Software quality is the software functionality and performance to meet user needs and expectations of the level.With the IT industry in various extensive and thorough application of software quality become important factors in general.How to effectively improve software quality, and enhance the competitiveness of software products, the software business management and technical staff common problems.
Software Quality is extremely heavy
Software quality is extremely heavy, software quality is one of the core competitiveness.Present and future competitiveness of software companies is not only reflected in the diversity of product types, product features advanced, more embodied in the product quality stability and reliability.The deepening field of software applications designed to gradually increase the complexity, shorter development cycles continue, the quality requirements gone up, the software enterprises are facing great challenges.
Users of the software product quality requirements continue to increase, prompting software companies to improve software quality as a strategy for enhancing competitiveness.Improve software quality factor in where?Software design techniques can be used to enhance software process management, the implementation of software testing methods.Improve software quality from a significant level of return on investment and the implementation of other aspects can be compared to the implementation of effective software testing, to improve the efficiency of software testing, software quality is to ensure that the most significant way.
Software testing is through technology, processes, tools, personnel and management tools, testing software documentation, software, intermediate products and final products, find and report software defects, errors and risks of expertise.By tracking defects, errors and risks of the amendment process to ensure that software products, intermediate products, and documentation meet the needs of the software engineering process and the end user needs.
Software Test Innovative Way
Software testing is still in its infancy in China, various software testing methods, techniques and standards are still in the exploratory stage.Generally small size of the domestic software industry, the lack of experience in large-scale software products, the development process not standardized, which determines the domestic software quality and testing industry, must be based on the domestic industry status, determine the software quality goals and test strategy methods, rather than copy the mature foreignsoftware companies testing methods.
1. The concept of innovation
Determinants to improve software quality software testing is not technology, but on software quality and testing of ideas.Only by improving software quality up to the height of the development of corporate strategy, in order to fundamentally solve the problem.Over the years, the domestic software industry, lack of emphasis on software quality, software testing role for the lack of awareness, resulting in the progress of the project due to quality problems caused by delayed or even fail.
In order to completely change the passive phenomenon, corporate executives must manage ideas, resources, support and other aspects of software quality and testing departments to provide full support.Software project manager must adhere to software development and software testing of parallel processing and the mutual coordination.With software developers and software testers attention.
The concept of innovation do not just lip service, and to implement specific action, through effective software quality and testing processes driven by process improvement to increase.Through effective organization and management, the formation of great importance to software quality proud to be ashamed of contempt software quality work atmosphere.
2. Process Innovation
Decided to software quality testing process.The same as software development, software testing, test requirements need to be collected to determine the test strategy, design, test, test execution, analysis and testing process.Software testing is not the final stage of software development, but throughout the entire life cycle of software projects.Decision is the key to success or failure of software testing software testing requirements are complete, accurate, effective and practical testing strategy is to test whether the design covers the test requirements.
Software testing process is not a rigid mechanically, nor is it to add a random choice.Software quality management and business development teams need to project technology companies, Resources for the project characteristics and customer needs, from software quality assurance, project schedule and cost of test, etc., to optimize the design and continuous improvement of process management.The project cycle is long, wide application field, high quality requirements on the software, you must develop and comply with rigorous testing process.
Testing process innovation within the company goal is to improve the project development and implementation of quality management system.Production optimization project, track and measure processes and products, making the production processes and products in each stage can be controlled and measurable state function to ensure that products meet customer requirements and schedule.
3. Technology Innovation
Software testing is a software engineering expertise, rather than simply testing the software easily find someone to run a few times that the software, you can find all the software problems.As mentioned earlier, the software testing requirements and test design is a key factor in software testing results, therefore, focus on technological innovation to enhance the test is designed to test the requirements and design innovation.
Technological innovation in software testing, to avoid falling into the pursuit of automatic test technology transition errors.Automated testing can indeed significantly improve some aspects of test efficiency and accuracy, but the automated testing software is only suitable for testing the quality of certain aspects (such as performance testing, regression testing, etc.), about 80% of software defects by manual testersTesting found.
For some special needs software features automated testing, need to strengthen the development of software testing tools, but not all rely on existing test tools on the market.This is because the function of many commercial tools, expensive, training and learning period is very long, poor choice will result in tremendous waste.
4. Management Innovation
Software test management goal is to achieve software quality, schedule, cost the best balance between.Management requires effective management of the testing, software development teams, quality assurance and testing team to work together with planning, organizing, leading, controlling and other means to build effective teams to develop comprehensive testing process, good test design, effective implementation of the teststrengthen the process of tracking, so the successful completion of quality assurance and testing tasks.
