为什么我的示例没有显示在GoDoc中？

I created a package with examples in the _test.go file and it worked fine. I moved the examples to integration_test.go then example_test.go and now they don't show up in my godoc

The contents of example_test.go is like so:

//+build integration

package gokini

import (
    "fmt"
    "time"
)

type PrintRecordConsumer struct {
    shardID string
}

func ExampleRecordConsumer() {
    // SNIP

    // Output:
    // Checkpointer initializing
    // foo
    // PrintRecordConsumer Shutdown
}
