Concrete execution exceptions for Collection<Collection<Double>> #1020

Open alisevych opened 1 year ago

alisevych commented 1 year ago

Description

NoSuchElementException and NullPointerException are thrown from concrete executions by symbolic engine of a method with Collection<Collection> as input.

To Reproduce

  1. Install one of the latest plugin build from main on IntelliJ Idea 2022.1.4
  2. Symbolic execution is on
  3. Add the following method to a Java class:
public static boolean isDiagonal(Collection<Collection<Double>> matrix) {
        int cols = matrix.size();
        if (cols <= 1) {
            return false;
        }
        int i = 0;
        for (Collection<Double> col : matrix) {
            if (col.size() != cols) {
                return false;
            }
            int j = 0;
            for (Double value : col) {
                if (i == j && value == 0.0) return false;
                if (i != j && value != 0.0) return false;
                j++;
            }
            i++;
        }
        return true;
    }
  1. Generate tests with UTBot symbolic execution

Expected behavior

Tests are supposed to be generated.

Actual behavior

An error test is generated with information about errors in the concrete executor.

Update @sergeypospelov Please pay your attention that:

Concrete execution logs have different exceptions and stacktrace:
