Selenium is free. TestResults isn’t. So why would an organisation pay for a test automation tool when its IT team could build automated tests using Selenium?

It’s a fair question, especially when the IT department already has developers familiar with Selenium WebDriver. The framework is open-source, supports multiple programming languages, works across major browsers, and has an extensive community behind it. For many QA teams, Selenium has been the foundation of their test automation strategy for years.

But comparing the two tools based on licensing costs alone overlooks a more important question: What exactly does the organisation need to test?

We’ve compared TestResults and Selenium across their technical capabilities, application coverage, execution infrastructure, test management, maintenance requirements, and total cost of ownership. The comparison is particularly relevant for regulated industries such as banking, insurance, and healthcare, where a single business process can involve several applications built on different technologies.

A customer might submit a payment through an online banking portal, while the transaction is processed in a legacy system, reviewed through a Citrix application, and confirmed through a generated PDF. Selenium can automate the browser-based interactions. Testing the complete process, however, requires additional automation technologies and integrations.

TestResults takes a different approach, supporting automated testing workflows across web, desktop, Citrix, mobile, and legacy applications. So, when is Selenium sufficient, and when does a broader test automation platform make more sense?

TestResults vs Selenium: A technical comparison

Selenium and TestResults aren't identical categories of software. Selenium is a well-established browser automation framework, particularly useful for development teams testing web applications. TestResults goes further by enabling end-to-end test automation across different application technologies, including web, desktop, Citrix, mobile, and legacy systems, without requiring teams to build separate automation frameworks for each environment.

For enterprises managing complex business processes, this difference matters. TestResults provides a broader approach to automation, reducing the need for custom integrations and making it easier to test complete workflows rather than individual browser interactions.

TestResults vs Selenium: Feature comparison

The biggest advantage of TestResults is its ability to automate complete business processes without relying on a collection of separate automation tools.

Selenium remains a strong option for browser-focused testing, particularly for teams with the development resources to build and maintain their own frameworks. But for organisations working with multiple application technologies, TestResults addresses a much larger part of the testing process within one platform.

This is especially relevant in banking, insurance, and healthcare, where testing a web interface alone isn't enough to confirm that a transaction, claim, or patient workflow has been completed correctly across connected systems.

Selenium helps teams automate browser interactions. TestResults helps organisations validate the business processes behind them.

1. How Selenium test automation works

Selenium is one of the most established tools for UI test automation. Its ecosystem includes Selenium WebDriver, Selenium Grid, and Selenium IDE, each addressing a different part of browser-based testing.

Selenium WebDriver is the main component developers use to write tests that interact with web browsers. It communicates through the W3C WebDriver protocol, allowing test scripts to control browser interactions such as navigation, form submission, clicking elements, and validating page content.

A typical Selenium test automation workflow involves writing test code, executing it through a testing framework, sending commands to a browser driver, and evaluating the results through assertions. For example, a Python test could open a login page, locate username and password fields using HTML IDs, enter credentials, submit the form, and wait for a dashboard element to appear.

For web application testing, this approach is effective and gives developers considerable control over test behaviour, execution, and validation.

Selenium Grid and cross-browser testing

Selenium Grid allows QA teams to distribute automated tests across multiple machines, browsers, and operating systems. Instead of running every test sequentially on one machine, teams can execute tests in parallel across different browser environments, including Chrome, Firefox, and Edge.

Selenium Grid 4 uses components such as the Router, Distributor, Session Map, and Nodes to coordinate browser sessions and test execution. Teams can also use cloud-based browser and device testing services to expand environment coverage without maintaining every machine internally.

However, Selenium Grid doesn’t expand WebDriver’s native scope beyond browser automation. It helps teams run automated tests across browser environments, not arbitrary desktop or legacy applications.

2. Cross-application testing: The biggest difference between Selenium and TestResults

Most organisations don’t operate exclusively through web applications. A bank might use a customer-facing web portal, a desktop application for internal operations, a Citrix-hosted system for approvals, and an AS/400 platform for core banking processes. An insurance company might process claims across a customer portal, policy administration software, and document-generation systems.

