Go Wrapper for using localstack in go testing
Installation
Please make sure that you have Docker installed.
go get github.com/elgohr/go-localstack
Usage
With SDK V2
func ExampleLocalstackWithContextSdkV2() {
ctx, cancel := context.WithTimeout(context.Background(), 20*time.Second)
defer cancel()
l, err := localstack.NewInstance()
if err != nil {
log.Fatalf("Could not connect to Docker %v", err)
}
if err := l.StartWithContext(ctx); err != nil {
log.Fatalf("Could not start localstack %v", err)
}
cfg, err := config.LoadDefaultConfig(ctx,
config.WithRegion("us-east-1"),
config.WithEndpointResolverWithOptions(aws.EndpointResolverWithOptionsFunc(func(_, _ string, _ ...interface{}) (aws.Endpoint, error) {
return aws.Endpoint{
PartitionID: "aws",
URL: l.EndpointV2(localstack.SQS),
SigningRegion: "us-east-1",
HostnameImmutable: true,
}, nil
})),
config.WithCredentialsProvider(credentials.NewStaticCredentialsProvider("dummy", "dummy", "dummy")),
)
if err != nil {
log.Fatalf("Could not get config %v", err)
}
myTestWithV2(cfg)
}
With SDK V1
func TestWithLocalStack(t *testing.T) {
ctx, cancel := context.WithTimeout(context.Background(), 20*time.Second)
defer cancel()
l, err := localstack.NewInstance()
if err != nil {
log.Fatalf("Could not connect to Docker %v", err)
}
if err := l.StartWithContext(ctx); err != nil {
log.Fatalf("Could not start localstack %v", err)
}
myTestWith(&aws.Config{
Credentials: credentials.NewStaticCredentials("not", "empty", ""),
DisableSSL: aws.Bool(true),
Region: aws.String(endpoints.UsWest1RegionID),
Endpoint: aws.String(l.Endpoint(localstack.SQS)),
})
}
