# Starts an expectation on a block of code.
|

# This should be followed up with `to` or `to_not`.

# The block passed in, or its return value, will be checked
|

# to see if it satisfies the conditions specified.

|

# This method is identical to `#expect`,
|
||||
# but is grammatically correct for the one-liner syntax.
|
||||
# It can be used like so:
|
||||
# ```
|
||||
# it expects { 5 / 0 }.to raise_error
|
||||
# ```
|
||||
# The block of code is passed along for validation to the matchers.
|
||||
#
|
||||
# The short, one argument syntax used for passing methods to blocks can be used.
|
||||
# So instead of doing this:
|
||||
# ```
|
||||
# it expects(subject.size).to eq(5)
|
||||
# ```
|
||||
# The following syntax can be used instead:
|
||||
# ```
|
||||
# it expects(&.size).to eq(5)
|
||||
# ```
|
||||
# The method passed will always be evaluated on `#subject`.
|
||||
macro expects(&block)
|
||||
expect {{block}}

# Short-hand for expecting something of the subject.
