Keep in mind that the preceding code is just runnable documentation. The
expect
statement
does not
perform an
httpd
package installation during the in-memory Chef run. Instead,
ChefSpec merely performs the in-memory Chef run to verify the cookbook syntax; in this
case, to ensure that your code instructed Chef to install the package. This form of
documentation-based testing is good enough for well-tested Chef primitives, such as the
package
resource.
Commands in ChefSpec are usually the results of an in-memory Chef run. ChefSpec match-
ers are documented[ChefSpec matchers] are documented as shown in
Figure 16-18
