TLS

Zeebe supports TLS connection between the client and Zeebe itself: https://docs.camunda.io/docs/self-managed/zeebe-deployment/security/secure-client-communication/

The tests will test TLS and non-TLS connections. Therefore a cert and a private key needs to be created.

Generate cert

For the test there is a predefined cert and key with a validity of 10 years. The cert was generated with the following command:

cd tests/certification/bindings/zeebe/certs
openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -sha256 -days 3650 --nodes --addext 'subjectAltName=IP:127.0.0.1, DNS:localhost'

Automatic cert generation

There was also an attempt to generate the cert for each test automatically. The problem is that when using the automatic generated cert, the connection could not be established because of the following error:

transport: authentication handshake failed: EOF

The code that was used:

func CreateKeyAndCert(ctx flow.Context) error {
	keyFile, err := os.Create(TlsKeyFile)
	if err != nil {
		return err
	}
	defer keyFile.Close()

	certFile, err := os.Create(TlsCertFile)
	if err != nil {
		return err
	}
	defer certFile.Close()

	return nil

BPMN process files

The test suite uses two BPMN processes which are located in the processes folder. These processes can be edited with the Camunda Modeler

Missing tests

Incident related tests

Currently it's not possible to get an incident key which is needed to resolve an incident.
