Learn Selenium scripting guidelines using real time examples,
while implementing selenium Test scripts, Preparing Selenium framework using
Java or any other language it is very important to follow some important
selenium guidelines for scripting, follow below simple and important guidelines
to prepare robust Selenium frameworks.
Selenium WebDriver Scripting Guidelines
1. Export Project as a JAR file
After creating Selenium Test
Scripts for web application projects, just convert project into JAR file and it
is easy to run without opening Eclipse IDE or any other tools, which you are using.
Why JAR file means, in order to run your Selenium scripts across the different
platforms such as windows, mac OS etc.
You can run Selenium project
JAR file in command prompt as below
1.
Go to
Project folder path where JAR file is exported
2.
Now
Enter java -jar runnablejar.jar
3.
Hit
Enter
It'll start executing your Test
Scripts
2. Length of the Selenium
Script:
Selenium Script should be identical,
contains Test Cases, where it should not have any junk code and repeated lines
of codes,by this you can know that your Test Script should have reusable code.You'can
write Selenium script as per prepare test cases but should not contain any unusual
code.
While preparing Selenium
Scripts it is very important that your script should have dynamic test data not
a static test data, You can use Test NG @Dataprovider annotation to read the
test data from Xls file and use Apache POI library to read the test data
from xlsx files.
3. Finding UI Elements
As per Selenium Scripting Guidelines,
We should not click directly on UI Elements because we should follow some steps
before clicking on UI Elements, those are
1.
Wait
for Element to Load
2.
Use
condition to verify UI Element is enable or not using isEnable() method.
3.
Use
Condition to Verify UI Elements are displaying or not using isDisplayed()
method.
4.
Make
sure UI Element is Clickable.
5.
Perform
Click Action once Element is Clickable.
This is not at all Recommended
driver.findElement(By.xpath(//input[id='firstName']))
In above code we're directly
clicking on UI Elements using Selenium test code but we're not providing any
condition to verify whether Element is visible or not, Element is clickable or not.
Just follow below sample code before identifying the Elements in UI.
Recommended Code:
WebDriverWait wait = new
WebDriverWait(driver, 10);
WebElement element =
wait.until(ExpectedConditions.presenceOfElement(By.xpath("//input[id='firstName']"));
(new
Actions(driver)).moveToElement(element).perform();
wait.until(ExpectedConditions.elementToBeClickable(element);
element.click();
As per above code we're
verifying the UI Element is present or not ,then we're performing Click
Operation on UI Elements.
4. Main Method
It is always recommended to Run
Selenium Test Scripts using main method, if you're using any Framework like TestNG,
JUnit, Using simple code you can run your Selenium Scripts using TestNG OR
JUnit Test cases under main method. So it is easy to convert your project into
Runnable JAR file.
Example:
public static void main(String[] args) {
TestListenerAdapter testla = new TestListenerAdapter();
TestNG testng = new TestNG();
testng.setTestClasses(new Class[]{SampleTests.class});
testng.run();
}
In Above main method I’m
running TestNG @Test methods using simple Test script under main method, you
people also can follow the same to run your Selenium Test Scripts.
By Above important Guidelines
will make you from beginners to Expert level in Selenium Scripting, In case you
