stellar-core

Stellar-core is a replicated state machine that maintains a local copy of a cryptographic ledger and processes transactions against it, in consensus with a set of peers. It implements the Stellar Consensus Protocol, a federated consensus protocol. It is written in C++11 and runs on Linux, OSX and Windows. Learn more by reading the overview document.

Running tests

run tests with: src/stellar-core --test

run one test with: src/stellar-core --test testName

run one test category with: src/stellar-core --test '[categoryName]'

Categories (or tags) can be combined: AND-ed (by juxtaposition) or OR-ed (by comma-listing).

Tests tagged as [.] or [hide] are not part of the default test test.

supported test options can be seen with src/stellar-core --test --help

display tests timing information: src/stellar-core --test -d yes '[categoryName]'

xml test output (includes nested section information): src/stellar-core --test -r xml '[categoryName]'

Running tests against postgreSQL

There are two options. The easiest is to have the test suite just create a temporary postgreSQL database cluster in /tmp and delete it after the test. That will happen by default if you run make check.

You can also create a temporary database cluster manually, by running ./src/test/selftest-pg bash to get a shell, then running tests manually. The advantage of this is that you can examine the database log in $PGDATA/pg_log/ after running tests, as well as manually inspect the database with psql.

Finally, you can use an existing database cluster so long as it has databases named test0, test1, ..., test8, and test. Do set this up, make sure your PGHOST and PGUSER environment variables are appropriately set, then run the following from bash:

for i in $(seq 0 8) ''; do
    psql -c "create database test$i;"
done

Running stress tests

We adopt the convention of tagging a stress-test for subsystem foo as [foo-stress][stress][hide].

Then, running

• stellar-core --test [stress] will run all the stress tests,
• stellar-core --test [foo-stress] will run the stress tests for subsystem foo alone, and
• neither stellar-core --test nor stellar-core --test [foo] will run stress tests.
