Hightail — automatic tester for programming contests
By dj3500, 10 years ago, In English

Hi! In this post I would like to introduce you to an application called Hightail.

Hightail is an automatic tester for programming contests such as CodeForces rounds. It will parse the problem statement, extract sample test cases (inputs and outputs) from it, and verify the correctness of your program against them. It is built to provide maximum automation and to relieve the contestant as much as possible.

A list of Hightail's features:

  • parsing problem statements
  • parsing entire contests (autoloading all problems)
  • scheduling contest parsing ahead of time
  • ability to comfortably view, edit and add test cases
  • handling of all verdicts: WA, TLE, RE, even AC
  • customizable time limits
  • ability to create in/out files in your working directory
  • detection of floating point values (comparing 0.1 vs. 0.10 does not give WA)
  • easy-to-use UI, keyboard shortcuts
  • resilient: it is multi-threaded so it will not let your program hang it; it will withstand large amounts of output from your program
  • support for all contest languages (C++, Java, Python, ...)
  • written in Java and should run on any OS

Some screenshots to give you an idea:

Screenshot 1 Screenshot 2

You will find more information on its homepage (scroll down to see the readme). And here's a direct link to downloads.

Hightail started out as a simple program that I wrote for myself quite some time ago, then it became a small open source project when some other people contributed code to it. I think that it is now sufficiently developed that it can be released to the public, i.e. announced publicly here, rather than being hidden somewhere on the net, possible to find only if you already know the name. (It's probably long overdue, actually.)

If you see bugs, have feature suggestions etc., please use GitHub to its fullest extent :) And look at the readme — it has a tutorial on how to contribute to Hightail.

I hope it will be useful to you :)

I've tried testing my last contest's problem and it works nicely. I've been hoping a long time for a tool like this! I really look forward to using it on my next contest :)

Congratulations for the great work!

First,thank you for the awesome tool. Second, one small advise, you may add this feature in the future version. Some problems just allow multiple correct answers, with some words like "if multiple answer exists, print any of them". If this tool can sense this and remind me "Though your answer differs with the standard answer, but it might be correct.",this tool will be more lovely. Thanks again.

    Maybe you specify the wrong executable file? Because, I thought that there must be cpp file and "Hightail" was waiting on running, too. After I fixed this, everything worked properly.

      Oh, I have some problems with the scheduled contest.

      Ten minutes before a CF contest, I was unable to parse a contest. (Is that OK?)

      So I set up a scheduled contest, but when the contest starts, it just come up with some words like "Scheduled failed". I have to parse the contest manually. Though it only takes several seconds.

      Any help? Thanks.

    To quote from the readme:

    To get a fairly up-to-date version — in the form of a .jar file which is ready to run if you have Java (JRE) installed — visit Downloads. Just save it somewhere on your computer and run it from there. It will create a config file in its directory.

        Did you install Hightail using snap? I think that is currently not working, so try instead to just download the .jar file from the Releases page and run it by double-clicking.

    Well, I think it's right — the executable does not exist (unless you like to name your executables like A.exe even under Linux :) ). Point it to the compiled executable file (if you compile it with g++ with no options, it is usually called a.out).

        This is more of a philosophical question :) I think that testing on the samples is a nuisance and a distraction which is better eliminated so that you can focus on the problems. It can actually save a lot of time sometimes when you don't get the program right from the start, but every time you correct it, there is one testcase (not always the same one) which doesn't pass... and so on. The time you gain will not only give you slightly more points, but sometimes you might be able to solve one more whole problem in the last minute ;)

        Of course it's just that. It won't actually make you a better coder in any way.

First of all i'm sorry for my bad English .

My question is that why this application use executable file to test our code ? Why not main source code ? Coz ,when we debug our code, we need to update our executable file by compilation . But if this app uses our source file directly, we just need to save our new code only.

Btw, Thanx for this awesome application :)

    It's a design decision which might change in later versions (but probably not anytime soon). The downside is that the configuration (and the entire application) would be made more complicated. And when there are compilation errors, we would have to display them somewhere, and we couldn't do it as nicely as an IDE would (pointing the user to the line with the error etc.). Also, should we display warnings or not? The assumption is now just that the user will compile the source code themselves.

As you are developing this in Java it would probably be good idea to have common API for parsers for Hightail and CHelper so that if someone write parser it could be used by both

    Sorry for not replying for so long, but I didn't get a notification email from CodeForces...

    I agree this would be a good thing. Are you suggesting to unify the interfaces of the parsers, or also the libraries that they use (Hightail parsers now use a HTML parser library that I don't enjoy too much, but it gets the job done)? Do you have a more concrete proposal of what this should look like?

    My thoughts exactly :) https://github.com/dj3500/hightail/issues/29

    I'm afraid it would be hard to display both in the same textarea (at least it would be hard to maintain the relative order in which lines are output by the program). But something might be possible.

        print functions usually flush on newline if they detect that program is run from tty, you could try to make it think that it's run from terminal when it's run by you.

