  fail 'The MotionSpec gem must be required within a RubyMotion project Rakefile.'
Severity: Minor
Found in lib/motion-spec.rb by rubocop

This cop checks for uses of fail and raise.

Example: EnforcedStyle: only_raise (default)

# The `only_raise` style enforces the sole use of `raise`.
# bad
begin
  fail
rescue Exception
  # handle it
end

def watch_out
  fail
rescue Exception
  # handle it
end

  ErrorLog = ''
Severity: Minor
Found in lib/motion-spec/core.rb by rubocop

This cop checks whether constant names are written using SCREAMINGSNAKECASE.

To avoid false positives, it ignores cases in which we cannot know for certain the type of value that would be assigned to a constant.

Example:

# bad
InchInCm = 2.54
INCHinCM = 2.54
Inch_In_Cm = 2.54

# good
INCH_IN_CM = 2.54

Unnecessary utf-8 encoding comment.

    def observeValueForKeyPath(_key_path, ofObject:object, change:_, context:__)
Severity: Minor
Found in lib/motion-spec/specification.rb by rubocop

Checks for colon (:) not followed by some kind of space. N.B. this cop does not handle spaces after a ternary operator, which are instead handled by Layout/SpaceAroundOperators.

Example:

# bad
def f(a:, b:2); {a:3}; end

# good
def f(a:, b: 2); {a: 3}; end

Add an empty line after magic comments.

module MotionSpec
Severity: Minor
Found in lib/motion-spec/context_helper/memoized_helpers.rb by rubocop

Checks for a newline after the final magic comment.

Example:

# good
# frozen_string_literal: true

# Some documentation for Person
class Person
  # Some code
end

# bad
# frozen_string_literal: true
# Some documentation for Person
class Person
  # Some code
end

class Numeric
Severity: Minor
Found in lib/motion-spec/extensions/numeric.rb by rubocop

This cop checks for missing top-level documentation of classes and modules. Classes with no body are exempt from the check and so are namespace modules - modules that have nothing in their bodies except classes, other modules, or constant definitions.

The documentation requirement is annulled if the class or module has a "#:nodoc:" comment next to it. Likewise, "#:nodoc: all" does the same for all its children.

Example:

# bad
class Person
  # ...
end

# good
# Description/Explanation of Person class
class Person
  # ...
end

require_lib_files(%w(

Severity: Minor
Found in lib/motion-spec.rb by rubocop

This cop enforces the consistent usage of %-literal delimiters.

Specify the 'default' key to set all preferred delimiters at once. You can continue to specify individual preferred delimiters to override the default.

Example:

# Style/PercentLiteralDelimiters:
#   PreferredDelimiters:
#     default: '[]'
#     '%i':    '()'

%w[alpha beta] + %i(gamma delta)
