This test suite is used to verify a telematic infrastructure (TI) product server of the German health care system against gematik gemSpec_PKI specifications available at gematik Fachportal. Especially TUC_PKI_001 (TSL validation), TUC_PKI_018 (certificate validation) and TUC_PKI_006 (OCSP response validation). It is used for approval tests of every PKI related aspect. It is a re-development of our test suite from 2016.
Products tested by this test suite are: Intermediär, VSDM Fachdienst, VPN Zugangsdienst: Registrierungsdienst and Konzentrator, IDP Fachdienst, IDP eGK Fachdienst, KIM Fachdienst. More are coming.

# Test artefacts (i.e. logs and report) can be found in ./out directory.The test suite consists of four parts necessary for validating a PKI test object. These are implemented as maven modules and can be used independently or in conjunction with the test suite.
To execute the test suite, you need at least Java 17. The test suite ist build and testet with Eclipse Adoptium Temurin JDK 17
This is the test suite itself. It is used to start all following modules, configure them and read the results. It has a package with classes to all approval tests. The test suite calls a use case (see Use Case Modules) and expects it to either pass or fail, depending on the test data used. If the expectation is fulfilled, the test case is passed.
The test suite has a couple of convenience options:
java -jar ./bin/pkits-testsuite-exec.jar --helpUsage: <main class> [-h] [-np] [-faf=<failedTestCases>] [-p=NUMBER]
[-tf=<testCasesFile>] [-tn=<testCasesNames>]
-faf, --failed-and-aborted-file=<failedTestCases>
Save all failed or aborted tests to this file. The
file can be used as parameter for theCLI option
--tests-file.
Default: ./allFailedOrAborted.txt
-h, --help Display this help message.
-np, --no-pdf-report Do not generate report as PDF.
-tf, --tests-file=<testCasesFile>
The file with tests to run.
Default: ./allTests.txt
-tn, --tests-names=<testCasesNames>
Comma separated list of names to run, for example:
"verifyUseCaseCertsValid, TslApprovalTestsIT,
TslSignerApprovalTestsIT#checkInitialState".
The TSL provider is a service that delivers TSLs to the test object. The behavior of this service, such as the content of a TSL offered to the test object, is configured automatically during the test execution over a REST interface. The TSL provider is implemented as a spring boot tomcat web server and runs as its own process.
The socket that is runs on is configured as followed:
tslProvider:
ipAddressOrFqdn: "127.0.0.1"
port: 8084This configuration is also written to every tsl as the download points in PointersToOtherTSL. For
this reason, it is crucial to configure it correctly before generating the initial TSL for the test
object (see Initial TSL and Trust Anchor).
The TSL provider is started automatically at the configured socket, but it can be started
independently. To do so, one has to set appPath to "externalStartup" in the pkits.yml. Address
and port can be passed to the jar via --server.port=[port]
and --server.address=[ipAddressOrFqdn]. This way it is possible to run the TSL provider in a
different environment as the test suite.
The TSL provider has an open-api interface for documentation at <socket>/api-docs.
The OCSP responder is a service to generate responses to OCSP requests sent by the test object. The behavior of this service is configured over a REST interface and transparent to the user. Depending on the tests, the test suite configures it to deliver unsigned OCSP responses, wrong cert hashes, and so on. Similar to the TSL provider, it is implemented as a spring boot tomcat web server and runs as its own process.
The socket that is runs on is configured as followed:
ocspResponder:
ipAddressOrFqdn: "127.0.0.1"
port: 8083This configuration is also written to every tsl as the service supply point of each trust service. For this reason, it is crucial to configure it correctly before generating the initial TSL for the test object (see Initial TSL and Trust Anchor).
The OCSP responder is started automatically at the configured socket, but in can be started
independently. To do so, one has to set appPath to "externalStartup" in the pkits.yml. Address
and port can be passed to the jar via --server.port=[port]
and --server.address=[ipAddressOrFqdn]. This way it is possible to run the OCSP responder in a
different environment as the test suite.
