CH02. L02. Test-types
Summary
TLDRThis script delves into the multifaceted world of software testing, highlighting the importance of identifying testing objectives to select the appropriate testing type. It outlines four key types: Functional testing, which is 'Black box testing' ensuring software meets requirements; Non-functional testing, measuring performance and usability; Structural testing, the 'White box testing' focusing on internal logic; and Testing Related to Changes, including 'Confirmation Testing' and 'Regression Testing' to ensure bug fixes don't impact other modules. The script emphasizes assessing customer needs, security, interoperability, and the software's ability to handle load and maintain reliability.
Takeaways
- 🔍 The testing process is divided into activities with varying objectives, from testing individual software components to the entire software system.
- 📝 Identifying the testing objective is crucial to determine the appropriate type of testing to be conducted.
- 🛠️ There are four main types of testing: Functional, Non-functional, Structural, and Testing Related to Changes.
- 📊 Functional testing, often called 'Black box testing', focuses on the software's external behavior and whether it meets the specified requirements.
- 🔒 Security testing within functional testing checks for vulnerabilities that could be exploited by hackers, protecting data and information.
- 🔄 Interoperability testing ensures that the software can interact with different components and systems outside of itself.
- 📐 Suitability testing assesses if the software's functionality aligns with the business needs as per the requirements.
- 🔢 Accurateness testing verifies that the software's output matches the expected results.
- ⚙️ Non-functional testing evaluates 'How the system works?' by measuring characteristics like performance, load, stress, usability, maintainability, reliability, and portability.
- 👷♂️ Structural testing, known as 'White box testing', examines the internal logic of the software's source code to ensure correctness.
- 🔄 Confirmation Testing is conducted after developers fix bugs to ensure the issue has been resolved, followed by Regression Testing to check for any new issues caused by the fix.
Q & A
What are the main objectives of the testing process?
-The main objectives of the testing process vary from testing a specific part of the software to testing the entire software, ultimately to ensure that the software meets its intended requirements and functions correctly.
What is Functional Testing and what does it focus on?
-Functional Testing is a type of testing that focuses on testing all the software functionalities that were previously identified in the requirements. It answers the question 'what the system does?' and ensures that the software behaves as specified in the requirements.
How does Functional Testing relate to the calculator program example mentioned in the script?
-In the calculator program example, Functional Testing would help to test whether the calculator accepts user input, performs the addition correctly, and provides the correct result. It ensures that the software meets the specified requirements for functionality.
What are the different types of Functional Testing mentioned in the script?
-The script mentions four types of Functional Testing: Security Testing, Interoperability Testing, Suitability Testing, and Accurateness Testing. Each type focuses on different aspects such as security vulnerabilities, compatibility with other systems, adherence to requirements, and correctness of results.
Why is it important to consider all testing levels for Functional Testing?
-It is important to consider all testing levels (Unit, Integration, System) for Functional Testing because it ensures that the software's external behavior is tested consistently at each stage of development, helping to catch and fix issues early in the process.
What is the difference between Black Box Testing and White Box Testing?
-Black Box Testing, also known as Functional Testing, focuses on the software's external behavior without considering the internal structure. It tests the software based on its specifications. White Box Testing, on the other hand, focuses on the internal structure and logic of the software, examining the source code to ensure it works correctly.
What does Non-functional Testing measure in software?
-Non-functional Testing measures the software's characteristics such as performance, load, stress, usability, maintainability, reliability, and portability. It answers the question 'How does the system work?' and ensures that the software operates efficiently under various conditions.
How does the script define Suitability Testing?
-Suitability Testing is a type of Functional Testing that assesses whether the software's functionality was designed according to the requirements. It checks if the software can perform the tasks it was intended to do, such as accepting user input in the calculator example.
What is the purpose of Confirmation Testing and Regression Testing?
-Confirmation Testing is conducted to ensure that a bug has been fixed after the developer's intervention. Regression Testing follows to check that the fix has not introduced new issues or affected other parts of the software, ensuring that the changes do not negatively impact previously tested modules.
How does the script describe the importance of assessing customer needs in testing?
-The script emphasizes that one of the key aspects of testing is to assess whether the customer's needs have been fulfilled and succeeded. This involves checking that the software meets the business and technical requirements specified by the customer.
