Delivering seamless digital experiences requires ensuring web and mobile applications perform flawlessly across diverse browsers, devices, and operating systems. However, comprehensively testing software functionality across this exponentially growing technology matrix presents challenges. Manual testing is too slow and narrow, given shortened release cycles. Coding automation frameworks from scratch demands extensive skills and time.

This article explores how modern functional automation testing tools now simplify cross-browser validation for both web and mobile apps. We will examine key considerations when evaluating options, from open source to commercial solutions.

By leveraging the right approach, teams can shift functional testing left, amplify coverage, accelerate feedback loops, and release higher-quality software regularly. Let’s explore how smarter tools allow organizations to keep pace with technology proliferation while delivering seamless experiences.

What Are Functional Testing Tools?

Functional testing tools are used to automate the process of checking if a system’s features and functions work as expected. Unlike tools for performance testing, usability testing, or stress testing, functional testing tools focus specifically on validating whether the system delivers its intended functional behaviors correctly.

The main purpose of functional testing is to take a particular requirement or acceptance criteria for a system feature and check whether that feature works consistently with what it is supposed to do. So, these tools allow testers to verify that critical system features behave as they should.

Points To Consider When Choosing Functional Testing Tools

Open-Source Tools

The pros of open-source tools are that they are completely customizable to fit your exact needs. You can build on top of popular test libraries like Selenium, Appium, and RestAssured. There is full control over test code, frameworks, and reporting. There are no licensing fees or costs except developer time.

The cons are that there is significant up-front development effort. Ongoing maintenance of the framework requires dedicated developers. Integrating related tools like test management and CI/CD adds complexity. There can be a lack of commercial support, leading to slower issue resolution.

Examples:  Selenium/Appium for web/mobile test automation, TestNG/JUnit for test runners, and Allure and ExtentReports for reporting.

Single-Purpose Commercial Tools

The pros of single-purpose commercial tools are that they have simple procurement, onboarding, and setup. There are pre-built automation capabilities for specific test types. Vendor documentation and support is available. Cloud-based tools have automatic upgrades.

The cons are that the narrow focus limits expand to other test types. Changing tools later means reworking existing assets. These tools require a per-user licensing model. The feature roadmap is driven by vendor priorities.

Examples: Selenium IDE for browser automation, Postman for API testing, and JMeter for performance testing.

Software Quality Management Platforms

The pros of software quality management platforms are that they provide unified test automation, management, and analytics. There are pre-built integrations between modules and dashboards for full visibility into testing. They offer flexible licensing to match growth and can leverage open-source tools underneath.

The cons are that the initial setup is more complex. There is potential for unused product capabilities. These platforms require some programming skills for advanced use cases and have a larger financial commitment upfront.

Examples: LambdaTest and Katalon Studio.

How To Choose Cross-Browser Testing Tools

When evaluating cross-browser testing tools, first clearly define the problem you aim to solve and the outcomes you hope to achieve. This will clarify must-have capabilities. Consider who requires access – more users means higher license costs. Factor in ease of use based on intended primary users.

Carefully review current testing tools and determine integration needs. Decide if a consolidated tool could replace multiple existing ones.

Align selection to current workflows and delivery methods. Don’t assume a popular tool fits your unique organization. Gauge what works versus causes issues.

Compare each option against these criteria:

• Problem statement and required features.
• License costs based on users.
• Integration with other test/automation/bug tools.
• Usability for testers or organizations.
• Adoption feasibility is given the culture.

Thoughtfully evaluating these points ensures the selected cross-browser testing tool matches both the present situation and future goals. Never forget that alignment to organization-specific needs and outcomes is vital for long-term value.

How Functional Testing is Done Using Tools

Modern functional testing tools empower teams to improve test coverage and accelerate release cycles through intelligent automation. By handling tedious tasks, they enable testers to focus on delivering quality at speed.

Several key features expedite function validation:

• Simplified Test Case Authoring:

Instead of complex coding, intuitive interfaces facilitate creating and adapting test scripts via keywords and low-code modules. Tests execute reusable steps reflecting real user workflows.

• Multi-Platform Execution:

Tests easily run across vast matrices of desktop and mobile browsers, operating systems, and devices for comprehensive coverage. Cloud infrastructure handles on-demand environment provisioning.

• Automated Test Data Management:

Tools centralize test data files and values for easy access and updating without breaking scripts. Randomization handles generating data variations to cover edge cases.

• AI-Powered Capabilities:

Smart assistants, computer vision, and machine learning take over repetitive tasks to amplify tester productivity. Self-healing locators, auto-suggestions, and diagnostics also boost efficiency.

• Continuous Integration:

Pipeline integration enables triggering automated test suites upon commits to provide instant feedback on functionality pre-release. Fast feedback facilitates fixing issues early.

• Consolidated Reporting & Analytics:

Centralized dashboards and visual analytics provide insights into test pass/failure rates, coverage, and cycle times for data-driven decisions.

By seamlessly integrating these capabilities into SDLC workflows, functional testing tools drive higher release velocity without compromising quality.
