The investment in testing for financial trading systems far exceeded that of other systems, with tedious test steps repeatedly executed and a low ROI. As projects and personnel changed, uncontrollable factors inevitably introduced, a common situation being the modification of a field output from Interface A impacting the results of Interface B. With each version release, risk also accumulated. Theoretical Knowledge How to Measure the Value of Automation? An automation testing ROI = (Manual Execution Time) * (Number of Runs) / (Development Cost + Maintenance Cost) Which Features Should Be Automated?

Starting from my academic years, I’ve been working with C++ for over ten years. So, why do I need to learn other programming languages? Work experience: Lacking experience in elegant module design, C++ syntax is freeform. Learning other languages helps me guide the development of more elegant designs. I often use them when writing some tools. The design principles for low-level libraries and business modules are also becoming clearer.

C++ cross-platform development. Commonly encountered on Chinese operating systems: error C2001 - constant contains a newline character. Visual Studio cmake organizes the project compilation script, generating a temporary solution under the windows system for development. The reason for cross-platform compatibility is that the file encoding is chosen as utf-8. The cited reference provides a detailed explanation of the causes of the problem from first principles. Regarding encoding, MSVC has dedicated compilation options /source-charset and /execution-charset.

The Linux platform is very simple: du -sh * – just one line of code solves the problem. What about Windows? With many disks and a desire to clean up, with numerous files, the system’s built-in Resource Manager is too slow to calculate folder sizes, making you want to give up. Everything For developers working on the windows platform, you probably haven’t personally used everything, and should at least have heard of it.

Static blog themes, the mainstream is based on foreign templates, modified and adjusted without much consideration for Chinese content layout. Main Text About half a month ago, I adjusted the blog’s stylesheet – as I’ve been developing backend services for many years, I’m a pure newbie in frontend. After struggling with it for half a day, the design wasn’t quite reasonable. Suddenly an idea struck me: I looked at the technical blogs I often read – infoq and OpenChina – and their layouts look really good.

Spent four hours on this, and when I saw the sentence, it was hilarious. How could it have taken so long? Finally looked at the time: three hours. This was the first draft of the year 2022, and it wasn’t complicated – exactly as the title said. (At that time, I was still quite young), I thought simply copying 作业 would be enough, putting

A pattern of disruption to test system stability. Main Text The domestic internet industry is always fond of playing with new things, often introducing terms that most people wouldn’t be able to guess what they are. After reading some articles, this definition specifically for the early stages of Chaos Engineering is relatively easy to accept: Early exploration of Chaos Engineering has actually been ongoing within the industry, previously existing under the guise of fault testing and disaster recovery exercises.
