Unit3 software review control software
A software system is more than the code; it is a set of related artifacts; these may contain defects or problem areas that should be reworked or removed; quality-related attributes of these artifacts should be evaluated
Reviews allow us to detect and eliminate errors/defects early in the software life cycle (even before any code is available for testing), where they are less costly to repair
Most problems have their origin in requirements and design; requirements and design artifacts can be reviewed but not executed and tested
A code review usually reveals directly the location of a bug, while testing requires a debugging step to locate the origin of a bug
Adherence to coding standards cannot be checked by testing

Traceability matrix
A traceability matrix traces requirements to tests, code, and design specifications. It provides backward traceability from tests to requirements and forward traceability from requirements to tests and code. The matrix links high-level requirements to lower-level tests, design documents, and code files. This allows one to ensure all requirements are tested, identify untested requirements, and determine which tests need updating when requirements change.
Formal Verification
Formal verification involves proving the correctness of algorithms or systems with respect to a formal specification using mathematical techniques. It can be done by formally modeling a system and using theorem proving or model checking to verify that the model satisfies given properties. Theorem proving uses logical deduction to prove properties, while model checking automatically checks all possible states of a finite model against temporal logic properties. Both approaches have advantages and limitations, but formal verification can help find bugs and prove correctness of systems.

Acceptance testing plone sites and add ons with robot framework and selenium
Acceptance tests are high-level tests to verify the completeness of user stories (end user features) for a developed product. It is said that while lower level unit and integration tests confirm that the product has been made right, only the acceptance tests confirm that the product actually does the right thing.
Robot Framework is a generic test automation framework for acceptance testing and acceptance test-driven development. The key feature of Robot Framework is its extensible test syntax, which allows to write tests in a business-readable domain-specific language, including BDD (behavior driven development) style for executable acceptance criteria.
Selenium is a browser automation framework. It allows to use real browsers in acceptance testing so that all effects of CSS and JavaScript taken into account, including possible differences between different browsers.
This talk walks through alternative ways for using Robot Framework and Selenium to perform acceptance testing, including
* testing live sites (readonly)
* testing sandboxed Plone sites with live data (beforestorage + demostorage)
* testing sandboxed Plone add-ons (plone.app.testing + plone.app.robotframework)
* testing Sphinx documentation (while generating screenshots)

SQA
Software Quality Assurance (SQA) is a planned and systematic approach to evaluate software quality and adherence to standards, processes, and procedures. SQA activities include product evaluation to ensure standards are followed and process monitoring to ensure appropriate steps are carried out. SQA is related to assurance activities like configuration management monitoring, verification and validation monitoring, and formal test monitoring. SQA metrics are used to track issues found during reviews. SQA should be applied during all phases of the software development life cycle from concept to operations.
Modernizing Testing as Apps Re-Architect
Applications are moving to cloud and containers to boost reliability and speed delivery to production. However, if we use the same old approaches to testing, we'll fail to achieve the benefits of cloud. But what do we really need to change? We know we need to automate tests, but how do we keep our automation assets from becoming obsolete? Automatically provisioning test environments seems close, but some parts of our applications are hard to move to cloud.

Mainframes and Cobol Migration - Tools based - Arkin Software
Arkin Software offers complete migration solution to retire Mainfarmes and Cobol based Applications. It is a migration framework- comprising of a set of automated tools; migration methodology; and experienced consultants that facilitate factory-like precision.
There are three Converter tools.
(a) GUI converter converts legacy GUI into web-structure, RIA technologies or thin-client GUI, with similar look & feel.
(b) Code converter converts business logic of the legacy code into equivalent java.
(c) DAO converter converts Data calls into a chosen persistent framework like SPRING JDBC or JDBC.
Besides these, there are two extremely important tools.
(d) Analyzer: It is this tool that helps us even if there is limited or non-existent documentation and application knowledge. This tool dives through legacy code, builds metrics and relationships to help our team to size and understand the legacy complexity and accurately estimate the migration effort.
(e) Traceability Generator. It maps legacy code to converted java code in a spreadsheet format. This traceability matrix serves two purposes: One is to ensure that no legacy code is missed out during conversion; and the other is to facilitate client’s internal teams to catch up with migrated Java code.
Arkin Software’s unique approach to migration is architecture-centric. That means, we start with the target architecture and migrate the legacy to that target. Never one-to-one migration. Because, migrated applications must live in production for another 20-25 years, which is possible only if they are built on right architecture. Nobody likes applications that may look like Java, but stink like legacy.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Editor's Notes
- DO-178B objectives imply rather than mandate explicitly a V-Model. Likewise, other standards (e.g. IEEE 12207, IEC 61508, ISO 26262) are V-Model based. As the DO-178B assurance level becomes more onerous, evidence from deeper within the V-Model is required. All levels (A through to D) demand a lot of assurance for Requirements, but only levels A and B need detailed SC assurance.
- Summary of Tables in Annex A of DO-178B. Note, objectives applying to all four levels are concentrated on Requirements processes – in fact, no SC assurance is required for Level D! This “requirements-based” theme is reflected also in the body of DO-178B (refer 6.4.2 and 6.4.3), and is taught by DO-178B gurus (e.g. Mike DeWalt). Concentrating effort on code based assurance to the exclusion of requirements assurance is a common but gross misinterpretation and misrepresentation of DO-178B. Levels A and B require significantly more effort because, code (SC and EOC) and the coding processes require additional verification, and independent satisfaction of multiple objectives is required.
