Lecture 2 - software testing SE 412.pptx

This document provides an overview of a course on Software Quality Assurance. It discusses several key points: - The course introduces students to Software Quality Assurance principles as practiced in industry. - Several methods are used for process and product assurance, including audits, inspections, reviews, testing, and assessments. - Embedded quality assurance activities aim to detect and remove errors early in the development cycle to reduce costs. - A case study of the Space Shuttle flight software project demonstrates how a rigorous quality assurance process using embedded activities achieved extremely high reliability.

This document provides an overview of software testing concepts. It discusses testing as an engineering activity and process. It introduces the Testing Maturity Model which describes stages of test process improvement. Basic definitions are provided for terms like error, fault, failure, test case, test oracle. Software testing principles and the tester's role are described. The origins and costs of defects are discussed. Defect classes are classified into requirements, design, code, and testing defects. The concept of a defect repository to catalog defect data is introduced. Examples of coin problem defects are given to illustrate defect classification.

The document discusses software testing terminology, principles, and phases. It defines errors, faults, failures, and their relationships. It also covers software quality metrics and attributes like correctness, reliability, and maintainability. Twelve principles of software testing are outlined around test planning, invalid/unexpected inputs, regression testing, and integrating testing into the development lifecycle. The phases of a software project are described as requirements gathering, planning, design, development, and testing.

This document provides an introduction to software quality assurance. It defines software as a set of instructions that guides the computer's hardware, and defines software quality assurance as planned actions to provide adequate confidence that software conforms to requirements. It discusses challenges to software quality like high complexity, invisibility of products, and limited opportunities to detect defects. Finally, it outlines important factors in managing software quality, like correctness, reliability, efficiency, and maintainability.

This document summarizes a lecture on software testing. It defines software testing and its objectives, including finding bugs, reducing risk, and ensuring requirements are met. Principles of testing discussed include that testing shows bugs but not their absence, exhaustion is impossible, and early testing is important. Factors that can lead to failures like pressures and complexity are reviewed. The document also discusses testing standards, the psychology of testing versus development, and careers in software testing.

the responsibilities and roles of the members of an organization during the software testing and development phase moreover, the test automation and its techniques with the need of doing test automation is discussed in the presentation

Static testing techniques like inspections, walkthroughs, and reviews check software products early in the development lifecycle without executing the code. Inspections are the most formal technique and involve individual review followed by a moderated team discussion. Walkthroughs are less formal than inspections. Reviews include management in addition to the technical team. Benefits of static testing include early bug detection and prevention, improved quality, and providing feedback to developers.

The document provides an overview of manual software testing, including definitions, goals, and best practices. It discusses the importance of testing, what should be tested, quality principles, standards and certifications, the software development life cycle, and roles in the testing process. Testing is defined as evaluating a system to verify requirements or identify differences between expected and actual results. It aims to deliver high quality software by finding errors prior to release. Quality, defined as meeting customer requirements, is crucial and improved through principles like defect prevention. The document outlines the software development process and life cycle from requirement analysis through maintenance.

Basic Testing Concepts. This Document will help you to learn the main theme of testing and how it works in our software field.

The document provides an introduction to software testing and test management. It discusses key concepts like quality, software testing definitions, why testing is important, who does testing, what needs to be tested, when testing is done, and testing standards. It also covers testing methodologies like black box and white box testing and different levels of testing like unit testing, integration testing, and system testing. The document is intended to give a basic overview of software testing and related topics.

Manual testing refers to testing software manually to identify bugs, where manual testers collaborate with developers to evaluate test scripts and resolve issues. Automated testing uses scripted testing tools to validate software functionality and requirements faster than manual testing. The document discusses the skills required for software testers, including knowledge of databases, Linux commands, test management and defect tracking tools, programming languages, analytical skills, and communication skills. It also outlines typical software tester career paths and roles at different experience levels.

This document provides an overview of defect management processes. It discusses defining defects, defect prevention, discovery, resolution and process improvement. The key aspects covered are: - Defining goals as preventing defects, early detection, minimizing impact and process improvement. - Activities like root cause analysis, escape analysis and process metrics. - The defect lifecycle of prevention, discovery, resolution and continuous improvement. - Examples of defect analysis and status reporting including metrics like density, backlog and mean time to repair.

This document discusses software inspections and walkthroughs. It defines them as processes for detecting defects in software artifacts. An inspection is a more formal process that collects metrics, while a walkthrough is more informal. The document outlines the typical steps of an inspection, including planning, overview, preparation, meeting, rework, and follow-up. It also discusses the roles involved, what can be inspected, and how inspection data can be used to improve the software development process and product quality.

The document provides an overview of software testing and quality assurance concepts. It defines key terms like software, software testing, quality assurance, and validation and verification. It describes the objectives and types of testing like static and dynamic analysis. It also discusses quality factors, metrics, statistical quality control methods like control charts, and total quality management approaches.

The document provides an overview of topics related to software quality assurance including software testing strategies, project management, risk management, and maintenance. It discusses software quality assurance and defines verification and validation. It describes different testing types like unit testing, integration testing, system testing, and validation testing. It also covers ISO standards for testing, SQA plans, testing goals and attributes. Finally, it discusses testing approaches, strategies for validation testing, and the goals of system testing.

Are you wondering how to migrate to the Cloud? At the ITB session, we addressed the challenge of managing multiple ColdFusion licenses and AWS EC2 instances. Discover how you can consolidate with just one EC2 instance capable of running over 50 apps using CommandBox ColdFusion. This solution supports both ColdFusion flavors and includes cb-websites, a GoLang binary for managing CommandBox websites.
