When it comes to software testing, ordinary people are basically half-knowledgeable. Its official interpretation refers to the evaluation and testing of software performance, usage, use value, etc. It is an important way to ensure software quality and improve software reliability.
With the passage of time, the connotation of software testing continues to enrich, and everyone's understanding of software testing continues to deepen. People realize that software testing is an active process of verifying and confirming software products. The ultimate goal is to find various defects in the entire development life cycle of software products as soon as possible, so as to assess whether the quality of the software reaches the release level. It is a key factor to ensure software quality.
In order to save costs and improve quality, more and more companies have begun to choose third-party testing agencies for software testing. As a third-party evaluation agency, whether it has professional evaluation qualifications is an important factor that affects the consideration of software development companies. As a prerequisite for providing highly professional evaluation reports, the requirements for third-party testing organizations are also relatively high.
Software testing is accompanied by the emergence of software. In the initial software development process, the software scale was small and simple, and the development process was random and disorderly. The meaning of software testing is also relatively narrow, which is only equivalent to debugging. The testing work is generally performed by developers concurrently with the purpose of correcting known problems in the software. The investment in testing is relatively small, and the testing work is involved late, usually after the code is formed and the product is completed.
1. The development history of software testing
In the 1960s (before the establishment of software engineering), engineers needed to perform tests to verify that the program was correct. The first official software testing conference was held at the University of North Carolina in 1972. In 1975, John Good Enough and Susan Gerhart published an article "Principles of Test Data Selection" in IEEE, and software testing was identified as a research direction. In the early 1980s, the horn of "quality" began to sound. The definition of software testing has changed. Testing is no longer simply a process of finding errors. It has begun to include software quality evaluation and various standards have been formulated. In the 1990s, testing tools became popular. By 2002, Rick and Stefan further defined software testing in the book "System Software Testing": Testing is to measure and improve the quality of the software under test, and the entire life of the engineering design, implementation and maintenance of the test software Cycle process.
Second, the purpose of software testing
Testing is the execution process of the program, the purpose is to find errors. And to ensure that the product has completed its promised or announced functions, that the product meets the performance and efficiency requirements, and that the product is robust and can adapt to the user environment.
Third, the meaning of software testing
Software testing can liberate programmers and after-sales service personnel. Software testing can reduce software quality risks and enable programmers to focus more on the algorithm and efficiency of the program. At the same time, the complete product that has been strictly tested also reduces the workload of after-sales service personnel.
Fourth, the value of software testing
In order to ensure that the performance, quality, and safety of the software meet the requirements, the third-party testing organization needs to conduct a series of evaluations and tests on the software, and provide a convincing evaluation report to meet the customer's requirements for software quality. Or provide authoritative third-party testing services for software companies and software purchasers to help customers complete software quality assessment and performance testing to ensure the smooth progress of customer transactions.
Five, the prospect of software testing
Based on the rapid development of the Internet in recent years, the popularization of mobile phones and 4G networks, and the promotion of other smart products, the proportion of software applications in daily life is rapidly increasing. Users have higher requirements for software quality and experience, and higher expectations for the frequency of software updates and the speed of new software releases. Coupled with competition in various industries, software developers need to release higher-quality software products at a faster frequency.
Therefore, the needs of enterprises for software testing will become greater and greater, and software testing will develop rapidly in the next 5-10 years. Because software companies rely on the quality of software products to occupy the market, the assertion that "there may be more bugs without testers, products, but this product cannot be made without R&D and product personnel." has become a thing of the past. Software testing will become the lifeblood of a software company's survival. Testing will not pass, and products will not get the opportunity to enter the market.
Therefore, choosing a reliable third-party testing agency with high credibility has become an important requirement of software companies, which indirectly promotes the emergence and development of third-party software testing agencies, and also produces a lot of software testing. The post has promoted the development of the software testing industry.
At present, the development of the software testing industry is relatively mature, but there is a huge gap in professional talents. There is a greater gap in professional talents who have a systematic knowledge and skill system and will use some tools, so there is still a lot of room for development in the future.
