How to be started for development

BTCPay Server tests depend on having a proper environment running with Postgres, Bitcoind, NBxplorer configured. You can however use the BTCPayServer.Tests/docker-compose.yml to get it running.

In addition, when you run a debug session of BTCPay (Hitting F5 on Visual Studio Code or Visual Studio 2017), it will run the launch profile called Docker-Regtest. This launch profile depends on this docker-compose running.

This is running a bitcoind instance on regtest, a private bitcoin blockchain for testing on which you can generate blocks yourself.

docker-compose up dev

You can run the tests while it is running through your favorite IDE, or with

dotnet test

Once you want to stop

docker-compose down

If you want to stop, and remove all existing data

docker-compose down --v

You can run tests on MySql database instead of Postgres by setting environnement variable TESTS_DB equals to MySql.

How to test altcoins

Follow the above instruction except the docker-compose command should be docker-compose -f docker-compose.altcoins.yml.

This will run monero, ltc and liquid dependencies.

How to manually test payments

Using the test bitcoin-cli

You can call bitcoin-cli inside the container with docker exec. For example, if you want to send 0.23111090 to mohu16LH66ptoWGEL1GtP6KHTBJYXMWhEf:

./docker-bitcoin-cli.sh sendtoaddress "mohu16LH66ptoWGEL1GtP6KHTBJYXMWhEf" 0.23111090

If you are using Powershell:

.\docker-bitcoin-cli.ps1 sendtoaddress "mohu16LH66ptoWGEL1GtP6KHTBJYXMWhEf" 0.23111090

You can also generate blocks:

.\docker-bitcoin-generate.ps1 3

Using the test litecoin-cli

Same as bitcoin-cli, but with .\docker-litecoin-cli.ps1 and .\docker-litecoin-cli.sh instead.

Using the test lightning-cli

If you are using Linux:

./docker-customer-lightning-cli.sh pay lnbcrt100u1pd2e6uspp5ajnadvhazjrz55twd5k6yeg9u87wpw0q2fdr7g960yl5asv5fmnqdq9d3hkccqpxmedyrk0ehw5ueqx5e0r4qrrv74cewddfcvsxaawqz7634cmjj39sqwy5tvhz0hasktkk6t9pqfdh3edmf3z09zst5y7khv3rvxh8ctqqw6mwhh

If you are using Powershell:

.\docker-customer-lightning-cli.ps1 pay lnbcrt100u1pd2e6uspp5ajnadvhazjrz55twd5k6yeg9u87wpw0q2fdr7g960yl5asv5fmnqdq9d3hkccqpxmedyrk0ehw5ueqx5e0r4qrrv74cewddfcvsxaawqz7634cmjj39sqwy5tvhz0hasktkk6t9pqfdh3edmf3z09zst5y7khv3rvxh8ctqqw6mwhh

If you get this message:

{ "code" : 205, "message" : "Could not find a route", "data" : { "getroute_tries" : 1, "sendpay_tries" : 0 } }

Please, run the test CanSetLightningServer, this will establish a channel between the customer and the merchant, then, retry.

FAQ

docker-compose up dev failed or tests are not passing, what should I do?

Run docker-compose down --v (this will reset your test environment)
Run docker-compose pull (this will ensure you have the lastest images)
Run again with docker-compose up dev

If you still have issues, try to restart docker.
