Tests for the tokenize module.

    >>> import glob, random, sys

The tests can be really simple. Given a small fragment of source
code, print out a table with tokens. The ENDMARK is omitted for
brevity.

    IndentationError: unindent does not match any outer indentation level

Test roundtrip for `untokenize`. `f` is an open file or a string. The source
code in f is tokenized, converted back to source code via tokenize.untokenize(),
and tokenized again from the latter. The test fails if the second tokenization
doesn't match the first.

    >>> def roundtrip(f):
    ...     if isinstance(f, str): f = StringIO(f)
    ...     token_list = list(generate_tokens(f.readline))
    ...     f.close()
    ...     tokens1 = [tok[:2] for tok in token_list]
    ...     new_text = untokenize(tokens1)
    ...     readline = iter(new_text.splitlines(1)).__next__
    ...     tokens2 = [tok[:2] for tok in generate_tokens(readline)]
    ...     return tokens1 == tokens2
    ...

There are some standard formattig practises that are easy to get right.

    >>> roundtrip("if x == 1:\\n"
    ...           "    print(x)\\n")
    True

    >>> roundtrip("# This is a comment\\n# This also")
    True

Some people use different formatting conventions, which makes
untokenize a little trickier. Note that this test involves trailing
whitespace after the colon. Note that we use hex escapes to make the
two trailing blanks apperant in the expected output.

    >>> roundtrip("if x == 1 : \\n"
    ...           "  print(x)\\n")
    True

    >>> f = test_support.findfile("tokenize_tests.txt")
    >>> roundtrip(open(f))
    True

    >>> roundtrip("if x == 1:\\n"
    ...           "    # A comment by itself.\\n"
    ...           "    print(x) # Comment here, too.\\n"
    ...           "    # Another comment.\\n"
    ...           "after_if = True\\n")
    True

    >>> roundtrip("if (x # The comments need to go in the right place\\n"
    ...           "    == 1):\\n"
    ...           "    print('x==1')\\n")
    True

    >>> roundtrip("class Test: # A comment here\\n"
    ...           "  # A comment with weird indent\\n"
    ...           "  after_com = 5\\n"
    ...           "  def x(m): return m*5 # a one liner\\n"
    ...           "  def y(m): # A whitespace after the colon\\n"
    ...           "     return y*4 # 3-space indent\\n")
    True

Some error-handling code

    >>> roundtrip("try: import somemodule\\n"
    ...           "except ImportError: # comment\\n"
    ...           "    print 'Can not import' # comment2\\n"
    ...           "else:   print 'Loaded'\\n")
    True

Balancing continuation

    >>> roundtrip("a = (3,4, \\n"
    ...           "5,6)\\n"
    ...           "y = [3, 4,\\n"
    ...           "5]\\n"
    ...           "z = {'a': 5,\\n"
    ...           "'b':15, 'c':True}\\n"
    ...           "x = len(y) + 5 - a[\\n"
    ...           "3] - a[2]\\n"
