Example 6 with Constraints

use of org.evosuite.runtime.annotation.Constraints in project evosuite by EvoSuite.

Example 7 with Constraints

            }
        // it might be a bean with its own dependency injections.
        // but those should be handled in its instantiation
        } catch (IllegalAccessException e) {
            // shouldn't really happen
            logger.warn(e.toString());
