Class TestSuiteLocalSearch

java.lang.Object

org.evosuite.testsuite.localsearch.TestSuiteLocalSearch

All Implemented Interfaces:

LocalSearch<TestSuiteChromosome>

public class TestSuiteLocalSearch
extends Object
implements LocalSearch<TestSuiteChromosome>

. This class applies local search on a test suite. Depending on the values for properties DSE_PROBABILITY and LOCAL_SEARCH_DSE one of the following three modes is applied: - apply DSE on all test cases - apply AVM on all test cases - apply DSE on some tests and AVM on other tests

boolean	doSearch(TestSuiteChromosome suite, LocalSearchObjective<TestSuiteChromosome> objective) Applies local search to the suite targeting the objective passed as parameter.
protected static void	ensureDoubleExecution(TestSuiteChromosome individual, LocalSearchObjective<TestSuiteChromosome> objective) Ensure that all branches are executed twice For each branch such that exists only one test case in the suite that covers that branch, it creates a duplicate of that test case.
static TestSuiteLocalSearch	selectTestSuiteLocalSearch() Decides the kind of local search that will be applied to the Test Suite.

Method Detail

selectTestSuiteLocalSearch

public static TestSuiteLocalSearch selectTestSuiteLocalSearch()

Decides the kind of local search that will be applied to the Test Suite.

Returns:

a TestSuiteLocalSearch instance to use for local search

ensureDoubleExecution

protected static void ensureDoubleExecution(TestSuiteChromosome individual,
                                            LocalSearchObjective<TestSuiteChromosome> objective)

Ensure that all branches are executed twice For each branch such that exists only one test case in the suite that covers that branch, it creates a duplicate of that test case. By doing this, we avoid to incorrectly mark a new test case produced by the local search as an improving test case because it simply executes again a predicate.

doSearch

public boolean doSearch(TestSuiteChromosome suite,
                        LocalSearchObjective<TestSuiteChromosome> objective)

Applies local search to the suite targeting the objective passed as parameter. The type of local search will be decided according to the DSE_PROBABITY and LOCAL_SEARCH_DSE properties.

Specified by:

doSearch in interface LocalSearch<TestSuiteChromosome>

Parameters:

suite - the test suite to apply local search on

objective - the local search objective

Returns:

true iff the test suite has improved.
