論功能性與性能如何提高軟件的質(zhì)量

內(nèi) 容 摘 要

摘隨著軟件規(guī)模的不斷擴大，軟件設(shè)計的復(fù)雜程度不斷提高，軟件開發(fā)中出現(xiàn)錯誤或缺陷的機會越來越多。同時，市場對軟件質(zhì)量重要性的認識逐漸增強。所以，軟件測試在軟件項目實施過程中的重要性日益突出。

軟件功能性測試是軟件質(zhì)量保證的關(guān)鍵技術(shù)，在軟件生命周期中占有重要的地位。理論上軟件本身的缺陷都可在功能性測試階段被暴漏，因此軟件功能性測試方法是提高軟件可靠性及軟件質(zhì)量最有效、最直接的方法之一。

性能是軟件在市場競爭中一個強有力的競爭點，性能的測試與優(yōu)化對于軟件整體提升自己的性能，贏得市場的份額具有決定性因素。性能測試的主要目的就是驗證一個軟件產(chǎn)品可以允許多少用戶并發(fā)訪問，性能指標如響應(yīng)時間、CPU和內(nèi)存占用率是多少。一般來說這種測試無法手工做，需要借助于工具，如LoadRunner等等。

Abstract

With the expansion of the scale of software, increasing the complexity of the software design, errors or defects in the software development more and more opportunities. At the same time, the market recognition of the importance of software quality gradually increased. So, the importance of software testing in software project implementation process is becoming more and more prominent.

Software functional testing is the key technology of software quality assurance, occupies an important position in the software life cycle. Software itself defects can be theoretically was exposed in functional testing phase, so the software functional testing method is to improve the software reliability and software quality as one of the most effective and most direct way.

Software performance is a strong point of competition in market competition, performance testing and optimization software for overall improve their performance, win the market share of the decisive factors. The main purpose of the performance test is to verify a software product allows concurrent access to many users, the performance indicators such as response time, CPU and memory usage rate is how much. In general the test cannot be made by hand, need the help of tools, such as LoadRunner, etc.

key words:functional testing,functional testing process,functional testing, performance testing,virtual users,load test,stress test,transaction,the collection point.
