Test exim from CLI without "mail" command

If you don't have "mail" on the CLI for whatever, weird (Redhat-based) reasons, circumvent like so:

1. /path/to/exim -v 'user@domain'
2. type a multi-line message here ending with blank line
3. hit ^D to end message and send
4. you should be returned to shell

Selenium test on CLI in 5 minutes using Java

This took me two weeks to nail down looking at it here and there.

1. mkdir stests
2. cd stests
3. wget http://selenium.googlecode.com/files/selenium-java-2.33.0.zip
4. unzip selenium-java-2.33.0.zip
5. mkdir jars
6. find selenium-2.33.0 -type f -name '*jar' -exec mv -v {} jars \;
7. rm -rfv selenium-*
8. mkdir src
9. vi src/Test.java
1. use below code
10. mkdir out
11. javac -d out -cp 'jars/*' src/MyTest.java
1. ignore "Notes" output
12. cd out
13. rm -rfv org
14. java -cp '../jars/*:.' MyTest

import org.openqa.selenium.By;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.WebElement;

import org.openqa.selenium.firefox.FirefoxDriver;

import org.openqa.selenium.support.ui.ExpectedCondition;

import org.openqa.selenium.support.ui.WebDriverWait;

public class MyTest  {

    public static void main(String[] args) {

        WebDriver driver = new FirefoxDriver();

        driver.get("http://www.google.com");

        WebElement element = driver.findElement(By.name("q"));

        element.sendKeys("Cheese!");

        element.submit();

        System.out.println("Page title is: " + driver.getTitle());

        (new WebDriverWait(driver, 10)).until(new ExpectedCondition<Boolean>() {

            public Boolean apply(WebDriver d) {

                return d.getTitle().toLowerCase().startsWith("cheese!");

            }

        });

        System.out.println("Page title is: " + driver.getTitle());

        driver.quit();

    }

}
