What is QA

💡 A broad term Quality Assurance, or QA (with quality assurance professionals) for short, is a procedure or group of actions to guarantee that a good or service satisfies requirements and quality standards. Planning, carrying out, and reporting testing is necessary to find flaws or potential quality improvement areas.

Maintaining a competitive edge in the market, providing a high level of quality goods and services, and improving customer happiness depend on quality assurance (QA). This proactive strategy prioritizes defect prevention over defect detection.

The project manager, quality assurance engineers, and software test engineers play a crucial role in QA testing by coordinating and overseeing the testing activities throughout the software development lifecycle. These project managers are responsible for defining the testing strategy, allocating resources, and setting timelines for testing milestones.

What is software testing

🧩 Software testing is a broad term (including unit testing), and it is a part of quality assurance (with quality assurance professionals). It runs a system or software program to identify flaws or confirm that it complies with requirements. Testing employs various approaches and procedures to evaluate the software's usability, security, performance, and functionality.

A crucial step in the software development life cycle, especially in an agile project, is software testing, which verifies that a system or application satisfies requirements and operates accurately and dependably. 

Software testing is a must to develop high-quality software solutions and better outcomes with developers who follow quality guidelines and offer a satisfying user experience. To guarantee the dependability and success of software applications and systems, meticulous planning, strict implementation, and ongoing development are necessary.

Exploring several modern QA testing methods

🔍 The difficulties presented by agile development, continuous integration, and the requirement for quicker release cycles have led to the evolution of modern QA testing techniques. Here are a few examples of contemporary QA testing techniques, reflecting the style of software testing:

💡Shift-left testing: Testing activities are incorporated early in the software development lifecycle using the shift-left testing methodology, a type of quality assurance. Early on, including quality assurance (QA) helps testing teams find errors to combat the high cost of errors more quickly, reduce rework, and enhance overall product compliance and product quality.

The shift-left approach to testing advocates for early involvement of testing activities in the software development process.

💡Continuous Testing: Automated testing processes may be carried out continuously during the development process, thanks to continuous testing integration into the CI/CD pipeline. 

This speeds up delivery cycles, guarantees quick feedback on testing scripts and code quality changes, and raises release reliability. Each project demands a tailored approach to testing, considering its unique user requirements and constraints.

💡Exploratory Testing: This method, a type of quality assurance, involves quality assurance engineers, software test engineers, and testers investigating the software program without using pre-written test cases. Testers and business analysts assess the user experience and find flaws by applying their creativity, intuition, and topic expertise. 

A systematic approach to testing, including creating testing scripts, ensures comprehensive coverage and mitigates risks effectively.

💡Behavior-Driven Development (BDD): The goal of behavior-driven development, or BDD, is to specify software behavior using acceptance criteria and user stories. Tools like Cucumber or SpecFlow are used to write tests and testing scripts in a human-readable manner, which makes it easier for alert developers (outcomes with developers), testers, business logic, and stakeholders to collaborate.

Business logic is crucial in QA testing as it defines the core functionality of a software application, defining data processing, rules application, and system decision-making. QA testing ensures that the software's business logic accurately reflects the requirements and specifications provided by stakeholders. This approach to testing verifies the alignment of the software's business logic with stakeholder expectations.

💡Test-Driven Development (TDD): Test-Driven Development (TDD) is a technique for development in which written tests are performed before implementing lines of code. Based on requirements, alert developers create automated testing processes and unit tests, after which they write lines of code to pass them. 

TDD contributes to test coverage, maintainability, and correctness of testing scripts and code quality. A risk-based approach to testing is also used, prioritizing testing efforts based on potential impact and likelihood of failure.

Testing VS Quality Assurance – How testing transforms your product into a user-favorite

🔍 As mentioned earlier, two vital steps in the process of software development are testing (including unit testing) and QA, both of which are critical to the success and compliance with requirements of the final product. Testing concentrates on finding human errors and confirming functionality, whereas QA includes a wider range of tasks to stop errors (and high cost of errors) and guarantee overall excellence. 

Testing also involves a proactive approach to testing, enabling rapid feedback and continuous improvement throughout the development lifecycle, reflecting the style of software testing. 

Let's delve more into these two steps.
