+# 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.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`.
+

+# Avoiding bitcoin-core regtest port conflicts
+
+Some developers may already be running a `bitcoind` or `bitcoin-qt` instance in regtest mode when they try to run API
+test cases.  If a `bitcoin-qt` instance is bound to the default regtest port 18444, `apitest` will not be able to start
+its own bitcoind instances.
+
+Though it would be preferable for `apitest` to change the bind port for Bisq's `bitcoinj` module at runtime, this is
+not currently possible because `bitcoinj` hardcodes the default regtest mode bind port in `RegTestParams`.
+
+To avoid the bind address:port conflict, pass a port option to your bitcoin-core instance:
+
+    bitcoin-qt -regtest -port=20444

+# API Test Categories
+
+This guide describes the categorization of tests.
+
+## Method Tests
+
+A `method` test is the `apitest` analog of a unit test.  It tests a single API method such as `getbalance`, but is not
+considered a unit test because the code execution path traverses so many layers:  from `gRPC` client -> `gRPC` server
+side service -> one or more Bisq `core` services, and back to the client.
+
+Method tests have direct access to `gRPC` client stubs, and test asserts are made directly on `gRPC` return values --
+Java Objects.
+
+All `method` tests are part of the `bisq.apitest.method` package.
+
+## Scenario Tests
+
+A `scenario` test is a narrow or broad functional test case covering a simple use case such as funding a wallet to a
+complex series of trades.  Generally, a scenario test case requires multiple `gRPC` method calls.
+
+Scenario tests have direct access to `gRPC` client stubs, and test asserts are made directly on `gRPC` return values --
+Java Objects.
+
+All `scenario` tests are part of the `bisq.apitest.scenario` package.
+
+## End to End Tests
+
+An end to end (`e2e`) test can cover a narrow or broad use case, and all client calls go through the `CLI` shell script
+`bisq-cli`.  End to end tests do not have access to `gRPC` client stubs, and test asserts are made on what the end
+user sees on the console -- what`gRPC CLI` prints to `STDOUT`.
+
+As test coverage grows, stable scenario test cases should be migrated to `e2e` test cases.
+
+All `e2e` tests are part of the `bisq.apitest.e2e` package.
