The [`run-tests.sh`](./run-tests.sh) command is most convenient and versatile way to run tests.\
|
|
It leave no traces (outside of `/nix/store`) on the host system.
|
|
|
|
`run-tests.sh` requires Nix >= 2.10.
|
|
|
|
### Summary
|
|
```bash
|
|
./run-tests.sh [--scenario|-s <scenario>] [build|vm|debug|container]
|
|
```
|
|
|
|
See the top of [run-tests.sh](../test/run-tests.sh) for a complete documentation.\
|
|
Test scenarios are defined in [tests.nix](./tests.nix) and [tests.py](tests.py).
|
|
|
|
### Tutorial
|
|
#### Running tests
|
|
```bash
|
|
# Run the basic set of tests. These tests are also run on the GitHub CI server.
|
|
./run-tests.sh
|
|
|
|
# Run the test for scenario `regtest`.
|
|
# The test is run via the Nix build system. Successful runs are cached.
|
|
./run-tests.sh -s regtest build
|
|
./run-tests.sh -s regtest # Shorthand, equivalent
|
|
|
|
# To test a single service, use its name as a scenario.
|
|
./run-tests.sh -s clightning
|
|
|
|
# When no scenario is specified, scenario `default` is used.
|
|
./run-tests.sh build
|
|
```
|
|
#### Debugging
|
|
```bash
|
|
# Start a shell is inside a test VM. No tests are executed.
|
|
./run-tests.sh -s bitcoind vm
|
|
systemctl status bitcoind
|
|
|
|
# Run a Python NixOS test shell inside a VM.
|
|
# See https://nixos.org/manual/nixos/stable/#ssec-machine-objects for available commands.
|
|
./run-tests.sh debug
|
|
print(succeed("systemctl status bitcoind"))
|
|
run_test("bitcoind")
|
|
|
|
# Start a shell in a container node. Requires systemd and root privileges.
|
|
./run-tests.sh container
|
|
|
|
# In the container shell: Run command in container (with prefix `c`)
|
|
c systemctl status bitcoind
|
|
|
|
# Explore a single feature
|
|
./run-tests.sh -s electrs container
|
|
|
|
# Run a command in a container.
|
|
# The container is deleted afterwards.
|
|
./run-tests.sh -s clightning container --run c lightning-cli getinfo
|
|
|
|
# Define a custom scenario
|
|
./run-tests.sh --scenario '{
|
|
services.clightning.enable = true;
|
|
nix-bitcoin.nodeinfo.enable = true;
|
|
}' container --run c nodeinfo
|
|
```
|
|
|
|
# Running tests with Flakes
|
|
|
|
Tests can also be accessed via the nix-bitcoin flake:
|
|
|
|
```bash
|
|
# Build test
|
|
nix build --no-link ..#tests.default
|
|
|
|
# Run a node in a VM. No tests are executed.
|
|
nix run ..#tests.default.vm
|
|
|
|
# Run a Python test shell inside a VM node
|
|
nix run ..#tests.default.run -- --debug
|
|
|
|
# Run a node in a container. Requires extra-container, systemd and root privileges
|
|
nix run ..#tests.default.container
|
|
nix run ..#tests.default.containerLegacy # For NixOS with `system.stateVersion` <22.05
|
|
|
|
# Run a command in a container
|
|
nix run ..#tests.default.container -- --run c nodeinfo
|
|
nix run ..#tests.default.containerLegacy -- --run c nodeinfo # For NixOS with `system.stateVersion` <22.05
|
|
```
