Sample WebUI tests project with data-driven testing (Shopping Cart sample) in Katalon Studio

Open the Shopping Cart sample project.

In Katalon Studio, to open the Shopping Cart sample project, go to File > New Sample Project > Sample Web UI Tests Project (Shopping Cart).

Shopping Cart sample project components​

Profiles​

To open the execution profile, go to Profiles > default.

You can make and save all global variables in the execution profile. They can be utilized across test cases in your project.

Katalon creates nineteen global variables in this sample project as follows:

Custom keywords​

Katalon also makes sample custom keywords in this sample project. To see our custom keywords, in the Test Explorer panel, move to Keywords > sample. Double-click one of the following .groovy files:

Custom keywords can be re-used multiple times in test cases to carry on different actions, such as adding items to the cart, logging in, and checking out. 

Test cases​

1. Custom-keyword samples test cases
    
2. Go to Test Cases > Custom-keyword samples in the Test Explorer panel to explore the test cases for this project that use custom keywords. Double-click to launch one of the test cases below:
    

The test case Order and check out a single product contains a single product to the shopping cart, and checks-out. The sequence in this test case is as given:
 

• We utilize the loginIntoApplicationWithGlobalVariable custom keyword to:
  • Open the http://cms.demo.katalon.com website along with maximized windows.
  • Log in with the password and username described as the global variables in the execution profile.
     
• We go to the Shop page.
   
• Next, we utilized the addToCartWithGlobalVariable custom keyword to:
  • Move the product to the cart. The product is defined as a global variable in the execution profile.
  • Move to the Cart page.
  • Click on Proceed to checkout to move to the Checkout page.
     
• For the checkout step, we use the CheckoutShop custom keyword to:
  • Click on the checkout page.
  • Complete the checkout form. In the Variables tab, the checkout information is listed as a test case variable.

• Finally, we use the logoutFromApplication custom keyword to:
  • Visit the My Account section.
  • At last, click log out.
     

Data-driven samples test cases

Go to Test Cases > Data-driven samples > Order and check out multiple products in the Test Explorer panel to explore the Data-driven samples test cases for this project.

The test case Order and check out multiple products contains products from the list of product to the shopping cart, and checks-out. The sequence in this test case is as given:

• We utilize the loginIntoApplicationWithGlobalVariable custom keyword to:
  • Open the http://cms.demo.katalon.com website with maximized windows.
  • Log in with the password and username defined as the global variables in the execution profile.
     
• We move to the Shop page.
   
• Next, we want the test case to read the data files. To do so, we use the getAllData() keyword to extract product names from the product list as follows:

TestData product = findTestData(GlobalVariable.dataFile)
List<String> productList = product.getAllData().stream()
.map{data -> data[0]}/*get first column of each row in data file */
.collect(Collectors.toList())/*add collect and parse to list*/

• Then, we use the addToCart custom keyword to add extracted product names to the cart.

for(def productName : productList){
CustomKeywords.'sample.Shop.addToCart'(productName.toString(), GlobalVariable.urlProduct)
}

• At last, we use the CheckoutShopWithGlobalVariable custom keyword to:
  • Choose the Checkout page.
  • Complete the checkout form. The execution profile defines the checkout information as global variables.

Data Files​

In the Test Explorer panel, move to Data Files > Product List/Multiple Checkout to view the data files in this sample project.

Test Suites​

The sample test suites demonstrate data-driven testing in Katalon Studio. To view sample test suites, move to the Test Suite folder in the Test Explorer panel. Double-click to open one of the 3 following test suites:

1. Data-driven testing using data-binding is demonstrated in the test suite by Order and check out a single product many times. The check out and test case Order and single product with the Multiple Checkout data file is bound by this test suite. To view the crucial data, launch the Test Suite and select Show Data Binding.

2. The test suite Order and check out multiple products demonstrates data-driven testing by the Groovy script.
This test suite calls the test case Order and check out multiple products . This test case reads the Product list test data file by using the Groovy script. In the script mode of the test case Order and check out multiple products, you can see the following sample code:

TestData product = findTestData(GlobalVariable.dataFile)
List<String> productList = product.getAllData().stream()
.map{data -> data[0]}/*get first column of each row in data file */
.collect(Collectors.toList())/*add collect and parse to list*/

  /*Add extracted product names to cart*/
for(def productName : productList){
CustomKeywords.'sample.Shop.addToCart'(productName.toString(), GlobalVariable.urlProduct)
}

The test suite Order and check out with Global Variable demonstrates data-driven testing by global variables.
In Order and check out with Global Variable test suite, we call the Custom-keywords samples test cases. These test cases use custom keywords with global variables.
 

Test suite collection​

The Shopping-cart-tests - Run All Test Suites combines the 3 test suites shown above with different testing environments.

Execute selected test case or test suite/test suite collection​

To execute the test case or a test suite collection/test suite in the sample project:

• Select the test suite/test case/test suite collection you want to execute.
• Click Run.
• You can choose various browsers to execute your test in the dropdown list next to Run.
   

• See the test result in the Log Viewer tab.
