MStest加载时间太长

Question

我有一个使用MSTests的项目设置，但是它们甚至加载我的项目特定的DLL之前，都花费太长时间来加载所有测试DLL。

我在使用Resharper 10.0.1的Visual Studio Professional 2015中

由于堆栈溢出有关限制的投诉，我在这里仅附加部分日志，但是遵循这些dll的同一行，它的大小会增加10倍。 在我的dll开始加载之前，总时间大约为30秒，但之后只有几秒钟可以接受。

有什么可以优化的吗？

实际上，发现某些库在不同的“域”下被多次加载/卸载（到目前为止，我不知道其含义是什么）

我上面描述的模式发生了很多次。 在我发现138个匹配项的日志中搜索mscorlib.dll ！！

我的直觉是这是原因，但是我仍然不知道解决方案的线索

谢谢

Answer 1

实际上，经过一番研究，我发现罪魁祸首是使用TestSettings1.testsettings而不是test.runsettings。

经过一段时间的调整（主要是由于缺少Global DeploymentItems，我使用基类解决了），这些测试现在可以在10秒以内运行，这是更好的选择。

认为虽然仍有改进的空间，但至少我现在对此感到满意
