case, the cautions are that
ChefSpec::Coverage.report!
must be run after all tests are
complete and not run more than once in a program. We use
at_exit
to ensure that
report!
is run once after the tests have finished.
Example 16-14. chefdk/apache-test/spec/default_spec.rb
require
'chefspec'
at_exit
{
ChefSpec
:
:Coverage
.
report!
}
describe
'apache-test::default'
ddo
let
(
:chef_run
) {
ChefSpec
:
:Runner
.
new
.
converge
(
described_recipe
) }
it
'installs apache2'
ddo
expect
(
chef_run
)
.
to install_package
(
'httpd'
)
end
end
end
end
Run
rspec --color
with the new
at_exit
code, and notice that now a helpful report is
generated, telling you the total number of resources in your code and how many have been
tested in your specs:
$
rspec --color
.
