Class BooleanFormulaSubject

java.lang.Object

com.google.common.truth.Subject

org.sosy_lab.java_smt.test.BooleanFormulaSubject

public final class BooleanFormulaSubject
extends Subject

Subject subclass for testing assertions about BooleanFormulas with Truth (allows using assert_().about(...).that(formula).isUnsatisfiable() etc.).

For a test use either SolverBasedTest0.assertThatFormula(BooleanFormula), or use StandardSubjectBuilder.about(com.google.common.truth.Subject.Factory) and set a solver via the method booleanFormulasOf(SolverContext).

Method Details

booleanFormulasOf

public static Subject.Factory<BooleanFormulaSubject,BooleanFormula> booleanFormulasOf(SolverContext context)

Use this for checking assertions about BooleanFormulas (given the corresponding solver) with Truth: assert_().about(booleanFormulasOf(context)).that(formula).is...().

assertUsing

public static SimpleSubjectBuilder<BooleanFormulaSubject,BooleanFormula> assertUsing(SolverContext context)

Use this for checking assertions about BooleanFormulas (given the corresponding solver) with Truth: assertUsing(context)).that(formula).is...().

isUnsatisfiable

public void isUnsatisfiable()
                     throws SolverException,
InterruptedException

Check that the subject is unsatisfiable. Will show a model (satisfying assignment) on failure.

Throws:

SolverException

InterruptedException

isSatisfiable

public void isSatisfiable()
                   throws SolverException,
InterruptedException

Check that the subject is satisfiable. Will show an unsat core on failure.

Throws:

SolverException

InterruptedException

isTautological

public void isTautological()
                    throws SolverException,
InterruptedException

Check that the subject is tautological, i.e., always holds. This is equivalent to calling isEquivalentTo(BooleanFormula) with the formula true, but it checks satisfiability of the subject and unsatisfiability of the negated subject in two steps to improve error messages.

Throws:

SolverException

InterruptedException

isEquivalentTo

public void isEquivalentTo(BooleanFormula expected)
                    throws SolverException,
InterruptedException

Check that the subject is equivalent to a given formula, i.e. subject <=> expected always holds. Will show a counterexample on failure.

Throws:

SolverException

InterruptedException

isEquisatisfiableTo

public void isEquisatisfiableTo(BooleanFormula other)
                         throws SolverException,
InterruptedException

Throws:

SolverException

InterruptedException

implies

public void implies(BooleanFormula expected)
             throws SolverException,
InterruptedException

Check that the subject implies a given formula, i.e. subject => expected always holds. Will show a counterexample on failure.

Throws:

SolverException

InterruptedException
