It can be combined with all other blocks shown in chapter 4, but it has to be the last block inside a Spock test, as illustrated in figure 5.2. Only an and: block might follow a where: block (and that would be rare).

Figure 5.2. A where: clause must be the last block in a Spock test. It contains the differing values for parameterized tests.

The simpler given-expect-when structure was shown in listing 5.2. This works for trivial and relatively simple tests. The more usual way (and the recommended ...
