Method: ShellTest::ShellMethods::Session#parse

Defined in:
lib/shell_test/shell_methods/session.rb

#parse(script, options = {}, &block) ⇒ Object

Parses a terminal snippet into steps that a Session can run, and adds those steps to self. The snippet should utilize ps1 and ps2 as set on self. An exit command is added unless the :noexit option is set to true.

session = Session.new
session.parse %{
$ echo abc
abc
}
session.run.result   # => "$ echo abc\nabc\n$ exit\nexit\n"

Steps are registered with a callback block, if given, to recieve the expected and actual outputs during run. Normally the callback is used to validate that the run is going as planned.