Testing each application independently doesn’t necessarily verify that the complete business process works.

What Selenium can and cannot automate natively

Selenium WebDriver is designed to automate web browsers. It can interact with HTML elements, navigate between pages, submit forms, and validate browser-accessible behaviour. But it doesn’t natively automate general desktop applications, Citrix-hosted interfaces, or terminal-based legacy systems.

Organisations can extend their testing framework using third-party tools. Appium can support mobile application automation, while desktop automation libraries can interact with certain Windows applications. APIs and database queries can also validate downstream processes. Selenium can participate in a broader end-to-end testing architecture, but these capabilities require additional technologies and integration work.

For enterprises managing several application types, the distinction between browser-level automation and end-to-end software testing becomes important. The first validates interactions within a browser, while the second needs to establish whether the complete business process works as expected.

How TestResults approaches cross-application automation

TestResults is designed to automate workflows across different application types. Its visual automation capabilities, including Visual DOM, ReverseOCR, and visual matching, allow automated tests to interact with interfaces that don’t expose conventional browser DOM elements.

This is particularly useful for Citrix environments, desktop applications, and legacy systems. Instead of relying exclusively on HTML attributes or browser-specific selectors, TestResults can use visual information to identify and interact with interface elements.

Consider a banking payment workflow:

· Online banking portal: Customer submits a payment.
· Core banking system: Transaction is registered and processed.
· Citrix or desktop application: Internal approval is completed.
· PDF and email confirmation: Final output is validated.

With Selenium, the organisation could automate the browser interactions and develop integrations for the remaining systems. With TestResults, the workflow can be approached through a platform designed to support automation across those different interfaces. The difference becomes more significant as the number of applications and integration points increases.

3. Object recognition, page structure, and test stability

Reliable object recognition is essential for automated UI tests. When a test needs to click a button or enter input data, the automation tool must identify the correct interface element. Selenium and TestResults use different approaches to this problem.

Selenium locators and page objects

Selenium commonly identifies elements using IDs, CSS selectors, XPath expressions, and other attributes exposed by the web application’s DOM. A Selenium test might locate a payment submission button using a CSS selector such as [data-testid="submit-payment"] and then execute a click command.

This approach can be reliable when developers provide stable identifiers. However, tests using fragile selectors can break when the page structure changes. Selenium teams often use the Page Object Model to centralise locators and interactions, allowing developers to update one component instead of modifying every affected test case.

Explicit waits, stable test data, and independent test cases also help reduce flaky tests. A well-designed Selenium framework can be highly reliable, but DOM-based automation depends on access to the browser’s page structure.

TestResults and visual object recognition

TestResults uses visual recognition technologies to identify interface elements across different application environments. This matters when applications don’t expose accessible HTML elements or automation runs through a remote interface.

For example, a Citrix application may display a button without exposing its underlying object structure to the local automation environment. Visual recognition provides another way to identify and interact with that control.

Visual automation also requires maintenance. Changes in layout, resolution, scaling, or application behaviour can affect recognition. Neither approach eliminates maintenance; TestResults provides recognition capabilities for environments where Selenium’s conventional browser locators aren’t available.

4. Test execution and managing growing test suites

As test suites grow, execution infrastructure becomes increasingly important. A small QA team might run automated tests locally, while a larger organisation may execute thousands of test cases across different environments and release pipelines.

Running Selenium tests at scale

Selenium Grid supports parallel execution across multiple browser sessions. Combined with pytest, JUnit, NUnit, or TestNG, it allows teams to organise test suites and run automated tests as part of CI/CD workflows. A team could execute smoke tests after every deployment and run a larger regression suite overnight.

Parallel execution introduces operational requirements: isolated test data, stable environments, sufficient resources, and predictable application states. If two tests modify the same customer account, one might fail because of changes made by the other. Browser versions, drivers, and dependencies also need to remain compatible.

