"Is software unit testing really necessary? (Part 1)" focuses on the importance of unit testing and its Difficulties we are facing and shared the unit testing methods listed in the functional safety standards. Following the above, this article will discuss in depth how to complete testing tasks with quality and quantity while reducing time costs and improving testing efficiency during the unit testing process, and share current practical experience in the industry and related automated testing tools.

Unit testing can be done, but the project cycle is tight, what should I do?
However, when actually implementing software unit testing, there is also a cost issue that needs to be considered.
The competition in the software industry is relatively fierce. In an era when delivery is king, the market deadline for software release is a cruel problem that everyone has to face is life or death. How can we maintain both quality and quantity, that is, reduce the time cost caused by the introduction of unit testing?
If a worker wants to do his job well, he must first sharpen his tools. The first way to reduce costs is to utilize automated testing tools. There are currently available automated unit testing tools on the market, including open source and commercial ones.
Open source toolsUsually provide a testing framework for a specific language, and unit testers use the framework to write test code. The more commonly used open source frameworks include GoogleTest, Junit, etc. Since open source tools are tested by writing code based on existing testing frameworks, the requirements for general testers' programming skills are relatively high.
Commercial tools Provide visual automated testing tools that do not require large-scale test programming and focus testers' energy on the design of test cases rather than the execution of the test framework , so it will be more friendly to testers. Foreign tools have a higher market share of commercial tools. However, since 2019, these business tools have also been subject to domestic sales bans and service suspension renewals. Fortunately, some well-known universities in China have accumulated relevant technologies in the early stage. At present, there are a few domestic automated unit testing tools, such as SmartRocket from the Trusted Laboratory of the School of Software, East China Normal University. These tools are in automated execution. On the basis of this, what is more advanced than foreign tools is that it provides the core function of automatically designing high-coverage test cases, which can reduce the time investment of testers to a greater extent.
On the basis of using automated testing tools, CI (Continuous Integration) is adopted to integrate unit testing into the process of automated continuous integration, which can further reduce time costs and improve software launch efficiency. By using continuous integration tools such as Jenkins, when the module code is submitted, the code automation test sentinel is automatically triggered. When the test passes, the code submission is successful, otherwise the submission fails. In addition to unit testing, the automated test sentry can also add automated pipelines such as code static scanning. There are many successful cases of software continuous integration in the industry that can be used for reference. It is an intuitive manifestation of software quality assurance and high software development efficiency.

Conclusion: Haste makes waste, and patience in unit testing is a programmer's virtue.
Having written this, I believe everyone has a certain understanding of the importance of software unit testing and how to practice unit testing. If you are a practitioner in the software industry, I hope this article can bring you some new thoughts. To sum up, haste makes waste. For excellent software development engineers, patiently doing unit testing is a basic virtue worth cultivating. The future software foundation of the Metaverse depends on you.
