Introduction

This project is to create a executable JAR file of the SaucelabsRunner class. Typically, this executable is run by a Jenkins job in which the Saucelabs Support plugin has been enabled.

Once Saucelabs is enabled in Jenkins and the desired Browser Type, Browser Version, and Platform (operating systems) have been selected, the environment variable SAUCE_ONDEMAND_BROWSERS is automatically set for the duration of the job.

When this JAR is executed, the SAUCE_ONDEMAND_BROWSERS environment variable is dynamically read and a PERL script is generated named parallel-exec.pl in the root of your Jenkins job which executed this runner.

The resulting PERL script is then able to concurrently run Maven instances of automated tests against any browser/version/platform version(s) selected in the Saucelabs Jenkins plugin. When the PERL script is executed the test results are output to the target/failsafe-reports-X (X = index of the number of browser/version/platform version(s) combinations you ran against.

This tool assumes you are using the core-microservice

Questions and issues

The github issue tracker is only for bug reports and feature requests. Anything else, such as questions for help in using the library, should be emailed to our team.

Prerequisites

Maven 3.x
Java 1.8

Maven Dependency

<dependency>
    <groupId>com.pacificwebconsulting.runner</groupId>
    <artifactId>runner-microservice</artifactId>
    <version>1.0.x</version>
</dependency>

Simplified Order of Operations

Compile Saucelabs Runner via Jenkins Job
Execute Saucelabs Runner JAR with SAUCE_ONDEMAND_BROWSERS environment variable set
Generate PERL script named 'parallel-exec.pl'
Run PERL script
PERL script runs asynchronous Maven jobs
Run tests via Maven
Gather test results with TestNG Jenkins plugin

Mandatory Variable Attributes

The following 2 fields must be defined by your Jenkins job and passed to PERL script in this order:

Maven Profile (example: regression)
Test Environment (example: pad-dev)

The following configuration must be included in your Profile in the POM.xml ${project.build.directory}/${test.results.dir}

<profile>
    <id>regression</id>
    <activation>
        <activeByDefault>false</activeByDefault>
    </activation>
    <build>
        <plugins>

            </plugin>
        </plugins>
    </build>

Execute PERL Runner

The following sample is how to execute this runner JAR to produce the resulting .pl PERL file from Jenkins. Execution from Jenkins is suggested becaause the Saucelabs plugin automatically sets the SAUCE_ONDEMAND_BROWSERS environment variable which is mandatory.

Jenkins Execution

Preconditions of this output are:

Jenkins & Saucelabs Plugin setting SAUCE_ONDEMAND_BROWSERS environment variable
Arg[0] MANDATORY Test Profile variable args sent on command line during execution
Arg[1] MANDATORY Test Environment variable args sent on command line during execution
Arg[2] OPTIONAL Browser Resolution variable args sent on command line during execution
Arg[3] OPTIONAL File Path to resulting PERL file variable args sent on command line during execution
Arg[4] OPTIONAL File Name to resulting PERL file variable args sent on command line during execution

java -cp "C:\Program Files (x86)\Jenkins\workspace\runner-microservice\target\runner-microservice-1.0.0-SNAPSHOT.jar" com.pwc.runner.SaucelabsRunner %Test_Profile% %Test_Environment%

PERL Output Sample

#! perl -slw
use strict;
use Thread qw(yield async);
system("mvn clean install");
my $t0 = async{
`mvn install -Pacceptance -Dtest.env=pad-dev -Dbrowser="chrome" -Dplatform="Windows 10" -Dbrowser.version=45 -Dtest.results.dir=failsafe-reports-0`
};
my $t1 = async{
`mvn install -Pacceptance -Dtest.env=pad-dev -Dbrowser="firefox" -Dplatform="Windows 7" -Dbrowser.version=44 -Dtest.results.dir=failsafe-reports-1`
};
my $output0 = $t0->join;
my $output1 = $t1->join;
print for $output0;
print for $output1;

Test Results

All test results are stored in multiple 'target/failsafe-reports-X' directories. In Jenkins, your Publish TestNG Results configuration settings must be modified with a wildcard since you will have multiple result XML files. This wildcard will be sure to combine all test results into a single TestNG test report.

IMPORTANT: Don't forget to add the configuration to your Maven profile to ensure the TestNG results are correctly reported

For example: **/testng-results.xml
