Making System.setProperty platform independent in

Question

I am currently creating selenium automation using webdriver in Maven using Java. Now for initializing the browsers such as Chrome and IE I have to set the system property such as

System.setProperty("webdriver.chrome.driver", "F:\\somewhereintheworkingdir\\drivers\chromedriver.exe");

Now, my deliverable is in terms of JAR. I am using maven so this is currently under main>resources>drivers>chromedriver.exe

So after package it will be unders root>drivers>chromedriver.exe

So How to make the system property that it will run in both the cases?

I researched about some constants like java.class.path or java.file.seperator etc. but I am not sure how they will useful here in this case.

I hope someone can help me.

I would suggest having a look at this:

https://github.com/Ardesco/Selenium-Maven-Template

The relevant parts are the POM where it uses this plugin:

<properties>
    <standalone.binary.root.folder>${project.basedir}/selenium_standalone_binaries</standalone.binary.root.folder>
</properties>

<profiles>
    <profile>
        <id>selenium-tests</id>
        <build>
            <plugins>
                <plugin>
                    <groupId>com.lazerycode.selenium</groupId>
                    <artifactId>driver-binary-downloader-maven-plugin</artifactId>
                    <version>0.9.2</version>
                    <configuration>
                        <rootStandaloneServerDirectory>${standalone.binary.root.folder}</rootStandaloneServerDirectory>
                        <downloadedZipFileDirectory>${project.basedir}/selenium_standalone_zips</downloadedZipFileDirectory>
                        <customRepositoryMap>${project.basedir}/RepositoryMap.xml</customRepositoryMap>
                    </configuration>
                    <executions>
                        <execution>
                            <goals>
                                <goal>selenium</goal>
                            </goals>
                        </execution>
                    </executions>
                </plugin>
            </plugins>
        </build>
    </profile>
</profiles>

and in the base class where it pulls in the locations of the binaries:

private static ResourceBundle _prop = ResourceBundle.getBundle("dev");
//Load standalone executable if required
switch (browserType) {
    case CHROME:
        if (System.getProperties().getProperty("os.arch").toLowerCase().equals("x86_64") || System.getProperties().getProperty("os.arch").toLowerCase().equals("amd64")) {
            if (System.getProperties().getProperty("os.name").toLowerCase().contains("windows")) {
                System.setProperty("webdriver.chrome.driver", _prop.getString("binaryRootFolder") + "/windows/googlechrome/64bit/26/chromedriver.exe");
            } else if (System.getProperties().getProperty("os.name").toLowerCase().contains("mac")) {
                System.setProperty("webdriver.chrome.driver", _prop.getString("binaryRootFolder") + "/osx/googlechrome/64bit/26/chromedriver");
            } else if (System.getProperties().getProperty("os.name").toLowerCase().contains("linux")) {
                System.setProperty("webdriver.chrome.driver", _prop.getString("binaryRootFolder") + "/linux/googlechrome/64bit/26/chromedriver");
            }
        } else {
            if (System.getProperties().getProperty("os.name").toLowerCase().contains("windows")) {
                System.setProperty("webdriver.chrome.driver", _prop.getString("binaryRootFolder") + "/windows/googlechrome/32bit/26/chromedriver.exe");
            } else if (System.getProperties().getProperty("os.name").toLowerCase().contains("mac")) {
                System.setProperty("webdriver.chrome.driver", _prop.getString("binaryRootFolder") + "/osx/googlechrome/32bit/26/chromedriver");
            } else if (System.getProperties().getProperty("os.name").toLowerCase().contains("linux")) {
                System.setProperty("webdriver.chrome.driver", _prop.getString("binaryRootFolder") + "/linux/googlechrome/32bit/26/chromedriver");
            }
        }
        break;
    case IE:
        if (System.getProperties().getProperty("os.arch").toLowerCase().equals("x86_64") || System.getProperties().getProperty("os.arch").toLowerCase().equals("amd64")) {
            System.setProperty("webdriver.ie.driver", _prop.getString("binaryRootFolder") + "/windows/internetexplorer/64bit/2.29.0/IEDriverServer.exe");
        } else {
            System.setProperty("webdriver.ie.driver", _prop.getString("binaryRootFolder") + "/windows/internetexplorer/32bit/2.29.0/IEDriverServer.exe");
        }
        break;
}

You also need to have a properties file in src/main/resources (has to be in main, not test) that maven can update at build time to pass in properties set in the POM/overridden on the command line.

That file would look like this:

binaryRootFolder=${standalone.binary.root.folder}

The easiest thing to do would be clone the project linked to at the start of this answer and just run:

mvn verify -Pselenium-tests

That will show you everything working and give you a good base to start from.
