I have fixed both sample tests and test cases file. As you have already attempted it, your sample test section will keep showing old code. In that case you can copy paste this new code in sample tests section.

import org.junit.jupiter.api.Test;
import static org.junit.jupiter.api.Assertions.assertEquals;

class SampleTests {
    private static void doTest(boolean actual, boolean expected) {
        assertEquals(expected, actual);
    }
  
    @Test
    void FixedTests() {
        doTest(Kata.willRobotsCollide(0, 0, 1, 0, "UL"), true);
        doTest(Kata.willRobotsCollide(0, 0, 0, 1, "LRLR"), false);
        doTest(Kata.willRobotsCollide(5, 1, 1, 5, "LRUURLDDLR"), true);
        doTest(Kata.willRobotsCollide(5, 0, 1, 5, "LRUURLDDLR"), false);
        doTest(Kata.willRobotsCollide(4, 2, 3, 2, "R"), true);
        doTest(Kata.willRobotsCollide(4, 2, 3, 2, "D"), false);
        doTest(Kata.willRobotsCollide(8, 6, 8, 6, ""), true);
        doTest(Kata.willRobotsCollide(8, 6, 8, 7, ""), false);
    }
}

Please Copy-paste eight sample test cases as fixed test cases in Test Cases file.

Random test cases should test for generate-random-case 500 too (100 test cases of parameter 500). Because we don't want brute force solution to pass the tests. We want only most optimized solution to pass the random test cases.

Done.

Should I mark this issue as resolved?

How do I include it? Commented solution at the bottom of test cases file?

I DMed the solutions on Discord. My username is pythonist1159 there.

Please add four new test cases in Sample tests and Fixed/Basic tests of OCaml translation.

let trueCount = 0;
for (let i = 0; i < 100; i++) {
    const [x1, y1, x2, y2, cmds, expected] = generateTestCase(randInt(1000));
    if (expected === true) trueCount += 1;
}

console.log("JS true count", trueCount);

Output:

JS true count 58
JS true count 49
JS true count 54
JS true count 58

true_count = 0
for _ in range(100):
    x1, y1, x2, y2, cmds, expected = generate_testcase(random.randint(0, 1000))
    true_count += int(expected)

print("Expected True Count:", true_count)

Output:

Expected True Count: 53
Expected True Count: 58
Expected True Count: 55
Expected True Count: 62

To be more precise, It is around 55/45 for JS and Python.

If you want me to set specs back to 500, I will do it.

Coming to random spray, it is generating around 50/50 true/false, at least for Python and JS.

The system is not letting me approve your translation due to merge conflict in Problem statement. BTW I have made some changes in test cases and problem statement, I encourage you to update Scala and OCaml translations accordingly.

1. Change in Constraints

0 <= x1, y1, x2, y2 <= 1000
0 <= len(commands) <= 1000

2. Four new test cases added in Sample Tests and Fixed Tests.
3. Random test cases are now of random lengths. The len(commands) for each test case is calculated randomly.

I updated the test cases according to your suggestios. I encourage you to update Haskell translation accordingly.

1. Change in Constraints Constraints set back to 500 but includes 0.

0 <= x1, y1, x2, y2 <= 500
0 <= len(commands) <= 500

2. Four new test cases added in Sample Tests and Fixed Tests.
3. Random test cases are now of random lengths. The len(commands) for each test case is calculated randomly.
