error-checking code

基本解释

It's always important to add lots of error-checking code to test automation—after all, you're expecting to find errors.
有必要向测试自动化添加许多错误检查代码 — 毕竟您期待的是发现错误。
Assign code to regions that are hidden or exposed, depending on the detail of the view (for example, you can hide error-checking code when you want to analyze just the algorithm).
为隐藏或对外暴露的区域分配代码，这取决于视图的详细程度（例如，在只分析算法时，就可以隐藏错误检查代码）。
With the simple error-checking code in place and the Pango layout updated, the text will be positioned however specified on the command line, using the specified size, color, and fading parameters.
