Overview of Mercury Automated Testing
In recent years, automated testing has seen significant growth, largely driven by tools from companies like Mercury Interactive, IBM Rational, and Segue. These advancements have positioned automated testing as a central component in many major organizations, especially with methodologies like eXtreme Programming emphasizing automation.
Why Automate Testing?
Automated testing offers several key advantages:
Speed
Automated tests run significantly faster than manual ones, allowing more tests to be completed in a shorter time. It's not uncommon for regression suites that take two weeks manually to be reduced to just 24 hours with automation tools.
Consistency and Repeatability
Automated tests ensure consistency as they perform the same actions exactly as recorded. Unlike manual testing, there's no risk of human error or variation across repeated tests.
Cost Efficiency
Once established, automated tests can run unattended, such as overnight, reducing resource requirements and costs.
Comprehensive Audit Trail
Automated scripts and test results are meticulously stored, providing a complete audit trail of all testing activities conducted.
Enhanced Test Coverage
As test packs grow, more tests can be included. With faster execution times and less resource demand, broader testing can be achieved, ensuring greater coverage of the application.
Freeing Up Testers
With structured testing automated, testers can focus on other important areas like accessibility, usability, and ad-hoc testing, which are often overlooked.
Automation-only Testing
Certain scenarios, like simulating 5000 concurrent users on a website, are only feasible through automation.
Types of Automated Testing Tools
1. Functional/Regression Tools
- These tools record user interactions with applications and allow tests to be data-driven. Advanced options like Mercury's WinRunner or QuickTest Professional offer robust development environments to manipulate applications thoroughly.
2. Load/Performance Tools
- Designed to emulate concurrent users performing tasks, these tools answer questions about application support capacity, performance under load, and potential bottlenecks. Mercury’s LoadRunner is an example.
3. Test Management Tools
- Solutions like Mercury’s TestDirector or Quality Center provide centralized management of test requirements, scripts, execution results, and defect tracking, integrating seamlessly with automated tools.
Challenges and Solutions in Test Automation
While automation tools offer great benefits, they can become underutilized if their complexity isn't managed. Here are some solutions to maximize their effectiveness:
- Technical Skills
- Ensure testers have a solid understanding of technology and programming experience.
- Comprehensive Training
- Invest in thorough training programs. Experienced trainers can demonstrate tool usage and highlight common pitfalls.
- Initial Hand-Holding
- Consider hiring consultants to establish the automated infrastructure and provide on-site training. Their expertise can accelerate the setup process, saving time and effort.
Conclusion
Tools like LoadRunner, WinRunner, QuickTest Pro, TestDirector, and Quality Center can offer substantial returns on investment. However, initial training and support are crucial for unlocking their full potential and maximizing effectiveness.
