Roslyn-动态（运行时）流程 [英] Roslyn - dynamic (runtime) flow

问题描述

我开始和罗斯林一起玩。解析代码和进行静态分析相对容易。

I started playing with Roslyn. It’s relatively easy to parse code and do static analysis.

我想知道是否可以将其用于运行时分析？我想调用带有参数的方法，并检查执行了哪些分支。换句话说，我需要一个运行时执行计划。
Roslyn可以解决吗？

I wonder if it’s possible to use it for runtime analysis? I want to call a method with parameters and check which branches were executed. In other words, I need a runtime execution plan. Is it something which could be done with Roslyn?

推荐答案

我不知道什么是最好的解决方案是，在大多数情况下，我会遵从SLaks的建议。

I don't know what the best solution is and I would defer to anything SLaks recommends in most cases.

但是...

如果您想和Roslyn一起做，那就一定可以。实际上，在我公司中，我们做了类似的事情（我们将单元测试映射到他们调用的方法）。

If you want to do this with Roslyn you certainly can. In fact at my company does something similar (we map unit tests to the methods they invoke).

以下是我们方法的高级概述。

Here's a high level overview of our approach.

1. 重写解决方案中的每个函数，以在某些全局静态查找/数据结构中被击中时进行记录。您可以一次遍历每个文件，并对每个文件使用 CSharpSyntaxRewriter 。 （在您的情况下，您将在分支或逐行的基础上进行重写）

1. Rewrite every single function in the solution to log when it is hit in some global static lookup/data-structure. You can iterate over every file one at a time and use the CSharpSyntaxRewriter on each one. (In your case you'll be rewriting on a branch or line-by-line basis)

一次运行每个单元测试，看看会得到什么

Run each unit test one at a time and see what gets run by analzying your global lookup.

汇总所有单元测试的结果以了解完整的代码覆盖范围。

Aggregate the results across all your unit tests to understand your complete code coverage.
