Bats is most useful when testing software written in Bash, but you can
use it to test any UNIX program.
### The `run` helper
### The _run_ helper
You're probably most interested in testing a command's exit status and
output. Bats includes a `run` helper that invokes its arguments as a
command, saves the exit status and output into special global
variables, and then returns with a `0` exit status so you can continue
variables, and then returns with a `0` status code so you can continue
to make assertions in your test case.
For example, let's say you're testing that the `foo` command, when

### 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.
