This year's spring recruitment has basically entered the large-scale lottery season, and many friends have achieved good results and got their favorite offers.
In major forums and communities, many small partners have generously shared common interview questions and stereotyped essays. For this reason, we will also organize and classify them here, which is also a key point.

Eight, Selenium-related
什么是 Selenium？
-
Selenium is a suite of tools dedicated to automating web browsers. That's all! What you do with this thing is entirely up to you. Primarily used for automated web application testing, but certainly not limited to that. Boring web-based administrative tasks can (and should!) be automated too.
Selenium has the support of some of the largest browser vendors who have taken (or are taking) steps to make Selenium a native part of their browsers. It's also the core technology behind countless other browser automation tools, APIs, and frameworks.
The latest Selenium version is already 3.0 (officially released on October 13, 2016), but because it is a new technology, Selenium 3.0 is not widely used. The range of changes is not very large, mainly because it is more inclined to Webdriver, and more abandoned RC.

9. Performance test
你认为性能测试的目的是什么？做好性能测试的工作的关键是什么？
-
The purpose of performance testing is to check whether the system meets the performance specified in the requirements specification. Performance testing often needs to be combined with strength testing, and often requires simultaneous testing of software and hardware.
The main focus of performance testing is response time, throughput, occupied memory size (auxiliary storage area), processing accuracy, etc.
简述什么是值传递，什么是地址传递，两者区别是什么？
- Transfer by value What the calling function passes to the called function is a copy of the value, not the original value; passing by address What the calling function passes to the called function is the address of the value. The difference is that the value transfer operation in the called function does not change the value of the calling function, but the address transfer is different.
