The world of Software Development has changed significantly, especially in the post-COVID-19 era, with AI playing an essential role. Developers and QA teams increasingly rely on automation to improve efficiency. However, traditional QA methods like manual testing often fall short, leading to costly bugs, delayed releases, and poor user experiences.

The solution? Modern QA testing methodologies. These approaches improve software reliability and scalability. Let’s explore six key methodologies shaping the software development industry in 2025.

1. Manual Testing

Despite the growing popularity of automation, manual software testing is still essential in 2025. While automated tools are better at handling repetitive tasks and large datasets, they may struggle with subjective evaluations such as user experience, visual inconsistencies, and exploratory testing. This technique is necessary for:

Exploratory testing
Usability testing
Testing scenarios requiring human judgment

Key Benefits

Flexibility: Adapts to diverse testing scenarios.
Human Insights: Captures usability and UI/UX issues.
Low Setup Costs: Requires minimal tools and infrastructure.

Use Cases

Testing new features for user experience (UX) consistency.
Evaluating applications with dynamic content.

2. Automated Testing

QA automation will continue to dominate QA strategies in 2025. Automated testing uses powerful tools to handle repetitive tasks, ensuring comprehensive test coverage efficiently. Automated frameworks like the vStellar Test low-code automation framework simplify repetitive tasks, freeing QA teams to focus on more critical aspects.

Automation is particularly beneficial for CI/CD pipelines, where every code change is validated immediately. AI-powered automation tools help testers manage complex scenarios and self-correcting scripts.

According to Markets & Markets, automation testing is growing rapidly and is expected to reach a value of $55.2 billion by the end of 2028.

Key Benefits

Speed: Speeds up testing cycles.
Consistency: Delivers uniform test execution.
Scalability: Manages large datasets and environments.

Use Cases

Regression testing for frequent code changes.
Performance testing to handle high-traffic loads.

3. Performance Testing

In the age of instant gratification, Performance testing is no longer optional; it’s a necessity. Users want apps that work faster and more reliably. Performance testing evaluates an application’s speed, scalability, and stability under real-world conditions.

This methodology evaluates how an application performs under various conditions, such as high traffic or limited resources. 53% of mobile users abandon a site if it takes more than three seconds to load. This highlights the importance of this testing to ensure an application functions optimally. Performance testing also helps to identify potential blockages and areas of improvement.

With the vStellar Test performance testing feature, you can find and fix performance problems before they affect your users. vStellar Test gives your team real-time insights, smooth CI/CD integration, and reliable load simulations to help them perform stress testing for worst-case scenarios or scalability testing for future growth.

Types of Performance Testing

Load Testing: Assesses performance under expected loads.
Stress Testing: Tests the system's limits by overloading it.
Scalability Testing: Evaluates the system’s capacity to scale.
Spike Testing: Assesses performance during sudden traffic surges.

Key Benefits

Identifies performance bottlenecks.
Improves user satisfaction by ensuring optimal performance.
Reduces the risk of downtime during peak usage.

Use Cases

E-commerce platforms: Handling seasonal sales.
Streaming services: Managing global audiences.

4. Security Testing

Security testing has become essential due to the rise in cyberattacks. According to Cybercrime Magazine, the global costs of cybercrime are projected to rise by 15% annually, reaching $10.5 trillion annually in 2025, up from $3 trillion in 2015.

This methodology identifies vulnerabilities, ensures data protection, and complies with global security standards like GDPR and HIPAA. In 2025, QA teams use AI-powered tools to detect vulnerabilities more quickly. For example, automated security checks integrated into CI/CD pipelines can identify issues before they are deployed into production.

Key Techniques

Penetration Testing: Simulates attacks to uncover vulnerabilities.
Vulnerability Scanning: Detects known security flaws.
Threat Modeling: Analyzes potential threats and mitigation strategies.

Key Benefits

Protects sensitive user data.
Prevents financial and reputational losses.
Ensures compliance with security regulations.

Use Cases

Banking applications managing financial transactions.
Healthcare platforms storing patient records.

5. Agile Testing

Agile testing integrates QA processes into agile development frameworks. It emphasizes collaboration, continuous testing, and quick feedback loops. This approach ensures quality at every stage of the development lifecycle.

Key Principles

Continuous Testing: Tests are performed at each sprint.
Collaboration: QA and development teams work closely.
Adaptability: Quickly responds to changing requirements.

Key Benefits

Reduces time-to-market by identifying issues early.
Enhances communication between teams.
Improves overall product quality.

Use Cases

Mobile app development with rapid release cycles.
Startups adopting lean development methodologies.

6. AI-Driven Testing

As technology evolves in 2025, QA testing methodologies are also rapidly changing. Generative AI significantly impacts QA testing by making it easier to automate tests and predict system bugs.

Analyze patterns.
Review large volumes of test data.
Predict potential failures.
Create intelligent test scenarios.
Optimize test coverage.
Prioritize critical test cases.
Generate scripts autonomously.
Improve the efficiency and accuracy of QA processes.

Key Features

Self-Healing Scripts: Automatically adapt to UI changes.
Predictive Analytics: Anticipates defects before they occur.
Test Optimization: Identifies redundant test cases and prioritizes critical ones.

Key Benefits

Reduces manual effort through intelligent automation.
Improves defect detection rates.
Enables faster decision-making with real-time insights.

Use Cases

Large-scale enterprise applications with complex systems.
Continuous testing within CI/CD pipelines.
Visual testing to ensure UI consistency across devices.
