Tests for the tokenize module.
|

|

The tests were originally written in the old Python style, where the
|
||||
test output was compared to a golden file. This docstring represents
|
||||
the first steps towards rewriting the entire test as a doctest.

A comment generates a token here, unlike in the parser module. The

comment token is followed by an NL or a NEWLINE token, depending on

whether the line contains the completion of a statement.

There will be a bunch more tests of specific source patterns.
|
||||
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.
|
||||
|
||||
The tokenize module also defines an untokenize function that should
|
||||
regenerate the original program text from the tokens.

|

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 apparent in the expected output.
