const kms = new KMSClient(awsConfig);
const testKeyId = 'e67f95-4c047567-4-a0b7-62f7ce8ec8f48';
export default async function () {
// List the KMS keys the AWS authentication configuration
// gives us access to.
const keys = await kms.listKeys();
// If our test key does not exist, abort the execution.
if (keys.filter((b) => b.keyId === testKeyId).length == 0) {
exec.test.abort();
}
