Silk Test Automation: Enterprise Testing for Web, Mobile, and Desktop

Silk Test Automation: Enterprise Testing for Web, Mobile, and Desktop

Silk Test has been around since the 1990s — which in software years is ancient. It's been through several owners (Segue Software → Borland → Microfocus → OpenText) and has evolved considerably, but it remains a fixture in large enterprise test automation programs, particularly in regulated industries and organizations with significant legacy test investments.

This guide covers Silk Test for teams evaluating it as a new tool and for those inheriting an existing Silk Test installation.

What Is Silk Test?

Silk Test (now branded as OpenText Silk Test) is an automated testing platform for web, mobile, desktop, and API testing. It uses a proprietary scripting language called Silk Test Basic (similar to VBA) as well as Java.

Key characteristics:

  • Strong cross-browser testing support
  • Native mobile testing (iOS, Android)
  • Desktop app testing (Windows, Java)
  • SAP and Salesforce-specific support
  • Enterprise licensing model with support contracts

Silk Test Products

The Silk Test family includes several products:

Silk Test Workbench: The primary IDE for record-and-playback and scripting. Uses Visual Basic-style syntax.

Silk4J: Eclipse plugin for writing Silk Test automation in Java. Popular with development teams already using Java.

Silk4NET: Visual Studio extension for .NET/C# teams.

Silk Central: Test management platform that orchestrates Silk Test execution, manages requirements, and aggregates results. Often purchased alongside Silk Test.

For this guide, we focus primarily on Silk Test Workbench and Silk4J.

Core Concepts

Test Application Profile (TAP)

Before writing tests, you create a Test Application Profile that tells Silk Test how to connect to your application — the URL for web apps, the executable path for desktop apps, or device configuration for mobile.

Object Map

Like other enterprise testing tools, Silk Test uses an Object Map to centralize element locators. This decouples test logic from element identifiers, making maintenance easier when the UI changes.

Test Classes

Web testing uses the BrowserWindow and element classes. Desktop testing uses technology-specific classes for Win32, WPF, JavaAWT, etc.

Writing Tests in Silk Test Workbench

Silk Test Workbench uses a Visual Basic-like syntax:

' Login test
Sub TestLogin()
    Dim browser As BrowserWindow
    Set browser = BrowserWindow.Open("https://app.example.com/login")
    
    ' Find elements
    Dim emailField As TextField
    Set emailField = browser.Find("//input[@name='email']")
    
    Dim passwordField As TextField
    Set passwordField = browser.Find("//input[@name='password']")
    
    Dim submitButton As PushButton
    Set submitButton = browser.Find("//button[@type='submit']")
    
    ' Perform actions
    emailField.SetText("test@example.com")
    passwordField.SetText("password123")
    submitButton.Click()
    
    ' Wait and assert
    Dim dashboard As DomElement
    Set dashboard = browser.FindByXPath("//div[@data-testid='dashboard']", 10000)
    Assert.IsTrue dashboard.Exists(), "Dashboard should be visible after login"
End Sub

Writing Tests in Silk4J (Java)

For Java developers, Silk4J integrates directly with JUnit:

import com.borland.silktest.jtf.*;
import com.borland.silktest.jtf.common.*;
import org.junit.*;

public class LoginTest {
    
    private BrowserWindow browser;
    
    @Before
    public void setUp() {
        Desktop desktop = new Desktop();
        browser = desktop.open("https://app.example.com/login");
    }
    
    @Test
    public void testSuccessfulLogin() {
        // Find elements
        TextField emailField = browser.find("//input[@name='email']");
        TextField passwordField = browser.find("//input[@name='password']");
        PushButton submitButton = browser.find("//button[@type='submit']");
        
        // Interact
        emailField.setText("test@example.com");
        passwordField.setText("password123");
        submitButton.click();
        
        // Assert
        DomElement dashboard = browser.findByXPath(
            "//div[@data-testid='dashboard']"
        );
        assertTrue("Dashboard visible after login", dashboard.exists());
        
        String welcomeText = browser.findByXPath(
            "//h1[@data-testid='welcome-heading']"
        ).getTextContent();
        assertTrue("Welcome message shown", welcomeText.contains("Welcome"));
    }
    
    @After
    public void tearDown() {
        if (browser != null) {
            browser.close();
        }
    }
}

Cross-Browser Testing

Silk Test supports Internet Explorer, Edge, Chrome, Firefox, and Safari. Configure the target browser in the TAP:

// Set up for Chrome
BrowserType browserType = BrowserType.Chrome;
Desktop desktop = new Desktop();
browser = desktop.open("https://app.example.com", browserType);

For cross-browser test matrices, parameterize the browser type:

@RunWith(Parameterized.class)
public class CrossBrowserLoginTest {
    
    @Parameter
    public BrowserType browserType;
    
    @Parameters(name = "{0}")
    public static Collection<Object[]> browsers() {
        return Arrays.asList(new Object[][] {
            { BrowserType.Chrome },
            { BrowserType.Firefox },
            { BrowserType.Edge }
        });
    }
    
    @Test
    public void testLogin() {
        Desktop desktop = new Desktop();
        BrowserWindow browser = desktop.open("https://app.example.com/login", browserType);
        
        // Test logic here — same for all browsers
        browser.find("//input[@name='email']").setText("test@example.com");
        browser.find("//input[@name='password']").setText("password123");
        browser.find("//button[@type='submit']").click();
        
        assertTrue(browser.findByXPath("//div[@id='dashboard']").exists());
        browser.close();
    }
}

Mobile Testing

Silk Test supports testing native iOS and Android apps through integration with device farms. You can test against physical devices or simulators/emulators.

