Maven, Selenium and a hint of Groovy

Getting selenium running on maven using selenium-rc and tests written in groovy is a piece of cake, well at least when someone else has written the tutorial already: Grails, Selenium, Maven and integration testing

The only thing I found lacking for my use case was nice html reports. Those can can be added using the maven-surefire-report-plugin.

Add this to mavens pom.xml:

<project>
...

<reporting>
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-surefire-report-plugin</artifactId>
      <version>2.4.2</version>
    </plugin>
  </plugins>
</reporting>

...
</project>

Everything works now right?

Well yeah, as long as you aren't on a Mac upgraded to Snow Leopard. Basically there is a problem with Firefox and Snow Leopard which makes Selenium crash. After some googling I found this post, mentioning among other things a fix to our problem (step 4).

This solved the problem for me (copy into the terminal):

# Make a backup of the old file
mv /Applications/Firefox.app/Contents/MacOS/libsqlite3.dylib \\
/Applications/Firefox.app/Contents/MacOS/libsqlite3.dylib.orig

# Copy in the working file
cp /usr/lib/libsqlite3.dylib \\
/Applications/Firefox.app/Contents/MacOS/libsqlite3.dylib

Show me the code!

All you really need is maven and the pom. To make it all as simple as possible I've put a complete demo up on github, modify it to suit your needs. I used groovy to write the selenium tests but java should work as well.

Whats your thoughts on the matter? Comments below and trackbacks here

Hello, nice post. I have a question, is there a way to do code coverage on groovy code ... ?

Yes, you can use Cobertura (http://cobertura.sourceforge.net/) to do coverage on Groovy code. If you're using Grails, you can even use the Code-Coverage plugin (http://grails.org/plugin/code-coverage) to do it

Thanks. As Mike said you can use cobertura to generate a cove-coverage report for your Groovy based tests. If you're using maven it's as easy as adding the following to your poms build plugins. <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>cobertura-maven-plugin</artifactId> </plugin>

Sorry about the bad formatting, we really need to look into how comments are handled on the blog. You can read more about using the Cobertura maven-plugin here: http://mojo.codehaus.org/cobertura-maven-plugin/

Thanks, now I have basic code coverage support. But have a problem if I want to see lines which are (not)covered, after click on source file link gives me a message "Unable to locate xxx.groovy. Have you specified the source directory?".

I went back to check my old code and couldnt find any working examples of using maven with cobertura for groovy-code, I'll have to get back to you on that one.

I wrote a simple howto for Snow Leopard and selenium using firefox 3.5. You can find it here http://www.god-object.com/2009/10/16/user-interface-testing-on-mac-os-10-6-snow-leopard/
