Empty region names and missing javadoc for `Sort.arrayCopy`

[tyuldashev]

Description

To Reproduce

    public int[] arrayCopy() {
        int[] fst = {1, 2, 3};
        int[] snd = {4, 5, 6};

        System.arraycopy(fst, 0, snd, 0, 3);
        return snd;
    }

Steps to reproduce the behavior:

1. Open algorithms/Sort.java sample from UTBot project
2. Or use code sample from above.
3. In plugin settings set generation method to 95% Symbolic
4. Use plugin to generate tests
5. Open the generated test

Expected behavior

Every test is placed in region with name and has proper java doc description

Actual behavior

Quite many regions have no names and some tests have no javadocs

Visual proofs (screenshots, logs, images)

Here is one of generated test:

public class SortTest {
    ///region Test suites for executable org.example.Sort.arrayCopy

    ///region

    @Test
    public void testArrayCopy1() {
        Sort sort = new Sort();

        int[] actual = sort.arrayCopy();

        int[] expected = {1, 2, 3};
        assertArrayEquals(expected, actual);
    }

...

@tyuldashev the default behaviour - do not generate summaries/regions if something goes wrong (it should be logged by logger.error to the log). We are not guarantee at this moment that all tests will have regions and other summaries.

Sometimes it's a developer bug in summaries, sometimes it's the limitation of summaries functionality.

I suggest or copy the reason of crash from logs (if it's the same it's one bug if is different—there are a few bugs) or copy generated results (with missed summaries)

@alisevych for copy

On my laptop looks like it's reproduced and related to the problem #1227

[alisevych]

It is reproducing for a certain number of tests.
Now - for Sort.partition and Sort.quickSort - on the latest main

idea.log doesn't contain the information about missing data, neither do concrete executor log.

@amandelpie It would be great if you investigate (debug) what exact data is missing for these executions.
Then this bug could be handled to the correct developer.

@tyuldashev @alisevych Looks like it was fixed by #1227 closed earlier, it's not reproduced on my side

[amandelpie]

@tyuldashev @alisevych please reproduce and close, the bug is not reproduced on the master and closed earlier

For example, the following test is generated

public final class SortTest {
    ///region Test suites for executable custom.Sort.arrayCopy

    ///region FUZZER: SUCCESSFUL EXECUTIONS for method arrayCopy()

    /**
     * @utbot.classUnderTest {@link Sort}
     * @utbot.methodUnderTest {@link Sort#arrayCopy()}
     */
    @Test
    @DisplayName("arrayCopy: arg_0 = Sort()")
    public void testArrayCopy() {
        Sort sort = new Sort();

        int[] actual = sort.arrayCopy();

        int[] expected = {1, 2, 3};
        assertArrayEquals(expected, actual);
    }
    ///endregion

    ///endregion
}
