Listing 10.7. Using GroovyShellTestCase to simplify unit-testing groovlets

The GroovyShellTestCase class instantiates a GroovyShell internally and allows
you to pass a map of binding parameters through the withBinding method.

10.2.2. Implicit variables in groovlets

The previous example shows that groovlets expect that all the request parameters are
bundled into a map called params . Groovlets operate in an environment containing many
implicit variables. Table 10.2 shows the complete list.
