Step-based execution control¶
The default behavior in step-based scenarios is to run all steps in order, until one fails or until all the steps are done.
On failure, proceed with scenario¶
Some steps, among which the Build/train one, can treat errors as mere warnings. This means that if some error occurs during the execution of the step, which should normally stop the execution of the whole scenario, the error is downgraded to a warning and subsequent steps in the scenario are run.
An example is the Kill another scenario step: if a scenario A has a Kill another scenario step where it attempts to abort another scenario B, the run of scenario A will fail if scenario B has not started or has already finished running. It may then be useful to activate the Ignore failure on the Kill another scenario step so that scenario A can always run subsequent steps.
Run step conditionally¶
The behavior of step-based scenarios to stop at the first failing step can be overriden by using the Run this step options of each step.
Never¶
To disable a step, but keep it around, one should use the Never option
Always¶
The step is always run, regardless of whether previous steps failed or not. This is equivalent to a finally block. For example a step that frees computational resources taken before in the scenario need to run regardless of the state of the previous step, so that resources are properly freed.
If no prior step failed¶
This is the default behavior of steps.
If some prior step failed¶
This mode lets the user run steps only in case of a failure in the preceeding steps, like a catch clause. For example to deactivate a report or send a message if a build did not succeed.
If current outcome is¶
This mode is a more generic version of the above modes.
If condition satisfied¶
This mode is the most generic of all, and lets the user decide to run a step based on the current outcome of the scenario or on the value of variables set before in the scenario or in the project.
The expression is a formula. The variables available in the formula are:
outcome : the current outcome of the scenario; possible values are ‘SUCCESS’, ‘WARNING’, ‘FAILED’, ‘ABORTED’
stepOutcome_stepName : the outcome of the step named ‘stepName’, if the step defined one
stepResult_stepName : the result of the step named ‘stepName’, if the step defined one
stepOutput_stepName : the output of the step named ‘stepName’, if the step defined one
project-level variables, scenario-level variables
scenarioTriggerParams : the parameters of the trigger that initiated the scenario run, if the trigger defined some. If not empty, the fields of scenarioTriggerParams are also accessible as scenarioTriggerParam_fieldName