Example scripts on how to run the OCSP responder independently for other tasks can be found in the
documentation directory: ocspResponderExample or via the open-api
interface: <socket>/api-docs.
At the moment, there are two ways of communicating with a test object. In all scenarios, the test object has to be a server. This means the PKI test suite acts like a client during PKI tests.
For test objects that are more or less a TLS Server, a TSL client implementation is bundled with the
test suite. It establishes a TLS handshake to a test object with a given certificate
(see configuration).
Corresponding to AFOs: GS-A_4385-01 and A_17127-01 the TLS handshake will follow the
specifications from gemSpec_Krypt with the following parameters:
- TLS Version: 1.2
- cipher suites used: TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384 or TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256
- for the test of RSA functionality, we use the following cipher suites: TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 and TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
- for ECDHE either NIST P-256 or P-384 is used
A script (shell, batch or other executable program) is started as an own process. A script
can be written from every PKI test suite user to communicate with a test object. The test suite
passes two parameters as command line arguments to any call: pathToCertificate
and certificatePassword in this order.
Be sure to return exit code "0" if the communication was successful and "1" if it was not. Be
careful about the exit code. Thr script solely should only return "0" if the use case was
successful, not if the script could be executed successful!
It is possible to execute a script remotely over ssh. See sshConfig section in the configuration
file. You have to configure the authentication (password or certificate), files that have to be
copied to the remote location and back. As wells as the IP and port of the remote machine.
The configuration is done in one file: /config/pkits.yml. You can find
examples in /docs/config/inttest/. The most important parameters are:
- What is the type of the test object (e.g., KimFachdienst, IntermediaerServer, etc.)?
- How to reach the test object (i.e., ipAddress and port)?
Example:
testObject:
name: "Server 0815"
testObjectType: "IntermediaerServer"
ipAddressOrFqdn: "127.0.0.1"
port: 8443Furthermore, the test object must be able to reach the TSL- and OCSP-simulators provided by this test suite.
Paths in the pkits.yml are relative to the base directory. Absolute paths can be used as well.
All available parameters including a short description can be found
in all_pkits_parameters.yml. As this is a YAML file remember to
strictly follow the syntax.
Remember: A change of parameters that will change the TSL (i.e. OCSP responder address and port or
TSL provider address an port) require a new generation of the initial TSL and import to the test
object.
The TLS-Client used by the testsuite to connect to the testobject supports SNI. SNI is enabled by default in: pkits-tls-client/src/main/resources/config.yml.
We deliver some test data in the directory ./testDataTemplates. Currently, these test data support
tests for the following TI products:
| Test object | testObjectType in pkits.yml | Test data directory |
|---|---|---|
| KIM Fachdienst | KimFachdienst | kimClientModul |
| VPN-ZugD Konzentrator | VpnKonzentrator | netzkonnektorClient |
| VPN-ZugD RegServer | VpnRegServer | fachmodulClient |
| VSDM Fachdienst | VsdmFachdienst | intermediaerClient |
| VSDM Intermediär Server | IntermediaerServer | fachmodulClientIntermediaer |
| Zentraler/SmartCard IDP | IdpFachdienst | fachmodulClient |
| Zentraler IDP | IdpEgkFachdienst | egkClient |
These test data are for our own integration tests and can be used for approval tests as well. The test data form an own PKI, hence it is not easy to create them by yourself. If you use your own test data, make sure that issuing certificates are added in the tsl template as well.
The TSLs are generated depending on the parameter tslCryptType in pkits.yml, which can have the values "RSA-ECC" and "ECC-Only". The default value is "RSA-ECC". If tslCryptType is set to ECC-Only, a separate tsl template with only ECC certificates is used for TSL generation.
For the configuration of the test object, it is necessary to initialize it with a trust space
compatible with the test suite.