Innovation is the core of test management software quality and testing team-building, software quality and testing is technology-intensive activities, the team's knowledge structure, creativity and cohesion is to ensure the testing process, testing techniques based on the full implementation.Quality and testing team-building and training the key is to set a variety of technical and management personnel, effective communication, form a good evaluation and promotion mechanisms.
Another focus of the test management innovation is the test management platform.Construction of the test project management, including integrated systems, products and projects to achieve effective management of data and sequence control, so that project data transparency, effective transmission of technical knowledge, project quality and progress of digitization, graphic.According to the company's current situation, the purchase of commercial software test management tool software testing can also be internally developed management tools.
Software Testing Technology Roadmap
If the software testing is called a test strategy, test strategy to play a practical significance, we need to test the test strategy into tactics.Testing of the "Road" and "skill" seamless integration to a significant, sustained, gradual improve software product quality.Implementation of the software testing process is a series combination of tactics, involving the test team building, process design, testing platforms, test management and other aspects.
1. Test team building
Ministry of the test team can test can also be a test group.Company size determines the size of the test team and organization.Test team-building need to perform two principles: first, the test team must be independent of the development team, not affiliated with the development team to achieve the independence and impartiality of the test; second, the test team must have clearly defined objectives, that is foundand reporting software defects, promote and confirm the bug fixes, software development process improvement to help improve the overall quality of the software.
Software testing team size can be set according to multiple posts, each post with a clear job responsibilities, for example, test manager, test project manager, test team leader, test architect, senior test engineers, test engineers.Test for the newly established team, you can serve more than one position, complete a number of test tasks.The total number of testers and developers should adapt better to between 1:1 to 1:2.
2. Process Design
Testing process must be designed to correspond with the software design process, the basic testing process including test requirements analysis, test plan design, test case design, test execution, test evaluation, test summary and so on.
According to the software requirements and software design needs analysis to test specifications, test requirements analysis is a clear need for the test object, characteristics, scope and methods to develop test plans, determine test strategy.
Test plan is designed to test the efficient allocation of processes, people and tools to make full use of existing resources, the progress of the project plan, organizing an effective test.The output of the test plan design test plan is a document, it is the programmatic document guiding the activities of software testing documents.
Test case design is a specific test content and methods of guiding the key, and if necessary the implementation of automated testing, test case design also need to rely on generating a corresponding test script.The output of test case design is different types of test cases must be standard and consistent form of the design, review, store, update.
New test execution and reporting is the stage of software defects, according to the progress of software projects, assign test content, build a test environment, run the test program depend on test cases and procedures documentation.Is the output of test execution bug reports, testing, progress reports.
Testing and evaluation is a measure of the efficiency and effectiveness of software testing process.Test evaluation of the implementation of the input is the test case, software defect report data.Test evaluation of the effectiveness of the output, including test cases, the type and effectiveness of software defects analysis, testing, progress and effectiveness of the analysis.
Summary of the testing process including test daily or weekly summary of the process, including test items after the end of the test project summary.The output is a test summary test summary report, the overall evaluation of software quality, the problems that test, an improved method and process of testing a total effective experience.
3. Test Platform
Test platform technology platform, including test design and test management platform.Test test environment technology platform, including design, set design or testing tools.Test test management platform, including system design documentation, test version of configuration management, defect database design, testing, progress and quality analysis system.
Testing technology platform need to test the contents of test plan and test environment requirements, organizational software, hardware, databases and networks, which often is a more time-consuming work, and it affects the accuracy of the test must be tested as soon as possiblecompleted the initial stage, the best use of effective methods to build a test environment to back up save for the future, you can quickly recover, re-use.
Test management platform, the complexity of test management, test management platform enables a good test management personnel to facilitate the tracking, query, analysis and testing progress, staff performance assessment test to evaluate the overall quality of the test.Technical staff for testing purposes, you can easily find the test object and test documents, reports and output test results and share test data and improve test efficiency.
4. Test Management
Management attention to testing personnel, processes, products and change the three elements of the interaction, test management including project planning and organizational structure management, testing management, time, resources and quality management, document management and team management.Test manager, test project manager and test team leader is the main executor of test management, need to test team members, developers, corporate managers closely.
In order to strengthen test management, test data need to ensure smooth flow of information, so the test team, development team, quality assurance, effective communication between teams.Other content includes test management team members to participate in various training and objective assessment of the positive performance, identify project risks test and realize their talent, information sharing, progress control, to avoid risks, reduce costs and improve quality.
Conclusion:
Improve software quality is to improve an important factor in the competitiveness of products to enhance the software testing and innovation is a significant practical method to improve software quality.Software testing is a gradual process of innovation, from the establishment of a complete quality management system to start, through team building, optimizing processes, technology innovation, strengthening management, and staff, the harmony of process and technology to improve software quality and can be pre-testedcontrolled.
