Indicates that iterations of a data-driven feature should be made visible
as separate features to the outside world (IDEs, reports, etc.). By default,
the name of an iteration is the feature's name followed by a consecutive number.
This can be changed by providing a naming pattern after @Unroll. A naming pattern
may refer to data variables by prepending their names with #. Example:
@Unroll("#name should have length #length")
def "name length"() {
expect:
name.size() == length
where:
name << ["Kirk", "Spock", "Scotty"]
length << [4, 5, 6]
}
Alternatively, the naming pattern can also be embedded in the method name:
@Unroll
def "#name should have length #length"() {
...
}
The
Unroll annotation can also be put on a spec class. This has the same
effect as putting it on every data-driven feature method that is not already
annotated with
Unroll. By embedding the naming pattern in the method
names, each method can still have its own pattern.
