| TESTLIB | ||
|
|
||
| == What is it? == | ||
| Testlib is simple library which helps you to write | ||
| * checkers | ||
| * validators | ||
| * generators | ||
| * interactors | ||
| for programming competitions problems. | ||
| You can find latest release of the library on https://github.com/MikeMirzayanov/testlib/ | ||
| Problem development management system Polygon completely supports testlib. | ||
|
|
||
| == How to use? == | ||
| Easest way is to read c++ sources in the checkers/, validators/, generators/ and interactors/ folders. | ||
| Also some classes and methods in testlib have documentation. | ||
|
|
||
| Thanks for using testlib, | ||

| # Testlib | ||
|
|
||
| ## Intro | ||
|
|
||
| This project contains a C++ implementation of testlib. It is already being used in many programming contests in Russia, such as the Russian National Olympiad in Informatics and different stages of ICPC. Join! | ||
|
|
||
| The library's C++ code is tested for compatibility with standard C++11 and higher on different versions of `g++`, `clang++`, and Microsoft Visual C++. | ||
|
|
||
| This code has been used many times in Codeforces contests. | ||
|
|
||
| ## Samples | ||
|
|
||
| ### Checker | ||
|
|
||
| This sample checker expects the same integer in the output and the answer. It ignores all white-spaces. See more examples in the package. | ||
|
|
||
| ```c++ | ||
| #include "testlib.h" | ||
|
|
||
| int main(int argc, char * argv[]) { | ||
| setName("compares two signed integers"); | ||
| registerTestlibCmd(argc, argv); | ||
| int ja = ans.readInt(); | ||
| int pa = ouf.readInt(); | ||
| if (ja != pa) | ||
| quitf(_wa, "expected %d, found %d", ja, pa); | ||
| quitf(_ok, "answer is %d", ja); | ||
| } | ||
| ``` | ||
|
|
||
| ### Interactor | ||
|
|
||
| This sample interactor reads pairs of numbers from the input file, sends them to another program, reads | ||
| the result, and writes it to an output file (to be verified later). Another option could be to terminate | ||
| the interactor with `quitf(_wa, <comment>)`. | ||
|
|
||
| ```c++ | ||
| #include "testlib.h" | ||
| #include <iostream> | ||
|
|
||
| using namespace std; | ||
|
|
||
| int main(int argc, char* argv[]) { | ||
| setName("Interactor A+B"); | ||
| registerInteraction(argc, argv); | ||
|
|
||
| // reads number of queries from test (input) file | ||
| int n = inf.readInt(); | ||
| for (int i = 0; i < n; i++) { | ||
| // reads query from test (input) file | ||
| int a = inf.readInt(); | ||
| int b = inf.readInt(); | ||
|
|
||
| // writes query to the solution, endl makes flush | ||
| cout << a << " " << b << endl; | ||
|
|
||
| // writes output file to be verified by checker later | ||
| tout << ouf.readInt() << endl; | ||
| } | ||
|
|
||
| // just message | ||
| quitf(_ok, "%d queries processed", n); | ||
| } | ||
| ``` | ||
|
|
||
| ### Validator | ||
|
|
||
| This code reads input from the standard input and checks that it contains only one integer between 1 and 100, inclusive. It also validates that the file ends with EOLN and EOF. On Windows, it expects #13#10 as EOLN, and it expects #10 as EOLN on other platforms. It does not ignore white-spaces, so it works very strictly. It will return a non-zero code in the case of illegal input and write a message to the standard output. See more examples in the package. | ||
|
|
||
| ```c++ | ||
| #include "testlib.h" | ||
|
|
||
| int main(int argc, char* argv[]) { | ||
| registerValidation(argc, argv); | ||
| inf.readInt(1, 100, "n"); | ||
| inf.readEoln(); | ||
| inf.readEof(); | ||
| } | ||
| ``` | ||
|
|
||
| ### Generator | ||
|
|
||
| This generator outputs a random token to the standard output, containing Latin letters or digits. The length of the token will be between 1 and 1000, inclusive. It will use a uniformly distributed random generator. To generate different values, call it with different command-line parameters. It is typical behavior for a testlib generator to set up randseed by command line. See more examples in the package. | ||
|
|
||
| ```c++ | ||
| #include "testlib.h" | ||
|
|
||
| int main(int argc, char* argv[]) { | ||
| registerGen(argc, argv, 1); | ||
| println(rnd.next(1, 10)); /* Random number in the range [1,10]. */ | ||
| println(rnd.next("[a-zA-Z0-9]{1,1000}")); /* Random word of length [1,1000]. */ | ||
| } | ||
| ``` | ||
|
|
||
| This generator outputs a random permutation; the size is equal to the first command-line argument. | ||
|
|
||
| ```c++ | ||
| #include "testlib.h" | ||
|
|
||
| int main(int argc, char* argv[]) { | ||
| registerGen(argc, argv, 1); | ||
|
|
||
| int n = opt<int>(1); | ||
| println(n); | ||
| println(rnd.perm(n, 1)); | ||
| } | ||
| ``` |
