### The _load_ command
You may want to share common code across multiple test files. Bats
includes a convenient `load` command for sourcing a Bash source file
relative to the location of the current test file. For example, if you
have a Bats test in `test/foo.bats`, the command
```bash
load test_helper
```
will source the script `test/test_helper.bash` in your test file. This
can be useful for sharing functions to set up your environment or load
fixtures.
