java.lang.Object org.junit.rules.RuleChain
@Deprecated public class RuleChain
The RuleChain rule allows ordering of TestRules. You create a
RuleChain
with outerRule(TestRule)
and subsequent calls of
around(TestRule)
:
public class UseRuleChain { @Rule public RuleChain chain= RuleChain .outerRule(new LoggingRule("outer rule")) .around(new LoggingRule("middle rule")) .around(new LoggingRule("inner rule")); @Test public void example() { assertTrue(true); } }writes the log
starting outer rule starting middle rule starting inner rule finished inner rule finished middle rule finished outer rule
RuleChain
cannot be used to define the order of existing rules.
For example in the below snippet the LoggingRule middle
would be
executed outside as well as inside the RuleChain
:
@Rule public LoggingRule middle = new LoggingRule("middle rule"); @Rule public RuleChain chain = RuleChain .outerRule(new LoggingRule("outer rule")) .around(middle) .around(new LoggingRule("inner rule"));
