Web Testing Project with Katalon Studio

Here is a quick guide that will help you in web testing projects with Katalon Studio. Let’s have a look:

Creating Test Cases Using Record and Playback

If you wish to create test cases with record and playback, follow these steps:

  • On the main toolbar, click the New Test Case option
  • Give a name to the test case and click OK
  • Again, from the main toolbar, click Record and the record dialog will get displayed
  • To begin recording the test case, click the Record option
  • Now, on the browser, execute all of the test steps and every action performed on the browser will get recorded by Katalon Studio
  • If you want, you can Pause or Stop the recording 
  • Once done, click OK to save the recorded actions
  • A prompt will appear on your screen asking you to save captured objects into the Katalon Studi’s Object Repository, click OK
  • To execute the script, open the main Toolbar and click the Run option

You must keep in mind that all of these steps help you create and run a simple test case. 

Creating Test Cases Using Script Mode in Katalon Studio

With Katalon Studio, you can programmatically write automation tests in the Script view. Let’s find out more about it:

  • Open the browser and navigate to a website
  • Click certain control and validate if the control exists on the page
  • Close the browser

Now, follow these steps to automate the test scenario in Script view:

  • To create a test case, from the main menu, choose File and click New and then click Test Case
  • Once the test case is created, switch to the Script view
  • Test steps that have been specified in the Manual view get automatically translated to Groovy script in the Script view

In a test script, the import statement lets a reference to classes be used. To see all of the default imported classes, expand the Import section. In each import statement, the name after ‘as’ is an alias for the class. For each class, you can change the alias. 

Also, all of the keywords are grouped into WebService, Mobile, and WebUP packages accordingly. To view these functions and packages from the imported classes, press CTRL + Space.

  • In this situation, you will have to create a web application test script; thus, you can use the Web UI built-in keywords
  • To use them, enter WebUI syntax in the editor
  • Once you’ve entered the dot character (.), all of the inbuilt keywords and their description for WebUI testing will appear on your screen
  • Choose the Open Browser keyword and it will navigate to the specific URL (if you’ve provided it) 
  • A popup screen will show the details for the chosen keyword
  • Type in the Navigate to URL keyword and it will navigate you to a specific URL 
  • Enter the Click and this keyword is meant to represent the click action on the given object, you will have to specify the object for this action
  • In Object Repository, to refer to an object, you can follow this syntax: findTestObject ( ‘ {Object ID} ‘ ) Here, the Object ID is the object’s ID in Katalon Studio that can be found from the Properties dialog
  • Enter the Verify Element Present keyword and it will validate if a specific object is showcased on the executing browser
  • Add in the Close Browser keyword and save the test case

Creating Test Cases Using Manual Mode

If the test cases comprise keywords that represent users’ actions on the Applications Under Test (AUT), the Katalon Studio supports keywords-driven testing. This lets those with less programming experience to generate automation tests with ease. With this step-by-step guide, you can create test cases using manual mode:

  • Open the browser and go to a website
  • Click on a specific control and validate if it exists on the page
  • Close the browser

Now, follow these steps to automate the test scenario in manual mode:

  • To create a test case, choose File and then New and Test Case from the main menu
  • Give a name to the test case and click OK
  • Once it is created, it will get opened in the Manual view, which will let you define steps for the test case seamlessly with little programming skills
  • From the command toolbar, choose Add > Web UI Keyword
  • Choose the Open Browser keyword and it will open a browser and will navigate you to a specific URL (if provided)
  • Add the Navigate to URL keyword and it will navigate to a specific URL

On the Input cell, double click to offer additional data for the keyword

  • The Input dialogue will be displayed where every row will represent one parameter, such as
NoParameter order for the selected keyword
Param NameThe name of the parameter.
Param TypeThe data type of the parameter, such as Test Data Value, Variable or String
Value TypeThe type of input value, such as Test Data Value, Variable or String 

The input value for this parameter.

Input value varies based on the specified Value Type

  • In the Value column, enter any URL and click OK
  • Add the Click keyword and it will represent a click action on an object, double click on the Object cell to open the Test Object Input dialogue
  • All of the captured objects in the Object Repository will be displayed in the Test Object Input dialog, choose your object and click Ok
  • Add the Verify Element Present keyword and it will validate if a specific object will be displayed on the executing browser
  • Add the Close Browser keyword and save the test case
  • To execute the test case, click Run in the main toolbar

And, you are done.

Why Choosing Katalon Studio Over Selenium?

Here are some reasons that will help you make a better decision between Katalon Studio and Selenium:

  • Katalon Studio conceals all of the technical complications behind the scene and offers a friendly UI with the manual mode. Moreover, it still retains required weapons for more technically powerful users who can dig deeper into coding with scripting mode that completely supports the conveniences of development, such as debugging, code suggesting, and syntax highlighting
  • With Selenium, you will have to go through technical guidelines for the API and integrate the same into a preferred programming language and an IDE. On the contrary, Katalon Studio is developed as a unified bundle that comprises every required thing, such as web drivers to drive browsers, Android SDK, Java, and needed dependencies. All you will have to do is download and install the tool to get started
  •  While Selenium needs you to build reusable and common actions on your own, Katalon Studio comprises pre-defined sets of commonly used actions or keywords. You will find them satisfactory enough to begin implementing most of the test cases. 

Why Choosing Katalon Studio Over QTP/UFT or Test Complete?
