@GwtIncompatible(value="JUnit4") public final class Expect extends StandardSubjectBuilder implements TestRule
TestRule that batches up all failures encountered during a test, and reports them all
together at the end (similar to ErrorCollector). It is also useful for making assertions
from other threads or from within callbacks whose exceptions would be swallowed or logged, rather
than propagated out to fail the test. (AssertJ has a similar feature called "soft assertions"; however, soft
assertions are not safe for concurrent use.)
Usage:
If both of the assertions above fail, the test will fail with an exception that contains information about both.@Rule public final Expect expect = Expect.create();...expect.that(results).containsExactly(...);expect.that(errors).isEmpty();
Expect may be used concurrently from multiple threads. Note, however, that Expect has no way of knowing when all your other test threads are done. It simply checks for
failures when the main thread finishes executing the test method. Thus, you must ensure that any
background threads complete their assertions before then, or your test may ignore their results.
To record failures for the purpose of testing that an assertion fails when it should, see
ExpectFailure.
