Defined in:
lib/spec/rake/spectask.rb

Overview

A Rake task that runs a set of RSpec contexts.

Example:

Spec::Rake::SpecTask.new do |t|
  t.warning = true
  t.rcov = true
end

This will create a task that can be run with:

rake spec

If rake is invoked with a “SPEC=filename” command line option, then the list of spec files will be overridden to include only the filename specified on the command line. This provides an easy way to run just one spec.

If rake is invoked with a “SPEC_OPTS=options” command line option, then the given options will override the value of the spec_opts attribute.

If rake is invoked with a “RCOV_OPTS=options” command line option, then the given options will override the value of the rcov_opts attribute.

Examples:

rake spec                                      # run specs normally
rake spec SPEC=just_one_file.rb                # run just one spec file.
rake spec SPEC_OPTS="--diff"                   # enable diffing
rake spec RCOV_OPTS="--aggregate myfile.txt"   # see rcov --help for details

Each attribute of this task may be a proc. This allows for lazy evaluation, which is sometimes handy if you want to defer the evaluation of an attribute value until the task is run (as opposed to when it is defined).

Instance Attribute Details

#fail_on_error ⇒ Object

Whether or not to fail Rake when an error occurs (typically when specs fail). Defaults to true.

# File 'lib/spec/rake/spectask.rb', line 94

def fail_on_error
  @fail_on_error
end

#failure_message ⇒ Object

A message to print to stderr when there are failures.

# File 'lib/spec/rake/spectask.rb', line 97

def failure_message
  @failure_message
end

#libs ⇒ Object

Array of directories to be added to $LOAD_PATH before running the specs. Defaults to [‘<the absolute path to RSpec’s lib directory>‘]

# File 'lib/spec/rake/spectask.rb', line 62

def libs
  @libs
end

#name ⇒ Object

Name of spec task. (default is :spec)

60
 
# File 'lib/spec/rake/spectask.rb', line 58

def name
  @name
end

#out ⇒ Object

Where RSpec’s output is written. Defaults to STDOUT. DEPRECATED. Use –format FORMAT:WHERE in spec_opts.



101

103
 
# File 'lib/spec/rake/spectask.rb', line 101

def out
  @out
end

#pattern ⇒ Object

Glob pattern to match spec files. (default is ‘spec/*/_spec.rb’) Setting the SPEC environment variable overrides this.

72
 
# File 'lib/spec/rake/spectask.rb', line 70

def pattern
  @pattern
end

#rcov ⇒ Object

Whether or not to use RCov (default is false) See eigenclass.org/hiki.rb?rcov



78

80
 
# File 'lib/spec/rake/spectask.rb', line 78

def rcov
  @rcov
end

#rcov_dir ⇒ Object

Directory where the RCov report is written. Defaults to “coverage” Ignored if rcov=false



87
88
89
 
# File 'lib/spec/rake/spectask.rb', line 87

def rcov_dir
  @rcov_dir
end

#rcov_opts ⇒ Object

Array of commandline options to pass to RCov. Defaults to [‘–exclude’, ‘lib/spec,bin/spec’]. Ignored if rcov=false Setting the RCOV_OPTS environment variable overrides this.



83
84
85
 
# File 'lib/spec/rake/spectask.rb', line 83

def rcov_opts
  @rcov_opts
end

#ruby_opts ⇒ Object

Array of commandline options to pass to ruby. Defaults to [].



90
91

# File 'lib/spec/rake/spectask.rb', line 90

def ruby_opts
  @ruby_opts
end

#spec_files ⇒ Object

Explicitly define the list of spec files to be included in a spec. spec_files is expected to be an array of file names (a FileList is acceptable). If both pattern and spec_files are used, then the list of spec files is the union of the two. Setting the SPEC environment variable overrides this.



108
109
110
 
# File 'lib/spec/rake/spectask.rb', line 108

def spec_files
  @spec_files
end

#spec_opts ⇒ Object

# File 'lib/spec/rake/spectask.rb', line 74

def spec_opts
  @spec_opts
end

#warning ⇒ Object

If true, requests that the specs be run with the warning flag set. E.g. warning=true implies “ruby -w” used to run the specs. Defaults to false.
