=== Testing a Jetty Release

To test a Jetty release, complete the following steps for each release you want to test:

1.  Download the staged release:
+
[source, screen, subs="{sub-order}"]
....

 wget https://oss.sonatype.org/content/repositories/jetty-[reponumber]/org/eclipse/jetty/jetty-distribution/[jetty-version]/jetty-distribution-9.[jetty-minor-version].tar.gz

      
....
2.  Extract to a directory of your choice.
3.  Start jetty:
+
[source, screen, subs="{sub-order}"]
....

 cd [installdir] ; java -jar start.jar
 
      
....
4.  If there are no exceptions, proceed. Otherwise, investigate.
5.  Open http://localhost:8080/ in a browser. In the examples section click "Test Jetty Webapp". You should see the `test.war` webapp.
6.  Go through ALL the tests and verify that everything works as expected.
7.  In the examples section click "JAAS Test" and verify that everything works as expected.
8.  In the examples section click "JNDI Test" and verify that everything works as expected.
9.  In the examples section click "Servlet 3.1 Test" and verify that everything works as expected.
10. Verify that hot deployment works.
+
[source, screen, subs="{sub-order}"]
....

 cd [installdir] ;
 touch [pathToJettyDistribution]/webapps.demo/test.xml
 
      
....
11. Verify that `test.war` gets redeployed in `STDOUT`.
12. Verify that the spdy example webapp and spdy-proxy do work
+
[source, screen, subs="{sub-order}"]
....

 cd jetty_src/jetty-spdy/spdy-example-webapp
 mvn jetty:run-forked
 
      
....
13. Browse to https://localhost:8443 and verify that all looks ok
14. Stop the server with CTRL+C and restart it in proxy mode:
+
[source, screen, subs="{sub-order}"]
....

 mvn -Pproxy jetty:run-forked
 
      
....
15. Browse to http://localhost:8080 and https://localhost:8443 and verify that all looks ok

==== Testing CometD

1.  Clone CometD.
+
[source, screen, subs="{sub-order}"]
....

 clone git://github.com/cometd/cometd.git
 git clone git://github.com/cometd/cometd.git
 
        
....
2.  Edit `pom.xml` and update `jetty-version.`
+
....

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <jetty-version>7.6.2.v20120308</jetty-version>
        <jetty-plugin-version>${jetty-version}</jetty-plugin-version>
        <slf4j.version>1.6.4</slf4j.version>
        <spring-version>3.1.0.RELEASE</spring-version>
    </properties>
    <repositories>
    <repository>
      <id>Jetty Staging</id>
      <url>https://oss.sonatype.org/content/repositories/jetty-988/</url>
    </repository>
  </repositories>
 
        
....
3.  Build Cometd:
+
[source, screen, subs="{sub-order}"]
....

 mvn clean install
  
        
....
4.  Be patient.
5.  Run the loadtest as it is described here: http://cometd.org/documentation/2.x/howtos/loadtesting.
Keep the default values, but make sure that you raise the clients setting to 1000.
Run the loadtest until ''JIT compilation time'' is close to a value of zero (about 10k calls).
6.  Make sure that the performance results are reasonably fast.

8.  Start jetty and make sure there are no exceptions.
+
[source, screen, subs="{sub-order}"]
....

 cd [pathToJetty] && java -jar start.jar
 
        
....
9.  Go through all pages of the demo and test them:
+
....

 http://localhost:8080/cometd-demo-2.4.1-SNAPSHOT/
