public interface Circuit
A Circuit is the basic test unit against which test cases are to be written. A circuit consists of two 'ends', an instigating 'publisher' end and a more passive 'receivers' end.
Once created, the life-cycle of a circuit may be controlled bystart()
ing it, or close()
ing it.
Once started, the circuit is ready to send messages over. Once closed the circuit can no longer be used.
The state of the circuit may be taken with the check()
method, and asserted against by the
applyAssertions(java.util.List)
method.
There is a default test procedure which may be performed against the circuit. The outline of this procedure is:
Start the circuit. Send test messages. Request a status report. Assert conditions on the publishing end of the circuit. Assert conditions on the receiving end of the circuit. Close the circuit. Pass with no failed assertions or fail with a list of failed assertions.
Responsibilities |
---|
Supply the publishing and receiving ends of a test messaging circuit. |
Start the circuit running. |
Close the circuit down. |
Take a reading of the circuits state. |
Apply assertions against the circuits state. |
Send test messages over the circuit. |
Perform the default test procedue on the circuit. |
Method Summary | |
---|---|
List<Assertion> |
applyAssertions(List<Assertion> assertions)
Applied a list of assertions against the test circuit. |
void |
check()
Checks the test circuit. |
void |
close()
Closes the circuit. |
Publisher |
getPublisher()
Gets the interface on the publishing end of the circuit. |
Receiver |
getReceiver()
Gets the interface on the receiving end of the circuit. |
void |
start()
Connects and starts the circuit. |
List<Assertion> |
test(int numMessages,
List<Assertion> assertions)
Runs the default test procedure against the circuit, and checks that all of the specified assertions hold. |
Method Detail |
---|
Publisher getPublisher()
Receiver getReceiver()
void start()
void check()
void close()
List<Assertion> applyAssertions(List<Assertion> assertions)
check()
method should be called before doing
this, to ensure that the circuit has gathered its state into a report to assert against.
assertions
- The list of assertions to apply to the circuit.
List<Assertion> test(int numMessages, List<Assertion> assertions)
numMessages
- The number of messages to send using the default test procedure.assertions
- The list of assertions to apply.
