Configuration

simplecov-console is configurable through environment variables and/or via Ruby code, generally in your test helper or setup file.

Options

SimpleCov::Formatter::Console.sort = 'path' # sort by file path
SimpleCov::Formatter::Console.show_covered = true # show all files in coverage report
SimpleCov::Formatter::Console.max_rows = 15 # integer
SimpleCov::Formatter::Console.max_lines = 5 # integer
SimpleCov::Formatter::Console.missing_len = 20 # integer
SimpleCov::Formatter::Console.output_style = 'block' # 'table' (default) or 'block'
SimpleCov::Formatter::Console.table_options = {:style => {:width => 200}}

Note that all options except table_options can also be set via env var using the uppercase name, e.g., MAX_ROWS.

Disabling colorized output

Color support is active by default. To disable, export NO_COLOR=1:

NO_COLOR=1 rake test

Sorting the output

By default the coverage report sorts by coverage % in descending order. To sort alphabetically by path:

SimpleCov::Formatter::Console.sort = 'path' # sort by file path

Showing covered files

By default, fully covered files are excluded from the report. To include them:

SimpleCov::Formatter::Console.show_covered = true # show all files in coverage report

Maximum rows displayed

By default, a maximum of 15 files with the worst coverage are displayed in the report. To override this limit:

SimpleCov::Formatter::Console.max_rows = 20 # integer

Setting a value of -1 or nil (in Ruby) will show all files.

Maximum lines displayed

By default, all missing lines will be included for each displayed file. For large source files with poor coverage, this may become unwieldy. To show fewer groups of lines:

SimpleCov::Formatter::Console.max_lines = 5 # integer

Maximum length of missing lines

As an alternative to the above max_lines option, you may limit the missing lines output by number of characters:

SimpleCov::Formatter::Console.missing_len = 20 # integer

Table options

In some cases, you may need to pass some options to TerminalTable.new. For example, if the filenames truncate so much that you can't read them, try increasing the table width:

SimpleCov::Formatter::Console.table_options = {:style => {:width => 200}}

Block output style

As an alternative to the default table output format, a simpler block format is also available:

SimpleCov::Formatter::Console.output_style = 'block'

Example output:

COVERAGE:  82.34% -- 2345/2848 lines in 111 files

showing bottom (worst) 5 of 69 files

    file: lib/bixby/api/websocket_server.rb

Branch Coverage Support

When branch coverage is enabled in simplecov, branch info will automatically be displayed in the output:

COVERAGE:  78.26% -- 18/23 lines in 2 files
BRANCH COVERAGE:  83.33% -- 5/6 branches in 2 branches

Contributing

Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet.
Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it.
Fork the project.
Start a feature/bugfix branch.
Commit and push until you are happy with your contribution.
Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
