Jenkins HtmlUnit is obsolete

[Pavel Baranchikov]

Hello,

Jenkins has its own HtmlUnit module, that is downloaded throught Maven as dependency to jenkins test harness. But the module is rather old - as I understand it is of version 2.6 instead of 2.15 version of the original HtmlUnit.

This prevents me from testing my Html (with JavaScript)

Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 19.895 sec <<< FAILURE! - in hudson.plugins.git.ui.ChangeSetListTest
test1(hudson.plugins.git.ui.ChangeSetListTest)  Time elapsed: 17.864 sec  <<< ERROR!

The method querySelectorAll() support has been added since 2.9 according to http://htmlunit.sourceforge.net/changes-report.html

Is there a way to correctly replace HtmlUnit to the new version locally in my plugin's project?
Are there plans to renew Jenkins-shipped version of HtmlUnit?

Hello Pavel,

as Jenkins uses Maven, you should be able to override the version by
standard Maven means:
* Exclude the htmlunit stuff from the test-harness
* Then add the versions you want.

<dependencies>
<dependency>
<groupId>org.jenkins-ci.main</groupId>
<artifactId>jenkins-test-harness</artifactId>
<version>${project.parent.version}</version>
<scope>test</scope>
<exclusions>
<exclusion>
<groupId>org.jenkins-ci</groupId>
<artifactId>htmlunit</artifactId>
</exclusion>
<exclusion>
<groupId>org.jvnet.hudson</groupId>
<artifactId>htmlunit-core-js</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>net.sourceforge.htmlunit</groupId>
<artifactId>htmlunit</artifactId>
<version>2.15</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>net.sourceforge.htmlunit</groupId>
<artifactId>htmlunit-core-js</artifactId>
<version>2.15</version>
<scope>test</scope>
</dependency>
</dependencies>



Regards Mirko

Hello, Mirko

It seems to be impossible to just replace HtmlUnit with a new version,
because
org.jvnet.hudson.test.HudsonTestCase.WebClient.WebClient(HudsonTestCase) uses
field BrowserVersion.FIREFOX_2, which is no longer used in HtmlUnit.


Tests in error:
FailedTest.org.jvnet.hudson.test.JellyTestSuiteBuilder$JellyTestSuite »
NoSuchField
PreBuildMergeOptionsTest.exporting:48 » NoSuchField FIREFOX_2
GitSCMTest>HudsonTestCase.runBare:296->HudsonTestCase.runTest:440-
>testConfigRoundtripURLPreserved:1229->HudsonTestCase.configRoundtrip:888-
>HudsonTestCase.createWebClient:1617 » NoSuchField
GitSCMTest>HudsonTestCase.runBare:296->HudsonTestCase.runTest:440-
>testConfigRoundtrip:1240->HudsonTestCase.configRoundtrip:888-
>HudsonTestCase.createWebClient:1617 » NoSuchField


So, new HtmlUnit substitution should make some problems, and, of course,
should cause every existing test to fail.

I wonder, whether Jenkins-patched HtmlUnit is still needed for Jenkins. Project https://github.com/jenkinsci/htmlunit/branches/all has no commits and changes for last 3 years.
