A reminder why a test should fail first. The following test is green:
def "test absolutely nothing"() {
when:
def list = [1, 2, 3]
then:
list.each {
it > 0
}
}
The following test is also green:
def "test absolutely nothing"() {
when:
def list = [-1, -2, -3]
then:
list.each {
it > 0
}
}
The Spock framework documentation states for then and expect blocks:
Except for calls to void methods and expressions classified as interactions, all top-level expressions in these blocks are implicitly treated as conditions.
To repair the test we have to assert ourselves:
assert it > 0
