Generating coverage reports during software testing can be quite beneficial. While they don’t ensure comprehensive testing, these reports can reveal areas where test coverage is insufficient. This is particularly relevant for legacy systems or projects that lack adequate testing.
Recently, I encountered a scenario where I needed to create a coverage report, but the project utilized multiple testing frameworks. One framework was designated for unit testing, while another was used for integration testing. Thankfully, SimpleCov simplifies the process of merging coverage reports.
Basic SimpleCov Usage
To implement SimpleCov, you typically require the simplecov gem and then invoke SimpleCov.start with various configuration options. Here’s an example configuration from an RSpec test helper:
require 'simplecov'
SimpleCov.start do
# configure SimpleCov
end
require 'rspec'
require 'my-library'
When working with multiple testing frameworks, you might find it necessary to replicate this configuration code. Instead, consider relocating the shared SimpleCov setup to a .simplecov file, which Ruby can parse. I prefer to conditionally execute SimpleCov based on an environment variable. Here’s how it looks:
# in .simplecov
if ENV['COVERAGE']
SimpleCov.start do
# configure SimpleCov
end
end
With this setup, my test helpers can be streamlined to:
require 'simplecov'
require 'rspec'
require 'my-library'
Finally, when using Rake, I like to enable the generation of coverage reports for unit tests, integration tests, or both. This is achieved by organizing my test tasks as follows:
task 'test:unit' do
# ...
end
desc 'Runs integration tests'
task 'test:integration' do
# ...
end
desc 'Runs unit and integration tests'
task 'test' => ['test:unit', 'test:integration']
desc 'Generate coverage report'
task 'coverage' do
ENV['COVERAGE'] = true
rm_rf "coverage/"
task = Rake::Task['test']
task.reenable
task.invoke
end
