Glass Box testing - Answer-A method of software testing which tests the code and internal program structure of software. Functional testing - Answer-A type of software testing that verifies the functionality of a software system or application. Focuses on ensuring the system behaves according to the functional requirements. Unit testing - Answer-A testing method which individual units of source code are tested to determine whether they are fit for use. Define coupling - Answer-The degree of interaction between two modules List the five categories (levels) of coupling - Answer-5. Data coupling (good) 4. Stamp coupling 3. Control coupling 2. Common coupling 1. Content coupling (bad) Define cohesion - Answer-The degree of interaction within a module List the seven categories (levels) of cohesion - Answer-7. Informational cohesion (good) 6. Functional cohesion 5. Communicational cohesion 4. Procedural cohesion 3. Temporal cohesion 2. Logical cohesion 1. Coincidental cohesion (bad)What is portability? - Answer-Refers to the ability of an application to operate on different devices or software platforms Give at least two methods of portability. - Answer-1. Use a popular programming language 2. Use a popular operating system 3. Adhere strictly to language standards 4. Avoid numerical incompatibilities 5. Document meticulously Strengths of design patterns - Answer-Design patterns promote reuse by solving a general design problem. Design patterns provide high-level design documentation, because patterns specify design abstractions. Weaknesses of design patterns - Answer-The use of 23 standard design patterns may be an indication that the language we are using is not powerful enough. There is as yet no systematic way to determine when and how to apply design patterns. Four principles that make a good programming language. - Answer-Encapsulation Data abstraction Polymorphism Inheritance Give 4 solutions to make your code more readable. - Answer-1) Use consistent and meaningful variable names. 2) Use indentation 3) Use blank lines to break up big blocks of code. 4) Leave clear comments when a code is written in a non-obvious way. Disadvantages of Object Oriented Programming (OOP) - Answer-OOP has a steep learning curve, a larger programming size, slower programs, and is not suitable for all types of problems.
