Locating Strategies- (By ID)
In this section, you will learn how to locate a particular web element using the value of its id attribute.
Let us consider a test case in which we will automate the following scenarios:
We will create our test case step by step in order to give you a complete understanding of how to use Locators to identify and locate a particular web element.
Step1. Launch Eclipse IDE and open the existing test suite "Demo_Test" which we have created in earlier sessions of this tutorial.
Step2. Right click on the "src" folder and create a new Class File from New > Class.
Give your Class name as "Locator_One" and click on "Finish" button.
Step3. Let's get to the coding ground.
Here is the sample code to set system property for Gecko driver:
Here is the sample code to initialize gecko driver using DesiredCapabilities class.
Combining both of the above code blocks, we will get the code snippet to launch Firefox browser.
Here is the sample code to navigate to the desired URL:
The complete code till now will look something like this:
Step4. Now we will try to locate the desired web element by using the value of its id attribute. In Selenium, locating a particular web element involves inspection of its HTML codes.
Follow the steps given below to locate the Text box on the sample web page.
The Java Syntax for locating a web element using its id attribute is written as:
Therefore, for locating the text box on the sample web page we will use the value of its id attribute as:
Similarly, for locating the Submit button on the sample web page we will use the value of its id attribute as:
To automate our third, fourth and fifth test scenario, we need to write the code which will click on the Text box, type the desired values on the text box and click on the submit button.
Here is the sample code to click on the Text box and type values as "JavaTpoint".
And the following code snippet will click on the Submit button:
Thus, our final test script will look something like this:
The following screenshot shows the Eclipse window for our test script.
Step6. Right click on the Eclipse code and select Run As > Java Application.
Upon execution, the above test script will launch the Firefox browser and automate all the test scenarios.
