英文:
Assertion in non-test function in Go
问题
我想在一个函数中使用断言，但它不是一个测试函数，只是一个普通的函数。我想使用类似 assert.Equal(param1, some_constant) 的语法。我找到了这个包：https://godoc.org/github.com/stretchr/testify/assert
不过，它似乎也需要 testing 包，并且需要给函数传递一个类型为 *testing.T 的参数。在Go语言中是否有其他的断言函数，可以直接调用 assert 函数，而不依赖于任何其他的测试包或参数？
英文:
I want to use assertion in a function, but it is not a test function. It is just a normal function, and I want to use something like assert.Equal(param1, some_constant). I came across the following package: https://godoc.org/github.com/stretchr/testify/assert
Though, it appears that it also requires the testing package, and to give to a function a parameter of type *testing.T. Is there any other assert function in Go, where I can directly call the assert function without actually relying on any other testing package or parameter?

Go语言不提供断言（assertions）。Go团队在语言FAQ中有一个相关的部分，链接在这里：https://golang.org/doc/faq#assertions
如果你真的需要断言，你可以编写一个普通的函数，接受两个值，并根据它们是否相等来执行相应的操作。
英文:
Go does not provide assertions. There is a section in the language FAQ from the Go team here: https://golang.org/doc/faq#assertions
If you really into it, you can just write a normal function that accepts two values and does something if they evaluate to equal or not equal, as you desire.
