In-Depth Information
The idea is that even if the mock is configured to throw an exception, the tribble test still
passes. The test verifies that the exception is thrown without making the test itself fail.
6.4.5. Other Spock capabilities
The capabilities shown so far hopefully provide a teaser for Spock. There are more features
in Spock that go beyond the scope of this chapter. For example, the
@Ignore
annotation
on a test skips that test, but there's also an
@IgnoreRest
annotation that skips all the
other tests instead. The
@IgnoreIf
annotation checks a Boolean condition and skips the
test if the condition evaluates to true. There's also a
@Stepwise
annotation for tests that
have to be executed in a particular order, and a
@Timeout
annotation for tests that are
taking too long to execute.
Lessons learned (Spock)
1
. Spock tests extend
spock.lang.Specification
2
. The
Specification
class has a JUnit runner, so Spock tests run in your exist-
ing JUnit infrastructure.
3
. Spock test names are descriptive sentences. The framework uses AST transforma-
tions to convert them to legal Groovy.
4
. The tests are composed of blocks, like
expect
or
when/then
. Expressions in
an
expect
or
then
block are evaluated for the Groovy Truth automatically.
5
. The
old
method from
spock.lang.Specification
evaluates its argument
before the
when
block is executed.
6
. The
where
block is used to iterate over test data, either from a table, a database
result, or any data structure over which Groovy can iterate.
7
. Spock has its own built-in mocking capabilities.
