Assert element color in Selenium IDE

IMHO the idea be the following:we simply need to get css property(color, in particulat) of element before click. and get css property(color ) of the element after click on it.

so it be like (I work on java and we will execute a piece of javascript using jsExecutor to implement getColor function. It will take css selector of the element. And get return its color):

public String jsGetColor(String css){        JavascriptExecutor js = (JavascriptExecutor) driver;        StringBuilder stringBuilder = new StringBuilder();        stringBuilder.append("var x=$(\'"+css+"\');");        stringBuilder.append("return x.css('color')");        //stringBuilder.append("return x.css('background-color')");        String res= (String) js.executeScript(stringBuilder.toString());        return res;    }String cssSelectorLink="a[class='mg-friend-12345 friend selected']";WebElement linkToClick = driver.findElemebt(By.cssSelector(cssSelectorLink));String colorBeforeClick = jsGetColor(cssSelectorLink);linkToClick.click();String colorAfterClick = jsGetColor(cssSelectorLink);Assert.assertFalse(colorBeforeClick.equals(colorAfterClick));

Hope it be helpful for you.

well I work in intelij IDEA. So setUp to write selenium tests e.g. be the following:

1) install maven

• Unzip the distribution archive, i.e. apache-maven-3.0.4-bin.zip tothe directory you wish to install Maven 3.0.4. These instructionsassume you chose C:\Program Files\Apache Software Foundation. Thesubdirectory apache-maven-3.0.4 will be created from the archive.
• Add the M2_HOME environment variable by opening up the systemproperties (WinKey + Pause), selecting the "Advanced" tab, and the"Environment Variables" button, then adding the M2_HOME variablein the user variables with the value C:\Program Files\ApacheSoftware Foundation\apache-maven-3.0.4. Be sure to omit anyquotation marks around the path even if it contains spaces. 
• In the same dialog, add the M2 environment variable in the uservariables with the value %M2_HOME%\bin.

2) install jdk3)

4) verify that all environment variables you've set properly5) run intelij IDEAselect Project structure to set up installed JDK6)press New.select jsdk. write path where we installed java, e.g C:\Program Files\Java\jdk1.6.0_297)create new project from scratch8) maven module9) 10) 11) add to POM appropriate dependencies:

   <dependency> <groupId>org.seleniumhq.selenium</groupId> <artifactId>selenium-java</artifactId> <version>2.24.1</version> </dependency> 

12) if still someting underline with red line , press alt+enter on it >> idea should automatically suggest autoimport.

13)test structure in the project

14)common structure of selenium test

import com.thoughtworks.selenium.SeleneseTestBase;import org.junit.After;import org.junit.Before;import org.junit.BeforeClass;import org.junit.Test;import org.openqa.selenium.By;import org.openqa.selenium.WebDriver;import org.openqa.selenium.WebElement;import org.openqa.selenium.firefox.FirefoxDriver;import java.util.concurrent.TimeUnit;public class HomePageTest extends SeleneseTestBase{    static WebDriver driver;    @Before    public void openFirefox(){        driver = new FirefoxDriver();        driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);    }    @Test    public void testHomePage(){        driver.get("https://www.google.by/");        WebElement search = driver.findElement(By.xpath("//*[@id=\"gbqfq\"]"));        search.sendKeys("laptop");        search.submit();    }    @After    public void closeFirefox(){        // driver.quit();    }}

15) also don't forget that you can export your created test in selenium IDE as JUNIT4- selenium and open them in IDEA
