Resize window Resume autoscroll Select track Show timestamps Transcripts Options software testing life cycle (stlc) phases and concepts (stlc) is a set of defined stages or phases involved in the testing process of a software application. the various stages involved in stlc are: ● requirements study & verification: this phase involves the understanding of the functionality and verifying the testability of requirements. the qa lead clarifies any requirements and generates a review of defects and query resolutions. ● effort estimation: this phase involves revisiting the estimation made during the proposal stage. the qa manager revises the estimation and provides the updated figures. test planning and design in stlc test planning the qa manager creates a high-level test plan to provide a broad outline of the testing process. test analysis and design the qa lead creates a detailed test plan, traceability matrix, and test cases. a sr. test engineer creates the traceability matrix and test cases, while a jr. test engineer creates the test cases. review and selection the sr. test engineer also reviews the test cases and selects the test cases for automation if necessary. construction the sr. test engineer and jr. test engineer create and record the automation scripts and procedures for testing. testing execution and implementation testing cycles (execution) this phase involves the iterative execution of test cycles by jr. test engineer. the detailed test reports and defect reports are generated. system testing and implementation the sr. test engineer and jr. test engineer execute performance, stress, and other system tests and generate a test summary report, system testing reports, documentation, and metrics reporting. post implementation this phase involves evaluating all processes of testing and analyzing post-implementation defects. the qa lead generates the project closure, process improvement plan, and defect prevention inputs. throughout the stlc phases, different teams and individuals take ownership of the activities and are responsible for delivering the required deliverables. sdlc vs stlc: understanding the differences software development life cycle (sdlc) the software development life cycle (sdlc) is a methodical approach to software development that encompasses all the phases of development, including requirements gathering, design, construction, testing, and maintenance. software testing life cycle (stlc) on the other hand, the software testing life cycle (stlc) is a focused methodology specifically dedicated to the testing of a software system. it encompasses the entire process of testing from the design phase to the review and execution phase to ensure that a high-quality software product is delivered. relationship between sdlc and stlc stlc as part of sdlc stlc can be viewed as an expanded and in-depth version of the testing phase within the sdlc. comprehensive approach in essence, the stlc provides a comprehensive approach to software testing by including all the necessary steps to ensure that a software system meets the required specifications and is of a high standard. quality focus while sdlc covers the entire development process, stlc specifically focuses on ensuring quality through thorough testing methodologies. understanding test suites definition a test suite is a comprehensive grouping of tests that are specifically designed to verify the functionality of a software component. components this collection, also known as a validation suite, typically includes important information such as the test configuration, necessary preparation steps, the order in which the tests should be executed, and the actual tests themselves. purpose the purpose of a test suite is to ensure that the software component behaves as expected and meets its specified requirements. the v model in software development the v model is a software development lifecycle model that builds upon the traditional waterfall model. it is designed to incorporate both quality control and quality assurance into the software development process. in this model, each stage of software development is linked to a corresponding verification activity, ensuring that testing is a integral part of every phase of the software development life cycle. this model emphasizes the importance of testing in the software development process and ensures that it is considered and executed at every stage. when to stop testing 1 release deadline when the release deadline has been reached or has passed 2 test completion when all the planned tests have been executed and all have passed 3 pass rate threshold when a specific percentage of test cases have been successfully passed 4 bug discovery rate when the rate of bug discovery decreases below a predetermined level 5 optimal testing level when testing efforts have reached an optimal level 6 coverage target when the target for test coverage has been met 7 testing phase completion when the alpha and beta testing phases have ended 8 budget exhaustion when the budget allocated for testing has been exhausted considerations for stopping testing it's important to note that stopping testing should be a well-planned and informed decision, taking into consideration all relevant factors such as product quality, project deadlines, and budget constraints. product quality ensuring the software meets quality standards before release project deadlines meeting scheduled release dates and milestones budget constraints managing testing costs within allocated resources risk assessment evaluating potential impacts of remaining defects optimum testing in software development optimum testing is a state in software development where the cost of finding and fixing defects in the software becomes greater than the benefits of removing those defects. it