## Running the tests
Many of the tests require privileges to set resource limits and load eBPF code.
The easiest way to obtain these is to run the tests with `sudo`:
The easiest way to obtain these is to run the tests with `sudo`.
To test the current package with your local kernel you can simply run:
```
go test -exec sudo ./...
```
To test the current package with a different kernel version you can use the [run-tests.sh](run-tests.sh) script.
It requires [virtme](https://github.com/amluto/virtme) and qemu to be installed.
Examples:
```bash
# Run all tests on a 5.4 kernel
./run-tests.sh 5.4
# Run a subset of tests:
./run-tests.sh 5.4 go test ./link
```
sudo go test ./...
