquot;></include> </run> </groups> Groups <packages> <package name=quot;selenium.groovy.testngquot;/> </packages> </test> </suite> Packages
  20. 20. Export of Testcases PHP, C#, Java JavaScript for Export Language Any Target Language is supported
  21. 21. 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;; }
  22. 22. 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 { … } }
  23. 23. Maven Surefire-Plugin • Deactivate Lifecycle test • Activate Lifecycle integration-test • Integrate TestNG‘s testsuite.xml
  24. 24. Deactivate Lifecycle test <plugin> <artifactId>maven-surefire-plugin</artifactId> <configuration> <skip>true</skip> </configuration> Activate <executions> Lifecycle integration-test <execution> <phase>integration-test</phase> <configuration> <skip>false</skip> <suiteXmlFiles> <suiteXmlFile>src/test/config/it-suite.xm</suiteXmlFile> </suiteXmlFiles> </configuration> </execution> Integrate </executions> testsuite </plugin>
  25. 25. pre-integration-test Deploy Start Tomcat Webapp post-integration-test Undeploy Stop Tomcat Webapp
  26. 26. <<Sourcecode too long… please see the sample project>>
  27. 27. pre-integration-test Optional: start-server Prepare Firexox profile post-integration-test stop-server
  28. 28. Start Selenium-Server <plugin> <artifactId>selenium-maven-plugin</artifactId> <executions> <execution> <phase>pre-integration-test</phase> <goals> <goal>start-server</goal> </goals> <configuration> <background>true</background> <firefoxProfileTemplate> Prepared Firefox … Profile </firefoxProfileTemplate> </configuration> </execution> </executions> </plugin>
