Содержание слайда: Outline Software Quality Assurance Plan Definition of quality for software products Software Metrics Software Testing, types of testing

Содержание слайда: Outcomes Understand the key parts of the Software Testing process Know how to identify the metrics of software Be able to write a SQAP Have a clear understanding of what is Quality in software products

Содержание слайда: Software Quality Assurance Plan The purpose of the Software Quality Assurance Plan (SQAP) is to define the techniques, procedures, and methodologies that will be used at project to assure timely delivery of the software that meets specified requirements within project resources.

Содержание слайда: Software Quality Assurance Plan Set common templates (standards) Define the sequence of actions Ensure that standards and processes are used Conduct an analysis of completed projects Analyze and learn, using the defect data Use what you have learned

Содержание слайда: What is Quality? How do you understand the term Quality of software product? Is it rather about conformance to requirements? Is it rather about fitness of use?

Содержание слайда: What is Quality? Verification – The evaluation of whether or not a product, service, or system complies with a regulation, requirement, specification, or imposed condition. It is often an internal process. Contrast with validation. Validation -The assurance that a product, service, or system meets the needs of the customer and other identified stakeholders. It often involves acceptance and suitability with external customers. Contrast with verification.

Содержание слайда: Fault, failure and error Fault/defect – a condition that may cause a failure in a system, also called a bug. Failure/problem – the inability of a system to perform a function according to its specification, result of a defect. Error – a mistake made by software engineer or programmer

Содержание слайда: Cost of Quality (CoQ)

Содержание слайда: Software Project Metrics Tools for anyone involved in software engineering to understand varying aspects of the code base, and the project progress. They are different from just testing for errors because they can provide a wider variety of information about the following aspects of software systems: Quality of the software, different metrics look at different aspects of quality Schedule of the software project on the whole, some metrics look at functionality and some look at documents produced. Cost of the software project. Includes maintenance, research and typical costs associated with a project. Size/Complexity of the software system. This can be either based on the code or at the macro-level of the project and it’s dependency on other projects.

Содержание слайда: Seven basic Quality tools

Содержание слайда: Software Metrics: effects of proper usage Reduce cost by 15% - 20% by just measuring Create baseline of quality and productivity and compare against industry averages. Pinpoint opportunities for improvement. Ability to measure initiatives and measure ROI (return of investments).

Содержание слайда: Software Project Metrics: types Life Cycle Step metrics Costs and budget metrics Requirements’ change metrics Development process metrics Testing metrics Defect metrics Efficiency metrics

Содержание слайда: Software Project Metrics in Agile An agile version of the Goal Question Metric (GQM) strategy. The fundamental idea behind GQM is that you first identify: a goal that you would like to achieve, a set of questions whose answers are pertinent to determining how well you’re achieving that goal, and then the metric(s) that could help you to answer each question

Содержание слайда: Software Project Metrics General Project Metrics: Completed activities budget (percentage of completed tasks) Actual budget ratio of the planned budget ( Budget(actual) / Budget(planned) ) Dispersion (var) of costs (Budget(actual) - Budget(planned) ) Schedule execution ( Effort (actual) / Effort (planned) ) Dispersion (var) of schedule ( Effort (actual) - Effort (planned) ) Schedule delays ( ∑ delay time ) Coefficient of closed tasks ( closed tasks / planned tasks) Productivity

Содержание слайда: Software Metrics Requirements Metrics: Frequency of change in the total requirements set Rate of introduction of new requirements Traceability Volatility of requirements Percentage of defects as requirement as a root cause Number of requirement-related change requests Requirement Stability Index : 1- ((No of changed + No of deleted + No of added) / Total no of Initial requirements) x100

Содержание слайда: Software Metrics Product Metrics: Testing General Testing time Test cases metrics Passed/Failed Test Cases Not Run Test Cases Bugs Open/Closed Bugs Reopened/Closed Bugs Rejected/Opened Bugs Bugs by Severity Bugs by Priority

Содержание слайда: What is Testing of SW? Maintaining a set of techniques for detecting and correcting errors in a software products (testing process can be automated)

Содержание слайда: Testing Test Plan - a document describing the scope, approach, resources and schedule of intended test activities. It identifies amongst others test items, the features to be tested, the testing tasks, who will do each task, degree of tester independence, the test environment, the test design techniques and entry and exit criteria to be used, and the rationale for their choice, and any risks requiring contingency planning. It is a record of the test planning process.

Содержание слайда: Testing Master Test Plan: A single high-level test plan for a project/product that unifies all other test plans. Testing Level Specific Test Plans: Plans for each level of testing. Unit Test Plan Integration Test Plan System Test Plan Acceptance Test Plan Testing Type Specific Test Plans: Plans for major types of testing like Performance Test Plan and Security Test Plan.

Содержание слайда: Testing of SW? Who does the testing Programmers (developers) Testers Users (Alpha testing & Beta testing) Testing levels: Unit testing; Functional testing; Integration and system testing (regression test, smoke test);
