Thucydides Release 0.9.229

There have been many releases since the last release notes were published, so this entry will summarize some of the highlights that are included in release 0.9.229 (though many came out in releases previous to that). Some of the highlights include:

  • Added support for Selenium 2.39.0
  • Testing AngularJS is made easier with support for the ng-model attribute in the Thucydides @FindBy annotation. Suppose you have this AngularJS input field:
<input ng-model="angularField" value="Model value" />

You can now find this directly using the Thucydides @FindBy:

import net.thucydides.core.annotations.findby.FindBy
 @FindBy(ngModel = "angularField")
 public WebElementFacade ngModelField;
  • Support for nested page objects – you can have page object fields inside other page objects. This makes it easier to write page objects for smaller reusable sections of the screen.
  • You don’t need to override the constructors for ScenarioSteps and PageObjects any more
  • You can provide your own webdriver instance using the ‘webdriver.provided.type’. Just implement the DriverSource interface. For example, you could implement a class like this:
package com.acme
public class MyFunkyDriverSourceImpl implements DriverSource {
    public WebDriver newDriver() {
       return new FunkyWebDriver();

Then just run the tests with the following properties (e.g. in the file or on the command line):

webdriver.driver = provided
 webdriver.provided.type = funky
 webdriver.provided.funky = com.acme.MyFunkyDriverSourceImpl
  • Lots of improvements to the reports, including:
    • Reports now have the option to hide the pie chart on the aggregate pages
    • Test reports now display the date and time of the report generation on each page.
    • You can use the ‘show.related.tags’ system property to display (default) or hide related tag statistics on the dashboard
    • Support for reporting on releases/versions by integrating with JIRA (there will be a full article on this feature shortly)
    • Support for integration with 3rd party test management software such as the JIRA Zephyr plugin to report on manual as well as automated tests
  • Many bug fixes

If you are still on an older version, update your dependencies today!


Thucydides Release 0.9.94 – More improvements to reports and some bug fixes

We released version 0.9.94 of Thucydides over the weekend.

Improved reports home page

Reports home page now shows two pie charts, one with the overall tests count and another with the test count weighted by number of steps.

The first pie chart gives an overall status of the tests as it shows how many tests have passed, failed or are still pending. The second pie-chart gives the test status weighted by number of steps which could be used to deduce the nature/criticality of test failures.

There are also some minor improvements to the requirements reporting page.

Updated Selenium version to 2.29.0

Selenium version has been updated to 2.29.0 (Selenium Release notes)

Minor enhancements and bug Fixes

  • #Thucydides-122: Added thucydides.verbose.steps property, that provides more detailed logging of WebElementFacade steps.
  • #Thucydides-125: Fixed a bug that caused reports to fail for parameterized tests with new line characters in the test data.
  • #Thucydides-130: Fixed a bug due to which PageObject.upload was not working for files on classpath.

Faster Web Tests with Parallel Batches in Thucydides

Web tests are as a rule much slower than other types of tests, but they can be sped up significantly by running them in parallel. However, this is often harder to implement than it sounds. The latest version of Thucydides (version 0.6.0) comes with support for running parallel test batches, making this task much easier.

Web tests make good candidates for concurrent testing, in theory at least, but the implementation can be tricky. For example, although it is easy enough to configure both JUnit and easyb to run tests in parallel, running several webdriver instances of Firefox in parallel on the same display, for example, tends to become unreliable.

The natural solution in this case is to split the web tests into smaller batches, and to run each batch on a different machine and/or on a different virtual display. When each batch has finished, the results can be retrieved and aggregated into the final test reports.

However splitting tests into batches by hand tends to be tedious and unreliable – it is easy to forget to add a new test to a batch, for example, or have unevenly-distributed batches.

The latest version of Thucydides lets you do this automatically, by splitting your test cases evenly into batches of a given size. In practice, you run a build job for each batch. You need to specify two parameters when you run each build: the total number of batches being run (thucydides.batch.count), and the number of the batch being run in this build (thucydides.batch.number).

For example, the following will divide the test cases into 3 batches (“thucydides.batch.count”), and only run the first test in each batch (thucydides.batch.number):

mvn verify -Dthucydides.batch.count=3 -Dthucydides.batch.number=1

This will only work with the JUnit integration. However this feature is also now supported in easyb (as of easyb version 1.5), though using different parameters. When using the Thucydides easyb integration, you also need to provide the equivalent options for easyb:

mvn verify -Deasyb.batch.count=3 -Deasyb.batch.number=1

If you have both easyb and JUnit Thucydides tests, you will need to specify both options.

Parallel web tests on Jenkins

This approach is easy to set up on Jenkins using a multi-configuration build. In the following screenshot, we are running a multi-configuration build to run web tests across three batches. We use a single user-defined parameter (BATCH_NUMBER) to define the batch being run, passing this parameter into the Maven build job properties we discussed above.

The most robust way to aggregate the build results from the different batches is to set up a second build job that runs after the test executions, and retrieves the build results from the batch jobs. You can use the Jenkins Copy Artifacts plugin to do this. First, ensure that the multi-configuration build archives the Thucydides reports, as shown here:

This build will then trigger another, freestyle build job. This job needs to copy the Thucydides report artifacts from the matrix build jobs into the current workspace, and then run the mvn thucydides:aggregate command to generate the Thucydides aggregate reports. The matrix build job reports need to be copied one-by-one for each batch, as the current version of the Copy Artifacts plugin does not support copying from multiple projects in the same action.

Then make sure you publish the generated HTML reports (which will be in the target/site/thucydides directory) for easy access to the test results.

This simple example shows a parallel test running 3 batches – this brought the test execution time from 9 minutes to slightly over 1 minute. Results will vary, of course, but a typical real-world set of web tests would have a larger number of batches.


Using Selenium 2.6 ExpectedConditions with Thucydides

Selenium 2.6 provides a new API that allows more fluent wait conditions, such as waiting for several fields to be visible or enabled. This has been integrated into the Thucydides PageObject class with a helper method to make it a bit easier to use. Read more »