Configure mobile testing in the TAP with device connection details and app bundle information. The same Java API used for web testing works for mobile, with mobile-specific gesture methods:

// Mobile-specific interactions
MobileDevice device = MobileDevice.connect("device-id");
MobileApplication app = device.installApp("/path/to/app.apk");
app.launch();

// Tap, swipe, etc.
app.tap(app.find("//android.widget.Button[@text='Login']"));
app.swipeLeft(app.find("//android.widget.ScrollView"));

SAP and Salesforce Testing

Silk Test includes recognition for SAP GUI components and Salesforce Lightning components — areas where generic web automation tools struggle because standard element selectors don't map cleanly to SAP's custom UI rendering.

For SAP testing, Silk Test uses SAP-specific object types that expose SAP UI element properties directly:

' SAP-specific interaction
Dim sapButton As SapButton
Set sapButton = browser.Find("SAPButton:Save")
sapButton.Click()

Recording Tests

Silk Test Workbench includes a recorder that captures your interactions and generates test steps. The recorder is useful for:

  • Quick test scaffolding for repetitive workflows
  • Capturing element locators for the Object Map
  • Onboarding team members who don't write tests from scratch

Recorded tests usually need cleanup — the recorder captures every mouse movement and intermediate state. Edit the generated code to remove noise and add assertions.

Data-Driven Testing

Silk Test supports data-driven testing through Excel files, CSV, and database connections:

@DataDriven(source = "test_data/checkout_scenarios.xlsx")
public class CheckoutTest {
    
    @DataDrivenField
    public String productId;
    
    @DataDrivenField  
    public int quantity;
    
    @DataDrivenField
    public String expectedTotal;
    
    @Test
    public void testCheckout() {
        // productId, quantity, expectedTotal populated from Excel for each row
        Desktop desktop = new Desktop();
        BrowserWindow browser = desktop.open("https://shop.example.com");
        
        browser.find("//input[@id='search']").setText(productId);
        browser.find("//button[@id='search-btn']").click();
        // ... rest of test
    }
}

CI/CD Integration

Silk Central serves as the orchestration layer. Tests run from Silk Central can be triggered via REST API from any CI tool.

Direct squishrunner-style execution is also available through Silk Test's command-line interface:

# Run a specific test in headless mode
silktest --config=app.tap --test=LoginTest --browser=chrome --headless

Jenkins pipeline example:

pipeline {
    agent any
    stages {
        stage('Run Silk Tests') {
            steps {
                bat '''
                    cd "C:\\Program Files\\OpenText\\SilkTest"
                    SilkCentralWebTestRunner.exe ^
                        --host=silk-central.example.com ^
                        --port=19120 ^
                        --token=%SILK_CENTRAL_TOKEN% ^
                        --testplan=42 ^
                        --build="Build-${BUILD_NUMBER}"
                '''
            }
            post {
                always {
                    junit 'results/**/*.xml'
                }
            }
        }
    }
}

Maintaining Tests Over Time

Enterprise applications change frequently. Strategies for keeping Silk Test suites healthy:

Use the Object Map religiously. Tests that hardcode locators are a maintenance burden. Every element should go through the Object Map.

Abstract common operations. Login, navigation, and data setup that appears across many tests belongs in shared functions or base classes.

Review test failures weekly. Don't let failing tests accumulate. A failing test that stays red becomes noise — developers start ignoring it.

Use test isolation. Tests that depend on each other's state are brittle. Each test should set up its own preconditions and clean up afterward.

Treat warnings as errors. Silk Test warnings about deprecated locators or changed element properties are early signals of upcoming failures. Address them before they become broken tests.

Silk Test vs Modern Alternatives

Honest comparison for teams evaluating their options:

Silk Test vs Playwright/Selenium: Modern browser automation frameworks are free, have larger communities, and better documentation. For web-only testing, Playwright is almost always the better choice for new projects. Silk Test makes sense when you have existing investment or need desktop/mobile/SAP coverage in one tool.

Silk Test vs TestComplete: Both are SmartBear/OpenText commercial tools. TestComplete has a more modern UI and broader language support. Silk Test has stronger SAP support.

Silk Test vs UFT/ALM: Mercury/HP/Micro Focus/OpenText UFT is the other major enterprise testing tool. UFT uses VBScript; Silk Test uses VB-like syntax for Workbench and Java for Silk4J. UFT has stronger SAP support; Silk Test has better Java support. Both are enterprise tools with similar pricing models.

When Silk Test Makes Sense

Silk Test is appropriate when:

  • You have an existing Silk Test investment and trained team
  • You need SAP GUI automation
  • You need a single tool for web, desktop, and mobile in an enterprise context
  • Regulatory compliance requires commercial tool support contracts

For new greenfield projects without specific SAP or legacy desktop requirements, investing in free, open-source tooling (Playwright, Appium, pytest) is usually preferable.

Summary

Silk Test is a mature enterprise test automation platform with deep support for web, mobile, desktop, and SAP applications. Its Java API (Silk4J) and .NET integration make it approachable for development teams, while Silk Test Workbench accommodates non-programmers.

The commercial cost and learning curve are real barriers. For organizations with existing Silk Test deployments, modernizing with Silk4J and integrating with current CI/CD pipelines can extend the value of existing assets while improving developer experience.
