Type:

list

ClearSignalCache()¶

Removes all signals from the signal cache.

Info

Calling this method can be useful in large projects analyzing many object signals (signals that are not of a primitive data type). Object signals are cached in memory. Thus, if the analyses of the project access different object signals, the memory consumption is continuously increasing. Calling this method frees all the memory consumed by the signal cache.

This method should be called at some point in the project, when it is known that most of the previously used signals are not required anymore for the following analyses or if the memory consumption has to be reduced. Calling this method too often, has a negative effect on the execution time.

In order to ensure that the signal cache is cleared completely, this method should be called in a separate episode or the test case part of a package.

AnalysisExecutionInfo¶

class AnalysisExecutionInfo¶

Multimedia¶

Entry point in the internal api for multimedia content

class ImageFiltersApi¶

Provides access to image filters. Filters are grouped into the two namespaces default and user. The following filters are provided by ecu.test out of the box:

• default.BlurFilter(image, Type='GAUSS', Kernelsize=15)

• default.BWFilter(image, Threshold=-1)

• default.ColorFilter(image, Colors=["#ff0000"], Tolerance=5)

• default.ContrastFilter(image, Contrast=1, Brightness=0)

• default.HSVFilter(image, Hue=0, Saturation=1, Value=1)

• default.InvertFilter(image)

• default.RotationFilter(image, Angle=90)

To call a filter you can pass an image object as first argument, followed by any parameter the filter expects. Note that the filter parameters must be passed as keyword arguments. They cannot be passed as positional arguments. If a parameter is omitted it will be filled with its default value. For example to increase the brightness of an image:

>>> filteredImage = api.Multimedia.ImageFilters.default.ContrastFilter(image, Brightness=100)

Any user-defined image filter will appear under the namespace user. Suppose you implemented a custom filter and placed it in the UserPyModules directory. The filter could then be accessed via api.Multimedia.ImageFilters.user.MyCustomFilter.

Note that all filters will show up in a flat list without accounting for any file system hierarchies. For example a filter located at “UserPyModules/My Image Filters/MyCustomFilter.py” will still show up as user.MyCustomFilter. Therefore please make sure that your filters use unique module names in order to avoid name clashes.

Provides access to multimedia content at runtime

Info

This is not the recommended way of changing the status of connected tools. Instead, a configuration change step in a project should be used.

Credentials API¶

Introduction¶

The credentials API can be used to manage and access credentials such as certificates and private keys.

Keystores¶

Certificates and private keys are stored in keystores, e.g. PKCS12 files. These keystores are meant to prevent direct access to especially private keys. For example, PKCS12 files can be encrypted by a password to protect the private key from simple plaintext access via the file system.

Managing Keystores¶

Keystores can be created or loaded in the central vault of ecu.test to access them later within a test case, e.g. via path and the password of a PKCS12 file via CreatePkcs12KeyStore and LoadPkcs12KeyStore. The vault is encrypted and secured by a central password that must be provided by the user to decrypt and gain access to the saved keystores - similar to the concept of a password manager.

Accessing Keystores¶

Previously created or loaded keystores can be simply accessed as attribute or by GetVaultEntry:

>>> api.Credentials.OpenCryptFileVault(...)
>>> api.Credentials.CreatePkcs12KeyStore("myKeyStore", ...)
>>> ...
>>> api.Credentials.myKeyStore.GetPrivateKey()
>>> api.Credentials.GetVaultEntry("myKeyStore").GetCertificates()

Secrets¶

Simple secrets such as strings or byte streams can be stored directly in the vault. Analogously to keystores, they can be accessed as attribute or by GetVaultEntry:

>>> api.Credentials.OpenCryptFileVault(...)
>>> api.Credentials.CreateSecret("secret", "e25f790f00e553b82592626a2a948a64", "accessToken")
>>> ...
>>> api.Credentials.secret.Reveal()
'e25f790f00e553b82592626a2a948a64'
>>> api.Credentials.GetVaultEntry("secret").AssociatedData()
'accessToken'

Managing the Vault¶

Currently, the central vault is a password encrypted file containing the access data to the different keystores. One can simply create a vault by CreateCryptFileVault or load an existing one by OpenCryptFileVault.

Security¶

See security notes for the vault in the workspace settings documentation.

Examples¶

Creating a vault:

>>> api.Credentials.CreateCryptFileVault("C:/<path>/vault")
>>> api.Credentials.Close()

Creating a PKCS12 keystore:

>>> api.Credentials.OpenCryptFileVault("C:/<path>/vault")
>>> pkcs = "C:/<path>/service29.pkcs"
>>> privateKey = "C:/<path>/private.key"
>>> certs = ["C:/<path>/Service29.crt"]
>>> api.Credentials.CreatePkcs12KeyStore("service29", pkcs, privateKey, certs)
>>> api.Credentials.Save()
>>> api.Credentials.Close()

Accessing keystores:

>>> # Assuming the vault has been opened beforehand
>>> privateKey = api.Credentials.service29.GetPrivateKey()
>>> cert = api.Credentials.service29.GetCertificate("SERVICE-29")  # common name SERVICE-29
>>> signature = privateKey.Sign(ByteStream(b"message"))
>>> cert.Verify(signature, ByteStream(b"message"))
True
>>> cert.Verify(signature, ByteStream(b"nonsense"))
False
