Default recording configuration¶

The Default recording configuration is an execution setting of the test configuration. It can be used to centrally define recording-related settings for test execution instead of repeating them in each package.

For better differentiation, the following terms are defined:

Default recording package: This package is part of the default recording configuration. Contents from the Signal recordings tab are taken into account.
Test case package: The specific package that implements a test case for which recordings shall be created.

The default recording package is a regular package specified in the test configuration. Signal groups and signals defined in this package are automatically used in test case packages. Whether a signal group, one of its settings, or other settings such as trace merge are used depends on a number of rules:

Use case 1: Recording on demand

If no suitable group is found in a package for signals from Signal group “Assign automatically” or via Record all test quantities, suitable groups are adopted from the default recording configuration.

Use case 2: Always record everything

If all groups and signals from the default recording package are to be transferred to the test case package, you can enable the TCF option Always use signal groups and signals in test case packages and stimulation package steps. This requires the test case package to be used as a stimulation package in a project or the test case flag (a property of the package) to be set.

Signal recordings tab¶

In the signal recordings tab, elements automatically imported from default groups are displayed by default, but can also be hidden. For details, see Creating signal groups and recording groups. Furthermore, the behavior when adding signals via drag-and-drop changes if a suitable default signal group exists in the loaded test configuration with the Default recording package: A new signal group is not automatically created; instead, the signal is added to the Assign Automatically group.

Feature table

The following table describes specific settings of the default recording package in more detail.

Feature overview and restrictions¶
Feature	Description
Signal groups	A signal group in the `default recording package` should have only one recording group. Default signal groups are adopted at runtime as complete signal groups together with their recording groups if they are needed for automatic assignment or if the TCF option Always use signal groups and signals in test case packages and stimulation package steps is enabled. If the `test case package` already contains a signal group with the same name, no second signal group is created.
Signals in signal groups	If the `test case package` already contains a signal group with the same name, missing signals from the default group are added. Locally existing signals remain unchanged. If there is a naming conflict with a different mapping target, adopted signals are renamed automatically; this renaming is also taken into account when synchronizations are adopted. A measurement list of the default group is used if the local group does not have its own measurement list.
Recording group settings	Recording group settings are not merged into local recording groups with the same name. They only apply if the corresponding default signal group is adopted as a whole; in that case, the recording groups of the `default recording package` are copied. Special attention must be paid to recording control. Either use Start/StopTrace test steps in the `test case package`, or use Auto-Start/Stop on the recording groups. This setting must be maintained consistently for both the `test case package` and the `default recording package`.
Assign automatically group	Signals from the `Assign automatically` group of the `test case package` take signal groups of the `test case package` and of the `default recording package` into account. If the assignment is ambiguous or impossible, the signal is not assigned automatically. The `Assign automatically` group of the `default recording package` is not supported yet.
Record all test quantities	If the setting is not enabled in the `test case package`, it is adopted from the `default recording package`.
Synchronization	If an active synchronization is configured in the `test case package`, its basic configuration remains authoritative; synchronizations from the `default recording package` are additionally adopted only if the participating recording groups are available at runtime. Dependency chains are resolved automatically, so both packages do not necessarily need to configure the same recording group as master. It is only important that a linear dependency graph can be derived for both packages via a shared recording group. If no local synchronization exists, the basic settings of the default configuration are adopted.
Trace merge	If the `test case package` has no active trace merge configured, the configuration from the `default recording package` is adopted.
Package variables	The `default recording package` must not contain package variables marked for recording. Likewise, the synchronization configured there must not use package variables. If one of these conditions is violated, the `default recording package` is discarded entirely and not applied. Other uses of variables, for example in the path of the trace merge, are valid and do not prevent the use of the `default recording package`.

Example overview

Detailed examples can be found on a dedicated subpage. That page describes typical usage scenarios including initial situation, configuration, runtime behavior, and recommendation.

The examples address the following topics in particular:

automatic assignment without a matching local signal group
extending a local signal group with the same name
adopting synchronizations from the default recording package
always recording a few signals
always recording many signals
