# Modules integration test runner.
|
|
# The tests (defined in ./tests.nix) use the NixOS testing framework and are executed in a VM.
|
|
#
|
|
# Usage:
|
|
# Run all tests
|
|
# ./run-tests.sh
|
|
#
|
|
# Test specific scenario
|
|
# ./run-tests.sh --scenario|-s <scenario>
|
|
#
|
|
# - When <scenario> contains a space, <scenario> is treated as nix code defining
|
|
# a scenario. It is evaluated in the same context as other scenarios in ./tests.nix
|
|
#
|
|
# Example:
|
|
# ./run-tests.sh -s "{ nix-bitcoin.nodeinfo.enable = true; }" container --run c nodeinfo
|
|
#
|
|
# - When <scenario> does not name a scenario, the test is run with an adhoc scenario
|
|
# where services.<scenario> is enabled.
|
|
#
|
|
# Example:
|
|
# ./run-tests.sh -s electrs
|
|
#
|
|
# Run test(s) and link results to avoid garbage collection
|
|
# ./run-tests.sh [--scenario <scenario>] --out-link-prefix /tmp/nix-bitcoin-test
|
|
#
|
|
# Pass extra args to nix-build
|
|
# ./run-tests.sh build --builders 'ssh://mybuildhost - - 15'
|
|
#
|
|
# Run interactive test debugging
|
|
# ./run-tests.sh [--scenario <scenario>] debug
|
|
#
|
|
# This starts the testing VM and drops you into a Python REPL where you can
|
|
# manually execute the tests from ./tests.py
|
|
#
|
|
# Run a test scenario in a container
|
|
# sudo ./run-tests.sh [--scenario <scenario>] container
|
|
#
|
|
# This is useful for quick experiments; containers start much faster than VMs.
|
|
# Running the Python test suite in containers is not yet supported.
|
|
# For now, creating NixOS containers requires root permissions.
|
|
# See ./lib/make-container.sh for a complete documentation.
|
|
#
|
|
# Run a test scenario in a regular NixOS VM.
|
|
# No tests are executed, the machine's serial console is attached to your terminal.
|
|
# ./run-tests.sh [--scenario <scenario>] vm
|
|
#
|
|
# This is useful for directly exploring a test configuration without the
|
|
# intermediate Python REPL layer.
|
|
# Run command 'q' inside the machine for instant poweroff.
|
|
#
|
|
# Run tests from a snapshot copy of the source files
|
|
# ./run-tests.sh --copy-src|-c ...
|
|
#
|
|
# This allows you to continue editing the nix-bitcoin sources while tests are running
|
|
# and reading source files.
|
|
# Files are copied to /tmp, a caching scheme helps minimizing copies.
|
|
#
|
|
# To add custom scenarios, set the environment variable `scenarioOverridesFile`.
