Class | RCov::VerifyTask |
In: |
lib/spec/rake/verify_rcov.rb
|
Parent: | Rake::TaskLib |
A task that can verify that the RCov coverage doesn‘t drop below a certain threshold. It should be run after running Spec::Rake::SpecTask.
index_html | [RW] | Path to the index.html file generated by RCov, which is the file containing the total coverage. Defaults to ‘coverage/index.html‘ |
name | [RW] | Name of the task. Defaults to :verify_rcov |
require_exact_threshold | [RW] | Require the threshold value be met exactly. This is the default. |
threshold | [RW] | The threshold value (in percent) for coverage. If the actual coverage is not equal to this value, the task will raise an exception. |
verbose | [RW] | Whether or not to output details. Defaults to true. |
