# Testing Isle

All tests are currently written as go tests, and as such can be run from the
`go` directory using the normal go testing tool.

```
cd go
go test -run Foo ./daemon
go test ./... # Test everything
```

## Integration Tests

Integration tests are those which require processes or state external to the
test itself. Integration tests are marked using the
`toolkit.MarkIntegrationTest` function, which will cause them to be skipped
unless being run in the integration test environment.

Besides a normal nix installation (like all Isle development needs), integration
tests also require `sudo` and [capsh][capsh] to be installed on the system.

[capsh]: https://www.man7.org/linux/man-pages/man1/capsh.1.html

By running tests using the `go/integration_test.sh` script the tests will be
automatically run in the integration test environment. All arguments will be
passed directly to the go testing tool.

```
cd go
./integration_test.sh -run Foo ./daemon
```

`integration_test.sh` wraps a call to `go test` in a bash shell which has all
required binaries available to it, and which has acquired necessary
[capabilities][capabilities] to use the binaries as needed. Acquiring
capabilities is done by elevating the user to root using `sudo`, and then
dropping them back down to a shell of the original user with capabilities set.
