The

@Unroll

annotation causes that a test name will be unrolled for every combination of test data. It means that we can have multiple tests having different name, which in fact are related with exactly the same test method, but ran with different input arguments.

Examples (from http://docs.spockframework.org/en/latest/data_driven_testing.html):

// sequence index at the end
@Unroll
def "maximum of two numbers"() { ... }
maximum of two numbers[0]   PASSED
maximum of two numbers[1]   FAILED

// variable substitution 
@Unroll
def "maximum of #a and #b is #c"() { ... }
maximum of 3 and 5 is 5   PASSED
maximum of 7 and 0 is 7   FAILED

Problem for Clover: we don't know neither a number of tests nor their names during compilation. it would have to be deferred to runtime.

=> add some inner class for a test class which would monitoring the test name and somehow pass to the per-test coverage recorder?
