  • Enter the name of your new project and the location to store the project data on your machine. Click OK.
  • A new project will be generated at specified location.

File–>New–> Project

Enter your Project name

Create a new project

Create your first Test Case

  • Select option to create New Test Casefrom the main Toolbar.

Test Case –> New–> Test Case

Provide the name for your test case then click OK.

Create your first test case

A new test case will be created accordingly. The test case editor is also displayed for editing.

A new test case

You can compose the test case by recording, scripting or manually entering test steps. For now, let’s quickly generate the test script using Record feature. Click on the Record icon from the main Toolbar.

While recording, actions performed on the browser will be captured and generated into test steps.

Specify the target browser to be launched by selecting from the Record dropdown list.

Your selected browser will be launched. Navigate to your website, then hover the mouse cursor over the web object to be captured.

The web object will be highlighted with a red border. An overlay pane will also be displayed at the edge of the screen to show relevant xpath info.

Select the object in the Captured Objects tree, its details will be displayed in the Object Properties section.

The method which Katalon Studio will be using to detect web elements.

Attributes – Katalon Studio automatically generate an XPath combine with objects’ properties

XPath – Katalon Studio Relative XPath. If an element cannot be consistently located using its direct attributes, Katalon Studio will identify by using its more robust neighbours.

CSS – Users are allowed to input CSS selector manually into Object Detect Editor.

Click Verify and Highlight to make sure the object can be located by Katalon Studio.

If there is a web object with matched Selector Editor value, it will be highlighted red in opened browser and message “Found X element using XPath Selector” will be displayed.

Using Xpath Selector

Click on Save to add those objects to Object Repository.

Check on those captured objects in the left pane that you would like to save into Katalon Studio.

The structure of your Object Repository is displayed on the right pane. Select the folder to add the captured objects into. Click OK when done.

Execution comes with seeing execution logs and, in many cases, you only want to execute some steps. New features have been introduced to prevent having to execute all steps:

Logs: a real-time execution raw logs when you execute test steps.

Run (with three types of run):

    • Run all steps
    • Debug: Run selected steps
    • Debug: Run from selected step

Note: You need a Katalon Studio Enterprise license to use this debugging feature in Katalon version 7.1+.

    • Run All: Execute ALL steps that are enabled on Web Recorder.
    • Debug: Run selected steps: Execute only one or many selected steps.
    • Debug: Run from selected steps: Execute the current selected step and all steps after selected one

run all steps
