This project demonstrates the usage of the Concordion Exception Translator Extension with Selenium WebDriver.

Example output is shown here.

Running the tests

The tests use Selenium's FirefoxDriver, so you'll need to have Firefox installed (or you could change the code to use a different driver).

The download includes support to run the tests with either Gradle or Maven.

Using Gradle

  1. Download and install Gradle (this has been tested with 2.1)
  2. From a command line opened at the location to which this package has been unzipped, run gradle clean test
  3. View the Concordion output under the subfolder build/reports/spec/org/concordion/ext/demo/selenium/

Using Maven

  1. Download and install maven (this has been tested with 3.0.3)
  2. From a command line opened at the location to which this package has been unzipped, run mvn test
  3. View the Concordion output under the subfolder target/concordion/org/concordion/ext/demo/selenium/

Running from your IDE

Import as a Gradle or as a Maven project. This may require additional plugins to be installed to support Gradle or Maven.

Under the src/test/java folder, find the ExceptionTranslatorDemo class in the org.concordion.ext.demo.selenium package and run as a JUnit test. The location of the Concordion output is shown on the standard output console.

What you should see

The test will open a Firefox browser at the Google home page.

JUnit output

The test should pass successfully, though the console output will show an exception with the message:

<-- Note: This test has been marked as EXPECTED_TO_FAIL

The test deliberately throws an exception in order to demonstrate the extension. It uses Concordion's @ExpectedToFail annotation to keep the JUnit passing (you'd normally only use this when you have a partially implemented feature).

Concordion output

The output folder should contain the following specification. (You can see an example of it here).


Shows the use of the ExceptionTranslatorExtension to remove debug information from the WebDriver exception output.

Potential Issues


If you are behind a HTTP proxy server, you may need to configure the proxy to allow access to www.google.com

The easiest way to do this may be to add the following lines to the Site() constructor:

    System.setProperty("http.proxyHost", "<proxy.host>");
    System.setProperty("http.proxyPort", "<proxy.port>");

replacing <proxy.host> with the host name of the proxy server, and <proxy.port> with the port number.

If your proxy requires authentication, you will also need to set the properties http.ProxyUser and http.proxyPassword.

Additional Gradle Files

dev.gradle is only needed if you want to run against snapshot or local builds of the concordion-screenshot-extension. publish.gradle is only needed if you want to publish the output to Github pages.

If copying the project for your own use, you probably won't want either of these files.
