Struct subplotlib::scenario::Scenario

pub struct Scenario { /* fields omitted */ }

The embodiment of a subplot scenario

Scenario objects are built up by the generated test functions and then run to completion. In rare cases they may be built up and cached for reuse for example if a scenario is a subroutine.

Implementations

impl Scenario

pub fn new(title: &str) -> Self

Create a new scenario with the given title

pub fn title(&self) -> &str

Retrieve the scenario title

pub fn add_step(&mut self, step: ScenarioStep, cleanup: Option<ScenarioStep>)

Add a scenario step, with optional cleanup step function.

pub fn register_context_type<C>(&self) where
    C: ContextElement, 

Register a type with the scenario contexts

pub fn run(self) -> Result<(), StepError>

Run the scenario to completion.

Running the scenario to completion requires running each step in turn. This will return the first encountered error, or unit if the scenario runs cleanly.

Panics

If any of the cleanup functions error, this will immediately panic.
