This commit adds a basic test to exercise the scenario of forced
channel closure between to nodes with an existing channel open. The
test ensures that the latest commitment transaction it broadcast to the
chain and additionally that all time-locked outputs are sweeped with a
single transaction as soon as the inputs are mature enough.
At times when testing one requires access to the logs of a particular
node in order to aide with debugging. Before this commit, one needed to
manually modify the networkHarness code in order to print either the
location of the logs or the logs themselves. With this commit, tests
can now programmatically examine the logs of any node created within
the networkHarness.
It’s worth noting that at times the logs dumped may not be the most up
to date version of the logs files as the logging library employs
intermediate buffering.
This commit fixes some flakiness exhibited in the current basic funding
workflow tests. This test can fail occasionally in resource constrained
environment due to a race condition which arises after Alice learns of
the channel, but Bob is still waiting for Alice’s notification. As a
temporary fix, we now only check Alice’s state for the existence of the
channel.
This commit adds some new networkHarness helper methods which are
mean’t to reduce the verbosity of the previous basic tests, and also to
enable developers to right tests mote easily five a higher level
interface.
This commit increases the robustness of the current test and also
reduces it’s running time considerably as all “time.Sleep”s have now
been removed.
Rather than sleeping some random amount of time, the test now waits for
a particular async notification to be dispatched before proceeding.
This tightens up the execution of the tests quite a bit.
This commit adds a new feature to the network harness enabling callers
to receive async notifications once a particular transaction is seen on
the network. Such a feature is useful when due to the asynchronous
behavior of node communications.
With this new feature, tests can now wait for a particular transaction
to be seen within the network before proceeding.
This commit fixes the build for version 1.6.3 of golang. In go 1.7, the
“context” package was moved into the standard library, however go 1.6.3
doesn’t have that change, so we must refer to the prior WIP package
until a new version of Go is released.