      Though the idea of converting lines that start with "DBG:" to green doesn't entirely solve the problem, it would be very useful; adding "DBG:" to my template before each round is a very low price for the great benefits of being able to use Hightail both debugging and testing.

      Thanks for the quick answer :)

It seems that hightail leaves the tests hanging on round #288 B with the code I submitted on contest. It tests the first case and sometimes returns the result but the rest seems to be untested. It shows as I could abort the testing but nothing happens. It works fine on the other problems from that round though.

First of all thanks for making this software, it seems very good. However I do have an issue right now. I would like to use Hightail to run python codes. This is all well and good, and when I put python in the "Command to prepend executable with" the hightail software successfully runs the Python 2.7 I have installed on my computer. However I would like to use Python 3 that I have. Now in the terminal I can run a python file as python 3 by just typing python3 and the name of the python file. However when I put python3 rather than python in the dialog box for hightail it does not work, as when I run the tests it simply says running... for infinite time. Do you have any advice for how I can get hightail to run my Python codes as Python 3? Many thanks in advance. Also, I am on mac if this makes a difference.

    Hmm. If you can run python3 from the console, then it should be on the system PATH, but maybe it's somewhat different under Mac... Maybe you can put the full path to the python3 script in Hightail?

Hi...
What's wrong with hightail?! It fails repeatedly on parsing contests!!!
I couldn't use it for recently contests at all because of "Parsing Failed"!

    Do you mean the Rockethon? It didn't work because one of the tasks (D1) was unparseable (for some reason it displayed nothing, and the problem statement was only shown on the D2 tab).

    In general, if it can't load all problems (because of CodeForces load or unavailability), it won't parse a contest. The only solution now is to retry until it does.

      No, it was recent codeforces round #291. I tried other contests, but it failed too!
      I can open codeforces on contests time, but can't parse problems by hightails.

Hi. Apparently, my program is getting TLE for large test cases when using hightail (using a time limit of 1.0s) but when I manually input the test case file in terminal, my code runs in 0.09s.

Also, is it possible to request to add "load test cases" feature so that we don't have to manually re-enter all our test cases every time we load hightail?

    Could you raise this issue on GitHub? Try to give an example of an input and a program for which this behaviour appears.

    For the second one, please also open an issue. Although the chances that someone will implement this are not so high :) I always envisioned Hightail rather as a tool for situations where you solve a problem in one shot (without restarting your computer etc.).

I think there is an issue with Hightail on Mac OS. Hightail keeps showing 'Running' for files which are located in folders whose names contain spaces.

Take a look at this screenshot. In this picture there are no spaces in any of the folders.

Now take a look at this picture. In this screenshot the directory "ds" has been changed to "d s" and Hightail shows 'Running'.

Is there any fix for this problem?

      Well, I'm only thinking about it yet. Basically, I'd like to use most of the interface. What I want to change:

      1. Use CHelper parsers, because they support more platforms, GCJ and FHC being the most important for me.

      2. Generate a project using CMake and launch tests from IDE instead of the app. This way I don't need to switch between windows at all and debugging will be much more natural.

      3. Use Testlib checkers instead of internal one to be consistent with online judge environment and enable custom checker support.

      4. Integrate library code inlining somewhere in the pipe.

Is there any way to show error stream (cerr in C++ instead of cout) in Hightail?
Thanks for this awesome program btw!

EDIT: Say a problem has x time limit, when a user creates a new test, (imho) it's better to set default time limit of the new test to x instead of default 3 seconds. So we don't need to manually set the time limit for each new test. Thanks for hearing my opinion :)

Hi,

I recently started using it and I love it. I use Sublime to code in C++ on my Mac, and I was trying to use the prepend command feature to compile the file. Eg. I have in the path A.cpp, and a command "g14 name" that compiles name.cpp into name.exe I tried prepend command = g14 %P; But this doesn't work because %P does not evaluate to "A" in the prepend command. Is there any way to do this?

    You would need to make a script that both compiles and runs your file (like make a && ./a on unix). Then have the prepend command be g14 (with a space after) and the path from ... be %P. That should work...

        Note that it runs like: r14 /Users/.../a rather than /Users/.../r14 a. So you should make sure that r14 is in your PATH, for example. Try running r14 /Users/.../a from the console and see if that works.

Many people use file input-output for debugging and testing during the contest using freopen(c++). So the executable file expects the input from the input file and writes to the output file. Can you add functionality that makes hightail work from the specified input method for the executable? Basically, before running the executable, write the input to the file and read the output from the file as well.

    Do This —

    1- Go to the location of file and select it.

    2- click ctrl + I and go to Permissions tab.

    3- there's a row named execute, tick the "Allow executing file as program" option.

    And you're probably done, now double clicking would work, if still there's an error, do this and you're done.
