Question

I wanna run selenium tests from TeamCity using Maven at Linux server without display.

While running Selenium tests I’m getting the following error in TeamCity:

Failed to execute goal org.codehaus.mojo:selenium-maven-plugin:2.3:xvfb (xvfb) on project my-project:
It appears that the configured display is already in use: :1

I installed x11-fonts*, xvfb, firefox, extracted DISPLAY=localhost:1, started xvfb

In pom.xml I added the following plugin:

                <plugin>
                    <groupId>org.codehaus.mojo</groupId>
                    <artifactId>selenium-maven-plugin</artifactId>
                    <version>2.3</version>
                    <executions>
                        <execution>
                            <id>xvfb</id>
                            <phase>pre-integration-test</phase>
                            <goals>
                                <goal>xvfb</goal>
                            </goals>
                            <configuration>
                                <display>:1</display>
                            </configuration>
                        </execution>

                        <execution>
                            <id>selenium</id>
                            <phase>pre-integration-test</phase>
                            <goals>
                                <goal>start-server</goal>
                            </goals>
                            <configuration>
                                <background>true</background>
                            </configuration>
                        </execution>
                    </executions>
                </plugin>

Do you have any ideas how to fix this problem?

UPD: xvfb is running using commmand

Xvfb :1 -screen 0 1920x1200x24 > /dev/null 2>&1 &

UPD: Before I’ve tried not to run xvfb before running tests, but was getting:

Execution xvfb of goal org.codehaus.mojo:selenium-maven-plugin:2.3:xvfb failed: Execute failed: java.io.IOException: Cannot run program "xauth": java.io.IOException: error=2, No such file or directory

Answer 1

I removed plugin declaration from pom.xml (as far as got to know that it’s for previous version of Selenium), installed xauth (not sure that was necessary) and everything began to work.
