英文:
$GOPATH/src/... and vendor/... versions are different
问题
我的项目使用Go 1.8，并且依赖于github.com/stretchr/testify。我使用go get -u github.com/stretchr/testify命令获取了最新版本，并且在$GOPATH/src目录下的版本看起来是正确的。
我在Gopkg.toml文件中添加了最新版本号的约束：
[[constraint]]
name = "github.com/stretchr/testify"
version = "1.1.4"
然后我运行了dep ensure -update命令，然后运行了dep status命令来更新vendor目录（dep status的输出结果）：
github.com/stretchr/testify ^1.1.4 v1.1.4 69483b4 69483b4 1
在$GOPATH/src目录下的版本中，文件github.com/stretchr/testify/assert/assertions.go中包含了函数PanicsWithValue：
func Panics(t TestingT, f PanicTestFunc, msgAndArgs ...interface{}) bool {
// ...
}
func PanicsWithValue(t TestingT, expected interface{}, f PanicTestFunc, msgAndArgs ...interface{}) bool {
// ...
}
func NotPanics(t TestingT, f PanicTestFunc, msgAndArgs ...interface{}) bool {
// ...
}
但是在vendor目录下的版本中，这个函数缺失了：
func Panics(t TestingT, f PanicTestFunc, msgAndArgs ...interface{}) bool {
// ...
}
func NotPanics(t TestingT, f PanicTestFunc, msgAndArgs ...interface{}) bool {
// ...
}
我做错了什么？我想在我的测试中使用PanicsWithValue函数。我甚至尝试删除整个vendor目录并重新构建，但问题仍然存在。
英文:
My project, using Go 1.8, has a dependency on github.com/stretchr/testify. I retrieved the latest using go get -u github.com/stretchr/testify and the version in $GOPATH/src appears to be correct.
I added the latest version number as a contraint in Gopkg.toml:
[[constraint]]
name = "github.com/stretchr/testify"
version = "1.1.4"
I then ran dep ensure -update and then dep status to update the vendor directory (output of dep status):
github.com/stretchr/testify ^1.1.4 v1.1.4 69483b4 69483b4 1
The version in $GOPATH/src contains, in the file github.com/stretchr/testify/assert/assertions.go, the function PanicsWithValue:
func Panics(t TestingT, f PanicTestFunc, msgAndArgs ...interface{}) bool {
// ...
}
func PanicsWithValue(t TestingT, expected interface{}, f PanicTestFunc, msgAndArgs ...interface{}) bool {
// ...
}
func NotPanics(t TestingT, f PanicTestFunc, msgAndArgs ...interface{}) bool {
// ...
}
but in the version in vendor, that function is missing:
func Panics(t TestingT, f PanicTestFunc, msgAndArgs ...interface{}) bool {
// ...
}
func NotPanics(t TestingT, f PanicTestFunc, msgAndArgs ...interface{}) bool {
// ...
}
What am I doing wrong? I would like to use the function PanicsWithValue in my testing. I even tried deleting the entire vendor directory and rebuilding it.

通过将版本固定为v1.1.4，你明确告诉dep使用不包含你想要的功能的版本（在GitHub上检查testify包的历史记录 - v1.1.4是去年9月的版本，PanicsWithValue是在今年6月添加的）。如果你取消固定版本（version = "*"），它应该使用包含PanicsWithValue的master@HEAD版本。
英文:
By pinning the version to v1.1.4, you're specifically telling dep to use a version that does not include the feature you want (check the history of the testify package on GitHub - v1.1.4 is from last September, PanicsWithValue was added this past June). If you unpin the version (version = "*") it should use master@HEAD which includes PanicsWithValue.
