Why Do You Need Software Testing?
Software testing might seem like a step you can skip — until you encounter a problem. Imagine you’re building a house. Would you skip inspecting the foundation just because it looks solid on the surface? Probably not. The same logic applies to software.
Bugs and glitches can creep into any stage of the development process. If left unchecked, they can lead to poor user experience, security vulnerabilities, costly fixes post-launch, and sometimes even disastrous events.
Here’s why software testing is an absolute must.
- Quality assurance: No one likes a shoddy product. Testing ensures that your software development meets its quality standards and delivers the value it promises. It’s the quality stamp that verifies your software is top-tier, giving you confidence in the final product.
- User satisfaction: Users have zero tolerance for poorly functioning apps. The digital world is competitive; a single crash can make users abandon your product for a competitor’s. Thorough testing guarantees that your software provides a seamless experience, which is essential for user retention.
- Cost efficiency: Detecting bugs during the developing phase is significantly more cost-effective than fixing them after the product is live. It’s a simple equation: The earlier you catch a bug, the less it costs to resolve.
- Security: With data breaches and cyber threats becoming increasingly common, security and penetration testing are more crucial than ever. Identifying and fixing vulnerabilities early can save your company from potential lawsuits, loss of reputation, and hefty fines.
With these factors in mind, let’s explore some expert software testing best practices to ensure your product is flawless when it reaches your users.
10 Software Testing Best Practices
So, how do you execute software testing in a way that is both efficient and effective?
- Start testing early

- Balance automated and manual testing
- Focus on user experience (UX) testing
- Utilize Dogfooding
- Implement regression testing regularly
- Prioritize testing types based on project requirements
- Perform continuous testing in CI/CD
- Utilize real devices and platforms
- Ensure consistent and clear documentation
1. Start Testing Early
The earlier you incorporate testing in your software testing life cycle (STLC), the better. Adopting a Shift Left testing approach means integrating testing activities early in the software development process. This proactive strategy helps in identifying issues before they become costly problems.
Start by establishing a clear testing plan. To ensure effective testing, clearly define the scope, the methods, and the criteria for success from the outset. Think of it as quality control from day one.
2. Incorporate Automated Testing
Automated testing saves time, especially when you’re running repetitive tests. Although initial setup may require time and resources, the long-term payoff is significant.
Jeremie Kweto, Founder & CEO of Ottawa Web Genius, claims that "Automated tools play a critical role in testing by streamlining repetitive, time-consuming tasks and enabling faster, more reliable testing processes."
According to Kweto, automated tools are particularly effective for regression testing, ensuring that existing features remain functional as new code is introduced. They can also handle load and performance testing by simulating high traffic volumes, helping verify that your application can handle real-world usage demands.
3. Balance Automated and Manual Testing
While automation is powerful, it’s not a one-size-fits-all solution. Manual testing is essential for exploratory scenarios, where testers can think creatively and identify unexpected bugs. Ramona Rohan, Head of QA at Wolfpack Digital, points out that “balancing automated and manual testing can be challenging, especially under tight deadlines and evolving requirements.”
She adds that creating accurate testing environments and keeping test suites updated — particularly for legacy systems — can be complex and time-consuming. The key to effective testing is a balanced approach: leveraging automation for repetitive tasks and regression testing while using manual testing to tackle complex, creative, or nuanced issues.
4. Focus on User Experience (UX) Testing
Your software might be feature-rich and technically sound, but if the user experience is clunky, users won’t stick around. UX testing ensures your product is intuitive, user-friendly, and aligned with user expectations.
Tools like Hotjar of Crazy Egg can provide valuable insights into user behavior. Real user feedback during testing can be a goldmine of information to guide improvements.
5. Utilize Dogfooding
Dogfooding means using your own software product as if you were a regular user before it’s officially launched. This practice involves your team experiencing the product firsthand to catch usability issues and bugs early on.
Andrii Bas, CEO of Sommo, explains, “The most effective and low-cost testing method is dogfooding. At this stage, your team is shaping the product concept, and dogfooding allows you to gather invaluable feedback from team members and initial users with diverse backgrounds, without needing extensive presentations or training.”
This method is particularly valuable for small, motivated teams, as it reveals both usability issues and unexpected bugs in real-world scenarios. As Bas points out, this hands-on experience not only refines the product but also prepares your team to better support and promote it.
6. Implement Regression Testing Regularly
Every time a new feature or update is introduced, there’s a risk that it could interfere with existing functionalities. Regular regression testing helps ensure that new additions don’t inadvertently disrupt what’s already working well. It acts as a safety net, catching any unintended side effects before they reach users.
By running regression tests consistently, you can maintain a stable, high-quality product while rolling out new features, keeping both your development team and users confident in the software’s reliability.
7. Prioritize Testing Types Based on Project Requirements
Not all software projects are the same, and neither are their testing needs. The type of testing you prioritize should align with the unique demands and objectives of the project. For instance, if you’re developing a game app, performance testing is essential to ensure smooth gameplay, quick response times, and scalability for handling multiple users at once.
On the other hand, if you’re working on a banking or financial application, security testing should take precedence to protect sensitive data, ensure compliance with regulations, and maintain user trust. By identifying which testing types are non-negotiable versus those that are nice-to-haves, your testing strategy becomes more resource-effective, aligning your QA efforts with the project’s goals.
8. Perform Continuous Testing in CI/CD
In continuous integration/continuous delivery (CI/CD) pipelines, integrating continuous testing can prevent issues from reaching production. Automated tests run each time code is committed, ensuring errors are quickly detected and resolved.
Bas emphasizes, “When CI/CD is properly set up with extensive test automation coverage, testers only need to focus on testing new features and writing tests specifically for them.” This means regression tests can run automatically and rapidly, freeing up valuable QA resources and significantly reducing the time needed before a release.
9. Utilize Real Devices and Platforms
While testing on emulators and simulators is useful during early development, it’s essential to perform final tests on real devices for accurate results. Emulators don’t always capture the subtle nuances of how your software interacts with actual hardware, networks, or sensors, which can lead to missed issues.
Testing on real devices helps identify discrepancies that might affect user experience, such as performance variations, connectivity issues, or device-specific bugs. This step ensures your software functions seamlessly in real-world conditions, delivering a consistent user experience.
10. Ensure Consistent and Clear Documentation
Testing documentation often takes a backseat, but it’s crucial for a smooth and efficient testing process. Clear, well-organized documentation provides teams with a comprehensive understanding of test cases, test environments, and results, enabling faster troubleshooting and streamlined workflows.
It also helps new team members get up to speed quickly, ensures continuity if testers change, and provides a reliable reference for future testing needs. In short, strong documentation builds a solid foundation for a cohesive testing strategy and promotes consistent, high-quality outcomes.