Selenium Manager helps automate browser and driver management, reducing configuration effort without eliminating broader infrastructure maintenance.

Execution across different application technologies

A browser test can usually run in an isolated browser session. A desktop test might require an interactive operating system session, specific window positioning, or a consistent screen resolution. Citrix testing may depend on session availability, display configuration, and remote access permissions. Legacy applications can introduce additional constraints.

TestResults supports automation across these environments, although organisations should verify parallel execution capabilities, infrastructure requirements, and session management for their deployment. The question is not simply how many tests can run simultaneously, but how reliably complete workflows can execute across all required systems.

5. Selenium test management, reporting, and automated test results

Automating execution is only one part of software testing. QA teams also need to organise test cases, understand failures, monitor test coverage, and connect results to requirements and defects. This becomes particularly important in regulated industries, where organisations may need to demonstrate what was tested and retain evidence.

How Selenium test results are generated

Selenium WebDriver doesn’t provide a complete test management platform or a native reporting and assertion engine. Developers typically use JUnit, NUnit, TestNG, or pytest to execute Selenium tests, evaluate assertions, and generate structured reports, including JUnit-compatible XML files.

An XML report might record that three payment tests were executed, two passed, and one failed because a confirmation message wasn’t found. Such automated Selenium test results can be imported into CI/CD systems or reporting platforms. Additional tools provide screenshots, logs, histories, and dashboards.

Testiny, for example, can centralise manual and automated test results within one test management platform. But Selenium doesn’t automatically connect results to business requirements or regulatory controls; that requires configuration and integrations.

TestResults and test management integrations

TestResults supports integrations with Jira, Xray, Jenkins, Azure DevOps, and GitLab. These allow automated testing workflows to connect with existing development and test management processes. An organisation may need to associate a payment test with a requirement, execute it during regression testing, and make results available for release review.

The precise reporting and evidence capabilities depend on configuration and connected systems. A technical evaluation should examine the following:

A passing test alone doesn’t necessarily provide enough information to support a release decision. These requirements matter when evaluating enterprise testing tools for compliance-heavy software environments, where auditability and traceability can be just as important as execution.

6. Test coverage: Why more automated tests don’t always mean better testing

Test automation is often measured through the number of automated test cases, execution frequency, or pass rates. These metrics are useful, but they don’t necessarily indicate whether the most important business processes are covered.

An organisation could maintain thousands of Selenium tests validating browser interactions while leaving critical downstream systems untested. A payment test might verify that the browser displays a successful confirmation message. But was the payment processed correctly in the core banking system? Was the transaction duplicated? Was the correct confirmation document generated?

Technical coverage vs business risk coverage

Technical coverage focuses on which components, interfaces, or requirements have been exercised. Business risk coverage considers whether testing addresses failures with the greatest operational or financial consequences. Both matter. A cosmetic issue on a settings page and a duplicate payment execution shouldn’t receive the same testing priority.

This distinction also appears in our analysis of five years of software testing research, which examines whether increasing automation activity actually translates into better testing outcomes.

Where Leonidas fits into the process

TestResults also offers Leonidas, a risk-based test case generation and prioritisation tool. Leonidas analyses specifications, identifies test cases, and scores them according to factors such as potential damage and frequency. This helps teams determine which test cases deserve attention before investing in automation.

Selenium and TestResults address test execution, while Leonidas helps with test selection and prioritisation. For organisations with limited testing resources, the objective shouldn’t simply be to generate more tests, but to automate the tests that provide the most useful information about business risk.

While risk-based testing has long been recognised as an effective approach, applying it consistently requires teams to connect test cases to actual business consequences.

7. The real cost of Selenium vs TestResults

Selenium is open-source and can be used without commercial licensing fees. For teams already familiar with Selenium automation, this is a significant advantage. However, the total cost of test automation includes engineering time for initial development, maintenance, infrastructure, reporting, and integrations. When testing extends beyond web applications, additional tools may be necessary.

