Software Quality and Testing

Simple Smalltalk Testing: With Patterns : Using PyCharm with Pyunit and pytest : I used the oficial Pycharm website example, as recommended from some classmates. Pycharm Example It has a really good guide on how to do a Pytest . I liked the LinkedIn course on TDD for python but is not that good explained. I would've liked more interaction from the from the instructor. WayBackMachine site : I searched for Amazon, and this screenshot ir from 1998.

Disjoint: blocks should not overlap 2. What is an Input Domain Model (IDM)? Two Approaches to Input Domain Modeling: A. Interface-based approach. 􏰀 Develop characteristics directly from individual input parameters. 􏰀 Just use properties of the domains without considering the actual function under test. B. Functionality-based approach 􏰀 Develop characteristics from a behavioral view of the program under test. 􏰀 Use your understanding of what the system should do. 3. What gives more tests, each choice coverage or pair-wise coverage? Each Choice Coverage (ECC) states that one value from each block for each characteristic must be used in at least one test case. For example, for partitions [A, B] [1, 2] we can get [A, A], [B, B], [1, 1] and [2, 2] which are clearly redundant. Pair-

Exam 1 Software quality and testing 1. Define each of: Software fault: static error in the code. Software error: internal, not a normal behavior of the program due to a fault. Software failure: external, visible failure of the program. That it doesn't work basically. 2. List 5 levels of test process maturity.  Level 0: Testing and debugging are the same. (Worst level) Level 1: Testing is only to find that your code doesn't work. Level 2: Get defensive or make an issue personal with testers because they broke your code. Level 3: Understand the job of a tester and take feedback as constructive criticism. Level 4: Become an expert software tester and make extreme good quality software. Work in harmony with testers. 3. Explain difference between revenue tasks and excise tasks. Revenue tasks contribute directly to the solution of a problem, and excise tasks do not. Excise tasks are candidates for automation, revenue tasks are not. 4. Authors, History

Credits to @chesteralvarez Image Link What is DevOps? Is the blending of the roles of developers and operations support.  Example: In application service, developers write the code that is deployed* into application service. Operations team maintains the application server. If the application fails to work on deployment there is a knowledge gap. People with knowledge of both software development and operations are required to bridge this gap, this is where DevOps practitioners are required. deployed*: Software deployment includes all the process required for preparing a software application to run and operate in a specific environment. It involves installation, configuration, testing and making changes to optimize the performance of the software. It can either be carried out manually or through automated systems. How it is important to the software engineering process? The software development lifecycle is complex and has a number of important phases which include: Re
