You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: minikube.go
    path of file: ./repos/terratest/modules/k8s
    
    the code of the file until where you have to start completion: package k8s

import (
	"strings"

	"github.com/gruntwork-io/terratest/modules/testing"
	corev1 "k8s.io/api/core/v1"
)

// IsMinikubeE returns true if th
    
func IsMinikubeE(t testing.TestingT, options *KubectlOptions) (bool, error) {
	nodes, err := GetNodesE(t, options)
	if err != nil {
		return false, err
	}

	// ASSUMPTION: All minikube setups will have nodes with labels that are namespaced with minikube.k8s.io
	for _, node := range nodes {
		if !nodeHasMinikubeLabel(node) {
			return false, nil
		}
	}

	// At this point we know that all the nodes in the cluster has the minikube label, so we return true.
	return true, nil
}
