# Build and Run API Test Harness

## Linux & OSX

The API test harness uses the GNU Bourne-Again SHell `bash`, and is not supported on Windows.

## Predefined DAO / Regtest Setup

The API test harness depends on the contents of https://github.com/bisq-network/bisq/raw/master/docs/dao-setup.zip.
The files contained in dao-setup.zip include a bitcoin-core wallet, a regtest genesis tx and chain of 111 blocks, plus
data directories for Bob and Alice Bisq instances.  Bob & Alice wallets are pre-configured with 10 BTC each, and the
equivalent of 2.5 BTC in BSQ distributed among Bob & Alice's BSQ wallets.

See https://github.com/bisq-network/bisq/blob/master/docs/dao-setup.md for details.

## Install DAO / Regtest Setup Files

Bisq's gradle build file defines a task for downloading dao-setup.zip and extracting its contents to the
`apitest/src/main/resources` folder, and the test harness will install a fresh set of data files to the
`apitest/build/resources/main` folder during a test case's scaffold setup phase -- normally a static `@BeforeAll` method.

The dao-setup files can be downloaded during a normal build:

    $ ./gradlew clean build :apitest:installDaoSetup

Or by running a single task:

    $ ./gradlew :apitest:installDaoSetup

The `:apitest:installDaoSetup` task does not need to be run again until after the next time you run the gradle `clean` task.

## Run API Tests

The API test harness supports narrow & broad functional and full end to end test cases requiring
long setup and teardown times -- for example, to start a bitcoind instance, seednode, arbnode, plus Bob & Alice
Bisq instances, then shut everything down in proper order.  For this reason, API test cases do not run during a normal
gradle build.

To run API test cases, pass system property`-DrunApiTests=true`.

To run all existing test cases:

    $ ./gradlew  :apitest:test -DrunApiTests=true

To run all test cases in a package:

    $ ./gradlew  :apitest:test --tests "bisq.apitest.method.*" -DrunApiTests=true

To run a single test case:

    $ ./gradlew  :apitest:test --tests "bisq.apitest.method.wallet.GetBalanceTest" -DrunApiTests=true

To run test cases from Intellij, add two JVM arguments to your JUnit launchers:

    -DrunApiTests=true -Dlogback.configurationFile=apitest/build/resources/main/logback.xml

The `-Dlogback.configurationFile` property will prevent `logback` from printing warnings about multiple `logback.xml`
files it will find in Bisq jars `cli.jar`, `daemon.jar`, and `seednode.jar`.
