Software Testing Bootcamp | Types of Testing | Verification, Validation | Software Testing Tutorials

Summary

This tutorial delves into the basics of software testing, focusing on the two primary types: static and dynamic testing. It clarifies the differences between these types, emphasizing that static testing involves reviewing documents without code execution, while dynamic testing requires interacting with and running the code. The video also explains the concepts of verification (ensuring the product is built correctly) and validation (ensuring the product meets customer needs). The presenter sets the stage for future lessons on why testing is crucial and addresses common industry questions.

Takeaways

• 💻 Static testing focuses on reviewing work products like documentation, requirements, and designs without executing code.
• 🛠️ Dynamic testing involves executing the code and interacting with the actual product to validate its functionality.
• 📂 Static testing is often referred to as verification, which ensures the product is being built correctly through non-executable methods.
• ⚙️ Dynamic testing, also called validation, ensures the right product is being built, focusing on the actual customer requirements.
• 📊 Static testing methods include reviews, walkthroughs, and inspections, while dynamic testing uses white-box, black-box, functional, and non-functional testing.
• 🧪 Static testing can detect defects early in the development process, such as during requirements or design phases, which is more cost-effective.
• 🚀 Dynamic testing happens after static testing and identifies bugs by interacting with the system during its execution.
• 🛠️ Levels of dynamic testing include unit testing, integration testing, system testing, and acceptance testing.
• ✅ Verification checks if the product conforms to specifications, while validation ensures the product meets the customer’s needs.
• 🛡️ Both static and dynamic testing are crucial, with static testing preventing early defects and dynamic testing ensuring the final product functions as expected.

Q & A

What are the two main types of testing discussed in the video?

The two main types of testing are static testing and dynamic testing.

How is static testing different from dynamic testing?

Static testing is non-executable and focuses on reviewing documents and work products without running code. Dynamic testing, on the other hand, involves executing code and interacting with the software to validate functionalities.

Can you provide examples of work products involved in static testing?

Examples of work products include requirements, design documents, business models, UML diagrams, test cases, and test plans.

What are some methods used in static testing?

Static testing methods include reviews, walkthroughs, technical reviews, and inspections.

What is dynamic testing and when is it performed?

Dynamic testing involves running the code or application and testing its functionality. It is performed after static testing and occurs at different levels, such as unit, integration, system, and acceptance testing.

How are verification and validation related to static and dynamic testing?

Verification is associated with static testing and focuses on ensuring that the work products meet specified requirements without executing code. Validation, linked with dynamic testing, ensures that the final product meets the customer's expectations by executing the software.

What is the difference between verification and validation in simple terms?

Verification checks if the product is built right, meaning it meets the requirements correctly. Validation checks if the right product is built, meaning it fulfills the customer's needs and expectations.

What is an example illustrating the difference between verification and validation?

An example is when a customer asks for an iPhone but is shown a Samsung phone. While the Samsung phone is a working product (verification passed), it is not what the customer requested (validation failed).

What are some benefits of static testing in the early stages of software development?

Static testing helps identify defects early in the development process, such as in design or requirement phases, which makes fixing these defects cheaper and more efficient.

Why is dynamic testing essential even after static testing?

Dynamic testing identifies defects that static testing cannot catch, as it involves actual execution of the software to check for issues that arise when the code is run.
