Be Careful with Table Driven Tests and t.Parallel()

Be Careful with Table Driven Tests and t.Parallel()

We Gophers, love table-driven-tests, it makes our unittesting structured, and makes it easy to add different test cases with ease.

Let’s create our table driven test, for convenience, I chose to use t.Log as the test function. Notice that we don't have any assertion in this test, it is not needed to for the demonstration.

func TestTLog(t *testing.T) {
	t.Parallel()

cgo convert list

See also, http://libraryofalexandria.io/cgo/

Using Go cgo

cgo has a lot of trap.
but Not "C" pkg also directory in $GOROOT/src. IDE's(vim) Goto command not works.

So, Here collect materials.

#####希望转载的朋友,你可以不用联系我.但是一定要保留原文链接,因为这个项目还在继续也在不定期更新.希望看到文章的朋友能够学到更多.

介绍:这是一篇介绍在动态网络里面实现分布式系统重构的paper.论文的作者(导师)是MIT读博的时候是做分布式系统的研究的,现在在NUS带学生,不仅仅是分布式系统,还有无线网络.如果感兴趣可以去他的主页了解.

Go RPC over TLS.You have to create the following keys: certs/client.crt, certs/client.key, certs/server.crt, certs/server.key. client.crt and server.crt should be signed with ca.crt, which should be concatenated to both client.crt and server.crt. It's easier to do with easy-rsa: http://openvpn.net/index.php/open-source/documentation/howto.html#pki