is a balancing act between the effort required for testing and the benefits obtained from the results of testing. this is often visualized as a graph, where the number of defects in the software decreases over time, but the cost of finding and fixing these defects increases exponentially. the point where the cost and the number of defects intersect is known as the optimum testing point. it is a point at which further testing would not provide significant additional benefits, and therefore, testing can be stopped at this point. defining software quality quality for software refers to the extent to which a software system meets the expectations and needs of its stakeholders, such as customers, end-users, and the business. this involves ensuring that the software is functional, reliable, usable, efficient, secure, and maintainable, and that it meets the specified requirements within the agreed-upon budget and delivery schedule. software quality is a dynamic and multi-faceted concept that requires continuous assessment and improvement throughout the software development life cycle. quality control (qc) in software development — verification process quality control (qc) refers to a process of verifying the quality of a work product, such as a software module, to ensure that it meets the specified standards and requirements. — activities involved qc involves a series of activities, such as testing, inspection, and evaluation, to ensure the quality of the product before it is released to the customer. — objectives the objective of qc is to identify and rectify defects early in the development cycle, which helps in reducing the overall cost of development, ensuring that the product is delivered within the budget and timeline, and maintaining the quality of the product. quality assurance (qa) in software development definition quality assurance (qa) refers to a systematic and continuous approach to monitor and improve the processes involved in creating or maintaining work products. the goal of qa is to ensure that the end product meets the needs and expectations of the customer by fulfilling the specified requirements. focus areas qa activities encompass a range of practices, including but not limited to, requirements review, test cases and test data review, test results and defect review, and analysis of testing matrices. benefits these activities help to maintain the quality of the work product and improve the processes used to create or maintain it. the end result is a high-quality product that meets the customer needs and expectations in a cost-effective and timely manner. qa activities and outcomes requirements review ensuring requirements are clear, complete, and testable test case review verifying test cases cover all requirements effectively test data review confirming test data is appropriate and comprehensive defect review analyzing defects to improve prevention strategies testing metrics analysis evaluating metrics to identify process improvements differences between qa and qc: product vs process quality control (qc) quality control (qc) is a product-oriented approach, where the focus is on evaluating the developed work product to find defects. it involves activities such as testing and inspection and aims to take corrective measures to eliminate the defects. quality assurance (qa) quality assurance (qa), on the other hand, is a process-oriented approach that focuses on ensuring that the development and/or maintenance process is adequate to achieve the objectives of the system. the goal of qa is to prevent defects from occurring, rather than finding and fixing them after the fact. qa vs qc: activities and goals aspect quality assurance (qa) quality control (qc) focus process-oriented product-oriented goal prevent defects find and fix defects activities methodology development, standards creation, requirements review testing, inspection, evaluation timing throughout development after product creation approach proactive reactive in essence, qc is concerned with ensuring the quality of the end product, while qa is concerned with ensuring the quality of the process used to create the product. quality management system (qms) quality management system (qms) refers to the overall framework of policies, processes, and practices that an organization implements to ensure that its products and services meet or exceed customer expectations and comply with industry and regulatory standards. it encompasses various elements such as quality planning, quality control, and quality improvement activities aimed at reducing defects, improving efficiency, and enhancing customer satisfaction. a well-implemented qms enables organizations to identify and mitigate quality risks, streamline their operations, and continuously improve their performance. the pdca cycle for continuous improvement the pdca (plan-do-check-act) cycle is a continuous improvement process that involves four stages. in the first stage, the problem is identified and a solution is planned. in the second stage, the solution is implemented. in the third stage, the results are monitored and analyzed to determine if the desired outcome was achieved. in the final stage, actions are taken to improve the process or address any issues that may have arisen. this cycle is repeated continuously until the desired results are achieved. the pdca cycle is an effective method for addressing problems and promoting continuous improvement in an organization. cost of quality in software development the cost of quality refers to the expenses incurred in order to meet quality standards and avoid defects in a product or service. it encompasses a range of expenses, including the cost of preventing quality issues from arising, evaluating the quality of work, correcting problems that occur during development or production, and addressing issues that result in customer complaints or returns. these costs can be broken down into four categories: prevention costs, appraisal costs, internal failure costs, and external failure costs. by understanding the cost of quality, organizations can make informed decisions about how to allocate resources and improve their overall quality management processes. understanding risk in software projects 1 definition of risk a risk refers to a situation or an event that has the potential to cause harm or damage in the future. it is associated with an element of uncertainty and unpredictability, as well as the possibility of loss or harm if it materializes. 