Software Development Quality Assurance
Custom software development is a multifaceted process that demands expertise, experience and creativity. Professional developers understand the importance of building a high quality product that will meet the requirements of clients and provide a satisfactory experience for the end user. Quality assurance is an integral part of software development that ferrets out any bugs or flaws before the product is released to the client.
QA Process Documentation
A review of the client’s requirements is the first stage of the software quality assurance process. Accurate and understandable documentation is fundamental to making the QA process flow smoothly. QA engineers review project documents for consistency, clarity and completeness.
The goal of documentation review is to ensure that system architecture and technologies can be executed and verified. Review of requirements and analysis of documentation help developers detect errors before they are executed, and ensure the client’s requirements are fully met.
Once the product’s requirements are clearly documented and understood, the QA team can move ahead with test planning, design and execution. In the test planning stage, a strategy is laid out for actions that need to be taken to accurately evaluate the product’s status.
Test planning includes composing test cases that provide detailed specifications for a single test’s inputs, execution, procedures, and expected results.
QA testing follows several steps:
- Requirement analysis
- Test planning
- Test design
- Feature testing
- Regression testing
- Usage analytics
- User monitoring
- Smoke testing
QA tests fall under one of three categories:
- Functional tests zero in on the product’s functionality, to ensure it meets the client’s requirements for quality user experience.
- Non-functional tests focus on the technical elements of a product, such as stability, performance, security, scalability and endurance.
- Maintenance tests are run after the product is launched, to ensure smooth ongoing performance.
Software Quality Assurance Processes
The quality assurance process is a methodical approach that determines a product’s functionality and durability, based on certain requirements and criteria. It entails testing various aspects of the product throughout the software development lifecycle.
Following are the most common QA testing processes:
- Unit testing assures the quality of individual units of source code, to ensure proper functionality.
- Integration testing combines individual modules of software and tests them as an integrated group.
- System testing is based on the product’s requirements and tests the entire system, to ensure it is compliant.
- Performance testing tests the entire system’s stability and responsiveness under a given workload.
- Security testing looks for weaknesses in the system that make its data and resources vulnerable to threats and breaches.
- Cross-platform testing ensures that the software functions flawlessly on various web browsers, operating systems, and devices.
- Test case updates are made to annotate whether the test passed, failed or is ready for a retest. It helps developers keep track of which tests have been executed, added, modified, updated, or deleted.
- Regression testing re-runs functional and non-functional tests to verify that the system’s functionality has not been compromised by subsequent code changes.
When and where the QA test process occurs depends on the specific project and the methodology used by the development team. While some software development methodologies postpone testing until after the product is fully developed, more modern approaches like Agile integrate QA testing from start to finish. Integrated testing saves time and money, speeding up the development process without compromising the end product’s quality.
The Agile QA Process
In projects developed with Agile methodology, the software quality assurance process is introduced at the project’s earliest stage, to eliminate problems as early as possible. With Agile, QA testing becomes an integral part of the software development lifecycle (SDLC), and is repeated with every sprint.
With the Agile QA approach, quality assurance is built in at every step, eliminating the need to backtrack later to fix bugs and flaws. Testing is done with the user in mind, to ensure a value-driven product. User-focused QA processes save time and money, and ensure a quality end-product that satisfies both clients and their target audiences.
Reporting QA Test Results
As part of the QA process, test results must be documented for developers and stakeholders. The QA team reports daily on any tests completed that day, and also keeps a test summary report that provides details on all the testing activities completed in a given time period. The summary report should include a comparison of test objective vs test results.
