Detailed Description

Enumeration Type Documentation

◆ BreakCondition

enum OpenTap.BreakCondition

Test step break conditions. Can be used to define when a test step should issue a break due to it's own verdict.

Enumerator
Inherit	Inherit behavior from parent or engine settings.
BreakOnError	If a step completes with verdict 'Error', stop execution of any subsequent steps at this level, and return control to the parent step.
BreakOnFail	If a step completes with verdict 'Fail', stop execution of any subsequent steps at this level, and return control to the parent step.
BreakOnInconclusive	If a step completes with verdict 'Inconclusive', stop execution of any subsequent steps at this level, and return control to the parent step.
BreakOnPass	If a step completes with verdict 'Pass', stop execution of any subsequent steps at this level, and return control to the parent step.

◆ ComparisonOperator

enum OpenTap.ComparisonOperator

The operation for SearchParameterValue.

Enumerator
Equal	Two specified values must be the same.
NotEqual	Two specified values must be different.
Less	Parameter must be less than.
LessEqual	Parameter must be less than or equal.
Greater	Parameter must be greater than.
GreaterEqual	Parameter must be greater than or equal.
Like	Parameter must be similar to the value. This is guaranteed to be true if the two values are equal, but is not otherwise guaranteed to work in any specific way.
Exists	Value must exist as a parameter name or value.

◆ FormatVerbosities

enum OpenTap.FormatVerbosities

Indicates to what extend a formatter should be verbose.

Enumerator
SuperBrief	For the unit minutes, a formatter would just return ":".
Brief	For the unit seconds, a formatter would return "s".
Normal	For the unit seconds, a formatter would return "sec".
Verbose	For the unit seconds, a formatter would return "second".

◆ LayoutMode

enum OpenTap.LayoutMode

The supported layout modes.

Enumerator
Normal	The default mode.
FullRow	The user input fills the whole row.
FloatBottom	The user input floats to the bottom.

◆ LogEventType

enum OpenTap.LogEventType

Identifies the type of event that is logged.

Enumerator
Error	Recoverable error.
Warning	Noncritical problem.
Information	Informational message.
Debug	Debugging trace.

◆ LogicalOperator

enum OpenTap.LogicalOperator

Operation for SearchCombinator.

Enumerator
And	Specifies that both conditions must be satisfied.
Or	Specifies that at least one of the two conditions must be satisfied.

◆ OutputAvailability

enum OpenTap.OutputAvailability

Used to specify when an output value is available.

Enumerator
BeforeRun	The output value is available before the step has run. This can also be interpreted as always available.
AfterRun	After this step is completed. This may occur before or after AfterChildDefer.
AfterDefer	After defer of this step. This is the default for Outputs. This occurs after 'AfterChildDefer' and 'AfterRun'.

◆ ResourceOpenBehavior

enum OpenTap.ResourceOpenBehavior

Indicates how a IResource property should be handled when being opened or closed.

Enumerator

Before

The resources pointed to by this property will be opened in sequence, so any referenced resources are open before Open() and until after Close().

This is the default behavior

InParallel

Indicates that a resource property on a resource can be opened in parallel with the resource itself.

Ignore

Do not try to open the resource referenced by this property.

◆ ScpiIOResult

enum OpenTap.ScpiIOResult

Error codes from the IScpiIO methods

Enumerator
Success	Indicates successful completion.
Success_MaxCount	Indicates successful completion because the requested amount of bytes were read/written.
Success_TermChar	Indicates successful completion because a terminating character was found.
Error_General	General unspecified error.
Error_ResourceLocked	The call failed due to another client having a lock on the instrument.
Error_Timeout	Indicates that the call timed out.
Error_ConnectionLost	Indicates that the connection to the instrument was lost.
Error_ResourceNotFound	The resource could not be found.

◆ ScpiLockType

enum OpenTap.ScpiLockType

Types of VISA locks.

Enumerator
Exclusive	Indicates that the client should get an exclusive lock.
Shared	Indicates that a client should get a shared lock.

◆ SessionOptions

enum OpenTap.SessionOptions

Options used to define the behavior of a OpenTap.Session

Enumerator
None	No special behavior is applied. Starting a session like this, is the same as just starting a TapThread.
OverlayComponentSettings	Component settings are cloned for the sake of this session. Instrument, DUT etc instances are cloned. When this is used, test plans should be reloaded in the new context. This causes resources to be serialized.
RedirectLogging	Log messages written in Sessions that redirect logging only go to LogListeners that are added in that session.

◆ StepState

enum OpenTap.StepState

An enum containing the execution states of a step.

Enumerator
Idle	The step is not running.
PrePlanRun	The step is executing its PrePlanRun code.
Running	The step is executing its Run code.
Deferred	The step is executing deferred actions after Run.
PostPlanRun	The step is executing its PostPlanRun code.

◆ TapThreadStatus

enum OpenTap.TapThreadStatus

Status of a TapThread.

Enumerator
Queued	Work has been queued, but not started yet.
Running	Work is currently being processed.
Completed	Work has completed.
HierarchyCompleted	This and all child threads have completed.

◆ TestPlanExecutionStage

enum OpenTap.TestPlanExecutionStage

This indicates what stage a testplan execution is at.

Enumerator
Open	Indicates that a testplan is being opened.
Execute	Indicates that a testplan is starting to execute. Implies that the testplan already is open.
PrePlanRun	Indicates that a teststep is about to run it's PrePlanRun.
Run	Indicates that a teststep is about to be run.
PostPlanRun	Indicates that a teststep is about to run it's PostPlanRun.

◆ TestStepSearch

enum OpenTap.TestStepSearch

Search pattern to use while getting child steps.

Enumerator
All	All steps are wanted.
EnabledOnly	Only enabled steps are wanted.
NotEnabledOnly	Only disabled steps are wanted.

◆ Verdict

enum OpenTap.Verdict : int

Enumeration containing the verdict types used for TestRun.Verdict and TestRun.Verdict properties.

Enumerator
NotSet	No verdict has been set. This is the default value.
Pass	Test passed.
Inconclusive	Test had an inconclusive result.
Fail	Test failed.
Aborted	Test was aborted.
Error	Test failed due to an exception or another procedural error. Such as no instrument/DUT connection.