For this, a convenient script is provided by the test suite:
By executing ./initialTslAndTa.sh an initial TSL and the corresponding trust anchor are written to
the ./out directory for manual import into the test object.
Before generating this TSL, it is crucial to configure the sockets for the TSL provider and OCSP responder correctly.
This TSL contains the TU trust store as well; this means that the test object can be used during the pki tests by other services as well.
The test suite expects a test object that is running and accessible over the configured IP address
and port (see Configuration). Tests are executed via the
script ./startApprovalTest.sh.
Furthermore, the OCSP responder
and TSL provider communicate at the configured sockets (if they are
not deactivated). Logs are written to the ./out/logs directory. Afterward a test report is
generated in the ./out/testreport directory.
To make a quick check if everything is set up correctly, the test object can be reach by
the test suite, and to initialize the test suite with the TSL sequence number set in the test
object; we implemented a script that runs an initial test: ./checkInitialState.sh.
Within a TSL download by the test object is expected, and afterward, a use case is triggered with a
valid certificate.
OCSP requests are expected and answered correctly as well.
Therefore, a configured test object has to be up and running and accessible by the testsuite and its
components.
Besides executing all tests, it is possible to select or exclude specific tests for execution.
This is done via the file allTests.txt.
The file lists test classes CertificateApprovalTests, OcspApprovalTests,
TslApprovalTests, TslITSignerApprovalTests, TslTaApprovalTests and all tests defined in
the test classes.
Test classes as well as separate tests can be marked with + or -.
Tests marked with a + will be executed when ./startApprovalTests.sh is used the next time.
Tests marked with a - are excluded from the execution.
If a test class is marked with + then all tests of the test class are selected for execution,
except those marked with -.
Inversely, if a test class is marked with - then all tests of the test class are excluded from
execution, except those marked with +.
All failed or aborted tests are saved into file ./allFailedOrAborted.txt (default name).
This file then can be used to run all or selected of the failed or aborted tests.
Run java -jar ./bin/pkits-testsuite-exec.jar --help for more information.
Our concept of testing incorporates the following principles:
- An OCSP responder is simulated and the test object is configured to use this instead (over the TSL).
- A TSL provider is simulated and the test object is configured to use this instead (over the TSL).
- A use case is triggered that provokes the check of an end-entity certificate.
Both simulators are configured for each test case and each used certificate individually and reset afterward. This means that only during the test execution, the simulators answer requests with a useful response. In between tests, requests are answered with a http 500 error code.
Every request the test object does to one of the simulators contains the sequence number of the last correctly processed TSL. This serves as a check to evaluate the trust store in the test object.
Mainly, we use two different kinds of test data
- A default end-entity certificate to trigger a use case for the corresponding test object (e.g., a TLS handshake) signed by a SUB-CA.
- An alternative end-entity certificate signed by another SUB-CA. This alternative SUB-CA certificate is not every time in the TSL.
This way it can be checked if the trust store changed, and if a TSL was processed as expected.
Every test is independent and all tests can be executed in any order. However, there is one test
that is expected to disable the PKI functionality of the test object by importing a TSL which
expires a few moments after generation: verifyExpiredTslInSystem(). This is why the test suite
executes this test case always at the end.
It is possible to containerize the components of the test suite (OCSP Responder, TSL Provider). You can start them localy as docker compose services. See these configuration files:
The following scripts from directory ./docs/docker/ can be used to build, run and use the container images:
Docker-Desktop 4.21.1 (with Docker Engine 24.0.2 and Docker Compose: v2.19.1) was used for testing this functionality.
Make sure that your particular configuration file (pkits.yml) is used by the docker3_RunTests.sh
script.
Building the project requires at least Java 17, Apache Maven 3.6.3 and a local or online accessible Maven Central cache.
The following commands will build the sources and generate a zip package like the one from the release.
mvn clean package You can find the zip package in the directory ./out/pki-testsuite-x.x.x.zip.
