/**
 * Provides a way to use Truth to perform JUnit "assumptions." An assumption is a check that, if
 * false, aborts (skips) the test. This is especially useful in JUnit theories, parameterized tests,
 * or other combinatorial tests where some subset of the combinations are simply not applicable for
 * testing.
 *
 * <p>For example:
 *
 * <pre>{@code
 * import static com.google.common.truth.Truth.assertThat;
 * import static com.google.common.truth.TruthJUnit.assume;
 *
 * public void @Test testFoosAgainstBars {
 *   assume().that(foo).isNotNull();
 *   assume().that(bar).isNotNull();
 *   assertThat(foo.times(bar)).isEqualTo(blah);
 * }
 * }</pre>
