function out = runtests(varargin)
%runtests Run unit tests
%   runtests runs all the test cases that can be found in the current directory
%   and summarizes the results in the Command Window.
%
%   Test cases can be found in the following places in the current directory:
%
%       * An M-file function whose name starts or ends with "test" or
%         "Test" and that returns no output arguments.
%
%       * An M-file function whose name starts or ends with "test" or
%         "Test" and that contains subfunction tests and uses the
%         initTestSuite script to return a TestSuite object.
%
%       * An M-file defining a subclass of TestCase.
%
%   runtests(dirname) runs all the test cases found in the specified directory.
%
%   runtests(packagename) runs all the test cases found in the specified
%   package. (This option requires R2009a or later).
%
%   runtests(mfilename) runs test cases found in the specified function or class
%   name. The function or class needs to be in the current directory or on the
%   MATLAB path.
%
%   runtests('mfilename:testname') runs the specific test case named 'testname'
%   found in the function or class 'name'.
%
%   Multiple directories or file names can be specified by passing multiple
%   names to runtests, as in runtests(name1, name2, ...) or
%   runtests({name1, name2, ...}, ...)
%
%   runtests(..., '-verbose') displays the name and result, result, and time
%   taken for each test case to the Command Window.
%
%   runtests(..., '-logfile', filename) directs the output of runtests to
%   the specified log file instead of to the Command Window.
%
%   out = runtests(...) returns a logical value that is true if all the
%   tests passed.
%
%   Examples
%   --------
%   Find and run all the test cases in the current directory.
%
%       runtests
%
%   Find and run all the test cases in the current directory. Display more
%   detailed information to the Command Window as the test cases are run.
%
%       runtests -verbose
%
%   Save verbose runtests output to a log file.
%
%       runtests -verbose -logfile my_test_log.txt
%
%   Find and run all the test cases contained in the M-file myfunc.
%
%       runtests myfunc
%
%   Find and run all the test cases contained in the TestCase subclass
%   MyTestCase.
%
%       runtests MyTestCase
%
%   Run the test case named 'testFeature' contained in the M-file myfunc.
%
%       runtests myfunc:testFeature
%
%   Run all the tests in a specific directory.
%
%       runtests c:\Work\MyProject\tests
%
%   Run all the tests in two directories.
%
%       runtests c:\Work\MyProject\tests c:\Work\Book\tests
