有一些很好的工具。下面是一些Java的摘要。

一些好的静态分析工具包括FindBugs(提供了一些有用的提示)、JLint、Java Pathfinder (JPF & JPF2)和Bogor。

multithreaddtc是一个非常好的动态分析工具(集成到JUnit中)，您必须在其中设置自己的测试用例。

IBM研究院的竞赛很有趣。它通过插入各种线程修改行为(例如sleep & yield)来检测你的代码，试图随机发现错误。

SPIN是对Java(和其他)组件建模的一个非常酷的工具，但是您需要一些有用的框架。它很难使用，但如果你知道如何使用它，它是非常强大的。相当多的工具在底层使用SPIN。

multithreaddtc可能是最主流的，但是上面列出的一些静态分析工具绝对值得一看。

Pete Goodliffe有一个关于线程代码单元测试的系列。

是很困难的。我采用了更简单的方法，尽量将线程代码从实际测试中抽象出来。皮特确实提到了我分手的方式是错误的但我要么是正确的，要么就是我很幸运。

上周我花了大部分时间在大学图书馆学习并发代码的调试。核心问题是并发代码是不确定的。通常，学术调试可以分为三个阵营之一:

Event-trace/replay. This requires an event monitor and then reviewing the events that were sent. In a UT framework, this would involve manually sending the events as part of a test, and then doing post-mortem reviews. Scriptable. This is where you interact with the running code with a set of triggers. "On x > foo, baz()". This could be interpreted into a UT framework where you have a run-time system triggering a given test on a certain condition. Interactive. This obviously won't work in an automatic testing situation. ;)

现在，正如上面评论者所注意到的，您可以将并发系统设计成更确定的状态。然而，如果你做得不好，你就又回到了设计顺序系统的问题上。

我的建议是，专注于制定一个非常严格的设计协议，规定什么是线程，什么不是线程。如果你限制了你的接口，使元素之间的依赖最小化，那就容易多了。

祝你好运，继续解决这个问题。

等待在帮助您编写确定性单元测试时也很有用。它允许您等待系统中的某个状态更新。例如:

await().untilCall( to(myService).myMethod(), greaterThan(3) );

or

await().atMost(5,SECONDS).until(fieldIn(myObject).ofType(int.class), equalTo(1));

它还支持Scala和Groovy。

await until { something() > 4 } // Scala example

测试线程代码和非常复杂的系统的另一种方法是通过模糊测试。 它不是很好，也不能找到所有的东西，但它可能是有用的，而且操作简单。

Fuzz testing or fuzzing is a software testing technique that provides random data("fuzz") to the inputs of a program. If the program fails (for example, by crashing, or by failing built-in code assertions), the defects can be noted. The great advantage of fuzz testing is that the test design is extremely simple, and free of preconceptions about system behavior. ... Fuzz testing is often used in large software development projects that employ black box testing. These projects usually have a budget to develop test tools, and fuzz testing is one of the techniques which offers a high benefit to cost ratio. ... However, fuzz testing is not a substitute for exhaustive testing or formal methods: it can only provide a random sample of the system's behavior, and in many cases passing a fuzz test may only demonstrate that a piece of software handles exceptions without crashing, rather than behaving correctly. Thus, fuzz testing can only be regarded as a bug-finding tool rather than an assurance of quality.

您可以使用EasyMock。使测试实例线程安全
