Building and testing software can be a time and resource consuming task. Cloud computing / on demand services like Amazon EC2 allow a cost-effective way to scale applications, and applied to building and testing software can reduce the time needed to find and correct problems, meaning a reduction also in time and costs. Properly configuring your build tools (Maven, Ant,...), continuous integration servers (Continuum, Cruise Control,...), and testing tools (TestNG, Selenium,...) can allow you to run all the build/testing process in a cloud environment, simulating high load environments, distributing long running tests to reduce their execution time, using different environments for client or server applications,... and in the case of on-demand services like Amazon EC2, pay only for the time you use it. In this presentation we will introduce a development process and architecture using popular open source tools for the build and test process such as Apache Maven or Ant for building, Apache Continuum as continuous integration server, TestNG and Selenium for testing, and how to configure them to achieve the best results and performance in several typical use cases (long running testing processes, different client platforms,...) by using he Amazon Elastic Computing Cloud EC2, and therefore reducing time and costs compared to other solutions.

Enterprise Build And Test In The Cloud

  1. Enterprise Build & Test in the Cloud Carlos Sanchez March 27, 2009
  2. About me During the day Sr. Solutions Architect at G2iX At night Member of Apache Maven PMC, Continuum, Archiva Eclipse IAM co-lead
  3. Index The tools Maven Integration Tests Maven & Selenium Adding Continuum to the Mix Testing in Different Environments And Now in the Cloud
  4. The tools
  5. Build Apache Maven
  6. Maven Build tool and more Dependency management Execution of unit /integration tests Start/stop application server Automatic application deployment
  7. How many?
  8. Test cases TestNG
  9. TestNG Unit/integration tests parameterized tests parallel testing
  10. How many?
  11. Integration tests Selenium
  12. Selenium UI and Integration testing Tests run in the browser support for multiple browsers Tests can be recorded no need for developers writing tests Selenium IDE Firefox plugin
  13. How many?
  14. Continuous Integration Apache Continuum
  15. Apache Continuum Tight integration with Apache Maven dependency handling Trigger builds when integration tests change when the webapp changes when the webapp dependencies change
  16. How many?

  30. ... as Java
  31. test cases ...using Selenium API public void setUp() throws Exception { setUp(quot;http://localhost:18880/quot;, quot;*chromequot;); } public void testNew() throws Exception { selenium.open(quot;/mainMenu.htmlquot;); selenium.click(quot;link=Administrationquot;); selenium.waitForPageToLoad(quot;30000quot;); selenium.type(quot;j_passwordquot;, quot;adminquot;); selenium.click(quot;rememberMequot;); selenium.click(quot;//input[@name='login']quot;); selenium.waitForPageToLoad(quot;30000quot;); selenium.click(quot;link=Edit Profilequot;); selenium.waitForPageToLoad(quot;30000quot;); selenium.click(quot;link=Main Menuquot;); selenium.waitForPageToLoad(quot;30000quot;); selenium.click(quot;link=Edit Profilequot;); selenium.waitForPageToLoad(quot;30000quot;); selenium.click(quot;document.forms[0].elements[24]quot;); selenium.waitForPageToLoad(quot;30000quot;); }
  32. breakpoint we have Selenium tests in Maven IT project
  33. Maven & Selenium
  34. Selenium Architecture Selenium server
  35. Maven & Selenium Start Selenium server locally Run integration tests Stop selenium server
  36. Selenium Maven plugin http://mojo.codehaus.org/ selenium-maven-plugin selenium:start-server selenium:stop-server
  37. configuration <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>selenium-maven-plugin</artifactId> <version>1.0-rc-1</version> <executions> <execution> <id>start-selenium</id> <phase>pre-integration-test</phase> <goals> <goal>start-server</goal> </goals> </execution> </executions> <configuration> <background>${selenium.background}</background> </configuration> </plugin>