Why licensing costs don’t tell the whole story

Consider two organisations. The first develops a browser-based SaaS product and has an experienced Selenium team. Its automated tests cover web interfaces, and its CI/CD pipeline already handles execution and reporting. Selenium may be the most economical option.

The second operates a banking platform involving web applications, desktop software, Citrix, and legacy systems. Its testing team needs to validate complete business processes across these technologies. A Selenium-based solution would require additional automation frameworks, integrations, and maintenance.

A commercial platform supporting multiple application technologies may reduce custom development, but that doesn’t automatically make TestResults cheaper. Compare total cost of ownership, including development, maintenance, infrastructure, training, licensing, and support. A proof of concept should measure representative workflows and maintenance after realistic application changes.

8. Can AI make Selenium a complete enterprise test automation solution?

AI coding assistants can generate Selenium scripts, suggest locators, refactor page objects, and help developers investigate failed tests. These capabilities can reduce effort in building and maintaining browser automation.

However, AI-generated test code still depends on the underlying automation tools. An AI assistant can generate a Selenium test for a web application or code that interacts with APIs, databases, and other libraries. But Selenium WebDriver itself remains designed for browser automation. Citrix applications and legacy terminals still require appropriate automation mechanisms.

Generating tests isn’t the same as validating business processes

Consider a requirement that a payment must not be processed twice. An AI assistant might generate a Selenium test that submits the form twice and checks whether the browser displays an error. But that doesn’t prove the core banking system prevented duplicate processing.

The actual business requirement concerns the final transaction state, not just the browser response. AI can make test development faster, but it doesn’t automatically guarantee that the resulting tests cover the systems and risks that matter.

9. When should organisations choose Selenium or TestResults?

The right choice depends on the organisation’s applications, testing requirements, and existing technical resources.

Selenium makes sense when:

· Most automated tests involve web applications.
· The team has developers experienced with Selenium WebDriver.
· Cross-browser testing is a primary requirement.
· The organisation wants control over its testing framework.
· Existing CI/CD and test management integrations meet its needs.

For a team testing a modern browser-based application, Selenium can provide a reliable and cost-effective automation foundation.

TestResults makes sense when:

· Business processes span web, desktop, Citrix, and legacy applications.
· End-to-end testing needs to validate outcomes across multiple systems.
· Maintaining separate automation frameworks creates unnecessary complexity.
· Testing teams need visual automation for interfaces without accessible DOM elements.
· The organisation operates in a regulated environment where critical workflows require broader coverage.

For enterprises managing multiple application technologies, TestResults provides an approach designed around complete business workflows.

Can Selenium and TestResults be used together?

Yes. A team might continue using Selenium for browser smoke tests and developer-owned regression suites while using TestResults for cross-application workflows. This retains existing Selenium investments while addressing requirements that extend beyond the browser. The important consideration is useful coverage without unnecessary duplication.

Beyond the browser: Choosing the right test automation approach

Our comparison shows that Selenium and TestResults solve different testing problems. Selenium provides a mature, flexible foundation for browser automation. Its open-source ecosystem, cross-browser support, and integration options make it a strong choice for teams focused on web application testing.

But enterprise testing becomes more complicated when critical business processes extend beyond the browser. In banking, insurance, and healthcare, a single workflow can involve several applications, operating environments, and legacy infrastructure.

Selenium can be extended with additional tools to cover parts of these processes, but the organisation must build and maintain the integrations. TestResults is designed for this broader environment, supporting automation across web, desktop, Citrix, mobile, and legacy applications.

The decision isn’t simply whether to use a free or commercial test automation tool. It’s whether the chosen approach can reliably test the business processes the organisation depends on.

If your existing Selenium framework covers those requirements, there may be little reason to replace it. But if critical workflows extend across multiple systems, it’s worth evaluating how much additional engineering effort your current approach requires.
