+The [pull-tester](/qa/pull-tester/) folder contains a script to call
+multiple tests from the [rpc-tests](/qa/rpc-tests/) folder.
+
+Every pull request to the bitcoin repository is built and run through
+the regression test suite. You can also run all or only individual
+tests locally.
+
+Running tests
+=============
+
+You can run any single test by calling `qa/pull-tester/rpc-tests.py <testname>`.
+
+Or you can run any combination of tests by calling `qa/pull-tester/rpc-tests.py <testname1> <testname2> <testname3> ...`
+
+Run the regression test suite with `qa/pull-tester/rpc-tests.py`
+
+Run all possible tests with `qa/pull-tester/rpc-tests.py -extended`
+
+Possible options:
+
+```
+ -h, --help show this help message and exit
+ --nocleanup Leave bitcoinds and test.* datadir on exit or error
+ --noshutdown Don't stop bitcoinds after the test execution
+ --srcdir=SRCDIR Source directory containing bitcoind/bitcoin-cli
+ (default: ../../src)
+ --tmpdir=TMPDIR Root directory for datadirs
+ --tracerpc Print out all RPC calls as they are made
+ --coveragedir=COVERAGEDIR
+ Write tested RPC commands into this directory
+```
+
+If you set the environment variable `PYTHON_DEBUG=1` you will get some debug
+output (example: `PYTHON_DEBUG=1 qa/pull-tester/rpc-tests.py wallet`).
+
+A 200-block -regtest blockchain and wallets for four nodes
+is created the first time a regression test is run and
+is stored in the cache/ directory. Each node has 25 mature
+blocks (25*50=1250 BTC) in its wallet.
+
+After the first run, the cache/ blockchain and wallets are
+copied into a temporary directory and used as the initial
+test state.
+
+If you get into a bad state, you should be able
+to recover with:
+
+```bash
+rm -rf cache
+killall bitcoind
+```
+
+Writing tests
+=============
+You are encouraged to write tests for new or existing features.
+Further information about the test framework and individual rpc
+tests is found in [qa/rpc-tests](/qa/rpc-tests).
