Software Development Tools Quiz

Agile Testing

• Agile testing is an approach to software quality management
• It focuses on continuous delivery and quality management
• It's different from traditional methods, which emphasizes "whole team" approach
• The entire team, not just testers, is responsible for quality
• Key aspects include software quality, agile testing quadrants, and selected testing methods

Continuous Delivery

• A presentation from Prof. Olivier Liechti highlights Docker tutorials and unit tests as key aspects.
• A 22-minute video by Arnaud showcases essential tools including ESLint (styling checks), SonarCloud (static analysis), Travis CI (delivery pipelines), and GitHub pages (Web deployment)
• The presenter highlights that continuous integration and delivery are a first step, followed by quality assurance aspects
• This emphasizes the need for thorough checking of all aspects before public release.

Motivation

• The presentation emphasizes the need for a fast validated learning cycle to stay competitive in the dynamic software engineering environment
• It examines how software engineering practices and tools help maintain a fast validated cycle
• Questions raised include how to balance speed with quality, how frequently to integrate code, and how to encourage collaboration in software development.

Continuous Integration

• The integration of components may be painful when done less frequently
• Integration should be made very frequent
• Frequently doing smaller tasks improves the quality and encourages automated procedures
• Successful continuous integration requires tools, culture, processes, and discipline

Integration is a PITA

• Team members often work on various components in parallel
• Integration into a product is often painful
• Continuous integration techniques are methods for alleviating the pain of integration.

Make Integration Very Frequent

• One big task is far more painful than various small tasks
• Frequent feedback enhances iterative refinement of tasks
• Repeated tasks enhance efficiency and inspire automation.

Tools & Processes

• Tools aid in effective collaboration and smooth coordination
• Procedures in software development should be clear
• Communication and discipline among team members are key aspects.

In Practice

• Maintaining a code repository is necessary
• Daily commits are important to base development on
• Automating the build and making it self-testing speeds up code release and reduces errors
• Immediate feedback about the current release state is helpful

Continuous Integration - Team Happiness

• Frequent commits enable immediate software build verification
• An effective way to identify potential issues at the earliest possible point
• Establishing a CI system is comparatively easy

Don't Stop There

• Continuous integration alone is insufficient. Customer needs should be a primary focus.
• A working software binary, tested daily, does not guarantee customer satisfaction
• Customers typically don't have access to internal binary releases and often need fully functional products.

Continuous Integration and Continuous Delivery

• CI is a narrow scope, developer-centric process focused on validated software packages
• CD has a broader scope, involving the whole team for deploying user-available features.

Quality Pipelines - The Last Mile

• Software development involves a "last mile" process encompassing the product being delivered to the customer.

Agile Testing Quadrants

• The "Agile Testing Quadrants" (Q1-Q4) are a model to organize software testing techniques
• Q1, Q2, Q3 and Q4 represent different testing approaches

Unit Tests

• Programmers use programming languages in "source files" to write code instructions
• These are later translated to machine language so machines can understand
• Specific "blocks" of source code need validation at various levels through testing
• A unit test focuses on validating one aspect of a specific part of code

Functional Tests

• Functional tests validate that software performs as intended by users
• Defining usage scenarios or test cases is a key step in this type of testing
• Test cases should outline steps users take and expected outcomes

Manual Functional Tests

• Test cases, especially when done manually, can be time-consuming
• This can lead to false sense of confidence in project status, especially if testing is infrequent
• This process can create unnecessary overhead in development
• Frequent releases help prevent significant issues in a product

Automated Functional Tests

• Tools for simulating human users in software testing can be effective
• Maintaining, writing, and keeping them up-to-date can be time-consuming
• Automated tests for functions tend to be slower than integration tests
• Automated testing is often done at a later stage, rather than initially

Behavior-Driven Development (BDD)

• A BDD method helps business analysis, developers, and testers communicate more effectively
• BDD is a framework to describe specifications in a way that's human-readable but interpretable by machines
• It allows quicker validation of requirements

Integration Tests

• Integration tests confirm interactions between various units of software, whereas unit tests are specific to isolated units
• It examines how different parts relate and interact in combination
• They are typically slower than unit tests but provide additional validation beyond functionality or isolated components

Systemic Qualities

• Developing software requires consideration of various factors, including performance, availability, security, and scalability
• Developers should ensure these factors receive attention alongside functionality.

HOW TO AVOID ISSUES

• Team awareness about system quality characteristics is crucial
• Measuring performance and efficiency early and often is also part of improving practices
• Integrating performance tests and security features into CI pipelines for continuous delivery is important

Jira Development Process

• A process for managing developments
• The process emphasizes a demo session for joint decision between development and product groups.