2 risk characteristics in other words, a risk is a possible negative outcome or threat that could result from a particular situation or decision. 3 risk in projects in software projects, risks can include technical challenges, resource constraints, schedule delays, and quality issues that could impact project success. risk identification in software projects systematic process risk identification refers to the process of systematically identifying potential threats or issues that may affect the successful completion of a software project plan. early detection the goal of risk identification is to identify and prioritize potential risks early on in the project, so that proactive measures can be taken to mitigate or eliminate these risks before they have a chance to cause harm to the project. evaluation and prioritization this process involves evaluating the likelihood of each potential risk and its potential impact on the project, in order to prioritize and address the most significant risks first. project success by effectively identifying and managing risks, risk identification helps to ensure that software projects are completed on time, within budget, and with the desired level of quality. risk mitigation planning proactive measures risk mitigation plan refers to a set of proactive measures and strategies aimed at reducing or eliminating the likelihood or impact of a potential risk. preventive action the goal of a risk mitigation plan is to take action before a risk becomes a reality and to minimize any negative consequences should the risk materialize. risk reduction the objective is to reduce the likelihood or impact of a risk and ensure the success of the project or organization. contingency planning for risk management definition a contingency plan is a pre-determined course of action designed to minimize the impact of a potential negative event. purpose it outlines the steps that will be taken to respond to an unexpected situation and manage its effects, in order to minimize the damage, it could cause to the project or the organization. function a contingency plan is essentially a backup plan that serves as a safety net in case of risks materializing, providing a roadmap for response and recovery. levels of software testing the process of software testing is a systematic and organized method of evaluating the software's functionality, performance, and overall quality. the software development approach has a significant impact on the design and execution of the testing process. typically, software is built by combining smaller units into modules and then integrating these modules to create the entire system. to effectively evaluate the software, testing is carried out at various levels, including unit, integration, system, and acceptance testing. each level of testing has a unique objective and approach, and is designed to identify different types of defects. by recognizing these different levels, the testing process can be optimized to ensure that all critical aspects of the software are thoroughly tested and validated. unit testing in software development smallest unit unit testing is a critical aspect of software development, where the focus is placed on the verification of the smallest unit of software design. object-oriented systems this unit is typically a class in an object-oriented system design, and it is the responsibility of the developers to carry out unit testing. automation tools with advancements in technology, there are now several tools available to automate the unit testing process, such as junit for java, nunit for .net, and dbunit for databases. early detection these tools aid in streamlining the testing process and can help catch bugs and defects early on, before they have the chance to escalate and cause bigger problems down the line. system testing activities system testing involves a comprehensive evaluation of an integrated system to assess its conformance to the specified requirements. it covers both functional and non-functional aspects of the system, including performance, reliability, scalability, and compatibility. the purpose of system testing is to verify that the system meets the required functional and non-functional specifications, ensuring that it functions as intended and delivers the desired level of quality of service. the results of system testing provide valuable information that helps in identifying and fixing any issues that may arise during the development process, ultimately leading to a high-quality end product. acceptance testing: evaluation by end-users definition acceptance testing is a crucial stage in the software development lifecycle where the software is evaluated by the end-user or customer to determine if it meets their requirements and expectations. purpose this testing process is performed to verify the functional and non-functional aspects of the software and is the final step before the software is deployed for operational use. criteria the acceptance criterion, which includes a set of test cases, is defined by the customer based on their specific requirements, and