This adds a new build tag named rpctest which must be set in order for
rpctest-based tests to be executed. The new build tag is also added to
the goclean.sh script which is executed by Travis during continuous
integration builds.
This change is being made because the rpctest framework requires
additional careful user configuration to ensure the version of btcd
under test can be programmatically launched from the system path with
all of the necessary ports open whereas all of the other tests are
self-contained within the test binary itself.
Since said additional configuration is typically not done, it leads to a
lot of false positives. Putting the tests behind a build tag allows
them to remain to be available and run during continuous integration
without imposing the additional configuration requirements on users.
This modifies the rpctest harness to call the TearDown function in the
SetUp error path. This ensures any resources, such as temp directories,
that were created during setup before whatever the failure that caused
the error are properly cleaned up.
This commit modifies the current set of integration tests to ensure
that that the main harness always rejects non-standard transactions.
With this in place, even though we’re using simnet parameters, we
ensure that transaction acceptance/validation is identical to that of
main net.
This commit adds a `defer` statement at the top of `TestRpcServer`
which will attempt a `recover` which tears down all active harnesses in
the event that one of the tests causes a panic in the main goroutine.
Before this commit, if a buggy test caused a panic while all integration
tests were being executed, then any active harnesses would fail to be
properly torn down. This would cause the running btcd processes to be
leaked, possibly interfering with future test runs until the process was
manually killed. This commit fixes such behavior.
In order to aide in debugging, when a test panics, the test number is
printed out along with a full stack-trace from the start of the test to
the panic point.
This commit introduces a new file: rpcserver_test.go dedicated for
including integration tests for btcd using the new rpctest package.
The tests are created using a TestMain instance first creates a single
main harness which is intended to be re-used across tests instances.
Afterwards all registered RPC tests are executed, with proper clean up
being executed regardless of the passing state of the tests.
The following RPC calls are excessed by the initial set of tests added:
* getbestblock
* getblockcount
* getblockhash
