Class TruthJUnit

java.lang.Object

com.google.common.truth.TruthJUnit

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

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.

For example:

 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);
 }

Method Summary

Modifier and Type	Method and Description
static StandardSubjectBuilder	assume() Begins a call chain with the fluent Truth API.
static FailureStrategy	throwAssumptionError() Deprecated. If you are passing this to a Subject constructor, instead call assume().about(...).that(...), passing its associated SubjectFactory (which you might need to create). If you are calling fail on this object directly, instead use assume().fail(), or throw new AssumptionViolatedException() directly.

Method Detail

throwAssumptionError

@Deprecated
public static final FailureStrategy throwAssumptionError()

Deprecated. If you are passing this to a Subject constructor, instead call assume().about(...).that(...), passing its associated SubjectFactory (which you might need to create). If you are calling fail on this object directly, instead use assume().fail(), or throw new AssumptionViolatedException() directly.

assume

public static final StandardSubjectBuilder assume()

Begins a call chain with the fluent Truth API. If the check made by the chain fails, it will throw AssumptionViolatedException.
