Key Features of Tosca

1. Test Design

Tosca provides an intuitive interface for creating and managing test cases, eliminating the need for coding expertise. The Test Case Editor is a powerful feature of Tosca that enables users to create test cases using a visual flowchart. Users can easily drag and drop test steps, connect them, and define test data values. Tosca's test design features also allow for the creation of reusable test cases, which can save time and effort in the long run.

  • Visual Test Case Design: Users can design test cases using a flowchart-like editor.

  • Reusable Test Cases: Save time and effort by creating test cases that can be reused across projects.

  • Test Data Management: Easily manage input data and expected results.

Example: Designing a Login Test Case

  • Drag and drop test steps like username entry, password entry, and login button click.

  • Link these steps with test data for data-driven testing.


How to Use Tosca For Automation Testing

Here are the steps to use Tosca for automation testing:

1. Install and set up Tosca: The first step is to install and set up Tosca on your system. You can download the trial version of Tosca from the Tricentis website and follow the installation instructions.

2. Create a new project: Once you have installed Tosca, you can create a new project. A project is a container for all your test cases, test data, and other testing artifacts.

3. Define your requirements: The next step is to define your testing requirements. You need to identify the scope of your testing, including the features and functionalities that you want to test.

4. Create test cases: Using Tosca's Test Case Editor, you can create test cases based on your testing requirements. The Test Case Editor allows you to create test cases visually, using a flowchart-like interface.

5. Define test data: Tosca allows you to define test data for your test cases. You can create test data sets that include input values, expected results, and other parameters.

6. Automate your test cases: Tosca's Test Automation Assistant allows you to automate your test cases quickly and easily. The Test Automation Assistant uses a record-and-playback approach to automate your test cases. You can record your test steps and then replay them to automate your test cases.

7. Execute your test cases: Once you have automated your test cases, you can execute them using Tosca's Execution Assistant. The Execution Assistant provides real-time feedback on test execution progress and makes it easy to identify and resolve any issues.

8. Generate reports: Tosca's reporting features provide detailed reports on your testing progress and results. You can generate custom reports based on your specific testing requirements.


Practical Use Cases for TOSCA Automation

1. Automating a Login Scenario

Here’s how to automate a login scenario using TOSCA:

  1. Scan the Application: Use TOSCA’s XScan feature to capture UI elements like username, password fields, and the login button.

  2. Create Modules: Map the scanned elements to modules in TOSCA.

  3. Design Test Case:

    • Drag and drop modules into a test case.

    • Add test data like username and password.

  4. Execute Test: Run the test case using the Execution List.


2. Data-Driven Testing

Automating tests for multiple datasets using parameterization.

  • Use Case: Testing a registration form with various input combinations like names, emails, and passwords.

  • Steps: Use TOSCA's Test Data Service (TDS) to manage data sets and link them to your test cases.

Data-Driven Login Test Using TOSCA with Python

import requests

# Test data
test_data = [
    {"username": "user1", "password": "pass1"},
    {"username": "user2", "password": "pass2"},
]

# API endpoint
url = "https://api.example.com/login"

# Loop through test data
for data in test_data:
    response = requests.post(url, json=data)
    print(f"Testing login for {data['username']}")
    assert response.status_code == 200, f"Failed for {data['username']}"
    print("Test Passed!")



3. Cross-Browser Testing

Validating web applications across different browsers to ensure compatibility.

  • Use Case: Running login tests on Chrome, Firefox, and Safari.

  • Steps: Configure TOSCA Execution List to include multiple browsers for test execution.

Automating Cross-Browser Testing with TOSCA and Selenium (Java)

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class CrossBrowserTest {
    public static void main(String[] args) {
        // Set up ChromeDriver
        System.setProperty("webdriver.chrome.driver", "path/to/chromedriver");
        WebDriver chromeDriver = new ChromeDriver();
        executeTest(chromeDriver, "Chrome");

        // Set up FirefoxDriver
        System.setProperty("webdriver.gecko.driver", "path/to/geckodriver");
        WebDriver firefoxDriver = new FirefoxDriver();
        executeTest(firefoxDriver, "Firefox");
    }

    public static void executeTest(WebDriver driver, String browserName) {
        try {
            driver.get("https://example.com");
            System.out.println("Testing on " + browserName + ": " + driver.getTitle());
            assert driver.getTitle().contains("Example Domain");
        } finally {
            driver.quit();
        }
    }
}


4. Regression Testing

Verifying that new changes in code do not impact existing functionality.

  • Use Case: Retesting critical workflows (e.g., checkout process) after implementing new features.

  • Steps: Maintain reusable test cases in TOSCA to simplify regression test execution.


5. API Testing

Validating REST or SOAP APIs with TOSCA.

  • Use Case: Testing the response of a payment gateway API for different transaction scenarios.

  • Steps: Use TOSCA's API Scan to create modules and build test cases for API requests and responses.

Example: API Testing with TOSCA and Python

import requests

# API endpoint
url = "https://api.example.com/login"

# Test data
data = {
    "username": "testuser",
    "password": "testpassword"
}

# API request
response = requests.post(url, json=data)

# Validate response
assert response.status_code == 200
print("API Test Passed!")


6. End-to-End Testing

Simulating complex user journeys across multiple systems.

  • Use Case: Automating an e-commerce workflow from login to checkout.

  • Steps: Chain modules for login, product search, cart addition, and payment in a single test case.


7. Performance Testing

Measuring the performance of an application under various loads.

  • Use Case: Analyzing how the system behaves under heavy traffic during a sale.

  • Steps: Combine TOSCA with tools like JMeter to generate load while running automated functional tests.


8. Continuous Integration (CI) Testing

Automating tests as part of the build process in a CI/CD pipeline.

  • Use Case: Running automated tests after each code commit in Jenkins.

  • Steps: Integrate TOSCA with Jenkins and trigger tests using execution lists.

Automate tests in Jenkins pipeline using a shell command to trigger TOSCA Execution List:

#!/bin/bash
echo "Running TOSCA Tests"
toscacli.exe -workspace "path/to/workspace" -executionlist "MyExecutionList"
if [ $? -eq 0 ]; then
  echo "Tests Passed"
else
  echo "Tests Failed"
  exit 1
fi
