Trait cucumber::writer::Summarizable
source · pub trait Summarizable { }Expand description
Marker indicating that a Writer can be wrapped into a Summarize.
Not any Writer can be wrapped into a Summarize, as it may transform
events inside and the summary won’t reflect outputted events correctly.
So, this trait ensures that a wrong Writers pipeline cannot be build.
§Example
ⓘ
MyWorld::cucumber()
.with_writer(
// `Writer`s pipeline is constructed in a reversed order.
writer::Basic::stdout()
.fail_on_skipped() // Fails as `Summarize` will count skipped
.summarized() // steps instead of failed.
)
.run_and_exit("tests/features/readme")
.await;MyWorld::cucumber()
.with_writer(
// `Writer`s pipeline is constructed in a reversed order.
writer::Basic::stdout() // And, finally, print them.
.summarized() // Only then, count summary for them.
.fail_on_skipped(), // First, transform skipped steps to failed.
)
.run_and_exit("tests/features/readme")
.await;
