In addition to built-in keywords, users can define custom keywords to extend the capability of Katalon Studio. Once created, custom keywords can be used when implementing test cases just like other built-in keywords. 

 

Create a Package

A package allows you to group custom keywords into different categories. 

  1. Select File > New > Package from the main menu. The New Keyword Package dialog will be displayed. Enter the name for your package and click OK.


  2. A new package is created under Keywords of Katalon Studio accordingly.

 

Create a Custom Keyword

  1. Select File > New > Keyword from the main menu. The New Keyword dialog will be displayed. Enter the name for your keyword and specify a package for the keyword. Click OK.


  2. A new keyword is created under the specified package accordingly.


  3. Enter the following block of code in your class to define one custom keyword:

    @Keyword
    def keywordName(parameters…) {
       // enter your code here
       // you can use either Groovy or Java      
    }

    where:

    ItemDescription
    @KeywordThe annotation to indicate that the block of code below is the definition of a keyword.
    keywordNameThe name that you would like to use for your custom keyword
    parametersThe list of parameters that would be used in the custom keyword

    For example:

  4. Save the Keyword file when you're done.

Custom keywords in Manual view

Follow the steps below in order to use your defined custom keywords in Manual view of a Test Case:

  1. Open a test case in Manual view, then select to add Custom Keyword from command toolbar.


  2. A new test step is added with a list of all defined custom keywords. Select your recently created keyword here.

 

Custom keywords in Scripting view

Follow the steps below in order to use your defined custom keywords in Scripting view of a test case:

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

    CustomKeywords.
  • The Content Assist function will be invoked immediately after you type the dot character. Content Assist provides users with the context-sensitive suggestions for code completion. Therefore, all the custom keywords defined in your test project will be displayed as below:

  • Select the recently created keyword and provide all parameters as required.

The following API docs may prove useful when working with custom keywords:

ClassMethodDescription
Driver FactorygetWebDriver()Get the current active web driver.
Test ObjectaddProperty(String name, ConditionType condition, String value)Add a new property to the test object
setProperties(List<TestObjectProperty> properties)Set the properties of the test object
getObjectId()Get object ID.
findPropertyValue(String name, boolean caseSensitive)Find the value of a property using the property name
Keyword UtillogInfo(String message)Log message as info
markError(String message)Mark a keyword to be error
markErrorAndStop(String message)Mark a keyword to be error and stop execution
markFailed(String message)Mark a keyword to be failed and continue execution
markFailedAndStop(String message)Mark a keyword to be failed and stop execution
markPassed(String message)Mark a keyword to be passed
markWarning(String message)Mark a keyword to be warning

 

Handle Databases

With custom keywords, you can connect to a database as well as perform other data queries. 

Below is a sample demonstrating how to create custom keywords for:

  • Establishing database connection
  • Executing data query
  • Closing the connection


private static Connection connection = null;

	/**
	 * Open and return a connection to database
	 * @param dataFile absolute file path  
	 * @return an instance of java.sql.Connection
	 */
	@Keyword
	def connectDB(String dataFile){
		//Load driver class for your specific database type
		Class.forName("org.sqlite.JDBC")
		String connectionString = "jdbc:sqlite:" + dataFile
		if(connection != null && !connection.isClosed()){
			connection.close()
		}
		connection = DriverManager.getConnection(connectionString)
		return connection
	}
	
	/**
	 * execute a SQL query on database
	 * @param queryString SQL query string
	 * @return a reference to returned data collection, an instance of java.sql.ResultSet
	 */
	@Keyword
	def executeQuery(String queryString) {
		Statement stm = connection.createStatement()
		ResultSet rs = stm.executeQuery(queryString)				
        return rs
	}

	@Keyword
	def closeDatabaseConnection() {
		if(connection != null && !connection.isClosed()){
			connection.close()
		}
		connection = null
	}

	/**
	 * Execute non-query (usually INSERT/UPDATE/DELETE/COUNT/SUM...) on database	
	 * @param queryString a SQL statement
	 * @return single value result of SQL statement
	 */
	@Keyword
	def execute(String queryString) {
		Statement stm = connection.createStatement()
		boolean result = stm.execute(queryString)
		return result
	}

You can add the sample code above to your keyword file and modify the details as appropriated.
