In our WAR packaging scheme, we package SCA artifacts with Tuscany runtime jars in a WAR so that it can be deployed to a web container such as Tomcat, Jetty or Geronimo. In release 1.1, we already have 5-6 samples as web applications.
1) Most of the validation of web applications is done manully before a release. This is time-consuming and error prone.
2) Our integration tests are not performed in the WAR packaging scheme. Trying samples is a smoke test. If we can run the itests in a web application, we'll get much more coverage.
To address the above issues, I propose that we add the following capabilities:
1) Provide an option to wrap itests into web applications with little effort to convert the test cases
2) Automate the steps to start/stop a web container and deploy web applications to the container
3) Automate the testing of our JUnit-based test cases in the web application
I did some prototyping and here is what I have achieved so far:
1) Add some code to "org.apache.tuscany.sca.host.webapp.TuscanyServletFilter" (tuscany-host-webapp) to intercept the HTTP requests to a special path "/junit". The control is then delegated to a new class WebTestRunner that knows how to find and run the JUNIT test cases and produce the results of the test (for example, number of runs, failures and errors, similar with what maven surefire plugin does). The report is sent back to the web client.
With this, we can run the plain JUNIT test cases in the web application by connecting to a URL like http://localhost:8080/<app-name>/junit.
2) Adjust the sample-calculator-webapp to validate the idea
3) Run the maven build as ususal, produce a WAR, deploy to Tomcat, browse to http://localhost:8080/sample-calculator-webapp/junit, and see the test results in the browser. To run a selected list of test cases, http://localhost:8080/sample-calculator-webapp/junit?test1,test2.
This seems to be non-invasive as we already configure the servlet filter for web applications. The regular URLs to JSPs or web services stay the same. We don't have to change the test case code too much.
I also went a bit further:
1) Developed a maven plugin to trigger the web-based junit tests and analyze the results
2) Configure the pom.xml with cargo plugin to start an embedded Jetty server, deploy the WAR, trigger the web-based junit tests, and stop the server.
Now I have a complete automation. To avoid repeating the pom configuration for each itest, we can add a profile in the parent pom to support this scheme.
