Iterative software development
Iterative software development involves breaking projects into short iterations where cross-functional teams work to develop and test incremental releases. Each iteration results in a stable, integrated release. Core activities within each iteration include requirements gathering, analysis, design, development, testing, and deployment. This allows continuous integration and feedback between developers, customers, and management.
Mt s6 sdlc_models
The document discusses various software development life cycle (SDLC) models. It explains that SDLC models describe how development activities will be carried out to implement software. The models are categorized as sequential models and iterative models. Sequential models involve carrying out all activities sequentially for the entire application, while iterative models divide projects into modules and carry out activities per module. Specific sequential models discussed are waterfall and V-model, while iterative models include RAD, spiral, prototype, and agile-scrum models. The document provides details on the processes, advantages, and disadvantages of each model.
product Qa workflow
The document discusses different views of testing in agile environments, challenges that agile principles pose for testing, and how QA works with agile development teams. It describes extreme and exploratory testing approaches, contradictions between traditional and agile testing principles, and practices like test-driven development and maintaining a releasable product increment. The workflow involves developers writing unit tests, continuous integration, and QA maintaining test cases and running regressions after releases to assure quality.
Structured Qa
This document outlines the software testing process which includes evaluating resource requirements, building use cases and test plans, authoring test scripts, executing tests, filing and retesting defects, and evaluating quality goals. The process involves multiple phases from design to deployment including unit testing, integration testing, interface testing, regression testing, and production deployment checks.
Navyug Process Flow QA
The document outlines the Navyug Testing Process which includes requirements analysis, static testing, test planning and dynamic testing. Requirements are analyzed for defects and gaps. Static testing involves functional and non-functional testing. Dynamic testing then executes the test cases developed during planning and includes both manual and automated testing of functionality and non-functional areas like performance and security. Issues are logged, tracked to resolution and reporting finalizes the testing process.
Branching and Merging Practices
This document discusses different branching and merging practices for managing code in source control. It describes branch by release patterns where different branches are maintained for each release. It also covers branch by quality where branches are used to isolate different code quality stages. Branch by feature is presented as another option where branches are used to isolate development of independent features. The document provides examples and considerations for selecting the appropriate branching strategy based on factors like project needs and timelines.
Iterative model
The iterative model breaks a project into small modules that can be delivered incrementally. A working version is produced in the first module, with each subsequent release adding additional functionality until the full system is complete. It allows for quick releases during development and makes it easier to develop and test in smaller iterations while incorporating customer feedback at each stage. However, it requires more resources than traditional models and skilled management to avoid increased costs over time.
SCM Process and smartBuild
This document provides an overview of build and release management for software development projects. It discusses how build and release management is an important part of software configuration management. An often overlooked task is getting software from developers to testers, which requires coordinating who delivers components and what is included in each build. Large projects rely on frequent iterations of building, testing, debugging, and coding. The document recommends implementing build system automation using tools like Cruise Control or Bamboo for continuous integration. It also suggests integrating code coverage tools and preparing flexible build environments to achieve end-to-end automation.

Feature Driven Development
Feature driven development is an iterative software development process where work is organized around features that provide business value to users. It involves programmers, testers, and users collaborating to define features, write test cases, develop code in iterations, and conduct reviews and testing to ensure features meet specifications. The goal is to develop features that pass completeness and correctness tests meeting quality criteria before being deemed ready for release.
Branching and Merging and Bears, Oh My!
Team Foundation Server (TFS) provides a robust, enterprise-grade version control system. But how you use that system will determine your level of success. Much has been written about the 'right way' to branch and merge your code. But the fact is, there is no one single best way. This Webinar will discuss the common patterns used for branching and merging code and, more importantly, why to adopt one. We'll talk through aggregate branching models, trade-offs for release management and development, and how to evolve your existing code into the right branching model. Join us for this session and learn how to define the right branching and merging strategy for your team!
Version control Flow
This document outlines the version control process using branching and tagging. Developers create branches off the master version to work on features independently and merge them back after testing. The master version is then updated and tagged to release the application, with automated builds, tests, and code reviews at each step. Separate versions are maintained through branching for concurrent development and tagging for releases.
CIPL Application Development Process
The document describes the development process used by Classic Informatics Private Limited which includes defining requirements, planning and designing, application development, testing, debugging, and deployment. Key aspects of the process are prototyping, modular releases, periodic client updates, checklists, a defined architecture, common libraries, knowledge management, and task/bug tracking. A separate section outlines the quality control process which involves quality planning, testing according to test plans and cases, fixing bugs, and regression testing until all issues are closed.
How to organize qa process in agile speed
This document discusses organizing QA processes within an Agile Scrum team. It describes the project structure, team structure, and work processes of a distributed Scrum team supporting newspaper sites. Key QA activities in Scrum include negotiating quality, clarifying stories/tasks, ensuring acceptance tests verify quality, and providing estimates. Some challenges faced include frequent releases, lack of demos with business, communication issues, insufficient task descriptions, and not tracking QA work in sprints. Suggested solutions involve improving processes around releases, demos, communication, knowledge sharing, task descriptions, adding QA estimates to sprints, and breaking large tasks into smaller ones.
Automated testing overview
Automated testing overview discusses the importance of software testing and automated testing. It defines software testing as verifying that software meets requirements and works as expected. The document covers different types of testing and why automated testing is needed to reduce costs, protect reputation, and address difficulties in testing. It provides examples of unit testing simple objects, objects with dependencies, and user interfaces to illustrate how to implement automated tests.
Git code reviews
Code reviews improve code quality and transparency by providing a discussion platform to foster continuous self-improvement. They reduce bug fixing and new feature implementation times by catching issues early. GitFlow workflow with merge requests enables code reviews. Developers start a feature branch, push commits to the central repository, and create a merge request for review. Reviewers test the code locally, check for bugs, quality, and style. They discuss improvements in the merge request before accepting it to merge into the main branch.
User story workflow (eng)