the software must pass these tests successfully before it can be considered for acceptance. goal the purpose of acceptance testing is to ensure that the software meets the needs and standards of the customer and is ready for use in real-world scenarios. who performs acceptance testing? customer testing acceptance testing is an important step in the software development process where the end-user or customer evaluates the product to ensure that it meets their specific requirements and expectations. in cases where the product is developed for a specific customer, they typically perform the acceptance testing. user group testing however, for software products that are developed for a more general audience, a representative user group is formed to conduct the acceptance testing. this group is comprised of individuals who are likely to use the product and their role is to ensure that the product meets the needs of the target audience and that it functions as expected. alpha testing in software development controlled environment testing alpha testing is a stage of software testing where the product is tested by the end customer or a representative group of customers in a controlled environment at the developer's site. developer observation during this testing phase, developers actively observe and record any usage problems or errors that arise. customer usage insights the primary purpose of alpha testing is to gather more information on how the customer will actually use the product, which can provide valuable feedback to the developers for further improvement. beta testing: real-world software evaluation external testing beta testing is the final stage of testing that takes place outside the developer's site. real end-user testing during beta testing, real end-users of the application use it in a live environment and provide feedback on their experience. pre-release testing this testing is typically done before the general availability (ga) release of the software product and is not supervised by the developers. user feedback collection the purpose of beta testing is to give the end-users a hands-on experience with the product and to gather valuable feedback on its usability, functionality, and any issues that may arise in a real-world setting. components to test in software applications the testing of a software application typically encompasses various components, including user interactions and workflows, business rules and validations, user interface elements and navigation, role-based access and security, field-level verification, error scenarios, inbound and outbound interfaces, system and user logs, configuration and master data, batch processes, scheduled jobs, reports, audit tracking and history reporting (if applicable), backup and recovery processes (if applicable), and database testing that includes sql, stored procedures, and triggers (if applicable). these components are tested to ensure the application functions according to the specified requirements and provides a seamless user experience. common testing project challenges unstable requirements the common difficulties that testers often encounter in their projects include: • unstable or evolving requirements domain expertise • lack of expertise in the specific domain under test time constraints • insufficient time dedicated to testing environment issues • unavailability or malfunctioning of the test environment additional testing challenges test data problems • absence of relevant test data team disagreements • disagreements between the testing and development teams on the nature of defects inadequate unit testing • lack of adequate unit testing by the development team frequent builds • frequent builds being released by the development team before the testing cycle is completed critical defects • presence of high-impact defects that impede the progress of the testing effort. verifying data transfer between modules in order to verify the data transfer process between two modules or applications, one needs to consider several key aspects. these aspects include the trigger mechanism in the source module that initiates the data transfer, the content and format of the data being transferred, and the manner in which the data updates the destination module. in case the data transfer process is file-based, the format of the files being transferred must also be taken into consideration. finally, it is important to verify the end-to-end functionality of the data transfer process to ensure that the data is successfully transferred from the source to the destination. risk-based testing approach risk identification risk-based testing is a structured approach for evaluating and mitigating potential risks in software projects. it's performed by following these steps:● identification of risks: the first step is to identify various types of risks associated with each requirement, such as business risks, compliance risks, and others. risk index calculation ● calculation of risk index: next, the risk index is calculated by multiplying the impact of the risk with the probability of its occurrence. this formula helps prioritize the requirements based on their associated risks. prioritizing requirements in risk-based testing requirement prioritization ● prioritization of requirements: based on the risk index, the requirements are prioritized and corresponding test cases are executed. this way, the testing effort is focused on the most critical requirements, ensuring that they are tested thoroughly to minimize the potential risks. benefits of risk-based testing risk-based testing helps to ensure that testing is focused on the most critical requirements, so that the software meets the customer's requirements and is of high quality. correct this is one of the defined phases of
