ISTQB Foundation Level #3 - What is Software Testing

Summary

This session introduces the fundamentals of software testing as per ISTQB Foundation Level. Using real-world examples like electronic devices, it explains that testing ensures products function correctly before reaching users. The video highlights that software testing is a continuous process throughout the software development lifecycle, encompassing static testing (document reviews, inspections) and dynamic testing (unit, integration, system, and acceptance tests). Key objectives include verifying that software meets user requirements, is fit for use, and identifying defects early to improve quality. Additionally, test planning, preparation, execution, and evaluation are emphasized as essential steps for delivering reliable, high-quality software.

Takeaways

• 😀 Software testing is a process that spans the entire software development lifecycle and is not a standalone activity.
• 😀 Both static and dynamic testing are essential: static testing involves document reviews, while dynamic testing validates the working software build.
• 😀 Test planning is critical and includes defining objectives, assigning responsibilities, setting timelines, and monitoring progress.
• 😀 Test preparation involves creating test cases, scenarios, test data, and setting up the test environment.
• 😀 Evaluation during testing ensures that exit criteria are met, such as achieving a required pass rate of test cases.
• 😀 Software testing includes verifying not just the executable code but also related work products like user guides, installation guides, and design documents.
• 😀 One of the main objectives of software testing is to confirm that the software meets end-user and stakeholder requirements.
• 😀 Testing ensures that the software is fit for use and performs as expected in real-world scenarios.
• 😀 Finding defects early in requirements, design, or software code improves overall software quality and reduces potential production issues.
• 😀 Root cause analysis of defects identified during testing helps improve the software development process and prevents similar defects in the future.
• 😀 Software testing helps stakeholders make informed release decisions by validating software against specifications and usability requirements.

Q & A

What is software testing and why is it important?

Software testing is a process that involves evaluating software and related work products to ensure they meet customer requirements and are fit for use. It is important because it identifies defects early, improves software quality, and ensures the software performs correctly for end-users.

How does software testing compare to testing in the manufacturing of electronic devices?

Similar to electronic devices like TVs or automobiles, which are tested both as individual components and as a complete product before reaching consumers, software testing involves testing individual units (unit testing) and integrated software systems (system testing) to ensure quality and functionality.

What are the main objectives of software testing according to ISTQB?

The main objectives are: 1) to ensure the software meets end-user requirements, 2) to demonstrate that the software is fit for use, 3) to find defects or bugs in advance, and 4) to improve the software development process through root cause analysis.

What is the difference between static and dynamic testing?

Static testing involves reviewing documents, code, and design artifacts without executing the software, using techniques like inspections and walkthroughs. Dynamic testing involves executing the software to validate its functionality, using techniques such as unit, integration, system, and acceptance testing.

What role does planning play in software testing?

Planning is crucial as it defines the objectives, scope, responsibilities, schedule, and metrics for testing. It ensures that testing is organized, resources are allocated efficiently, and progress can be monitored effectively.

What is meant by test preparation in software testing?

Test preparation involves creating test cases and scenarios, setting up the test environment, preparing necessary test data, and ensuring all related documents and requirements are ready for execution.

What are exit criteria in software testing?

Exit criteria are predefined standards or conditions that determine when testing can be concluded. For example, an exit criterion might require that at least 90% of test cases pass before considering the software ready for release.

What kinds of work products besides the software itself are tested?

In addition to the software code or executable, testing also covers related work products such as user guides, installation guides, training materials, design documents (HLD, LLD), and requirement specifications to ensure overall quality.

How does software testing improve the software development process?

Through root cause analysis of defects found during testing, teams can identify why defects occurred and adjust development practices to prevent similar issues in future projects, thereby improving the overall development process.

How do testers ensure that software is fit for use?

Testers validate that the software performs as expected by end-users, meets functional and non-functional requirements, and operates reliably in the intended environment, ensuring it is suitable and effective for its intended purpose.

Why is software testing considered a process rather than a standalone activity?

Because it spans the entire software development life cycle, involving planning, static and dynamic testing, preparation, execution, evaluation, and assessment of both software and related documentation. It is continuous and systematic rather than isolated.
