Introduction to custom keywords in Katalon Studio

Important:

• You have a Katalon Studio Enterprise license.

In addition to built-in keywords, you can define custom keywords to extend the capabilities of Katalon Studio. Once created, custom keywords can be used when executing test cases like other built-in keywords.

Create a keyword package

A package is a namespace that organizes a set of related classes and interfaces.

You can keep things organized by grouping related classes and interfaces into packages.

To create a keyword package, do as follows:

1. From Tests Explorer, right-click Keywords folder and select New > Package.
   
   The New Keyword Package dialog is displayed.

   

2. Enter a name for your package, then click OK.

In the Tests Explorer section, a new package is created accordingly.

Create a custom keyword

To create a custom keyword, do as follows:

1. From Tests Explorer, right-click Keywords folder and select New > Keyword.
   
   The New Keyword dialog is displayed.

   

2. Enter a class name and specify a package for the keyword. Click OK.
   By default, a class name cannot start with a number, contain spaces, or have special characters. You can follow the Java naming convention: start with a lowercase letter, then capitalize the first letter of every following word (for example, newCustomKeyword).
   Note:

   • You can generate sample custom keywords for Web, Mobile, and API Testing. Refer to Sample Custom Keywords in Katalon Studio.

   A new custom keyword is created under the specified package.

3. Enter the following code snippet in your class to define a custom keyword:

   @Keyword (keywordObject = "<category_name>")
   def keywordName(parameters…) {
   // enter your code here
   // you can use either Groovy or Java
   }

   Item	Description	Required
   @Keyword	The annotation to indicate that the block of code below is the definition of a keyword.	Yes
   keywordObject	The category of your custom keyword.	No
   keywordName	The name for your custom keyword.	Yes
   parameters	The list of parameters to be used in the custom keyword.	No

   For example:

   

   Custom Keywords in Keywords Browser are put in alphabetical order, and you can categorize them. The category name should be declared via keywordObject with the same mechanism as the built-in keywords.

   The sample below describes a keyword with the "Browser" category:

   @Keyword(keywordObject = "Browser")
   def refreshBrowser() {
   }

   In the Keywords Browser:

   

4. When you are done, save the keyword file.

Use custom keywords in the manual view

To use your defined custom keywords in the manual view of a test case, do as follows:

1. Open a test case in the manual view. Select Add > Custom Keyword.
   
2. A new test step is added. Select your preferred custom keyword.
   

Your custom keyword is added as a test step.

Use custom keywords in the script view

To use your defined custom keywords in the script view of a test case, do as follows:

1. The Class CustomKeywords of Katalon Studio allows you to access all custom keywords. Enter the following syntax into the script editor:

   CustomKeywords.
2. After you type the dot character, the Content Assist function is invoked. All the custom keywords defined in your test project are displayed as below:
   
3. Select your custom keyword and provide all parameters as required.

You've added your custom keyword in the script view.
