Modify the `XChainBridge` amendment. Before this patch, two door accounts on the same chain could could own the same bridge spec (of course, one would have to be the issuer and one would have to be the locker). While this is silly, it does not violate any bridge invariants. However, on further review, if we allow this then the `claim` transactions would need to change. Since it's hard to see a use case for two doors to own the same bridge, this patch disallows it. (The transaction will return tecDUPLICATE).
Unit Tests
Running Tests
Unit tests are bundled in the rippled executable and can be executed using the
--unittest parameter. Without any arguments to this option, all non-manual
unit tests will be executed. If you want to run one or more manual tests, you
must specify it by suite or full-name (e.g. ripple.app.NoRippleCheckLimits or
just NoRippleCheckLimits).
More than one suite or group of suites can be specified as a comma separated
list via the argument. For example, --unittest=beast,OversizeMeta will run
all suites in the beast library (root identifier) as well as the test suite
named OversizeMeta). All name matches are case sensitive.
Tests can be executed in parallel using several child processes by specifying
the --unittest-jobs=N parameter. The default behavior is to execute serially
using a single process.
The order that suites are executed is determined by the suite priority that
is optionally specified when the suite is declared in the code with one of the
BEAST_DEFINE_TESTSUITE macros. By default, suites have a priority of 0, and
other suites can choose to declare an integer priority value to make themselves
execute before or after other suites based on their specified priority value.
By default, the framework will emit the name of each testcase/testsuite when it
starts and any messages sent to the suite log stream. The --quiet option will
suppress both types of messages, but combining --unittest-log with --quiet
will cause log messages to be emitted while suite/case names are suppressed.
