I’m having a hard time figuring out why a function declared and defined in a certain _test.go like this:

file1_test.go:

//go:build foo_test_1

package foo

import (
    "testing"
    "reflect"
)

func generateNode() *Node {
    return &Node{}
}

// ... rest of file are just test funcs

inside another _test.go file:

//go:build foo_test_2

package foo

import "testing"

func TestXXX(t *testing.T) {
     n := generateNode{}
     // ... rest of the test logic
}

I’m using different build tags to filter tests to be executed.

Does the problem happen because I’m missing a concept for go builds in testing despite having the 2 test files in a single package?

Tree of the package:

.
├── file1.go
├── file1_test.go
├── file2.go
└── file2_test.go
