The "testing" section of the rust book needs a small correction

[lucatrv]

The code example at https://doc.rust-lang.org/book/testing.html#documentation-tests should be corrected changing mod tests { into mod test {.

[steveklabnik]

nice catch!

[callahad]

Should this instance be mod test, or should everything else be mod tests instead?

Judging from crates.io, it looks like mod tests is more common. Granted, half of it is alexcrichton, but still ;-)

Incoming PR to that effect.

$ grep -r 'mod tests {' src/lib* | wc -l
      63
$ grep -r 'mod test {'  src/lib* | wc -l
      58

Oh, really now?

[lucatrv]

I actually vote for everything else to be mod tests.

[callahad]

Aw, shoot. From some more grepping, the style guide and the language reference both refer to mod test. Going with that.

[lucatrv]

Ok but... to me it doesn't make sense that we use mod test and then we name the folder tests, as they both can contain multiple tests...
