How to test a collection of functions by reflection in Go?

I have to write unit tests for several functions with similar signature and return values (an object and an error), which must pass similar test conditions.
I would like to avoid writing:

func TestFunc1(t *testing.T) {
    // tests on return values
}
func TestFunc2(t *testing.T) {
    // tests identical for Func1
}
func TestFunc3(t *testing.T) {
    // tests identical for Func1
}
...

(See this go playground example for a more complete context)
(yes, go playground doesn't support yet go test, only go run, and issue 6511 is there to request that feature)

How would you use reflection (reflect package) in order to write only one test which would:

• call each function in turn?
• test their return value?

I have seen:

• "How to properly use .Call in reflect package, Golang?", using Value.Call
• "Selecting a function from a list of functions in Golang"

But I miss a complete example for calling functions and using the returned values in a test.
