What is the most concise way of TDD an HashMap in Golang?

The following test code is able to test an HashMap in Golang. The question is whether this is the most concise way of TDD an HashMap in Golang.

import (
    "regexp"
    "testing"
)

func TestHashMap(t *testing.T) {
    for actualKey, actualValue := range hashMap() {
        expectedKey := "(hello|world)"
        matchedKeys, _ := regexp.MatchString(expectedKey, actualKey)

        expectedValue := "test"
        matchedValues, _ := regexp.MatchString(expectedValue, actualValue)

        if !matchedKeys {
            t.Errorf("Test failed, expected: '%s', got:  '%s'", expectedKey, actualKey)
        }

        if !matchedValues {
            t.Errorf("Test failed, expected: '%s', got:  '%s'", expectedValue, actualValue)
        }
    }
}
