Writing Quality Software
Writing Quality Software About this white paper: This whitepaper was written by David C. Young, an employee of General Dynamics Information Technology (GDIT). Dr. Young is part of a team of GDIT employees who maintain, and support high performance computing systems at the Alabama Supercomputer Center (ASC). This was written in 2020. This paper is written for people who want to write good software, but don’t have a master’s degree in software architecture (or someone managing the project who does). Much of what is here would be covered in a software development practices class, often taught at the master’s degree level. Writing quality software is not only about the satisfaction of a job well done. It is also reflects on you and your professional reputation amongst your peers. In some cases writing quality software can be a factor in getting a job, losing a job, or even life or death. Furthermore, writing quality software should be considered an implicit requirement in every software development project. If the intended useful life of the software is many years, that is yet another reason to do a good job writing it. Introduction Consider this situation, which is all too common. You have written a really neat piece of software. You put it out on github, then tell your colleagues about it. Soon you are bombarded with a series of complaints from people who tried to install, and use your software. Some of those complaints might be; • It won’t install on their version of Linux. • They did the same thing you reported, but got a different answer. -

Types of Software Testing
Types of Software Testing We would be glad to have feedback from you. Drop us a line, whether it is a comment, a question, a work proposition or just a hello. You can use either the form below or the contact details on the rightt. Contact details [email protected] +91 811 386 5000 1 Software testing is the way of assessing a software product to distinguish contrasts between given information and expected result. Additionally, to evaluate the characteristic of a product. The testing process evaluates the quality of the software. You know what testing does. No need to explain further. But, are you aware of types of testing. It’s indeed a sea. But before we get to the types, let’s have a look at the standards that needs to be maintained. Standards of Testing The entire test should meet the user prerequisites. Exhaustive testing isn’t conceivable. As we require the ideal quantity of testing in view of the risk evaluation of the application. The entire test to be directed ought to be arranged before executing it. It follows 80/20 rule which expresses that 80% of defects originates from 20% of program parts. Start testing with little parts and extend it to broad components. Software testers know about the different sorts of Software Testing. In this article, we have incorporated majorly all types of software testing which testers, developers, and QA reams more often use in their everyday testing life. Let’s understand them!!! Black box Testing The black box testing is a category of strategy that disregards the interior component of the framework and spotlights on the output created against any input and performance of the system. -

Testing Guide 4Deets
TESTING GUIDE Automated Testing for SuccessFactors Introduction This guide will give you an overview of the different aspects of testing your SuccessFactors environment. As most employees interact in some way or form with the system, it’s crucial to test your system regularly and around crucial events to make sure you provide an excellent employee experience. The following topics will be explored: • Testing During An Implementation • Testing For Configuration Changes • Testing For Quarterly Releases • Manual vs. Automated Testing © 2019 Page | 2 Automated Testing For SuccessFactors Testing During An Implementation During an implementation, testing is critical to make sure the system is designed and configured according to expectations. One of the most known test is User Acceptance Testing (UAT) in which a client signs off that the system works as expected. Before UAT, there are many different tests you would like to perform. These tests are done during different phases of a project. Some only once, others multiple times. Let’s start with looking at what phases there are during a SuccessFactors implementation. This may differ slightly, but all SuccessFactors implementations basically follow the same path. The reason for this is that the Agile methodology, which is the preferred method defined by SAP, needs to be followed by SAP professional services and all the certified implementation partners. This methodology has been proven to be most successful. The Agile methodology is an iterative approach. Iterative approach is a way of breaking down the system development of a large application into smaller chunks. In iterative development, functionality is designed, configured and tested in repeated cycles. -
Leading Practice: Test Strategy and Approach in Agile Projects
CA SERVICES | LEADING PRACTICE Leading Practice: Test Strategy and Approach in Agile Projects Abstract This document provides best practices on how to strategize testing CA Project and Portfolio Management (CA PPM) in an agile project. The document does not include specific test cases; the list of test cases and steps for each test case are provided in a separate document. This document should be used by the agile project team that is planning the testing activities, and by end users who perform user acceptance testing (UAT). Concepts Concept Description Test Approach Defines testing strategy, roles and responsibilities of various team members, and test types. Testing Environments Outlines which testing is carried out in which environment. Testing Automation and Tools Addresses test management and automation tools required for test execution. Risk Analysis Defines the approach for risk identification and plans to mitigate risks as well as a contingency plan. Test Planning and Execution Defines the approach to plan the test cases, test scripts, and execution. Review and Approval Lists individuals who should review, approve and sign off on test results. Test Approach The test approach defines testing strategy, roles and responsibilities of various team members, and the test types. The first step is to define the testing strategy. It should describe how and when the testing will be conducted, who will do the testing, the type of testing being conducted, features being tested, environment(s) where the testing takes place, what testing tools are used, and how are defects tracked and managed. The testing strategy should be prepared by the agile core team. -

Functional Testing Functional Testing
From Pressman, “Software Engineering – a practitionerʼs approach”, Chapter 14 and Pezze + Young, “Software Testing and Analysis”, Chapters 10-11 Today, weʼll talk about testing – how to test software. The question is: How do we design tests? And weʼll start with Functional Testing functional testing. Software Engineering Andreas Zeller • Saarland University 1 Functional testing is also called “black- box” testing, because we see the program as a black box – that is, we ignore how it is being written 2 in contrast to structural or “white-box” testing, where the program is the base. 3 If the program is not the base, then what is? Simple: itʼs the specification. 4 If the program is not the base, then what is? Simple: itʼs the specification. Testing Tactics Functional Structural “black box” “white box” • Tests based on spec • Tests based on code • Test covers as much • Test covers as much specified behavior implemented behavior as possible as possible 5 Why Functional? Functional Structural “black box” “white box” • Program code not necessary • Early functional test design has benefits reveals spec problems • assesses testability • gives additional explanation of spec • may even serve as spec, as in XP 6 Structural testing can not detect that some required feature is missing in the code Why Functional? Functional testing applies at all granularity levels (in contrast to structural testing, which only applies to Functional Structural unit and integration testing) “black box” “white box” • Best for missing logic defects Common problem: Some program logic was simply forgotten Structural testing would not focus on code that is not there • Applies at all granularity levels unit tests • integration tests • system tests • regression tests 7 2,510,588,971 years, 32 days, and 20 hours to be precise. -
