Software Testing Tutorial #16 - Types of Software Testing

Summary

This tutorial discusses the different types of software testing, distinguishing between functional and non-functional testing. Functional testing focuses on verifying specific functionalities, like registration or adding items to a cart, while non-functional testing assesses aspects such as performance and response time. The video explains various types of functional tests, including unit, integration, and regression testing, as well as non-functional tests like load and security testing. The goal is to help viewers understand the broad categories and essential types of testing used in software projects.

Takeaways

• 🧑‍💻 Software testing is categorized into levels and types, and the two concepts are different.
• 🔍 There are many types of software testing, which can generally be grouped into functional and non-functional categories.
• 💡 Functional testing focuses on verifying the functionality of the software according to customer requirements, such as registration, adding items to the cart, or checkout.
• ⏱️ Non-functional testing, like performance testing, assesses aspects like the response time of a system, such as how long it takes to register a user on an e-commerce website.
• 🛠️ Examples of functional testing include unit testing, integration testing, system testing, and acceptance testing.
• 🔥 Non-functional testing includes performance testing, load testing, stress testing, security testing, and more.
• 🛡️ Security testing ensures that the software is protected from hackers and data breaches.
• ⚙️ Functional tests validate the process (e.g., registering successfully), while non-functional tests evaluate how efficiently the process occurs (e.g., time taken for registration).
• 📊 Load, stress, volume, and scalability testing fall under the broader umbrella of performance testing.
• 📚 While there are many types of testing, the most common ones are typically covered in software testing projects, and it's useful to research the less common types for interview preparation.

Q & A

What are the four levels of software testing mentioned in the previous tutorial?

The four levels of software testing mentioned in the previous tutorial are not explicitly stated in the provided script, but they typically include Unit, Integration, System, and Acceptance testing.

How does the script differentiate between levels of testing and types of testing?

The script differentiates between levels of testing and types of testing by stating that levels of testing refer to the hierarchy or stages at which testing is performed (e.g., unit, integration, system, acceptance), whereas types of testing refer to the various methods or categories of testing performed within a project, such as functional or non-functional testing.

What is the primary focus of functional testing?

Functional testing focuses on the testing of the functionality of a particular software. It involves verifying that the software meets the functional requirements provided by the customer, such as the registration functionality on an e-commerce website.

Can you provide an example of a functional requirement for an e-commerce website?

An example of a functional requirement for an e-commerce website is the ability for users to register on the site, which involves providing details like first name, last name, email, and other necessary information, and then clicking on a 'register' button to complete the registration process.

What is non-functional testing, and how does it differ from functional testing?

Non-functional testing evaluates the non-functional aspects of a software application, such as performance, security, and usability. It differs from functional testing in that it is concerned with how the software performs under various conditions rather than whether it performs the correct functions.

How is response time related to non-functional testing?

Response time is related to non-functional testing as it measures how quickly the system responds to user actions, such as clicking a 'register' button. Non-functional testing includes evaluating the system's performance, which can involve checking response times to ensure they meet the expected standards.

What are some examples of non-functional testing types mentioned in the script?

Some examples of non-functional testing types mentioned in the script include performance testing, load testing, stress testing, volume testing, scalability testing, recovery testing, and security testing.

Why is security testing important in software testing?

Security testing is important in software testing to ensure that the software is secure from potential hacking attempts and unauthorized access, thereby protecting user data and maintaining the integrity of the application.

What is the purpose of regression testing, and will it be covered in a separate tutorial?

Regression testing is the process of verifying that software modifications have not adversely affected existing features. The script indicates that regression testing will be covered in a complete separate tutorial.

What is the difference between functional and non-functional aspects of testing the registration feature on an e-commerce website?

The functional aspect of testing the registration feature would involve ensuring that the registration process works correctly by providing the necessary details and clicking the 'register' button. The non-functional aspect would involve testing how the website performs during registration, such as measuring the response time it takes to register and redirect the user to the dashboard.

What is the significance of the script's statement that some types of testing are more interview-focused rather than commonly used in projects?

The script suggests that while there are many types of testing that can be found through a Google search, not all of them are commonly used in actual software testing projects. Some types of testing are more likely to be encountered in interviews as a way to assess a candidate's knowledge rather than being practical tools used regularly in the industry.
