Selenium (chromedriver) in MAC - selenium

Question

I have the following problem/question:
I was with notebook automation. Now I bought an ultrabook MAC.
I did all the project import with automation, all right. However, when I run it, I get the following error:
java.lang.IllegalStateException: The driver executable does not exist: /Users/estevaomarcos/Documents/Projetos/DBServer/\Users\chromedriver
In my code is the following:
System.setProperty("webdriver.chrome.driver", "\\Users\\chromedriver");
WebDriver browser = new ChromeDriver(); .....

Answer 1

Set Driver Path: To avoid manual checking for the operating system we can get the file separator symbol from the system property using the file.separator key.
System.setProperty("webdriver.chrome.driver", "Users" + System.getProperty("file.separator") + "chromedriver");
WebDriver browser = new ChromeDriver();
browser.get("test.com");
Setting driver path based on which Operating System(OS) we are running on.
String os = System.getProperty("os.name").toLowerCase();
WebDriver driver = new ChromeDriver();
if(os.contains("mac")) {
System.setProperty("webdriver.chrome.driver", System.getProperty("usr.home") + System.getProperty("file.separator") + "chromedriver");
}else {
System.setProperty("webdriver.chrome.driver", System.getProperty("usr.home") + System.getProperty("file.separator") + "chromedriver.exe");
}

Answer 2

In a code based on operating system you should initialise new ChromeDriver after System.setProperty setup only.
user.home is correct option - NOT "usr"
Finally it works(java) great when looks like this:
String os = System.getProperty("os.name").toLowerCase();
if (os.contains("mac")) {
System.setProperty("webdriver.chrome.driver", System.getProperty("user.home") + System.getProperty("file.separator") + "chromedriver");
} else {
System.setProperty("webdriver.chrome.driver", System.getProperty("user.home") + System.getProperty("file.separator") + "chromedriver.exe");
}
WebDriver driver = new ChromeDriver();
