Class TruthJUnit

java.lang.Object

com.google.common.truth.TruthJUnit

@GwtIncompatible(value="JUnit4")
public class TruthJUnit
extends Object

Truth - a proposition framework for tests, supporting JUnit style assertion and assumption semantics in a fluent style.

TruthJUnit contains a junit-specific "failure strategy" known as an assumption. An assumption is a proposition that, if the proposition is false, aborts (skips) the test. This is especially useful in JUnit theories or parameterized tests, or other combinatorial tests where some subset of the combinations are simply not applicable for testing.

TruthJUnit is the entry point for assumptions, via the assume() method.

eg:

 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);
 }
