Continuous integration, testing, and delivery processes aim to provide fast feedback on code changes. This is done through frequent automated testing and deployment of code changes. Some key aspects discussed are:
- Continuous integration involves automatically testing code changes through builds and running automated tests. Frequent and immediate feedback is the goal but all tests may be too time-consuming.
- Continuous testing executes tests early and often based on code modifications to provide quick feedback.
- Continuous delivery deploys code changes to testing environments after builds to allow more testing, including performance and load tests. Continuous deployment then automatically deploys to production.

Static analysis is a static testing technique that analyzes source code without executing it. It can find faults like unreachable code, undeclared variables, and array bound violations. Some key advantages are that it can find faults difficult to see otherwise and provides an objective assessment of code quality. However, it also has limitations like not being able to distinguish fail-safe code from actual faults. Reviews are also useful for finding faults early and help achieve consensus, while inspections are more formal reviews.
The document provides an agenda for Day 2 of an ISTQB Foundation Level training which includes the following topics: test design techniques like test analysis, test design, equivalence partitioning, boundary value analysis, use case testing and experience-based testing. It also discusses test management topics like test leader and tester roles and responsibilities, test plan vs test strategy, estimation techniques, configuration management, risk based testing, exploratory testing and defect management. The last sections provide overviews of tool support for testing and an exercise on classifying different types of triangles based on side lengths.

This document discusses static testing techniques, including reviews. It describes the review process, roles in reviews, types of reviews, and static analysis using tools. Reviews are a formal process typically involving planning, preparation, a review meeting, rework, and follow-up. Roles include the moderator, author, scribe, and reviewers. Types of reviews serve different purposes at different stages. Static analysis tools can check coding standards and metrics, as well as code structure.
This document discusses software coding standards and testing. It includes four lessons:
Lesson One discusses coding standards, which define programming style through rules for formatting source code. Coding standards help make code more readable, maintainable, and reduce costs. Common aspects of coding standards include naming conventions and formatting.
Lesson Two discusses software testing strategies and principles. Testing strategies provide a plan for defining the testing approach. Common strategies include analytic, model-based, and methodical testing. Key principles of testing include showing presence of defects, early testing, and that exhaustive testing is impossible.
Lesson Three discusses software testing approaches and types but does not provide details.
Lesson Four discusses alpha and beta testing as
Agile Testing: Best Practices and Methodology Zoe Gilbert
Agile testing focuses on delivering value to customers through frequent testing and feedback. It differs from the traditional waterfall model which separates development and testing. The document discusses four main agile testing methodologies: behavior driven development, acceptance test driven development, exploratory testing, and session based testing. It also covers the agile testing quadrants framework and how companies can implement best practices for agile testing.
Exploratory testing is a hands-on approach where testers are involved in minimal planning and maximum test execution. The planning involves creating a test charter and objectives, while test design and execution are done in parallel without formally documenting test conditions, cases, or scripts. Some notes are taken during testing to produce a report afterwards. Use case testing identifies and executes the functional requirements of an application from start to finish using use cases. SDLC deals with software development/coding while STLC deals with validation and verification of software. A traceability matrix shows the relationship between test cases and requirements.
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

Mitigating the Impact of State Management in Cloud Stream Processing SystemsScyllaDB
Stream processing is a crucial component of modern data infrastructure, but constructing an efficient and scalable stream processing system can be challenging. Decoupling compute and storage architecture has emerged as an effective solution to these challenges, but it can introduce high latency issues, especially when dealing with complex continuous queries that necessitate managing extra-large internal states.
In this talk, we focus on addressing the high latency issues associated with S3 storage in stream processing systems that employ a decoupled compute and storage architecture. We delve into the root causes of latency in this context and explore various techniques to minimize the impact of S3 latency on stream processing performance. Our proposed approach is to implement a tiered storage mechanism that leverages a blend of high-performance and low-cost storage tiers to reduce data movement between the compute and storage layers while maintaining efficient processing.
Throughout the talk, we will present experimental results that demonstrate the effectiveness of our approach in mitigating the impact of S3 latency on stream processing. By the end of the talk, attendees will have gained insights into how to optimize their stream processing systems for reduced latency and improved cost-efficiency.

Technical Test Analyst Tasks in Reviews
Technical Test Analysts must be active participants in the technical review process, providing their unique views. All
review participants should have formal review training to better understand their respective roles and must be
committed to the benefits of a well-conducted technical review.
This includes maintaining a constructive working relationship with the authors when describing and discussing review
comments. For a complete description of technical reviews, including numerous review checklists.
Technical Test Analysts normally participate in technical reviews and inspections where they bring an operational
(behavioral) viewpoint that may be missed by developers. In addition, Technical Test Analysts play an important role in
the definition, application, and maintenance of review checklists and defect severity information.
Regardless of the type of review being performed, the Technical Test Analyst must be allowed adequate time to prepare.
This includes time to review the work product, time to check cross-referenced documentation to verify consistency, and
time to determine what might be missing from the work product.
A good review includes understanding what is written, determining what is missing, and verifying that the described
product is consistent with other products that are either already developed or are in development.
For example, when reviewing an integration level test plan, the Technical Test Analyst must also consider the items that
are being integrated. Are they ready for integration? Are there dependencies that must be documented? Is there data
available to test the integration points?

6. Using Checklists in Reviews
Introduction
Checklists are used during reviews to remind the participants to verify specific points during the review. Checklists can
also help to de-personalize the review, e.g., "this is the same checklist we use for every review, and we are not targeting
only your work product." Checklists can be generic and used for all reviews or focused on specific quality characteristics
or areas. A targeted checklist might concentrate on security issues or performance efficiency issues.
The most useful checklists are those gradually developed by an individual organization, because they reflect:
The nature of the product
The local development environment
Staff
Tools
Priorities
History of previous successes and defects
Particular issues (e.g., performance efficiency, security)
Checklists should be customized for the organization and perhaps for the particular project. The checklists provided in
this chapter are meant only to serve as examples.
Some organizations extend the usual notion of a software checklist to include “anti-patterns” that refer to common
errors, poor techniques, and other ineffective practices. The term derives from the popular concept of “design patterns”
which are reusable solutions to common problems that have been shown to be effective in practical situations
Neeraj Kumar Singh
7. Using Checklists in Reviews
Architectural Reviews
Software architecture consists of the fundamental organization of a system, embodied in its components, their
relationships to each other and the environment, and the principles governing its design and evolution.
Checklists used for architecture reviews could, for example, include verification of the proper implementation of the
following items, which are quoted from:
“Connection pooling - reducing the execution time overhead associated with establishing database connections by
establishing a shared pool of connections
Load balancing – spreading the load evenly between a set of resources
Distributed processing
Caching – using a local copy of data to reduce access time
Lazy instantiation
Transaction concurrency
Process isolation between Online Transactional Processing (OLTP) and Online Analytical Processing (OLAP)
Replication of data”

Code Reviews
Checklists for code reviews are necessarily very detailed, and, as with checklists for architecture reviews, are most
useful when they are language, project and company-specific. The inclusion of code level anti-patterns is helpful,
particularly for less experienced software developers. Checklists used for code reviews could include the following items:
1. Structure
Does the code completely and correctly implement the design?
