Direct Known Subclasses:

SolverBasedTest0.ParameterizedSolverBasedTest0
```
public abstract class SolverBasedTest0
extends Object
```
Abstract base class with helpful utilities for writing tests that use an SMT solver. It instantiates and closes the SMT solver before and after each test, and provides fields with direct access to the most relevant instances.
To run the tests using all available solvers, add the following code to your class:
```
 
  @Parameters(name="{0}")
  public static List<Object[]> getAllSolvers() {
    return allSolversAsParameters();
  }

  @Parameter(0)
  public Solvers solver;

  @Override
  protected Solvers solverToUse() {
    return solver;
  }
 
 
```
assertThatFormula(BooleanFormula) can be used to easily write assertions about formulas using Truth.
Test that rely on a theory that not all solvers support should call one of the require methods at the beginning.

shutdownNotifierToUse

protected ShutdownNotifier shutdownNotifierToUse()

solverToUse
```
protected SolverContextFactory.Solvers solverToUse()
```
Return the solver to use in this test. The default is SMTInterpol because it's the only solver guaranteed on all platforms. Overwrite to specify a different solver.

requireIntegers
```
protected final void requireIntegers()
```
Skip test if the solver does not support integers.

requireRationals
```
protected final void requireRationals()
```
Skip test if the solver does not support rationals.

requireBitvectors
```
protected final void requireBitvectors()
```
Skip test if the solver does not support bitvectors.

protected final void requireOptimization()
```
Skip test if the solver does not support optimization.

assertThatEnvironment
```
protected final ProverEnvironmentSubject assertThatEnvironment(BasicProverEnvironment<?> prover)
```
Use this for checking assertions about ProverEnvironments with Truth: assertThatEnvironment(stack).is...().
For new code, we suggest using ProverEnvironmentSubject.assertThat(BasicProverEnvironment) with a static import.
